Methods Data were used from a previously reported study in which 83 patients with HOA were randomly assigned to CRx-102 or placebo. CRx-102 consists of prednisolone (3 mg/day) and dipyridamole (400 mg/day), and was shown to be superior to placebo. Assessments were performed at baseline and after 7, 14, 28 and 42 days, and included the Australian/Canadian osteoarthritis hand index (AUSCAN), visual analogue pain subscale (VAS) pain and patient global, and counts of distal interphalangeal (DIP), proximal interphalangeal (PIP), metacarpophalangeal and carpometacarpal (CMC) joints (tenderness, soft tissue swelling, bony enlargement, limited motion). Various combinations of patient-reported outcomes and joint counts were computed as composite scores (similar to clinical disease activity index) and tested for responsiveness. For each measure, mean change from baseline to day 42, treatment effect, standardised response mean (SRM) and relative efficiency compared with AUSCAN pain were calculated.. ...

Osteoarthritis is a very common disease and the leading cause of chronic disability in the United States. Worldwide it is estimated that around 250 million people have Osteoarthritis of the knee, which accounts for 3.6% of the total population.(3) In the United States 27 million people are living with Ostoearthritis and 8 million people in the UK.(4) Most adults over 55 years of age will have Osteoarthritis of some degree that is evident on radiography even if they are not symptomatic. The causes of Osteoarthritis are not exactly determined although genetics, gender, age, weight and ethnicity may all play a role. There is higher prevalence of osteoarthritis with advancing age and women are more likely than men to be affected.(5). Footnotes 1. Pérez Martín Á. Symptoms.

Osteoarthritis, also known as degenerative joint disease, is the most common joint disorder. It is characterized by damage of the joint cartilage and abnormalities of the bones surrounding the joint. Unlike in rheumatoid arthritis, inflammation is usually minimal in osteoarthritis. In severe cases, the entire joint surface may be destroyed, with resultant pain and disability.. The most common joints to be involved are the knees, hips, and vertebrae. The joints of the hand are also commonly affected. The most common symptom is stiffness within the joint, typically lasting less than 15 minutes per day. Over time, the stiffness progresses to pain.. Most cases of osteoarthritis occur in the absence of underlying diseases. However, several medical disorders predispose a person to osteoarthritis. These include endocrine abnormalities (e.g., hypothyroidism, diabetes, or mellitus), other joint diseases (e.g., rheumatoid arthritis, gout, or joint infection), and bone diseases (e.g., avascular necrosis or ...
A study from the University of Eastern Finland and Massachusetts Institute of Technology hows that articular cartilage degenerates specifically around injury areas when the fluid flow velocity becomes excessive.. Knee joint injuries are typically related to sports, such as football, rugby or ice hockey, but people often do not know that such injuries may lead to joint inflammation and post-traumatic osteoarthritis. In advanced post-traumatic osteoarthritis, joint cartilage breaks down completely, causing severe joint pain, lack of mobility and even social isolation.. However, the mechanisms leading to osteoarthritis are not known. Currently, it is not possible for a physician examining a patient to predict future joint condition and possible development of osteoarthritis. In the future, however, this may be possible, as a study from the University of Eastern Finland and Massachusetts Institute of Technology now shows that articular cartilage degenerates specifically around injury areas when the ...

This post is a continuation of a series of articles from the American Academy of Orthopedic Surgeons (AAOS) Full Guideline for the Treatment of Osteoarthritis.. Recommendation 10 - The AAOS is unable to recommend for or against the use of knee braces with varus directing forces for patients with lateral uni-compartmental osteoarthritis of the knee.. The reason knee braces for osteoarthritis received a "cant recommend for or against" rating is because there arent any published studies on the subject. The vast majority of patients with unicompartmental osteoarthritis are affected on the medial or inside compartments of their knees. In rare cases, usually relating to trauma, osteoarthritis can affect the lateral or outside compartment of the knee.. So to date research teams have been unable to get enough people together with lateral compartment osteoarthritis to put together a study.. ...
