Unlike osteoarthritis, Rheumatoid knee arthritis involves inflammation of the lining of the joints, known as the synovium. Though less common than osteoarthritis, rheumatoid arthritis is among the most debilitating of the over one hundred forms of arthritis. Rheumatoid arthritis usually develops in middle age, but may occur in the 20s and 30s.
Rheumatoid Arthritis of the Knee
Causes
The exact cause of rheumatoid arthritis is unknown. It’s possible that a virus or bacteria may trigger the disease in people with a genetic predisposition to rheumatoid arthritis. Many doctors think rheumatoid arthritis is an autoimmune disease in which the tissue of the joint’s lining is attacked by the body’s immune system. It’s also possible that rheumatoid arthritis is caused by severe stress. The disease sometimes occurs after a life-changing event such as divorce, loss of a job or a severe injury.
