Prevalence of generalised osteoarthritis in patients with advanced hip and knee osteoarthritis: the Ulm Osteoarthritis Study. (1/3222)
OBJECTIVES: Different prevalences of generalised osteoarthritis (GOA) in patients with knee and hip OA have been reported. The aim of this investigation was to evaluate radiographic and clinical patterns of disease in a hospital based population of patient subgroups with advanced hip and knee OA and to compare the prevalence of GOA in patients with hip or knee OA, taking potential confounding factors into account. METHODS: 420 patients with hip OA and 389 patients with knee OA scheduled for unilateral total joint replacement in four hospitals underwent radiographic analysis of ipsilateral and contralateral hip or knee joint and both hands in addition to a standardised interview and clinical examination. According to the severity of radiographic changes in the contralateral joints (using Kellgren-Lawrence > or = grade 2 as case definition) participants were classified as having either unilateral or bilateral OA. If radiographic changes of two joint groups of the hands (first carpometacarpal joint and proximal/distal interphalangeal joints defined as two separate joint groups) were present, patients were categorised as having GOA. RESULTS: Patients with hip OA were younger (mean age 60.4 years) and less likely to be female (52.4%) than patients with knee OA (66.3 years and 72.5% respectively). Intensity of pain and functional impairment at hospital admission was similar in both groups, while patients with knee OA had a longer symptom duration (median 10 years) compared with patients with hip OA (5 years). In 41.7% of patients with hip OA and 33.4% of patients with knee OA an underlying pathological condition could be observed in the replaced joint, which allowed a classification as secondary OA. Some 82.1% of patients with hip and 87.4% of patients with knee OA had radiographic changes in their contralateral joints (bilateral disease). The prevalence of GOA increased with age and was higher in female patients. GOA was observed more often in patients with knee OA than in patients with hip OA (34.9% versus 19.3%; OR = 2.24; 95% CI: 1.56, 3.21). Adjustment for the different age and sex distribution in both patient groups, however, takes away most of the difference (OR = 1.32; 95% CI: 0.89, 1.96). CONCLUSION: The crude results confirm previous reports as well as the clinical impression of GOA being more prevalent in patients with advanced knee OA than in patients with advanced hip OA. However, these different patterns might be attributed to a large part to a different distribution of age and sex in these hospital based populations. (+info)Down regulation by iron of prostaglandin E2 production by human synovial fibroblasts. (2/3222)
OBJECTIVE: To examine the effect of iron on the prostaglandin (PG) E2 production by human synovial fibroblasts in vitro. METHODS: Human synovial fibroblasts were isolated from synovial tissue of rheumatoid arthritis (RA) and osteoarthritis (OA) patients and cultured in medium. Synovial fibroblasts were stimulated by human recombinant interleukin (IL) 1 beta (0.1-10 ng/ml) with or without ferric citrate (Fe-citrate, 0.01-1 mM). The amount of PGE2 in the culture medium was measured by an enzyme linked immunosorbent assay. RESULTS: The production of PGE2 by the synovial fibroblasts was increased by stimulation with IL1 beta at all concentrations tested. Fe-citrate but not sodium citrate (Na-citrate) down regulated the production of PGE2 by the synovial fibroblasts, both with and without stimulation by IL1 beta. Fe-citrate inhibited the spontaneous PGE2 production by the cells in a dose dependent manner, and a maximum inhibition by Fe-citrate was observed at the concentration of 0.1 mM with IL1 beta stimulation. The down regulation by iron was reversed by the co-addition of desferrioxamine (100 micrograms/ml), an iron chelator. CONCLUSION: Iron down regulates the PGE2 production by synovial fibroblasts in vitro. (+info)Total knee replacement: should it be cemented or hybrid? (3/3222)
OBJECTIVE: To compare the complication rates associated with total knee arthroplasty against the types of fixation (hybrid or cemented), using a single total knee design (the anatomic modular knee [AMK] prosthesis). DESIGN: A prospective, nonrandomized, controlled trial. SETTING: University Hospital in London, Ont., a tertiary care teaching centre. PATIENTS: Two groups made up of 484 knees in 395 patients (89 bilateral). INTERVENTIONS: In 260 knees a hybrid configuration (cemented tibia and noncemented femur) was used (group 1). In 224 knees the femoral and tibial components were cemented (group 2). All patellae were cemented in both groups. MAIN OUTCOME MEASURES: Clinical results were assessed by The Knee Society Clinical Rating Scores at 3 months, 6 months and yearly intervals. Radiographic results were determined by 3-foot standing radiographs and at each follow-up visit standing knee radiographs, lateral and skyline views. Radiographs were analysed for alignment, presence or absence of radiolucent lines or changes in the position of the implant. All reoperations and nonoperative complications were recorded. RESULTS: At an average follow-up of 4.8 years, 8 knees (1.6%) required reoperation. An analysis of the complications leading to reoperation demonstrated no difference between the 2 groups. CONCLUSIONS: There was no difference in outcome whether the femoral component was cemented or not. Medium-term results of the AMK are excellent with a very low reoperation rate. (+info)Expression of NG2/human melanoma proteoglycan in human adult articular chondrocytes. (4/3222)
