About Osteoarthritis Knee Pain

Learn about osteoarthritis of the knee

Osteoarthritis (OA) is a common degenerative joint disease that affects an estimated 27 million Americans. Of those 27 million, over 10 million people experience it in their knees, making OA of the knee the most prevalent form of OA. It is a chronic disease in which the cushioning tissue, or cartilage, in the knee joint wears away and the thick fluid that helps lubricate the knee joint, called synovial fluid, becomes thinner and less effective. When the deterioration of cartilage becomes severe, the bones grind together, leading to friction and causing pain and stiffness.1-3
