WHAT IS OSTEOARTHRITIS (OA)?
Osteoarthritis, also known as degenerative joint disease, is the most common type of arthritis. Healthy knees are naturally filled with Synovial fluid that helps lubricate and provide cushioning. In osteorathritis the amount of synovial fluid is diminished and the joint space becomes more compressed. This causes the bones to rub together resulting in pain, swelling, and loss of motion of the joint. Although in some people it progresses quickly, in most individuals joint damage develops gradually over years.