OBJECTIVE: NG2 is a transmembrane chondroitin sulfate (CS) rich proteoglycan originally identified in rats. It has recently been shown to be identical to human melanoma proteoglycan (HMPG). In rats NG2 has a limited distribution in adult tissues, being expressed predominantly by neuronal and glial cells whereas during development it is also expressed in developing mesenchyme including cartilage. NG2/HMPG has putative roles in interactions between glial and melanoma cells with extracellular matrix (ECM) molecules. This study was undertaken to assess whether NG2/HMPG was expressed by normal and osteoarthritic human articular chondrocytes. DESIGN: Cryostat sections of human fetal knee joints and normal and osteoarthritic articular cartilage were immunostained with antibodies against rat NG2 (N143.8) and HMPG (M28B5, 9.2.27). Immunoprecipitation and Western blotting was carried out on protein extracts of chondrocytes from normal and osteoarthritic cartilage. Immunofluorescence of NG2 and potential ligands was carried out in vitro on cells from normal and osteoarthritic cartilage. RESULTS: Fetal and both normal and osteoarthritic adult cartilage showed strong immunoreactivity for NG2/HMPG. Western blotting showed a smeared component of molecular weight greater than 400 kDa and a faint band at 250 kDa which became predominant upon digestion with chondroitinase ABC. Immunofluorescence of chondrocytes in vitro showed NG2 to be distributed in a punctate pattern without co-localization of actin or several ECM proteins including fibronectin and type VI collagen. CONCLUSION: NG2/HMPG is expressed by human fetal and adult chondrocytes and in adult articular chondrocytes the core protein is chondroitin sulfated. The function of this molecular in human articular cartilage remains to be defined. (+info)Where does it hurt? Pain localization in osteoarthritis of the knee. (5/3222)
OBJECTIVE: To identify the most common sites of pain in symptomatic knee osteoarthritis (OA) and to investigate clinical, radiographic and psychosocial associations of pain occurring in different locations. DESIGN: Sixty-eight outpatients with knee OA were interviewed in detail about their knee pain. Location of pain was recorded on a standard drawing of the knee. Validated instruments were used to measure pain severity, function, depression, anxiety, quality of life, fatigue, helplessness, self efficacy. Pain threshold was measured by dolorimetry and a knee examination performed. Radiographs (anterioposterior and lateral) were viewed if available. RESULTS: Most (85.3%) patients reported either 'generalized' (N = 35, 51.5%) or 'medial' (N = 23, 33.8%) knee pain. There were no differences between groups in pain severity, demographic or psychosocial variables, pain threshold or radiographic location or severity. However, function was significantly worse in the 'generalized' group (WOMAC function score 48.9 +/- 20.8 vs 34.2 +/- 22.3; P = 0.01): this remained significant after adjustment for potential confounding factors. The difference in function was most marked for activities involving knee bending. Early morning stiffness was also greater in the generalized group. CONCLUSIONS: Knee pain is not the same in all individuals with knee OA, confirming the heterogeneity of the condition. Location of pain is usually either generalized or medial. Patients with these patterns do not differ in demographic, radiographic or psychosocial variables but important differences in functional ability can be detected, suggesting differences in the underlying causes of pain and disability between the two groups. (+info)Longitudinal and cross-sectional variability in markers of joint metabolism in patients with knee pain and articular cartilage abnormalities. (6/3222)
OBJECTIVE: To determine the within- and between-patient variability in the concentrations of synovial fluid, serum and urine markers of joint tissue metabolism in a cohort of patients with knee pain and cartilage changes consistent with early-stage knee osteoarthritis. DESIGN: Samples of synovial fluid, serum, and urine were obtained from 52 patients on eight different occasions during 1 year, as part of a clinical trial in patients with cartilage abnormalities and knee pain. In joint fluid, aggrecan fragments were quantified by dye precipitation and enzyme-linked immunosorbent assay (ELISA), and matrix metalloproteinases-1 and -3, and tissue inhibitor of metalloproteinases-1 by sandwich ELISAs. In serum, keratan sulfate was quantified by ELISA. Type I collagen N-telopeptide cross-links in urine were determined by ELISA. RESULTS: The degree of cross-sectional variability in marker concentrations did not vary between the different sampling occasions, and did not differ between the periods of weeks 0 (baseline), 1-4 (treatment) and 13-26 (follow-up). Both between-patient and within-patient coefficients of variation varied for markers in different body fluid compartments, with the lowest variability for serum keratan sulfate, followed by urine type I collagen N-telopeptide crosslinks, and the highest for synovial fluid markers. For synovial fluid, aggrecan fragments showed the least variability, and matrix metalloproteinases the highest. One patient with septic arthritis showed a fivefold peak increase in joint fluid aggrecan fragment concentrations, while the concentration of matrix metalloproteinase-3 increased 100-fold. CONCLUSIONS: Molecular markers of joint tissue metabolism have been suggested as, for example, outcome measures for clinical trials of disease-modifying drugs in osteoarthritis. This report is the first to present data on between- and within-patient variability for such molecular markers in three different body fluid compartments in stable cohort of patients. The availability of such data enables calculations to determine the number of patients needed in prospective studies using these markers as outcome measures. (+info)Longitudinal analysis of the relationship between serum insulin-like growth factor-I and radiographic knee osteoarthritis. (7/3222)
OBJECTIVE: To examine the relation between serum insulin-like growth factor I (IGF-I) levels and both incident and progressive radiographic knee osteoarthritis (OA) in the Framingham Osteoarthritis Study. DESIGN: Subjects had bilateral weight-bearing, anterior-posterior knee radiographs performed in 1983-1985 and again in 1992-1993. IGF-I levels were measured from blood specimens obtained in 1988-1989 by a competitive binding radio-immunoassay (RIA) after separation with octadecasilyl-silica cartridges of serum IGF-I from binding proteins. Participants without baseline radiographic OA [Kellgren and Lawrence grades (K&L) = 0-1] were classified as having incident disease if they had K&L > or = 2 grades at follow-up. Progressive OA was defined as an increase in K&L score of > or = 1 in knees with baseline OA (K&L > or = 2). All analyses were knee-based and sex-specific. We examined IGF-I tertiles in relation to the risk of incident and progressive radiographic OA separately, adjusting for age, body mass index (BMI), and baseline K&L score, and used generalized estimating equations to adjust for the correlation between fellow knees. RESULTS: Four hundred and forty-one participants had knee radiographs and serum IGF-I levels measured. No associations were found for serum IGF-I levels and incident [women: OR = 0.9 (0.6-1.7), men OR = 1.2 (0.6-2.6)] or progressive [women OR = 0.9 (0.6-1.6), men OR = 0.9 (0.3-3.0)] radiographic knee OA in either sex. Neither did we observe any association between IGF-I and worsening of individual radiographic features of OA (i.e., osteophyte growth and joint space loss). CONCLUSION: In summary, this longitudinal study did not demonstrate any association of serum IGF-I and incident or progressive radiographic knee OA. Further studies are needed to clarify the role of IGF-I in OA. (+info)1H NMR investigation of changes in the metabolic profile of synovial fluid in bilateral canine osteoarthritis with unilateral joint denervation. (8/3222)
