Arthritis - Cause

Spotlight

Osteoarthritis occurs when changes in cartilage cause the cartilage to break down faster than the body can produce it. When cartilage breaks down, the bones rub together and cause damage and pain. Experts don't know why this happens. But things like aging, joint injury, being overweight, and genetics may increase your risk.

In some cases, arthritis is caused by other conditions that damage cartilage.
