TY - JOUR. T1 - The differential effects of gender, anthropometry, and prior hormonal state on frontal plane knee joint stiffness. AU - Cammarata, Martha L.. AU - Dhaher, Yasin Y.. PY - 2008/8/1. Y1 - 2008/8/1. N2 - Background: Gender differences in passive frontal plane knee stiffness may contribute to the increased anterior cruciate ligament injury rate in females. Gender-based stiffness differences have been attributed to anthropometric variations, but little data exist describing this relationship. Furthermore, sex hormone levels appear to influence joint stiffness, but the differential effects of instantaneous and prior hormonal concentrations remain unknown. This study sought to explore the effect of gender, prior hormonal status, and anthropometry on passive frontal plane knee joint stiffness. Methods: Twelve males and 31 females participated. Females were grouped by hormonal contraceptive use (non users [n = 11], monophasic contraceptive users [n = 11], and triphasic contraceptive users ...

The external knee adduction moment during gait has previously been associated with knee osteoarthritis, and although it has been shown to be greater following anterior cruciate ligament (ACL) reconstruction surgery compared to a control group, it has not been compared between different graft types. Given that the incidence of radiographic knee osteoarthritis appears to be greater following patellar tendon compared to hamstring tendon ACL reconstruction, this study tested the hypothesis that the knee adduction moment would also be increased following patellar tendon ACL reconstruction.In 48 male participants (16 patellar tendon graft, 16 hamstring graft and 16 controls), the external knee adduction moment was measured during level walking in a gait laboratory at mean of 10 months after surgery.There was no difference in the knee adduction moment between the hamstring and patellar tendon groups, and both patient groups had a significantly reduced knee adduction moment compared to the control ...

AU - Hamai, Satoshi. AU - Robb, William J.. AU - Banks, Scott A.. PY - 2012/1/1. Y1 - 2012/1/1. N2 - Orthopedic surgeons and their patients continue to seek better functional outcomes after total knee arthroplasty. The bicruciate substituting (BCS) total knee arthroplasty design has been introduced to achieve more natural knee mechanics. The purpose of this study was to characterize kinematics in knees with BCS arthroplasty during deep flexion and stair activities using fluoroscopy and model-image registration. In 20 patients with 25 BCS knees, we observed average implant flexion of 128° during kneeling and consistent posterior condylar translations with knee flexion. Tibial rotations were qualitatively similar to those observed in the arthritic natural knee. Knee kinematics with BCS arthroplasty were ...

Unicompartmental knee replacement is a minimally invasive surgery in which only the damaged compartment of the knee is replaced with an implant. It is also called a partial knee replacement. The knee can be divided into three compartments: patellofemoral, the compartment in front of the knee between the knee cap and thigh bone, medial compartment, on the inside portion of the knee, and lateral compartment which is the area on the outside portion of the knee joint.. Traditionally, total knee replacement was commonly indicated for severe osteoarthritis of the knee. In total knee replacement all worn out or damaged surfaces of the knee joint are removed and replaced with new artificial parts. Partial knee replacement is a surgical option if your arthritis is confined to a single compartment of your knee.. Disease Overview. Arthritis is inflammation of a joint causing pain, swelling (inflammation), and stiffness.. Osteoarthritis is the most common form of knee arthritis in which the joint cartilage ...

Objectives: Knee is the largest weight bearing joint in the body and thereby is affected by diseases such as osteoarthritis more frequently. The aim of this study was to evaluate the effect of a 4 week physiotherapy exercise program, designed to improve quadriceps muscle strength and girth, and to observe its effect on knee pain and activities of daily life through a pre and post exercise analysis in patients with knee joint osteoarthritis (OA).. Methods: Thirty patients diagnosed with knee joint osteoarthritis irrespective of gender, over the age of 45 and less than 75 years were recruited for the study. Initially knee joint pain severity was assessed using the VAS (visual analogue scales) and WOMAC questionnaire was used to assess the activities of daily living. The thigh circumference was measured in centimeters. Data was analyzed by SPSS 20.. Results: Mean age of osteoarthritis patients was 54 years. There was a statistically significant, reduction in knee pain (p=0.001), improvement of ...

The aim of this study was to investigate the kinetic characteristics of compensatory backward descending movement performed by patients with osteoarthritis of the knee. Using a three-dimensional motion analysis system, we investigated lower extremity joint angles, joint moments, joint force of the support leg in forward and backward descending movements on stairs, and joint force of the leading leg at landing in 7 female patients with osteoarthritis of the knee. Compared with the forward descending movement, knee joint angle, joint moment and joint force of the support leg all decreased in the backward descending movement. Joint force of the leading leg at landing was also reduced in the backward descending movement. In addition, we confirmed that the center of body mass was mainly controlled by the knee and ankle joints in the forward descending movement, and by the hip joint in the backward descending movement. Since it has been reported that knee flexion angle and extensor muscle strength are

Background In a typical osteoarthritic knee with varus deformity, distal femoral resection based off the worn medial femoral condyle may result in an elevated joint line. In a setting of fixed flexion contracture, the surgeon may choose to resect additional distal femur to obtain extension, thus purposefully raising the joint line. However, the biomechanical effect of raising the joint line is not well recognized.. Questions/purposes (1) What is the effect of the level of the medial joint line (restored versus raised) on coronal plane stability of a TKA? (2) Does coronal alignment technique (mechanical axis versus kinematic technique) affect coronal plane stability of the knee? (3) Can the effect of medial joint-line elevation on coronal plane laxity be predicted by an analytical model?. Methods A TKA prosthesis was implanted in 10 fresh frozen nonarthritic cadaveric knees with restoration of the medial joint line at its original level (TKA0). Coronal plane stability was measured at 0°, 30°, ...