OBJECTIVE: High resolution 1H-nuclear magnetic resonance (NMR) techniques have been used to compare the effects of unilateral knee-joint denervation on the biochemical profiles of synovial fluid in a bilateral canine model of osteoarthritis. METHOD: Paired synovial fluid samples were obtained from seven dogs all of which had previously undergone bilateral anterior cruciate ligament transection, unilateral knee denervation and contralateral sham nerve exposure. All synovial fluid samples were then analyzed using 500 MHz 1H-CPMG spin-echo NMR Spectroscopy to assess differences in endogenous metabolite levels between the paired fluids. RESULTS: The results indicate statistically significant increases in glycerol, hydroxybutyrate, glutamine/glutamate, creatinine/creatine, acetate and N-acetyl-glycoprotein concentrations in synovial fluids from denervated with respect to control knees. Furthermore, significant trends towards elevated lactate, alanine and pyruvate levels in the denervated knee fluids are consistent with our previous findings comparing NMR spectroscopy metabolic profiles of normal and osteoarthritic canine synovial fluids. CONCLUSION: This study lends support to the principle of neurogenic acceleration of OA in that the observed differences in metabolite concentrations found in the denervated knee fluids seem to correlate with metabolic changes resulting from aggravation of the OA process caused by joint denervation. (+info)Osteoarthritis (OA) of the knee is a degenerative joint disease that affects the articular cartilage and subchondral bone in the knee joint. It is characterized by the breakdown and eventual loss of the smooth, cushioning cartilage that covers the ends of bones and allows for easy movement within joints. As the cartilage wears away, the bones rub against each other, causing pain, stiffness, and limited mobility. Osteoarthritis of the knee can also lead to the formation of bone spurs (osteophytes) and cysts in the joint. This condition is most commonly found in older adults, but it can also occur in younger people as a result of injury or overuse. Risk factors include obesity, family history, previous joint injuries, and repetitive stress on the knee joint. Treatment options typically include pain management, physical therapy, and in some cases, surgery.
Osteoarthritis (OA) is a type of joint disease that is characterized by the breakdown and eventual loss of cartilage - the tissue that cushions the ends of bones where they meet in the joints. This breakdown can cause the bones to rub against each other, causing pain, stiffness, and loss of mobility. OA can occur in any joint, but it most commonly affects the hands, knees, hips, and spine. It is often associated with aging and can be caused or worsened by obesity, injury, or overuse.
The medical definition of osteoarthritis is: "a degenerative, non-inflammatory joint disease characterized by the loss of articular cartilage, bone remodeling, and the formation of osteophytes (bone spurs). It is often associated with pain, stiffness, and decreased range of motion in the affected joint."
The knee joint, also known as the tibiofemoral joint, is the largest and one of the most complex joints in the human body. It is a synovial joint that connects the thighbone (femur) to the shinbone (tibia). The patella (kneecap), which is a sesamoid bone, is located in front of the knee joint and helps in the extension of the leg.
The knee joint is made up of three articulations: the femorotibial joint between the femur and tibia, the femoropatellar joint between the femur and patella, and the tibiofibular joint between the tibia and fibula. These articulations are surrounded by a fibrous capsule that encloses the synovial membrane, which secretes synovial fluid to lubricate the joint.
The knee joint is stabilized by several ligaments, including the medial and lateral collateral ligaments, which provide stability to the sides of the joint, and the anterior and posterior cruciate ligaments, which prevent excessive forward and backward movement of the tibia relative to the femur. The menisci, which are C-shaped fibrocartilaginous structures located between the femoral condyles and tibial plateaus, also help to stabilize the joint by absorbing shock and distributing weight evenly across the articular surfaces.
The knee joint allows for flexion, extension, and a small amount of rotation, making it essential for activities such as walking, running, jumping, and sitting.
Osteoarthritis (OA) of the hip is a degenerative joint disease that affects the articular cartilage and subchondral bone of the hip joint. It is characterized by the progressive loss of cartilage, remodeling of bone, osteophyte formation (bone spurs), cysts, and mild to moderate inflammation. The degenerative process can lead to pain, stiffness, limited range of motion, and crepitus (grating or crackling sound) during movement.
In the hip joint, OA typically affects the femoral head and acetabulum. As the articular cartilage wears away, the underlying bone becomes exposed and can lead to bone-on-bone contact, which is painful. The body responds by attempting to repair the damage through remodeling of the subchondral bone and formation of osteophytes. However, these changes can further limit joint mobility and exacerbate symptoms.
Risk factors for OA of the hip include age, obesity, genetics, previous joint injury or surgery, and repetitive stress on the joint. Treatment options may include pain management (such as NSAIDs, physical therapy, and injections), lifestyle modifications (such as weight loss and exercise), and, in severe cases, surgical intervention (such as hip replacement).
In medical terms, the knee is referred to as the largest and one of the most complex joints in the human body. It is a hinge joint that connects the thigh bone (femur) to the shin bones (tibia and fibula), enabling movements like flexion, extension, and a small amount of rotation. The knee also contains several other components such as menisci, ligaments, tendons, and bursae, which provide stability, cushioning, and protection during movement.