Diagnosis. The primary symptom of osteoarthritis is joint pain and stiffness. Sometimes the pain can be directed to some other area of the body that has a nerve connection with the joint. Patients with osteoarthritis of the hip may actually feel pain in their groin or knee. Patients with osteoarthritis of the spine may feel pain in the hip. If these symptoms are present, the doctor will order an X-ray, test the joint fluid and order blood tests to make sure there is no other disease present.. Treatment. Treatment of osteoarthritis should include medications, strength training, weight loss, minimal joint impact and surgical replacement of certain joints when necessary. Strength training is extremely important in patients with osteoarthritis. Avoiding physical activity causes the muscles around the joint to decrease in size or atrophy. As the muscles atrophy, the joint becomes less stable and that can have a negative effect on osteoarthritis. It is important to keep our body weight at ideal ...
Osteoarthritis is a common form of "arthritis", which is the general term for the inflammation of joints. It is sometimes called degenerative joint disease, which means the symptoms and problems get worse over time. This condition is characterized by the breakdown of cartilage in one or more of the joints in the body. Common forms include joints that bear much of our weight, like hip osteoarthritis or an osteoarthritis knee condition. It can also affect smaller joints, like fingers, thumbs, neck, and the big toe. Joints that have suffered from past injuries or excessive amounts of stress are more susceptible to degeneration through osteoarthritis.. The degeneration in joints is caused by damage to the cartilage that protects the joints. Cartilage is an elastic, rubber-like material that reduces the friction in the meetings points of bone joints. Imagine it functioning like a shock absorber. When osteoarthritis affects your joints, the cartilage begins to lose its elasticity and becomes stiff and ...
A team approach is recommended when getting advice on how best to manage your osteoarthritis (OA). Here are the various professionals who make up an OA team.
What is OsteoArthritis? OsteoArthritis is that you simply type of Arthritis impacting most people. The condition is a lot more prevalent among adults in particular women. Also known as the wear Arthritis or degenerative Arthritis, OsteoArthritis involves a brand new degeneration or deterioration of a particular joint or group associated with joints. Weight-bearing joints such as those based in the arms, legs, back, and hips are the primary locations of the break point. This is not to exclude OsteoArthritis down to inflammation and injury throughout the smaller joints such as those who work in the fingers. The seam, particularly the cartilages below it joints, are worn down because of everyday activities, strenuous thing, injury, fatigue, and dehydration. This degeneration of the joints could result to structural changes of all your joints, joint effusion, bone spurs or bone overgrowths that cause Osteophytes, and muscle therefore joint weakness. People experience OsteoArthritis differently and ...
Osteoarthritis represents a major therapeutic challenge to medical and health-care providers. In part, this is related to the limited tools that are available for assessing the structural state of joint tissues and to the lack of effective therapies to alter the natural history of osteoarthritis progression. From a clinical and pathologic perspective, osteoarthritis is not a homogeneous disorder, and the underlying pathogenic mechanisms differ among individuals. Even in the same individual, the pathologic processes and etiologic mechanisms may differ at specific stages of disease progression. In the development of strategies for effective intervention, several issues need to be considered. First, the stage of osteoarthritis progression must be considered. Therapies that are effective prior to the development of structural alterations may have limited utility in later stages. Similarly, treatments for late-stage osteoarthritis need to be adapted and adjusted to target specific symptoms that are ...

Loss of glycosaminoglycan (GAG) chains of proteoglycans (PGs) is an early event of osteoarthritis (OA) resulting in cartilage degradation that has been previously demonstrated in both huma and experimental OA models. However, the mechanism of GAG loss and the role of xylosyltransferase-I (XT-I) that initiates GAG biosynthesis onto PG molecules in the pathogenic process of human OA are unknown. In this study, we have characterized XT-I expression and activity together with GAG synthesis in human OA cartilage obtained from different regions of the same joint, defined as normal, late-stage or adjacent to late-stage. The results showed that GAG synthesis and content increased in cartilage from areas flanking OA lesions compared to cartilage from macroscopically normal unaffected regions, while decreased in late-stage OA cartilage lesions. This increase in anabolic state was associated with a marked upregulation of XT-I expression and activity in cartilage next to lesion while a decrease in the
Osteoarthritis can be classified as primary or secondary. Primary osteoarthritis has an unknown cause, while secondary osteoarthritis is caused by another disease, infection, injury, or deformity. Osteoarthritis is characterized by the breakdown of cartilage in the joint. As the cartilage wears down, the bone ends may thicken, forming bony growths or spurs that interfere with joint movement. In addition, bits of bone and cartilage may float in the joint space and fluid-filled cysts may form in the bone, limiting joint movement. Several risk factors are associated with osteoarthritis, including the following:. ...