Background: It is not well understood why one in five patients report poor outcomes following knee arthroplasty. This study evaluated changes in knee biomechanics, and perceived pain among patients reporting either a good or a poor outcome in knee-related quality of life after total knee arthroplasty.. Methods: Twenty-eight patients (mean age 66 (SD 7) years) were included in this prospective study. Within one month of knee arthroplasty and one year after surgery, patients underwent three-dimensional (3D) gait analysis, completed the Knee Injury and Osteoarthritis Outcome Score (KOOS), and rated perceived pain using a visual analogue scale. A good outcome was defined as a change greater than the minimally detectable change in the KOOS knee-related quality of life, and a poor outcome was defined as change below the minimally detectable change. Nineteen patients (68%) were classified as having a good outcome. Groups were analyzed separately and knee biomechanics were compared using a two-way ...

Knee Arthroscopy is a common surgical procedure performed using an arthroscope, a viewing instrument, to look into the knee joint to diagnose or treat a knee problem. It is a relatively safe procedure and a majority of the patients discharge from the hospital on the same day of surgery.. The knee joint is one of the most complex joints of the body. The lower end of the thighbone (femur) meets the upper end of the shinbone (tibia) at the knee joint. A small bone called the patella (kneecap) rests on a groove on the front side of the femoral end. A bone of the lower leg (fibula) forms a joint with the shinbone.. To allow smooth and painless motion of the knee joint, articular surfaces of these bones are covered with a shiny white slippery articular cartilage. Two C-shaped cartilaginous menisci are present in between the femoral end and the tibial end.. Menisci act as shock absorbers providing cushion to the joints. Menisci also play an important role in providing stability and load bearing to the ...

A lot of people complain of chronic knee pain which can be due to long term swelling, pain, sensitivity in the knees. Such long term knee injuries can be caused due to various conditions and for each of these conditions, a specific treatment is done. At times, you can be advised to use an adjustable knee brace as a part of treatment.. Not everyone with a chronic knee pain will have same kind of experiences.. You should not confuse chronic knee pain with a temporary knee pain because chronic knee pain does not go away so easily unless it is treated properly and there can be multiple conditions due to which the knee is suffering whereas a temporary knee pain can be caused due to an accident or some injury.. There are several factors which can worsen a long term knee injury:. ...

Knees may make crunching clamors and they might be incidentally be stuck in a position wherein an individual might be not able to fix them totally. Pain in knees could be joined by redness and expanding around the joint. Office conditions are regularly unpleasant for joints, and may prompt pain in knees or back. Being in an office domain and sitting for beyond what an hour at a time could cause knee joint pain because of latency, while an awful stance may put weight on the kneecap. Additionally, if office furniture is not structured ergonomically or one does not utilize furniture that has an appropriate position, tallness or arrangement, it might prompt pain in knees and joints. Knee joint pain can now and again sway ordinary exercises, such as tying our shoelaces. One of the main sources of knee joint pain is osteoarthritis, which is described by breakdown of an individuals knee cartridge..

No, and you should be skeptical of any doctor or advertisement telling you otherwise. Those advertisements are designed to make a sale, rather than educate and enlighten consumers.. Normal human knee movement consists of gliding, rotation, sliding, and other complex movements. A synthetic joint can only approximate the intricacy and complexity of the knee joint that you were born with. No artificial knee joint, regardless of manufacturers advertising claims, or surgeon claims, has ever duplicated the complexity and intricate movements of the natural human knee.. The human knee joint has major ligaments and other soft tissue supports; these have fine nerve endings that send sensory, positional, and perceptual feedback to the brain from the knee. An artificial knee is simply metal and plastic. For severely diseased knees, modern total knee replacements provide excellent pain relief and function, but they are never a perfect substitute for the real thing.. ...

In order to identify abnormal or pathological motions associated with clinically relevant questions such as injury mechanisms or factors leading to joint degeneration, it is essential to determine the range of normal tibiofemoral motion of the healthy knee. In this study we measured in vivo 3D tibiofemoral motion of the knee during gait and characterized the nonsagittal plane rotations and translations in a group of six healthy young adults. The subjects were instrumented with markers placed on intracortical pins inserted into the tibia and femur as well as marker clusters placed on the skin of the thigh and shank. The secondary rotations and translation excursions of the knee were much smaller than those derived from skin markers and previously described in the literature. Also, for a given knee flexion angle, multiple combinations of transverse and frontal plane knee translation or rotation positions were found. This represents normal knee joint motions and ensemble averaging of gait data may ...

The symptoms are usually needed before knee problems can be treated. You can experience pain and swelling if you have a serious knee injury, with difficulty bending it or bearing your weight. The swelling may be coming and going, and if you get involved in any activity involving the use of the knee, the condition may be severe. Ligament injury may be what you are suffering from if you have the feeling that the knee is unstable or is giving away, and with a popping or a grinding, and an inability to bend it, it means that you have a cartilage tear. You may need knee replacement if you are experiencing knee problems like torn cartilage, arthritis, tendonitis or severe or chronic knee pain.. ...

Partial lateral knee replacement is a surgery to replace only the lateral part of your damaged knee. It is also called unicompartmental knee replacement. The knee is one of the largest and complex joints in your body. The joint is connected to your thigh bones and bones of the lower leg by various ligaments. The knee joint is made of three compartments. The lateral, the medial and the patellofemoral compartment. The outside part of the knee is the lateral compartment. It consists of a Lateral Collateral Ligament (LCL). ...