Arthroplasty, replacement, knee is a surgical procedure where the damaged or diseased joint surface of the knee is removed and replaced with an artificial joint or prosthesis. The procedure involves resurfacing the worn-out ends of the femur (thigh bone) and tibia (shin bone) with metal components, and the back of the kneecap with a plastic button. This surgery is usually performed to relieve pain and restore function in patients with severe knee osteoarthritis, rheumatoid arthritis, or traumatic injuries that have damaged the joint beyond repair. The goal of knee replacement surgery is to improve mobility, reduce pain, and enhance the quality of life for the patient.
Knee injuries refer to damages or harm caused to the structures surrounding or within the knee joint, which may include the bones (femur, tibia, and patella), cartilage (meniscus and articular cartilage), ligaments (ACL, PCL, MCL, and LCL), tendons (patellar and quadriceps), muscles, bursae, and other soft tissues. These injuries can result from various causes, such as trauma, overuse, degeneration, or sports-related activities. Symptoms may include pain, swelling, stiffness, instability, reduced range of motion, and difficulty walking or bearing weight on the affected knee. Common knee injuries include fractures, dislocations, meniscal tears, ligament sprains or ruptures, and tendonitis. Proper diagnosis and treatment are crucial to ensure optimal recovery and prevent long-term complications.
A knee prosthesis, also known as a knee replacement or artificial knee joint, is a medical device used to replace the damaged or diseased weight-bearing surfaces of the knee joint. It typically consists of three components: the femoral component (made of metal) that fits over the end of the thighbone (femur), the tibial component (often made of metal and plastic) that fits into the top of the shinbone (tibia), and a patellar component (usually made of plastic) that replaces the damaged surface of the kneecap.
The primary goal of knee prosthesis is to relieve pain, restore function, and improve quality of life for individuals with advanced knee joint damage due to conditions such as osteoarthritis, rheumatoid arthritis, or traumatic injuries. The procedure to implant a knee prosthesis is called knee replacement surgery or total knee arthroplasty (TKA).
Articular cartilage is the smooth, white tissue that covers the ends of bones where they come together to form joints. It provides a cushion between bones and allows for smooth movement by reducing friction. Articular cartilage also absorbs shock and distributes loads evenly across the joint, protecting the bones from damage. It is avascular, meaning it does not have its own blood supply, and relies on the surrounding synovial fluid for nutrients. Over time, articular cartilage can wear down or become damaged due to injury or disease, leading to conditions such as osteoarthritis.
The menisci are crescent-shaped fibrocartilaginous structures located in the knee joint. There are two menisci in each knee: the medial meniscus and the lateral meniscus. The tibial menisci, also known as the medial and lateral menisci, are named according to their location in the knee joint. They lie on the top surface of the tibia (shin bone) and provide shock absorption, stability, and lubrication to the knee joint.
The tibial menisci have a complex shape, with a wider outer portion called the peripheral rim and a narrower inner portion called the central portion or root attachment. The menisci are attached to the bones of the knee joint by ligaments and have a rich blood supply in their outer portions, which helps in healing after injury. However, the inner two-thirds of the menisci have a poor blood supply, making them more prone to degeneration and less likely to heal after injury.
Damage to the tibial menisci can occur due to trauma or degenerative changes, leading to symptoms such as pain, swelling, stiffness, and limited mobility of the knee joint. Treatment for meniscal injuries may include physical therapy, bracing, or surgery, depending on the severity and location of the injury.
Arthralgia is a medical term that refers to pain in the joints. It does not involve inflammation, which would be referred to as arthritis. The pain can range from mild to severe and may occur in one or multiple joints. Arthralgia can have various causes, including injuries, infections, degenerative conditions, or systemic diseases. In some cases, the underlying cause of arthralgia remains unknown. Treatment typically focuses on managing the pain and addressing the underlying condition if it can be identified.
Osteoarthritis of the spine, also known as spondylosis, is a degenerative joint disease that affects the spine. It is characterized by the breakdown and eventual loss of cartilage in the joints of the spine, which can lead to pain, stiffness, and decreased mobility. The condition most commonly affects the joints in the lower back (lumbar) and neck (cervical) regions of the spine.
The symptoms of osteoarthritis of the spine can vary widely, but may include:
* Pain and stiffness in the neck or back, especially after prolonged periods of inactivity or overuse
* Numbness, tingling, or weakness in the arms or legs, due to nerve compression
* Decreased range of motion and flexibility in the spine
* Popping, cracking, or grinding sounds in the spine with movement
* In severe cases, loss of bladder or bowel control.
The diagnosis of osteoarthritis of the spine is typically made through a combination of physical exam, medical history, and imaging studies such as X-rays, MRI, or CT scan. Treatment options may include pain medication, physical therapy, exercise, and in some cases, surgery.
Articular Range of Motion (AROM) is a term used in physiotherapy and orthopedics to describe the amount of movement available in a joint, measured in degrees of a circle. It refers to the range through which synovial joints can actively move without causing pain or injury. AROM is assessed by measuring the degree of motion achieved by active muscle contraction, as opposed to passive range of motion (PROM), where the movement is generated by an external force.
Assessment of AROM is important in evaluating a patient's functional ability and progress, planning treatment interventions, and determining return to normal activities or sports participation. It is also used to identify any restrictions in joint mobility that may be due to injury, disease, or surgery, and to monitor the effectiveness of rehabilitation programs.
Pain measurement, in a medical context, refers to the quantification or evaluation of the intensity and/or unpleasantness of a patient's subjective pain experience. This is typically accomplished through the use of standardized self-report measures such as numerical rating scales (NRS), visual analog scales (VAS), or categorical scales (mild, moderate, severe). In some cases, physiological measures like heart rate, blood pressure, and facial expressions may also be used to supplement self-reported pain ratings. The goal of pain measurement is to help healthcare providers better understand the nature and severity of a patient's pain in order to develop an effective treatment plan.
Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage. It is a complex phenomenon that can result from various stimuli, such as thermal, mechanical, or chemical irritation, and it can be acute or chronic. The perception of pain involves the activation of specialized nerve cells called nociceptors, which transmit signals to the brain via the spinal cord. These signals are then processed in different regions of the brain, leading to the conscious experience of pain. It's important to note that pain is a highly individual and subjective experience, and its perception can vary widely among individuals.
An osteophyte, also known as a bone spur, is a bony projection that forms along the margins of joints, often as a result of degenerative changes in the cartilage and underlying bone. These changes are most commonly seen in conditions such as osteoarthritis, where the protective cartilage that cushions the ends of bones breaks down, leading to inflammation, pain, and reduced mobility.
Osteophytes can develop in any joint in the body, but they are most commonly found in the spine, hips, knees, and hands. They may vary in size from small bumps to large, irregular growths that can restrict joint movement and cause discomfort or pain. In some cases, osteophytes may also compress nearby nerves, leading to symptoms such as numbness, tingling, or weakness in the affected limb.
While osteophytes are often considered a sign of aging or joint degeneration, they can also be caused by other conditions that put excessive stress on the joints, such as injury, infection, or inflammatory arthritis. Treatment for osteophytes typically involves addressing the underlying cause of joint damage, along with pain management strategies such as physical therapy, medication, or in some cases, surgery.
The tibia, also known as the shin bone, is the larger of the two bones in the lower leg and part of the knee joint. It supports most of the body's weight and is a major insertion point for muscles that flex the foot and bend the leg. The tibia articulates with the femur at the knee joint and with the fibula and talus bone at the ankle joint. Injuries to the tibia, such as fractures, are common in sports and other activities that put stress on the lower leg.
A hand joint, also known as an articulation, is the location at which two or more bones connect. Specifically, in the context of the hand, there are several types of joints:
1. **Metacarpophalangeal (MCP) Joints:** These are the joints located between the metacarpal bones of the hand and the proximal phalanges of the fingers. The MCP joints allow for flexion, extension, abduction, adduction, and circumduction movements.
2. **Proximal Interphalangeal (PIP) Joints:** These are the joints located between the proximal and middle phalanges of the fingers. The PIP joints allow for flexion, extension, and a limited amount of abduction and adduction movements.
3. **Distal Interphalangeal (DIP) Joints:** These are the joints located between the middle and distal phalanges of the fingers. The DIP joints mainly allow for flexion and extension movements.
4. **Carpometacarpal (CMC) Joints:** These are the joints located between the carpal bones of the wrist and the metacarpal bones of the hand. The CMC joints, particularly the first CMC joint at the base of the thumb, allow for a wide range of movements, including flexion, extension, abduction, adduction, and opposition (the ability to touch the tip of the thumb to each of the other fingers).
These hand joints are supported by various structures such as ligaments, tendons, muscles, and cartilage, which provide stability, enable movement, and absorb shock during daily activities.
The Anterior Cruciate Ligament (ACL) is a major stabilizing ligament in the knee. It is one of the four strong bands of tissue that connect the bones of the knee joint together. The ACL runs diagonally through the middle of the knee and helps to control the back and forth motion of the knee, as well as provide stability to the knee joint. Injuries to the ACL often occur during sports or physical activities that involve sudden stops, changes in direction, or awkward landings.
The patella, also known as the kneecap, is a sesamoid bone located at the front of the knee joint. It is embedded in the tendon of the quadriceps muscle and serves to protect the knee joint and increase the leverage of the extensor mechanism, allowing for greater extension force of the lower leg. The patella moves within a groove on the femur called the trochlea during flexion and extension of the knee.
Synovial fluid is a viscous, clear, and straw-colored fluid found in the cavities of synovial joints, bursae, and tendon sheaths. It is produced by the synovial membrane, which lines the inner surface of the capsule surrounding these structures.
The primary function of synovial fluid is to reduce friction between articulating surfaces, providing lubrication for smooth and painless movement. It also acts as a shock absorber, protecting the joints from external forces during physical activities. Synovial fluid contains nutrients that nourish the articular cartilage, hyaluronic acid, which provides its viscoelastic properties, and lubricin, a protein responsible for boundary lubrication.
Abnormalities in synovial fluid composition or volume can indicate joint-related disorders, such as osteoarthritis, rheumatoid arthritis, gout, infection, or trauma. Analysis of synovial fluid is often used diagnostically to determine the underlying cause of joint pain, inflammation, or dysfunction.
"Weight-bearing" is a term used in the medical field to describe the ability of a body part or limb to support the weight or pressure exerted upon it, typically while standing, walking, or performing other physical activities. In a clinical setting, healthcare professionals often use the term "weight-bearing exercise" to refer to physical activities that involve supporting one's own body weight, such as walking, jogging, or climbing stairs. These exercises can help improve bone density, muscle strength, and overall physical function, particularly in individuals with conditions affecting the bones, joints, or muscles.
In addition, "weight-bearing" is also used to describe the positioning of a body part during medical imaging studies, such as X-rays or MRIs. For example, a weight-bearing X-ray of the foot or ankle involves taking an image while the patient stands on the affected limb, allowing healthcare providers to assess any alignment or stability issues that may not be apparent in a non-weight-bearing position.
Intra-articular injections refer to the administration of medication directly into a joint space. This route of administration is used for treating various joint conditions such as inflammation, pain, and arthritis. Commonly injected medications include corticosteroids, local anesthetics, and viscosupplementation agents. The procedure is usually performed using imaging guidance, like ultrasound or fluoroscopy, to ensure accurate placement of the medication within the joint.