Dr Scott Ritterman offers treatment for osteoarthritis also called degenerative joint disease in Exton, Coatesville and Pottstown, PA.
Also known as "wear-and-tear" arthritis, osteoarthritis is a condition that destroys the smooth outer covering (articular cartilage) of bone. As the cartilage wears away, it becomes frayed and rough, and the protective space between the bones decreases. During movement, the bones of the joint rub against each other, causing pain.. Among the over 100 different types of arthritis conditions, osteoarthritis is the most common.. The most common symptom of osteoarthritis is pain in the affected joint(s) after repetitive use. The goal of treatment in osteoarthritis is to reduce joint pain and inflammation while improving and maintaining joint function.. ...
Among the most prevalent joint diseases is OsteoArthritis of cash knee. It occurs when your neighborhood cartilage suffers gradual loss. According to doctors, the cartilage serves as a cushion layer situated between the knee bones. Also called the degenerative joint disease, OsteoArthritis could additionally your affect other body seam. When the cartilage deteriorates, the knee joint feels painful. In the last steps from the disease, the pain which discomfort is unbearable. Like, the sick person would not walk steadily or even try to move their very own knee freely. Since the cushion between two bones never will exists after degeneration, any movement makes friction. This is because your neighborhood bones will grind against each other. The result is intolerable soreness and discomfort. The causes of OsteoArthritis are numerous. Nonetheless the, not all the cases of the disease are judges similar, in terms which are severity and frequency. Let me suggest a brief outline of the known causes: • ...
And meniscal tears spell increased osteoarthritis risk. Ironically, meniscectomy - surgical removal of some or all of the meniscus to relieve this condition - further elevates a patients risk of developing osteoarthritis over the long haul.. Throw in all the other accumulated twists and sprains and crunches of the passing years, season with a lifelong pinch of gravity, and youve got the recipe for a huge serving of osteoarthritis: 27 million sufferers in the United States alone.. In a study published in Nature Medicine, Stanford immunologist Bill Robinson, MD, PhD, and his collegues have now shown how an initial insult, such as a torn meniscus, triggers a cascade of low-grade-inflammatory activities in the joint that can result in the cartilage destruction that is osteoarthritis.. This discovery is a big deal because right now there are no decent drugs to slow, halt, or reverse the course of osteoarthritis - just painkillers providing symptomatic relief as the disease worsens.. But by ...
We previously reported that a thienoindazole derivative TD-198946 (TD) induced chondrogenic differentiation in vitro without promoting hypertrophy, and prevented and repaired the degeneration of articular cartilage observed in a surgically induced mouse model of osteoarthritis (OA).1 In that study, the TD injections into mouse knee joints began on the day of the OA surgery (prevention model) or 4 weeks after the surgery (repair model), and continued periodically until 8 weeks after the surgery.1. Here we report the disease-modifying effects of TD injections on progressed OA in mice. We examined 4-week and 8-week injection protocols that began 8 weeks after the OA surgery (figure 1A). Eight mice in each group (n=8) were then subjected to histopathological assessments of knee joint OA. The severity of OA was quantified using the Osteoarthritis Research Society International histopathology scoring system (scale: 0-6)2 on histological sections stained with Safranin O/fast green. The OA surgery, ...
While it may be tempting to use joint discomfort as an excuse not to exercise, people with osteoarthritis wont find significant pain relief unless they keep moving. According to the National Arthritis Foundation, moderate exercise is an essential component of any successful osteoarthritis treatment plan.. More than 40 million people in this country suffer from osteoarthritis, making it one of the leading causes of disability. It is the most common form of arthritis experienced by older people and can lead to chronic pain and stiffness in the hands, neck, back, knees, hips and feet. Osteoarthritis is the result of years of wear and tear on the cartilage, which is the tissue that cushions the ends of our joints.. When the cartilage is compromised, bones rub together causing pain, swelling and stiffness. Some sufferers mistakenly believe that "resting" the joints is the best way to relieve their symptoms. The fact of the matter is that moderate exercise helps maintain flexibility and reduces pain. ...
Check out these best foods for osteoarthritis, and worst foods for osteoarthritis. The osteoarthritis diet even is known to assist in osteoarthritis prevention.