The physician grasps the patients heel with one hand and the knee with the other hand. The physicians thumb is at the lateral joint line, and fingers are at the medial joint line. The physician then flexes the patients knee maximally. To test the lateral meniscus, the tibia is rotated internally, and the knee is extended from maximal flexion to about 90 degrees; added compression to the lateral meniscus can be produced by applying valgus stress across the knee joint while the knee is being extended. To test the medial meniscus, the tibia is rotated externally, and the knee is extended from maximal flexion to about 90 degrees; added compression to the medial meniscus can be produced by placing varus stress across the knee joint while the knee is degrees of flexion. A positive test produces a thud or a click, or causes pain in a reproducible portion of the range of motion ...

False-colour X-ray of a profile view of the human knee joint, showing osteoarthritic changes in the joint. The large bone at top is the femur (thigh bone), which articulates against the tibia (shin bone) and the fibula (bottom) at the knee. Immediately to the right of the head of the femur is the patella, the knee cap. In a normal, healthy joint the heads of the femur and tibia would not appear in direct contact, as they do in this image. Narrowing of the joint space due to loss of cartilage (the working surface of the joint) is a typical X-ray feature in osteoarthritis. The condition is associated with mechanical wear and is most common in persons over 50 years of age. - Stock Image M110/0158

The contribution of diet and exercise to improving knee osteoarthritis in overweight adults. Is diet and exercise more effective than exercise alone in reducing knee joint loads, inflammation and clinical outcomes?

The blood supply to the knee is complex. It is rarely relevant to knee problems and the information below will not be useful to most people with a knee injury. It is unusual for the blood supply of the knee to interfere with operations such as arthroscopy or ACL reconstruction but it can be more relevant in the case of a total knee replacement or high tibial osteotomy.. Arteries. The arteries to the knee joint and surrounding structures are supplied by the femoral and popliteal arteries. The femoral artery enters the lower limb and then sends off the large profunda femoris branch which dives deep into the thigh. The femoral artery continues closer to the surface giving off branches to the quadriceps muscle. The profunda femoris also gives off muscular branches and contributes to the circulation around the knee joint.. The femoral artery moves from the front to the back of the thigh and then to the back of the knee where it becomes the popliteal artery. Before entering the adductor canal the ...

The aim was to investigate the effects of three anatomical frames using palpable anatomical landmarks of the knee on the net knee joint moments. The femoral epicondyles, femoral condyles, and tibial ridges were used to define the different anatomical frames and the segment end points of the distal femur and proximal tibia, which represent the origin of the tibial coordinate system. Gait data were then collected using the calibrated anatomical system technique (CAST), and the external net knee joint moments in the sagittal, coronal, and transverse planes were calculated based upon the three anatomical frames. Peak knee moments were found to be significantly different in the sagittal plane by approximately 25% (p ≤0.05), but no significant differences were seen in the coronal or transverse planes. Based on these findings it is important to consider the definition of anatomical frames and be aware that the use of numerous anatomical landmarks around the knee can have significant effects on ...

Patients with anterior cruciate ligament (ACL) injury often exhibit reduced movement quality during functional tasks in the form of a knee-medial-to-foot position (KMFP). This movement pattern is suggested to be more common in women than in men, but the possible contributing sensorimotor factors for this altered knee position are poorly studied in these patients. The aim of this study was to evaluate the association between sensory function and medio-lateral knee position during functional tasks in men and women with ACL injury. Fifty-one patients (23 women) aged 18-40 years with ACL injury were included in this cross-sectional study. Measures of sensory function were assessed by the threshold to detection of passive motion (TDPM) for knee kinesthesia and by the vibration perception threshold (VPT) for vibration sense. Movement quality was assessed by visual observation of the position of the knee relative to the foot during the following four functional tasks with different degrees of difficulty: the

Even a relatively small malalignment in normal knees can cause dramatic alterations in the pressures within the knee joint, and this negative effect can be greatly magnified if the cartilage within the knee has been damaged,? says researcher Dr Joseph Guettler, orthopedic surgeon and sports medicine fellow at Duke University. At the American Orthopaedic Society for Sports Medicine?s annual meeting in Orlando, FL, last month, Dr Guettler presented the results of a study of 8 human knee joints taken from cadavers.. Using special test equipment, the research team found that just 3? of malalignment can lead to serious cartilage deformation, more than doubling the pressures on the middle of the knee joint and increasing peak contact pressures by 68%. The study found that such small malalign-ments can lead to future trouble, which may include degenerative arthritis. The researchers urged doctors to closely monitor all young people who have reconstructive knee surgery to ensure that their leg bones ...

Purpose: Knee pain is a chief symptom of knee pathology. Both acute and chronic knee pain result in altered joint loads during walking, which potentially result in mechanical and biological changes in knee articular cartilage. Due to confounding factors in clinical knee pain (effusion, muscle weakness, inflammation, structural changes), it is difficult to examine the independent effect of knee pain on walking mechanics. The purpose of this study is to examine whether unilateral experimentally induced knee pain influences bilateral loading patterns during walking in healthy individuals. Methods: This study was a controlled laboratory, cross-over trial. Each of 30 able-bodied subjects (M = 20, F = 10; 23 ± 2.4 yrs, 71 ± 12.7 kg, 178 ± 8.2 cm) completed three experimental sessions: pain (5.0% NaCl infusion), sham (0.9% NaCl infusion), and control (no infusion) in a counterbalanced order, 2 days apart (a washout period). For the experimental sessions, hypertonic (5% NaCl) or isotonic (0.9% NaCl) ...