Chondrocytes are the specialized cells that produce and maintain the extracellular matrix of cartilage tissue. They are responsible for synthesizing and secreting the collagen fibers, proteoglycans, and other components that give cartilage its unique properties, such as elasticity, resiliency, and resistance to compression. Chondrocytes are located within lacunae, or small cavities, in the cartilage matrix, and they receive nutrients and oxygen through diffusion from the surrounding tissue fluid. They are capable of adapting to changes in mechanical stress by modulating the production and organization of the extracellular matrix, which allows cartilage to withstand various loads and maintain its structural integrity. Chondrocytes play a crucial role in the development, maintenance, and repair of cartilaginous tissues throughout the body, including articular cartilage, costal cartilage, and growth plate cartilage.
The synovial membrane, also known as the synovium, is the soft tissue that lines the inner surface of the capsule of a synovial joint, which is a type of joint that allows for smooth movement between bones. This membrane secretes synovial fluid, a viscous substance that lubricates and nourishes the cartilage and helps to reduce friction within the joint during movement.
The synovial membrane has a highly specialized structure, consisting of two layers: the intima and the subintima. The intima is a thin layer of cells that are in direct contact with the synovial fluid, while the subintima is a more fibrous layer that contains blood vessels and nerves.
The main function of the synovial membrane is to produce and regulate the production of synovial fluid, as well as to provide nutrients to the articular cartilage. It also plays a role in the immune response within the joint, helping to protect against infection and inflammation. However, abnormalities in the synovial membrane can lead to conditions such as rheumatoid arthritis, where the membrane becomes inflamed and produces excess synovial fluid, leading to pain, swelling, and joint damage.
Bone malalignment is a term used to describe the abnormal alignment or positioning of bones in relation to each other. This condition can occur as a result of injury, deformity, surgery, or disease processes that affect the bones and joints. Bone malalignment can cause pain, stiffness, limited mobility, and an increased risk of further injury. In some cases, bone malalignment may require treatment such as bracing, physical therapy, or surgery to correct the alignment and improve function.
A finger joint, also known as an articulation, is the point where two bones in a finger connect and allow for movement. The majority of finger joints are classified as hinge joints, permitting flexion and extension movements. These joints consist of several components:
1. Articular cartilage: Smooth tissue that covers the ends of the bones, enabling smooth movement and protecting the bones from friction.
2. Joint capsule: A fibrous sac enclosing the joint, providing stability and producing synovial fluid for lubrication.
3. Synovial membrane: Lines the inner surface of the joint capsule and produces synovial fluid to lubricate the joint.
4. Volar plate (palmar ligament): A strong band of tissue located on the palm side of the joint, preventing excessive extension and maintaining alignment.
5. Collateral ligaments: Two bands of tissue located on each side of the joint, providing lateral stability and limiting radial and ulnar deviation.
6. Flexor tendons: Tendons that attach to the bones on the palmar side of the finger joints, facilitating flexion movements.
7. Extensor tendons: Tendons that attach to the bones on the dorsal side of the finger joints, enabling extension movements.
Finger joints are essential for hand function and enable activities such as grasping, holding, writing, and manipulating objects.
The hip joint, also known as the coxal joint, is a ball-and-socket type synovial joint that connects the femur (thigh bone) to the pelvis. The "ball" is the head of the femur, while the "socket" is the acetabulum, a concave surface on the pelvic bone.
The hip joint is surrounded by a strong fibrous capsule and is reinforced by several ligaments, including the iliofemoral, ischiofemoral, and pubofemoral ligaments. The joint allows for flexion, extension, abduction, adduction, medial and lateral rotation, and circumduction movements, making it one of the most mobile joints in the body.
The hip joint is also supported by various muscles, including the gluteus maximus, gluteus medius, gluteus minimus, iliopsoas, and other hip flexors and extensors. These muscles provide stability and strength to the joint, allowing for weight-bearing activities such as walking, running, and jumping.
A Severity of Illness Index is a measurement tool used in healthcare to assess the severity of a patient's condition and the risk of mortality or other adverse outcomes. These indices typically take into account various physiological and clinical variables, such as vital signs, laboratory values, and co-morbidities, to generate a score that reflects the patient's overall illness severity.
Examples of Severity of Illness Indices include the Acute Physiology and Chronic Health Evaluation (APACHE) system, the Simplified Acute Physiology Score (SAPS), and the Mortality Probability Model (MPM). These indices are often used in critical care settings to guide clinical decision-making, inform prognosis, and compare outcomes across different patient populations.
It is important to note that while these indices can provide valuable information about a patient's condition, they should not be used as the sole basis for clinical decision-making. Rather, they should be considered in conjunction with other factors, such as the patient's overall clinical presentation, treatment preferences, and goals of care.
Biomechanics is the application of mechanical laws to living structures and systems, particularly in the field of medicine and healthcare. A biomechanical phenomenon refers to a observable event or occurrence that involves the interaction of biological tissues or systems with mechanical forces. These phenomena can be studied at various levels, from the molecular and cellular level to the tissue, organ, and whole-body level.
Examples of biomechanical phenomena include:
1. The way that bones and muscles work together to produce movement (known as joint kinematics).
2. The mechanical behavior of biological tissues such as bone, cartilage, tendons, and ligaments under various loads and stresses.
3. The response of cells and tissues to mechanical stimuli, such as the way that bone tissue adapts to changes in loading conditions (known as Wolff's law).
4. The biomechanics of injury and disease processes, such as the mechanisms of joint injury or the development of osteoarthritis.
5. The use of mechanical devices and interventions to treat medical conditions, such as orthopedic implants or assistive devices for mobility impairments.
Understanding biomechanical phenomena is essential for developing effective treatments and prevention strategies for a wide range of medical conditions, from musculoskeletal injuries to neurological disorders.