Degenerative joint disease, also known as osteoarthritis (OA), is a leading cause of adult disability and affects over 30 million American adults. Direct costs for osteoarthritis and other non-traumatic joint disorders top $80 billion a year and will grow significantly in coming years. Beyond costs, care for this disease is frequently uncoordinated, varies dramatically, and often does not follow evidence-based guidelines.. Initial payment reforms have focused on joint replacement surgery, and those have shown promise in reducing costs and improving outcomes. Theres further opportunities to move upstream and help people at earlier stages, which may help many avoid surgery and improve outcomes and experiences for a much broader group of people.. On January 26, 2018, Duke-Margolis, in partnership with the Duke Department of Orthopaedic Surgery and Department of Surgery and Perioperative Care at Dell Medical School at UT-Austin and supported by Pfizer, convened stakeholders from across the health ...
Osteoarthritis affects the whole joint structure with progressive changes in cartilage, menisci, ligaments and subchondral bone, and synovial inflammation. Biomarkers are being developed to quantify joint remodelling and disease progression. This article was prepared following a working meeting of the European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis convened to discuss the value of biochemical markers of matrix metabolism in drug development in osteoarthritis. The best candidates are generally molecules or molecular fragments present in cartilage, bone or synovium and may be specific to one type of joint tissue or common to them all. Many currently investigated biomarkers are associated with collagen metabolism in cartilage or bone, or aggrecan metabolism in cartilage. Other biomarkers are related to non-collagenous proteins, inflammation and/or fibrosis. Biomarkers in osteoarthritis can be categorised using the burden of disease, investigative, prognostic, efficacy
Osteoarthritis is the most commonly occurring of the about 200 types of arthritis according to medical experts. The disease indeed comes with age and it spares no one. By age forty, 90 percent of all individuals will have x-ray findings in their joints that one consistent with osteoarthritis although many will still be without symptoms.. The experts added that by age 55, at least 80 percent of all people will occasionally or continually experience a symptom or two of the disease, which include morning stiffness, pain, tenderness and limitation of movement of the involved joints.. Medical experts are unanimous in their assessment that the joints usually affected by osteoarthritis are those of the fingers and toes, between the thumb and the hands, between the big toes and the feet, the hips, the knees, the neck and the lower back.. Moreover, they stressed that osteoarthritis is generally attributed to the wear and tear that occurs in a joint because of use. Changes in the joint include erosion of ...
Inappropriate biomechanics, namely wear-and-tear, has been long believed to be a main cause of osteoarthritis (OA). However, this view is now being re-evaluated, especially when examined alongside mechanobiology and new biomechanical studies. These are multiscale experimental and computational studies focussing on cell- and tissue-level mechanobiology through to organ- and whole-body-level biomechanics, which focuses on the biomechanical and biochemical environment of the joint tissues. This review examined papers from April 2015 to April 2016, with a focus on multiscale experimental and computational biomechanical studies of OA. Assessing the onset or progression of OA at organ- and whole-body-levels, gait analysis, medical imaging and neuromusculoskeletal modelling revealed the extent to which tissue damage changes the view of inappropriate biomechanics. Traditional gait analyses studies reported that conservative treatments can alter joint biomechanics, thereby improving pain and function ...
Researchers have for the first time established that the painful and debilitating symptoms endured by osteoarthritis sufferers are intrinsically linked to the human body clock. Body clocks within cartilage cells - or chondrocytes - control thousands of genes which segregate different biological activities at different times of the day. The body clock, researchers realised, controls the equilibrium between when chondrocyte cells are repaired during rest and when they are worn down through activity. But the research revealed that as we age, our cartilage cell body clocks deteriorate, making the repair function insufficient, which could contribute to osteoarthritis. The team examined three types of human cartilage under the microscope : normal, mildly affected by osteoarthritis and severely affected. As the osteoarthritis became more severe, the number of cells that express BMAL1 - a protein which controls the body clock - became less and less. And in terms of aging, he found similar reduction of ...