Arthritis in knee joints the type of problem for people over 60 years. It occurs as for the cartilage at the saturday and sunday the bones wearing out into the future. Just like a car engine contains parts that wear out within use, the body also has parts that wear outdoor. For knee joints, the cartilage is during the ends of the femur challenging to make tibia which makes up the joint. If someone played sport throughout their younger years and created a knee injury, the chance of developing problems in the future is significantly increased. So what you can do about knee Arthritis? With success, the best form towards Treatment or management is just exercise. When pain develops with the knee, the muscles often waste away unfortunately the pain and because who will doesnt use the knee as numerous. The important muscles to be able to on developing are the quadriceps muscle that hamstrings. The quadriceps or quadriceps muscle is found at the cab end of the knee or thigh and is accountable to ...

This study shows that knee pain is common in the age group 35-54 with radiographic evidence of OA according to either the Kellgren & Lawrence or the Ahlbäck classifications in a smaller proportion. It is interesting to note that for most people with chronic knee pain no structural changes were found on radiographs.. Longstanding knee pain (≥ 1 month) in populations aged 55 years or above has been found to be strongly associated with disability, irrespective of underlying diagnosis.8 The prevalence of knee pain in the adult population, previously studied mainly without attempt to correlate to the presence of OA have shown prevalence figures of 14.2% for men and 12.7% for women (ages 18-84)9 and 17% for men and 23% for women aged 55-59,8 respectively. In our study, prevalence figures of 15% show that the problem of chronic knee pain is not restricted to higher ages.. The diagnosis of OA in epidemiological studies is most often based on the results of evaluation of standard radiographs with or ...

Knee pain as a result of osteoarthritis of the knee is one of the leading causes of disability in the United States. It develops slowly and the pain it causes worsens over time. Although there is no cure for osteoarthritis, there are many treatment options available to help people manage pain and stay active. Clinicians frequently rely on knee joint injections to treat knee pain and stiffness associated with inflammation. Acute and chronic knee pain results in a decrease in joint mobility that often leads to a reduction in daily activity. This can ultimately affect the physical health and emotional well-being of a patient.

An artificial knee joint comprising: a femoral component comprising a femoral condylar portion made of a medial condylar section and a lateral condylar section which extend in an anteroposterior direction of the knee joint and have convex exterior surfaces, and a tibial component comprising a tibial condylar portion made of a medial condylar section and a lateral condylar section which extend in an anteroposterior direction of the knee joint and have concave interior surfaces so as to slidably receive the medial and lateral condylar sections of the fermoral condylar portion therein; and a space between the respective medial and lateral condylar sections of the femoral condylar portion and of the tibial condylar portion being formed so as to be gradually narrower toward the rear side of the knee joint, thus forming a

Bone is integral to the pathogenesis of osteoarthritis (OA). Whether the bone area of the tibial plateau changes over time in subjects with knee OA is unknown. We performed a cohort study to describe this and identify factors that might influence the change. One hundred and twenty-six subjects with knee OA underwent baseline knee radiography and magnetic resonance imaging on their symptomatic knee. They were followed up with a repeatmagnetic resonance image of the same knee approximately 2 years later. The bone area of the tibial plateau was measured at baseline and follow-up. Risk factors assessed at baseline were tested for their association with change in tibial plateau bone area over time. One hundred and seventeen subjects completed the study. The medial and lateral tibial plateau bone areas increased by 2.2 ± 6.9% and 1.5 ± 4.3% per year, respectively. Being male (P = 0.001), having a higher body mass index (P = 0.002), and having a higher baseline grade of medial joint-space narrowing (P = 0.01

There is a greater risk of tibial component loosening when mobile unicompartmental knee replacement is performed in anterior cruciate ligament deficient knees. We previously reported on a cohort of anterior cruciate ligament deficient patients (n=46) who had undergone surgery, but no difference was found in implant survivorship at a mean 5-year follow-up. The purpose of this study was to examine the kinematic behaviour of a subcohort of these patients.The kinematic behaviour of anterior cruciate deficient knees (n=16) after mobile unicompartmental knee replacement was compared to matched intact knees (n=16). Sagittal plane knee fluoroscopy was taken while patients performed step-up and forward lunge exercises. The patellar tendon angle, knee flexion angle and implant position was calculated for each video frame.The patellar tendon angle was 5° lower in the deficient group, indicating greater anterior tibial translation compared to the intact group between 30 and 40° of flexion. Large variability,

Purpose The purpose of this study was to quantify changes in knee loading in the three clinical planes, compensatory gait adaptations and patient-reported outcome measures (PROMS) resulting from opening wedge high tibial osteotomy (HTO). Methods Gait analysis was performed on 18 participants (19 knees) with medial osteoarthritis (OA) and varus alignment pre- and post-HTO, along with 18 controls, to calculate temporal, kinematic and kinetic measures. Oxford Knee Score, Knee Outcome Survey and visual analogue pain scores were collected. Paired and independent sample tests identified changes following surgery and deviations from controls. Results HTO restored frontal and transverse plane knee joint loading to that of the control group, while reductions remained in the sagittal plane. Elevated frontal plane trunk sway (p = 0.031) and reduced gait speed (p = 0.042), adopted as compensatory gait changes pre-HTO, were corrected by the surgery. PROMs significantly improved (p ≤ 0.002). Centre of ...

