Rheumatoid arthritis (RA) is the most common type of autoimmune arthritis.
A chronic inflammatory disorder affecting many joints, including those in the hands and feet.
Rheumatoid Arthritis (RA) affects joints on both sides of the body (both knees, both hands or both wrists). Over time, Rheumatoid Arthritis (RA) can cause wearing out of cartilage, leading to swelling in the synovium and excess fluid in the knee.
Most commonly, the wrist and hands are involved, with the same joints typically involved on both sides of the body.
