Osteoarthritis

Osteoarthritis (OA) is the most common form of arthritis. In fact, more than 75 percent of people older than fifty-five show joint deformations of OA on X-rays. But most of these people have no symptoms. For people who do have joint pain and stiffness of OA, it can become a crippling disease. Some people suffer from OA in just one joint, while others have it in several joints. It affects more women than men, and most OA patients are over 45.