The gold standard for measuring knee alignment is mechanical axis determined using full-limb radiographs (FLR). Measurement of joint alignment using antero-posterior (AP) knee radiographs is more accessible, economical and involves less radiation exposure to the patient compared with using full-limb radiographs. The aim of this study was to compare and assess the reproducibility of knee joint axial alignment on full-limb radiographs and conventional AP knee radiographs. Knee alignment was measured in 40 subjects (80 knees) from the TwinsUK registry. Measurement of mechanical knee alignment was from FLR, and anatomic knee alignment from weight-bearing AP knee radiographs. Reproducibility was assessed by intra-class correlation coefficients and kappa statistics. Reproducibility of knee alignment for both methods was good, with intra-observer ICCs of 0.99 for both FLR and AP radiographs. The mean alignment angle on FLR was 178.9 degrees (SD 2.1, range 173-183 degrees ), and 179.0 degrees (SD 2.1, range

No data are available to describe six-degree-of-freedom (6-DOF) knee-joint kinematics for one complete cycle of overground walking following total knee arthroplasty (TKA). The aims of this study were firstly, to measure 6-DOF knee-joint kinematics and condylar motion for overground walking following TKA; and secondly, to determine whether such data differed between overground and treadmill gait when participants walked at the same speed during both tasks. A unique mobile biplane X-ray imaging system enabled accurate measurement of 6-DOF TKA knee kinematics during overground walking by simultaneously tracking and imaging the joint. The largest rotations occurred for flexion-extension and internal-external rotation whereas the largest translations were associated with joint distraction and anterior-posterior drawer. Strong associations were found between flexion-extension and adduction-abduction (R2 = 0.92), joint distraction (R2 = 1.00), and anterior-posterior translation (R2 = 0.77), providing

A group of researchers from Clinical Research & Services/Biomechanics at Ottobock in Gottingen, Germany, and Vienna, Austria, set out to describe the sagittal kinetic and kinematic gait characteristics of the ankle and residual knee joint of the prosthetic limb and the knee loading parameters of the sound side of people with unilateral below-knee amputations. The researchers noted that previous literature revealed inconsistent findings on kinetic parameters for determining the risk of developing knee osteoarthritis, such as the peak knee adduction moment, knee flexion moment, and vertical ground reaction forces.. The team used gait analyses from 53 people with unilateral below-knee amputations and compared them to a control group, both taken from an Ottobock database. They evaluated the sagittal kinetic and kinematic gait characteristics of the ankle and residual knee joint of the prosthetic limb, and the peak knee adduction moment, knee flexion moment, and vertical ground reaction forces of the ...

The objective of this study was to investigate the relationship of cartilage loss and bone marrow lesions (BMLs) in the medial and lateral patellofemoral joint (PFJ) to knee pain. The location of full-thickness cartilage loss and BMLs in the PFJ on knee magnetic resonance imaging (MRIs) from the Multicenter Osteoarthritis (MOST) and Framingham Osteoarthritis (FOA) Studies were categorized as no damage, isolated medial, isolated lateral, or both medial and lateral (mixed). The relationship of MRI lesions in each PFJ region to prevalent knee pain were determined. Differences in knee pain severity were compared among categories of PFJ full-thickness cartilage loss and BMLs using quantile regression. In MOST (n=1137 knees), compared with knees without full-thickness cartilage loss, knees with isolated lateral or mixed PFJ full-thickness cartilage loss had 1.9 (1.3, 2.8) and 1.9 (1.2, 2.9) times the odds of knee pain, respectively, while isolated medial cartilage loss had no relationship to knee ...

A striking finding of this study was that over 75% of our patients with so called primary symptomatic osteoarthritis had meniscal damage. These patients did not report knee trauma or experience an acute knee pain exacerbation; they were selected according to the well recognised ACR criteria for the classification of knee osteoarthritis.28 This finding is in agreement with previous studies that reported that 52-92% of patients with symptomatic knee osteoarthritis present with meniscal damage when assessed by MRI.38-40 So far, very few studies have used MRI to examine the in vivo change in cartilage volume over time in correlation had damage in a population with symptomatic knee osteoarthritis. Our original longitudinal MRI study of 32 subjects with symptomatic osteoarthritis of the knee already showed a significant global cartilage volume loss (−6.1%) at two years of follow up (p,0.0001).34 We further showed in this study that the loss of cartilage volume in the medial compartment of the knee ...

Abstract: In this study, joint reposition sense of the knee in a non-weight-bearing (NWB) state and that in a weight-bearing (WB) state were compared, and it was determined whether a significant relationship existed between knee displacement (KD) and joint reposition sense. The dominant knees of 8 male and 12 female subjects (age 19-26 years, M ± SD = 21.5 ± 2.06) who had no previous history of knee dysfunction were tested for accuracy of angular reproduction in the WB and NWB states. There was a significant difference in the accuracy of angular repositioning between the two conditions, with the WB test having less deviation from the predetermined angle. There was a weak relationship between KD and the ability to reproduce specific angles of the knee. These results suggest that the WB or closed chain state of the knee was more accurate in the determination of joint position sense than the NWB or open chain condition. Comparison of weight bearing and non-weight bearing conditions on knee joint ...