Joint instability is a condition characterized by the loss of normal joint function and increased risk of joint injury due to impaired integrity of the supporting structures, such as ligaments, muscles, or cartilage. This can result in excessive movement or laxity within the joint, leading to decreased stability and increased susceptibility to dislocations or subluxations. Joint instability may cause pain, swelling, and limited range of motion, and it can significantly impact a person's mobility and quality of life. It is often caused by trauma, degenerative conditions, or congenital abnormalities and may require medical intervention, such as physical therapy, bracing, or surgery, to restore joint stability.
Arthroscopy is a minimally invasive surgical procedure where an orthopedic surgeon uses an arthroscope (a thin tube with a light and camera on the end) to diagnose and treat problems inside a joint. The surgeon makes a small incision, inserts the arthroscope into the joint, and then uses the attached camera to view the inside of the joint on a monitor. They can then insert other small instruments through additional incisions to repair or remove damaged tissue.
Arthroscopy is most commonly used for joints such as the knee, shoulder, hip, ankle, and wrist. It offers several advantages over traditional open surgery, including smaller incisions, less pain and bleeding, faster recovery time, and reduced risk of infection. The procedure can be used to diagnose and treat a wide range of conditions, including torn ligaments or cartilage, inflamed synovial tissue, loose bone or cartilage fragments, and joint damage caused by arthritis.
Treatment outcome is a term used to describe the result or effect of medical treatment on a patient's health status. It can be measured in various ways, such as through symptoms improvement, disease remission, reduced disability, improved quality of life, or survival rates. The treatment outcome helps healthcare providers evaluate the effectiveness of a particular treatment plan and make informed decisions about future care. It is also used in clinical research to compare the efficacy of different treatments and improve patient care.
The term "stifle" is commonly used in veterinary medicine to refer to the joint in the leg of animals, specifically the knee joint in quadrupeds such as dogs and horses. In human anatomy, this joint is called the patellofemoral joint or knee joint. The stifle is a complex joint made up of several bones, including the femur, tibia, and patella (kneecap), as well as various ligaments, tendons, and cartilage that provide stability and support. Injuries or diseases affecting the stifle can cause lameness, pain, and decreased mobility in animals.
Gait is a medical term used to describe the pattern of movement of the limbs during walking or running. It includes the manner or style of walking, including factors such as rhythm, speed, and step length. A person's gait can provide important clues about their physical health and neurological function, and abnormalities in gait may indicate the presence of underlying medical conditions, such as neuromuscular disorders, orthopedic problems, or injuries.
A typical human gait cycle involves two main phases: the stance phase, during which the foot is in contact with the ground, and the swing phase, during which the foot is lifted and moved forward in preparation for the next step. The gait cycle can be further broken down into several sub-phases, including heel strike, foot flat, midstance, heel off, and toe off.
Gait analysis is a specialized field of study that involves observing and measuring a person's gait pattern using various techniques, such as video recordings, force plates, and motion capture systems. This information can be used to diagnose and treat gait abnormalities, improve mobility and function, and prevent injuries.
Rheumatoid arthritis (RA) is a systemic autoimmune disease that primarily affects the joints. It is characterized by persistent inflammation, synovial hyperplasia, and subsequent damage to the articular cartilage and bone. The immune system mistakenly attacks the body's own tissues, specifically targeting the synovial membrane lining the joint capsule. This results in swelling, pain, warmth, and stiffness in affected joints, often most severely in the hands and feet.
RA can also have extra-articular manifestations, affecting other organs such as the lungs, heart, skin, eyes, and blood vessels. The exact cause of RA remains unknown, but it is believed to involve a complex interplay between genetic susceptibility and environmental triggers. Early diagnosis and treatment are crucial in managing rheumatoid arthritis to prevent joint damage, disability, and systemic complications.
Arthrography is a medical imaging technique used to diagnose problems within joints. It involves the injection of a contrast agent, such as a radiopaque dye or air, into the joint space, followed by the use of fluoroscopy or X-ray imaging to visualize the internal structures of the joint. This can help to identify injuries, tears, or other abnormalities in the cartilage, ligaments, tendons, or bones within the joint.
The procedure is typically performed on an outpatient basis and may be used to diagnose conditions such as shoulder dislocations, rotator cuff tears, meniscal tears in the knee, or hip labral injuries. It is a relatively safe and minimally invasive procedure, although there may be some temporary discomfort or swelling at the injection site. Patients are usually advised to avoid strenuous activity for a day or two following the procedure to allow the contrast agent to fully dissipate from the joint.
Synovitis is a medical condition characterized by inflammation of the synovial membrane, which is the soft tissue that lines the inner surface of joint capsules and tendon sheaths. The synovial membrane produces synovial fluid, which lubricates the joint and allows for smooth movement.
Inflammation of the synovial membrane can cause it to thicken, redden, and become painful and swollen. This can lead to stiffness, limited mobility, and discomfort in the affected joint or tendon sheath. Synovitis may occur as a result of injury, overuse, infection, or autoimmune diseases such as rheumatoid arthritis.
If left untreated, synovitis can cause irreversible damage to the joint and surrounding tissues, including cartilage loss and bone erosion. Treatment typically involves a combination of medications, physical therapy, and lifestyle modifications to reduce inflammation and manage pain.
Viscosupplementation is a medical procedure where a thick, gel-like substance called hyaluronic acid is injected into a joint, usually the knee. The goal of this treatment is to supplement or replace the viscous properties of the synovial fluid within the joint that has become thin and less effective due to aging, arthritis, or injury.
Hyaluronic acid is a naturally occurring substance in the body, particularly in the synovial fluid, which acts as a lubricant and shock absorber for the joints. By injecting additional hyaluronic acid into the affected joint, viscosupplementation aims to improve joint mobility, reduce pain, and protect the cartilage from further damage.
