Overweight patients who have early signs of osteoarthritis or who are at high risk should be encouraged to lose weight. Recommend quadriceps-strengthening exercises in patients with osteoarthritis of the knees, except in those with pronounced valgus or varus deformity at the knees. (See Lifestyle Modification, Physical/Occupational Therapy, and Other Nonpharmacologic Measures.)

It has been proposed that low vitamin D levels may play a role in the development and progression of osteoarthritis; however, studies of vitamin D status and osteoarthritis have produced conflicting results. [147, 148]

A systematic review found no convincing evidence that selenium, vitamin A, or vitamin C is effective for the treatment of osteoarthritis. [149] A prospective cohort study also found no evidence that vitamin C supplementation slowed the progression of knee osteoarthritis; however, it did find that patients who reported taking vitamin C were 11% less likely to develop knee osteoarthritis. [150]