Introduction: Motion loss of the knee can result from a variety of causes and poses a difficult clinical problem. We intended to study functional outcome of intrarticular knee stiffness due to various etiology treated with arthroscopic arthrofibrolysis and patient satisfaction and quality of life with IKDC and Oxford knee score.. Material and Method: Fifty five cases were screened with stiff knee from June 2011 to December 2012.We included 25 cases which were intrarticular stiff knees. Inclusion criteria were intrarticular knee stiffness due to post traumatic etiology, good patellofemoral mobility and good skin condition of knee joint. We excluded extrarticular causes of knee stiffness, and active infection of knee. All patient under went arthroscopic adhesiolysis. Preoperative range of movement, IKDC score and Oxford knee score was compared with 1 year follow up score. During post operative period supervised physiotherapy was carried out and CPM (Continuous passive motion) was applied to all ...

Knee replacement is a surgery to replace a damaged, worn or diseased knee with an artificial joint. The goal of knee replacement is to relieve pain, restore proper function of the knee joint and improve the quality of life.. Why Is It Done?. Knee replacement surgery is taken into consideration when there is severe knee pain or stiffness, moderate but continuous knee pain, chronic knee inflammation & swelling & knee deformity. Knee surgery is recommended for older people, although adults or teenagers of any age can be candidates for the procedure, since they are very active physically and will wear the joint out rapidly. The gender, weight or age of the person is never a factor when making an allowance for knee replacement surgery.. What Happens During the Surgery?. Once you are under spinal/epidural anesthesia or local anesthesia. An 8 to 12 inch slit is made in the knee front. The injured part of the joint is detached from the surface of the bones, and the surfaces are then molded to grasp a ...

Abnormal loading of the knee joint contributes to the pathogenesis of knee osteoarthritis. Gait retraining is a noninvasive intervention that aims to reduce knee loads by providing audible, visual, or haptic feedback of gait parameters. The computational expense of joint contact force prediction has limited real-time feedback to surrogate measures of the contact force, such as the knee adduction moment. We developed a method to predict knee joint contact forces using motion analysis and a statistical regression model that can be implemented in near real-time. Gait waveform variables were deconstructed using principal component analysis, and a linear regression was used to predict the principal component scores of the contact force waveforms. Knee joint contact force waveforms were reconstructed using the predicted scores. We tested our method using a heterogenous population of asymptomatic controls and subjects with knee osteoarthritis. The reconstructed contact force waveforms had mean (SD) ...

KNEE REPLACEMENT In the contemporary times, our lifestyle habits pose a serious challenge to our body and the knees are the first to bear the brunt of these changes. Owing to such habits, many people experience knee pain caused by wear and tear, an injury or hectic routine. Some other people suffer similar pain due to aging and arthritis.. What is Knee Replacement? A total knee replacement is a surgical procedure whereby the diseased knee joint is replaced with artificial material, metal and plastic components shaped to allow continued motion of the knee.. Indications Total knee replacement can be performed to correct mild valgus (outward bending) or varus (Inward bending) deformity, if one experiences extreme pain when performing physical activities requiring a range of movement in the knee joint..

The purpose of this study was to investigate the effects of high-impact exercise on bone mineral mass and strength, and on knee cartilage composition in postmenopausal women with mild knee osteoarthritis (OA). In addition, the association between knee OA and femoral neck bone structural characteristics in women with mild knee radiographic OA and those without radiographic knee OA was studied. Also, the reproducibility of measuring human knee joint cartilage by the delayed gadolinium-enhanced MRI (dGEMRIC) technique was determined in healthy asymptomatic subjects. Data from a 12-month randomized controlled trial (RCT) was used to assess the effects of exercise on bones and cartilages. The training intervention comprised 80 postmenopausal women with mild knee OA. The primary outcomes were bone mineral mass and strength, and the biochemical composition of knee cartilage as assessed by quantitative MRI measures: dGEMRIC and T2 relaxation time. Physical performance-related risk factors of falling ...

Lateral wedge insoles are traditionally used to reduce the adduction moment that crosses the knee during walking in people with medial knee osteoarthritis. However, the best degree to reduce knee joint load is not yet well established. Electronic databases were searched from their inception until May 2017. Included studies reported on the immediate biomechanical effects of different degrees of lateral wedge insoles during walking in people with knee osteoarthritis. The main measures of interest relating to the biomechanics were the first and second peak of external knee adduction moment and knee adduction angular impulse. For the comparison of the biomechanical effects of different degrees of insoles, the studies were divided in three subgroups: insoles with a degree higher than 0° and equal to or lower than 5°; insoles higher than 5° and equal to or lower than 9°; and insoles higher than 9°. Eligible studies were pooled using random-effects meta-analysis. Fifteen studies with a total of 415

How are Knee Braces Helpful in Regard to Treating Knee Injuries?. Below are few reasons that can explain answer to this question. 1: Reduce Inflammation:. Knee braces is a non-invasive method for the reduction of inflammation by redistributing the weight on knee so that Pressure is not confined to specific area and you feel free to walk, climb, jump or bend. Although this depends on the type of knee brace bought and used.. 2: Provide Extreme Support and Strength:. Knee braces provide an extreme amount of support when you stand, walk, climb, jump or exercise. They bind to your knee keeping it in place and avoid slipping of knee. Knee Braces are itself a reminder to minimize pressure on knee.. 3: Minimizes Pain and Provide Relaxation:. Knee braces minimizes pain by covering knee so that dust particles and Bacteria do not infect it further. They also protect knee from further inflammation and thus provide peace of mind. People affected with knee injuries feel more relaxed, at peace when the knee ...

