OSTEOARTHRITIS CAUSED BY OVERUSE

A study from the university of Washington shows that young female professional dancers are at high risk for joint damage presumably because they have to keep on exercising , even when they hurt (1). This supports many other studies that show the competitive athletes are at high risk for osteoarthritis (2,3,4,5).

The very high incidence of permanent joint damage in former athletes, and lower incidence in non-athletes (6), should serve as a warning to you when you exercise. If your muscles or joints start to hurt, stop exercising and don't try to resume exercising until you can exercise without pain. Fortunately, you are not likely to lose your job if you stop exercising.

If you try to exercise through pain, you can break cartilage that can never heal. Surgery to remove broken cartilage may increase your chances of needing a knee replacement in the future (7,8), particularly if you continue to run and jump. Repeated cortisone-type injections can weaken cartilage and cause further damage (9,10,11,12). Nonsteroidal pain medications do not prevent further damage. Weak thigh muscles increase chances for further knee damage (13). so all people with knee damage should strengthen the muscles that control their knees with special knee machines (14) and start a supervised program of cycling or swimming, provided that it does not hurt to do them.