Etiology, epidemiology, and impact of osteoarthritis on an individual, society, and nation and the main principles of management of this disease are reviewed in the article. Treatment should be tailored to the needs of an individual patient. Physicians should be familiar with pharmacologic and nonpharmacologic treatment modalities to maximize effective utilization and a thorough understanding of short- and long-term complications and costs. Severity of osteoarthritis should be taken into physicians and patients consideration while applying an appropriate treatment. A stepwise management of osteoarthritis has to be taken into account. As effective interventions remain underused, state arthritis programs, including osteoarthritis programs, have to be developed to build an appropriate scientific base in public health, observe burden and impact, assess and disseminate evidence-based interventions, and work to reduce and delay disability, and improve quality of life among people with arthritis. Adequate
The great success of targeted biologic therapy against rheumatoid arthritis (RA) in recent years has meant that much research has been devoted to investigating the pathophysiology of osteoarthritis (OA) in the hope of defining novel therapeutic targets. In contrast to RA, with its pannus and erosions, OA has long been thought of as a degenerative disease of cartilage, with secondary bony damage and osteophytes. But in recent years, the importance of the synovium, and in particular the synovial macrophages, in OA, has been highlighted in both in vitro and in vivo studies. This review will discuss the potential of synovial macrophages and their mediators, in particular the proinflammatory cytokines tumour necrosis factor α and interleukin-1, as potential therapeutic targets in OA.. ...
Joint Degeneration. Causes: Typically, joint degeneration can occur in most people as they age. At times, degeneration can be referred to as "wear and tear". Degeneration of the joint surface, for example, can be accompanied by an overgrowth of bone, narrowing of the joint space and deformity of the joint. Osteoarthritis is a form of joint degeneration and may present in numerous joints of the body including the spine, hips and knees.. There are various factors that have been associated with joint degeneration, such as osteoarthritis, including heredity, injury, fractures and overuse. However, certain conditions can also play a role including metabolic disorders and gout. Furthermore, obesity or being overweight has been associated with a greater risk to develop osteoarthritis of the knee.. Symptoms: The presentation of signs and symptoms can vary greatly depending on the affected joint and area of the body. Generally, symptoms may include:. ...

Osteoarthritis (OA), also known as degenerative joint disease, is one of the most common causes of lameness in pets. It is caused by a deterioration of joint cartilage, followed by pain and loss of range of motion of the joint. Cartilage is a smooth, resilient tissue that lines the joints, allowing nearly frictionless joint movement, and providing shock absorption. Disruption of cartilage leads to increased friction and inflammation in the joints. This erodes the bone and can cause formation of new bone, called osteophytes (bone spurs), which interfere with normal joint movements causing pain. Eventually, the joint cartilage can wear away to the point that the underlying bone, named subchondral bone, is actually grinding against the adjacent subchondral bone. Because subchondral bone is rich in nerve supply, having exposed subchondral bone is a main source of pain with OA. Osteoarthritis is more prevalent in overweight pets than their non-overweight siblings. OA is diagnosed by a thorough ...

I thought aboutdrawing two different joints to show us the differencebetween rheumatoid and osteoarthritis. But then I thought showingit on the same picture might be easier to see the differences. But on this side well keepit rheumatoid arthritis, and the other side, green,will be osteoarthritis. Lets start with thepathophysiology of osteoarthritis. which is overuse. This is where elderlypeople, or people who are carrying a lot of extraweight, or have extra wear and tear on their jointstend to get osteoarthritis. And first things first, wehave our joint space here, this is a synovial joint, so it moves. These two bones move against each other. These are gonna be the bone parts.. Were not gonna do very much with them, we care about where they come together. This yellowish layer yousee here, is cartilage. Its kind of a cushionbetween the two bones. We dont want the two bonesto rub against each other. This soft, waxy cartilage,do rub against each other. Now over here we have the synovium, ...
Wnt and Rho GTPase signaling play critical roles in governing numerous aspects of cell physiology, and have been shown to be involved in endochondral ossification and osteoarthritis (OA) development. In this review, current studies of canonical Wnt signaling in OA development, together with the differential roles of Rho GTPases in chondrocyte maturation and OA pathology are critically summarized. Based on the current scientific literature together with our preliminary results, the strategy of targeting Wnt and Rho GTPase for OA prognosis and therapy is suggested, which is instructive for clinical treatment of the disease.
Read about Osteoarthritis - includes the Symptoms, treatments, Causes, complications, and Prevention. Osteoarthritis (OA), which is also known as osteoarthrosis or degenerative joint disease(DJD), is a progressive disorder of the joints caused by gradual loss of cartilage and resulting in the development of bony spurs and cysts at the margins of the joints.