Cycling after Arthroscopic Knee Surgery: Cycling is a low-impact form of exercise. Low-impact exercises put minimal stress on your knee joint. Your Arthroscopic Knee Surgeon in Mumbai will tell you when it is safe to resume swimming after your arthroscopic knee surgery.. Set Realistic Goals: You have to keep that belief that yes you will return to the tennis court or the athletics field and get back to playing your favorite sport again. But then it will take time for your operated knee to perform the different/difficult sporting movements so mentally prepare yourself for the challenge ahead.. Make Lifestyle Changes: Give your knee a good rest, eat a well- balanced diet and also sleep well for at least 8 hours in the night. If you play high-impact sports then for some time you should switch to low-impact sports like cycling, swimming and light activities like brisk walking, jogging etc.. Wear a Knee Brace: A knee brace is something that will provide that proper support to your knee as you heal ...

Knee braces can be subdivided into four categories based on their intended use. One category of braces, unloader knee braces, is specifically designed to provide pain relief in arthritic knees. Unloader knee braces, also referred to as off-loader knee braces, are typically custom-made (custom fabricated, custom molded) and are considered for individuals who are unable to be fitted with a prefabricated (off-the-shelf) knee brace. Individuals with osteoarthritis of the knee with varus or valgus deformity often develop increased pain in the affected compartment due to increased mechanical loading. Unloader knee braces are designed and constructed to reduce the asymmetric loading in such knees. In order to decrease the weight on a painful knee joint, an unloader knee brace is designed to provide stability during activities of daily living. There is biomechanical data demonstrating reduction in adduction movement in varus knees when the appropriate unloader brace is used. In a systematic review of ...

Whilst patellofemoral pain is one of the most common musculoskeletal disorders presenting to orthopaedic clinics, sports clinics, and general practices, factors contributing to its development in the absence of a defined arthropathy, such as osteoarthritis (OA), are unclear. The aim of this cross-sectional study was to describe the relationships between parameters of patellofemoral geometry (patella inclination, sulcus angle and patella height) and knee pain and patella cartilage volume. 240 community-based adults aged 25-60 years were recruited to take part in a study of obesity and musculoskeletal health. Magnetic resonance imaging (MRI) of the dominant knee was used to determine the lateral condyle-patella angle, sulcus angle, and Insall-Salvati ratio, as well as patella cartilage and bone volumes. Pain was assessed by the Western Ontario and McMaster University Osteoarthritis Index (WOMAC) VA pain subscale. Increased lateral condyle-patella angle (increased medial patella inclination) was associated

Injuries can promote pain in the knee. Any traumatic event can cause damage to ligaments attached to the knee joint. As knee has four ligaments attached to it exact area of pain can help the doctor to find out the particular ligament that has been damaged. Pain occurs when weight is transferred on the joint. Swelling of tendons also referred as tendinitis or jumpers knee, injuries caused to meniscus by sharp and quick movements can cause mild to severe pain in the knee joint. The pain due to tearing of meniscus is felt with a popping sensation and locking or feeling of unstable knee. Swelling of tendons causes pain below the knee cap or at the back of the knee joint. All of these knee pains may also occur due to old age or overuse of the knee joint like in sports and other activities.. Because there are a lot of athletes in Nebo, knee braces are becoming really popular and the market for this has grown over the years. Knee braces are certainly beneficial for runners, but the biggest concern ...

How does knee osteoarthritis cause pain?. The knee consists of a weight bearing, flexible joint which is inclined to wear and tear. This increases the chances of developing osteoarthritis. A knee that is arthritic will have a missing, injured or thin cartilage in the joint. This damaged cartilage is not the reason for the pain; instead it causes friction between the bones. This friction leads to knee pain and other problems.. Knee joint structure. Unless the knee has gone through some sort of trauma, the main cause of knee pain is arthritis which is usually osteoarthritis. When the cartilage in the knee has deteriorated by thinning, damage or wearing away of the joint then new cartilage will have to be created. The new cartilage cells may not grow in a normal smooth way, instead they may be bumpy. This will result in the shin bone and the thigh bone rubbing together in the knee joint. Knee osteoarthritis usually starts with cartilage in the shin and thigh bones deteriorating. To make up for the ...

Adrenomedullin is a potent vasodilatory and hypotensive peptide as well as an endogenous immunomodulatory factor with predominantly anti-inflammatory effects. The purpose of the present study was to evaluate the therapeutic effects of adrenomedullin in rabbits with antigen-induced arthritis, an experimental model of rheumatoid arthritis. Following the induction of arthritis in both knee joints by ovalbumin injection into the joint spaces of pre-immunized rabbits, increasing daily doses of adrenomedullin were injected into the knee joint spaces or saline was injected into the contralateral knee joint spaces as the control. For time-course experiments, adrenomedullin and saline were injected into the knee joint spaces daily for 7 days and 20 days. The degree of joint swelling and the histological change in the knee joints injected with adrenomedullin were compared with the control knee joints. Histological evaluation of the infrapatellar fat pads and synovial tissue was performed. TNFα, IL-6, vascular

The purpose of this study was to compare four common rehabilitation exercises used in physical therapy clinics for activating the vastus medialis oblique (VMO) and vastus lateralis (VL). Thirty-four subjects, aged 22-28 years, without patellofemoral pain syndrome (PFPS) (18 females and 16 males) were recruited. Subjects performed four exercises-straight leg raise with neutral and externally rotated hip positions (SLRN, SLRER), and short arc quad with neutral and externally rotated hip positions (SAQN, SAQER). The integrated electromyographic (iEMG) activity of the VMO and VL and were recorded, with means of the VMO, VL and VMO/VL compared across exercises. No significant difference was found for the VMO/VL ratio across the four exercises (p=0.147). However, for the VMO and VL individually, a significant difference was found (p=0.0001), SAQER was significantly greater than SLRN and SLRER; SAQN was significantly greater than SLRN and SLRER. These findings suggest that exercises including short arc quad

N2 - Unicompartmental knee replacements have not performed as well in the lateral compartment as in the medial. This may be because the tibial components have flat or slightly concave surfaces which match the medial plateau but not the convex lateral plateau. The aim of this study was to find the optimal radius for a convex lateral tibial component.Twelve normal lateral tibial plateau were retrieved at knee replacement, and their surface contour in their mid sagittal plane was determined. The optimal circle was fitted and its radius measured. A series of different shaped tibial components were superimposed. From published information about the position of the femoral condyle relative to the tibia in different degrees of flexion, the flexion gap at these angles was determined.The average radius of the lateral tibial plateau was 40 ...

