What happens to articular cartilage in arthritis?

So, you want to know What happens to articular cartilage in arthritis?

During the development of osteoarthritis (OA), the normal, quiescent chondrocytes become activated and undergo a phenotypic shift, resulting in fibrillation and degradation of cartilage matrix, the appearance of chondrocyte clusters, increased cartilage calcification associated with tidemark advancement or duplication, …

Does articular cartilage degeneration in rheumatoid arthritis?

Destruction of articular cartilage is a common feature of OA and RA, and comparing the disease processes directly is an important—but challenging—task. OA is considered a degenerative joint disease, in which cartilage damage results from the intrinsic activity of the embedded chondrocytes.

How is a joint damaged in rheumatoid arthritis?

Rheumatoid arthritis is an autoimmune disease. This means that your immune system – which usually fights infection – attacks the cells that line your joints by mistake, making them swollen, stiff and painful. Over time, this can damage the joint itself, the cartilage and nearby bone.

Is rheumatoid arthritis Characterised by degradation of articular cartilage?

Rheumatoid arthritis (RA) is a polyarticular joint disease. The inflammatory process is characterized by infiltration of inflammatory cells into the joints, leading to proliferation of synoviocytes and destruction of cartilage and bone.

What happens to articular cartilage in arthritis Related Questions

What is the most common form of arthritis that affects the articular cartilage?

Osteoarthritis (OA) is a painful condition involving the deterioration of the cartilage inside your joints. Affecting 32 million people in the United States, it is the most common arthritic condition.

What causes inflammation and degeneration of the articular cartilage?

One of the primary causes of articular cartilage damage is injury to the joints, especially the knee joint and hip joint. Injuries, especially if they are not treated properly, can accelerate natural degeneration of articular joint cartilage and amplify the effects of daily wear and tear.

Does RA damage cartilage?

Rheumatoid arthritis (RA) is a chronic inflammatory disorder that leads to symmetrical polyarthritis characterized by synovial inflammation, cartilage destruction, and bone erosions [1, 2].

What are the articular complications of rheumatoid arthritis?

Rheumatoid arthritis (RA) can present extra-articular manifestations (ExM) and comorbidities such as infections, cardiovascular events, and malignancies, which have been associated with increased morbidity and mortality.

What are the articular manifestations of rheumatoid arthritis?

local swelling, redness and pain. stiffness following inactivity. characteristic deformities of the hand and wrist. extra-articular manifestations, for example, rheumatoid nodules, Sjogren’s syndrome, pleurisy, vasculitis, peripheral neuropathy.

What is the most affected joints in rheumatoid arthritis?

The joints most often affected by RA are in the hands, wrists, feet, ankles, knees, shoulders, and elbows. Symptoms may include joint pain, stiffness, and swelling; decreased and painful movement; bumps over small joints; and fatigue or fever.

What part of the synovial joint is damaged in rheumatoid arthritis?

What happens to joints affected by rheumatoid arthritis? Rheumatoid arthritis (RA) results in inflammation of the joints and, in particular, the synovial membrane that covers them (synovitis). An overproduction of synovial fluid occurs, which causes joints to swell and the capsule to stretch, causing pain.

What is the cause of bone fusion in joints damaged by rheumatoid arthritis?

Progressive inflammation from RA can destroy the cartilage and bone around affected joints. Severe loss of cartilage can lead to bones becoming deformed and fusing. This can cause the joint to become immobilized.

What damaged articular cartilage?

Articular cartilage injuries can result from a number of causes, including: Forceful impacts to the joint as a result of sports injuries or a fall. Repetitive smaller impacts to the joint. Twisting the joint while it bears weight, for instance twisting the knee while the foot is planted.

What causes degradation of articular cartilage?

The progressive destruction of articular cartilage is one of the hallmarks of osteoarthritis and rheumatoid arthritis. Cartilage degradation is attributed to different classes of catabolic factors, including proinflammatory cytokines, aggrecanases, matrix metalloproteinases, and nitric oxide.

What type of cartilage is damaged in arthritis?

The main component of the joint surface is a special tissue called hyaline cartilage. When it is damaged, the joint surface may no longer be smooth. Moving bones along a tough, damaged joint surface is difficult and causes pain. Damaged cartilage can also lead to arthritis in the joint.

What is the most common extra articular manifestation of rheumatoid arthritis?

Nodules are the most common extra-articular feature, and are present in up to 30%; many of the other classic features occur in 1% or less in normal clinic settings.

What is the articular cartilage damage by osteoarthritis characterized by?

Osteoarthritis is characterized by clinical symptoms of joint pain and aching, limited range of motion and instability, radiographic evidence of the erosion of the articular cartilage joint space, narrowing sclerosis of the subchondral bone and osteophytes (spurs).

In which joint disease the main pathogenesis is loss of articular cartilage?

Osteoarthritis (OA) is the most common debilitating disease, a leading cause of disability, and is characterized by chronic pain and whole arthropathies such as articular cartilage damage, synovitis, subchondral bone remodeling and osteophyte formation.

Which autoimmune disease can damage cartilage in synovial joints causing arthritis?

Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by inflammatory arthritis and extra-articular involvement. It is a chronic inflammatory disorder caused in many cases by the interaction between genes and environmental factors, including tobacco, that primarily involves synovial joints.

What is degeneration of the articular cartilage in a joint?

Articular degeneration, commonly known as osteoarthritis (OA), is the most common joint pathology of aging and occurs over time. Characterized by joint space narrowing, osteophytes, swelling, morning pain and stiffness, and eventually joint deformity, articular degeneration can be accompanied by muscle weakness.