This procedure is often considered when other treatments, such as physical therapy, pain medications, or corticosteroid injections, have not provided sufficient relief for patients with osteoarthritis or other joint-related conditions. Viscosupplementation can be a short-term solution to alleviate symptoms and improve the quality of life for those suffering from joint pain and stiffness.
Hyaluronic acid is a glycosaminoglycan, a type of complex carbohydrate, that is naturally found in the human body. It is most abundant in the extracellular matrix of soft connective tissues, including the skin, eyes, and joints. Hyaluronic acid is known for its remarkable capacity to retain water, which helps maintain tissue hydration, lubrication, and elasticity. Its functions include providing structural support, promoting wound healing, and regulating cell growth and differentiation. In the medical field, hyaluronic acid is often used in various forms as a therapeutic agent for conditions like osteoarthritis, dry eye syndrome, and skin rejuvenation.
Knee dislocation is a serious and uncommon orthopedic injury that occurs when the bones that form the knee joint (femur, tibia, and patella) are forced out of their normal position due to extreme trauma or force. This injury often requires immediate medical attention and reduction (repositioning) by a healthcare professional. If left untreated, it can lead to serious complications such as compartment syndrome, nerve damage, and long-term joint instability. It's important to note that knee dislocation is different from a kneecap (patellar) dislocation, which involves the patella sliding out of its groove in the femur.
Hip arthroplasty, also known as hip replacement surgery, is a medical procedure where the damaged or diseased joint surfaces of the hip are removed and replaced with artificial components. These components typically include a metal or ceramic ball that replaces the head of the femur (thigh bone), and a polyethylene or ceramic socket that replaces the acetabulum (hip socket) in the pelvis.
The goal of hip arthroplasty is to relieve pain, improve joint mobility, and restore function to the hip joint. This procedure is commonly performed in patients with advanced osteoarthritis, rheumatoid arthritis, hip fractures, or other conditions that cause significant damage to the hip joint.
There are several types of hip replacement surgeries, including traditional total hip arthroplasty, partial (hemi) hip arthroplasty, and resurfacing hip arthroplasty. The choice of procedure depends on various factors, such as the patient's age, activity level, overall health, and the extent of joint damage.
After surgery, patients typically require rehabilitation to regain strength, mobility, and function in the affected hip. With proper care and follow-up, most patients can expect significant pain relief and improved quality of life following hip arthroplasty.
The Quadriceps muscle, also known as the Quadriceps Femoris, is a large muscle group located in the front of the thigh. It consists of four individual muscles - the Rectus Femoris, Vastus Lateralis, Vastus Intermedius, and Vastus Medialis. These muscles work together to extend the leg at the knee joint and flex the thigh at the hip joint. The Quadriceps muscle is crucial for activities such as walking, running, jumping, and kicking.
The medial collateral ligament (MCL) of the knee is a band-like structure located on the inner side of the knee joint. It connects the end of the femur (thighbone) to the top of the tibia (shinbone) and helps stabilize the knee by controlling side-to-side movement and preventing excessive separation of the bones. The MCL provides resistance to valgus force, which is a pushing or pulling force that attempts to push the bones apart in a direction away from the midline of the body. MCL injuries often occur due to direct impact to the outer knee or sudden changes in direction that strain the ligament.
Viscosupplements are a type of medication that contain a gel-like substance called hyaluronic acid, which is naturally found in the synovial fluid of joints. This fluid acts as a lubricant and shock absorber for the joints, allowing smooth movement and protecting them from wear and tear.
In osteoarthritis, the synovial fluid may become less viscous and contain lower levels of hyaluronic acid, leading to pain, stiffness, and reduced mobility in the affected joint. Viscosupplementation involves injecting a preparation of high molecular weight hyaluronic acid into the joint space to restore its normal viscoelastic properties and provide symptomatic relief from osteoarthritis.
Viscosupplements are typically administered through a series of injections, usually given once a week for 3-5 weeks, depending on the specific product used. They may help reduce pain, improve joint function, and increase mobility in people with osteoarthritis, particularly in the knee joint. However, their effectiveness varies from person to person, and they are not recommended for everyone with osteoarthritis. It is important to consult a healthcare provider to determine if viscosupplementation is appropriate for an individual's specific condition.
Joint diseases is a broad term that refers to various conditions affecting the joints, including but not limited to:
1. Osteoarthritis (OA): A degenerative joint disease characterized by the breakdown of cartilage and underlying bone, leading to pain, stiffness, and potential loss of function.
2. Rheumatoid Arthritis (RA): An autoimmune disorder causing inflammation in the synovial membrane lining the joints, resulting in swelling, pain, and joint damage if left untreated.
3. Infectious Arthritis: Joint inflammation caused by bacterial, viral, or fungal infections that spread through the bloodstream or directly enter the joint space.
4. Gout: A type of arthritis resulting from the buildup of uric acid crystals in the joints, typically affecting the big toe and characterized by sudden attacks of severe pain, redness, and swelling.
5. Psoriatic Arthritis (PsA): An inflammatory joint disease associated with psoriasis, causing symptoms such as pain, stiffness, and swelling in the joints and surrounding tissues.
6. Juvenile Idiopathic Arthritis (JIA): A group of chronic arthritis conditions affecting children, characterized by joint inflammation, pain, and stiffness.
7. Ankylosing Spondylitis: A form of arthritis primarily affecting the spine, causing inflammation, pain, and potential fusion of spinal vertebrae.
8. Bursitis: Inflammation of the fluid-filled sacs (bursae) that cushion joints, leading to pain and swelling.
9. Tendinitis: Inflammation or degeneration of tendons, which connect muscles to bones, often resulting in pain and stiffness near joints.
These conditions can impact the function and mobility of affected joints, causing discomfort and limiting daily activities. Proper diagnosis and treatment are essential for managing joint diseases and preserving joint health.