MODEL RELEASED. Partial knee replacement surgery. Clip 25 of 48. Close-up of surgeons operating on the knee of a patient undergoing a partial knee replacement. This is called unicompartmental arthroplasty (UKA). UKA involves replacing just one of the three knee compartments, rather than the whole knee. It is usually carried out to treat osteoarthritis or injury of that knee compartment. The knee is accessed through an incision that is smaller than that for a total knee replacement. Bone and tissue is removed using clippers, drills, hammers and saws. Implants are added and secured in place, and the wound is then closed with sutures.

Magnetic resonance imaging provides excellent volumetric detail but is static. Fluoroscopic imaging provides for dynamic observation of knee kinematics but provides no direct observation of the soft-tissue structures. We attempted to answer the question Are knee kinematics the same during static and dynamic squatting? Methods: Knee kinematics data from two previously reported studies of healthy knee kinematics during squatting from 0° to 120° were obtained. The results of the dynamic fluoroscopic study were reformatted to perform a ...

The knee is the most complex joint in the body and is formed by the articulation between the thigh bone (femur) and the shinbone (tibia). A knee cap is present over the front of the joint to provide extra protection. These bones are held together by four strong rope like structures called ligaments. Two collateral ligaments are present on either side of the knee and control the sideway movements of the knee. The other two ligaments are the anterior and posterior cruciate ligaments, ACL and PCL respectively, which are present in the centre of the knee joint and cross each other to form an X. The cruciate ligaments control the back and forth movement of the knee.. Knee ligament injuries are common in athletes involved in contact sports such as soccer, football and basketball. Knee ligament injuries are graded based on the severity of injury. In grade I the ligament is mildly damaged and slightly stretched, but the knee joint is stable. In grade II there is a partial tear of the ligament. In ...

adults suffer from frequent knee pain, which decreases mobility, impacts sleep and reduces quality of life. There is a need for drug-free pain relief for chronic knee pain. Transcutaneous electrical nerve stimulation (TENS) is a safe, non-invasive pain relief approach that has been prescribed by physicians for decades. However, most TENS devices are wired to electrodes placed on the body, which is cumbersome while active or sleeping.. Quell is the only true wearable TENS device. It is well suited for chronic knee pain because it is worn just below the knee, is not much larger than a credit card, and is comfortable enough to use 24/7.

TY - GEN. T1 - Knee joint kinetics during reactive recovery. T2 - 52nd Human Factors and Ergonomics Society Annual Meeting, HFES 2008. AU - Parijat, Prakriti. AU - Lockhart, Thurmon E.. AU - Liu, Jian. PY - 2008/12/1. Y1 - 2008/12/1. N2 - The purpose of this study was to investigate the effects of localized muscle fatigue on the knee joint kinetics during reactive recovery efforts from a slip perturbation. Sixteen healthy young participants were recruited to walk across an unexpected slippery vinyl floor surface in two different sessions (Fatigue and No fatigue). Kinematic and kinetic data were collected using a three-dimensional video analysis system and force plates during both sessions. An inverse dynamic model was developed to assess joint moment and joint power of the knees during reactive recovery period of slip-induced falls. The results demonstrated an increase in the peak knee joint moment and peak knee joint power generation in the fatigue slip trials. There were four reported falls in ...

Chronic knee pain is a common and disabling condition in people over 50 years of age, with knee joint osteoarthritis being a major cause. Acupuncture is a popular form of complementary and alternative medicine for treating pain and dysfunction associated with musculoskeletal conditions. This pragmatic Zelen-design randomised controlled trial is investigating the efficacy and cost-effectiveness of needle and laser acupuncture, administered by medical practitioners, in people with chronic knee pain. Two hundred and eighty two people aged over 50 years with chronic knee pain have been recruited from metropolitan Melbourne and regional Victoria, Australia. Participants originally consented to participate in a longitudinal natural history study but were then covertly randomised into one of four treatment groups. One group continued as originally consented (ie natural history group) and received no acupuncture treatment. The other three were treatment groups: i) laser acupuncture, ii) sham laser or, iii)

Symptoms of knee pain from running. Many runners who suffer from knee pain will often feel the pain after they have just completed a long run. The pain will usually originate from just behind the knee cap and might feel like a numbing pain rather than a sharp pain. The pain will usually aggravate when a person has climbed a flight of stairs. Other symptoms of a runners knee are when a person feels stiffness or soreness in their knees when they have sat down for long period of time. Some runners also experience a slight clicking sound when they either extend or bend their knees.. Causes of knee pain from running. Knee pain for runners is usually caused by a condition that is medically known as patellofemoral pain syndrome. Among the running community, this condition is simply known as a runners knee. In a vast majority of cases, this knee pain from running is caused by quadriceps muscles that are quite weak, especially when compared to the strength of the hamstring muscles in the same person. ...