Standard MRI shows cartilage defects that are irreversible," said Dr. Link. "The exciting thing about the new cartilage T2 measurements is that they give us information on a biochemical level, thus potentially detecting changes at an earlier stage when they may still be reversible.". People who have a higher risk for osteoarthritis can reduce their risk for cartilage degeneration by maintaining a healthy weight and avoiding risky activities and strenuous, high-impact exercise, according to Dr. Link.. "Lower impact sports, such as walking or swimming, are likely more beneficial than higher impact sports, such as running or tennis, in individuals at risk for osteoarthritis," he said.. Osteoarthritis is the most common form of arthritis, and affects more than 27 million Americans and over 100 million people worldwide. Osteoarthritis mainly impacts the hands, knees, and hips, and is the leading cause of disability in the U.S.. According to the Centers for Disease Control and Prevention, nearly one ...
Osteoarthritis pain impacts more than 21 million Americans. Its important to find effective ways to manage chronic osteoarthritis pain.
Osteoarthritis of the knee is a major cause of morbidity, physical limitation, and increased health care utilization, including total joint arthroplasty, among the elderly in developed countries. Because osteoarthritis has no cure, the important goal of therapy is to relieve pain and stiffness and maintain or improve physical function (1, 2). Nonpharmacologic therapy, which includes patient education, social support, physical and occupational therapy, aerobic and resistive exercises, and weight loss, is the cornerstone of a multidisciplinary approach to managing patients with osteoarthritis. Pharmacologic therapies for osteoarthritis of the knee include simple analgesics (such as acetaminophen); nonsteroidal anti-inflammatory drugs (NSAIDs), including cyclooxygenase-2 selective inhibitors; intra-articular therapy, including glucocorticoids and hyaluronate preparations; topical agents (such as capsaicin); nutritional supplements (such as glucosamine and chondroitin sulfate); and investigational ...
Objective We identified significant expression of the matricellular protein, DEL1, in hypertrophic and mature cartilage during development. We hypothesized that this tissue-specific expression indicated a biological role for DEL1 in cartilage biology. Methods Del1 KO and WT mice had cartilage thickness evaluated by histomorphometry. Additional mice underwent medial meniscectomy to induce osteoarthritis, and were assayed at 1 week for apoptosis by TUNEL staining and at 8 weeks for histology and OA scoring. In vitro proliferation and apoptosis assays were performed on primary chondrocytes. Results Deletion of the Del1 gene led to decreased amounts of cartilage in the ears and knee joints in mice with otherwise normal skeletal morphology. Destabilization of the knee led to more severe OA compared to controls. In vitro, DEL1 blocked apoptosis in chondrocytes. Conclusion Osteoarthritis is among the most prevalent diseases worldwide and increasing in incidence as our population ages. Initiation begins
Risk Factors for Osteoarthritis. There are several factors linked to the development of Osteoarthritis according to The National Institute of Health (NIH) these are:. Age - By reaching 45 or older raises your risk of degenerative arthritis.. Women - For unclear reasons, about 16 million women have osteoarthritis, out of a total of 21 million Americans who suffer from the disease. And though more men than women develop it before age 45, after that, degenerative joint disease becomes far more common in women.. Heredity - Genetic factors account for at least 50% of osteoarthritis of the hands and hips, and a smaller percentage in the knees. Certain inherited conditions such as being born with defective cartilage or malformed joints can also contribute to degenerative arthritis.. Obesity - People who are more than 10 pounds overweight have a higher risk for osteoarthritis, especially in weight-bearing joints like the knees. Pressure on joints from the excess weight causes cartilage to break down ...
Osteoarthritis (OA) is a chronic disease of the joint that results in degeneration of the cartilage and bone. However, in osteoarthritis, it is not uncommon to see intermittent or even chronic evidence of inflammation in the affected joint. Patients may experience stiffness after immobility (in the morning or after sitting for a long time), warmth and erythema of the joint, and soft tissue swelling and/or synovial effusion. On history taking and physical exam, these findings attest to the inflammatory nature of the involved osteoarthritic joint at the time. A microscopic examination of the synovium of patients with osteoarthritis will often show the presence of inflammation. Though cartilage and bone seem to be the primary targets of damage, it is likely that inflammation within the synovium may play an important role in the progressive damage to these joint tissues. Primary involvement of synovium may occur in some patients and secondary synovitis is commonly seen. This is associated with the ...
