Can osteoarthritis be prevented?

Research suggests that obese people are at risk of osteoarthritis and that weight loss can help prevent or delay osteoarthritis from occurring. This suggests that for anyone who is overweight, one benefit of a weight-loss program may help in the prevention of osteoarthritis.  Losing excess weight may prevent or lessen joint damage and decrease the stress on osteoarthritic joints. Being overweight puts extra strain on the joints, particularly the large weight-bearing joints such as the knees, the hips, and the balls of the feet. 

Exercise can help reduce joint pain and stiffness. Light- to moderate-intensity physical activity may prevent a decline in, and may even restore, health and function.   However, some people with osteoarthritis may be reluctant to exercise because of joint pain after activity. Various steps can be taken to help relieve pain, such as heat and cold therapy or taking pain relievers, which may make it easier for you to exercise and stay active. Choose partial or non-weight bearing exercise, such as bicycling, swimming, or water exercise

There is also an association between low intake of vitamin D and osteoarthritis. However, it is not known whether taking extra vitamin D can prevent this disease. Preventing trauma (for example, by wearing protective gear in athletic activities) also may prevent the development of osteoarthritis.
