A 30-month prospective study of nearly 3000 adults has discovered that even less than 1/4 inch of difference in leg length nearly doubled the risk of osteoarthritis. It is estimated that up to 70% of the population have one leg shorter than the other. This study strengthens the evidence that unequal leg length is a cause of osteoarthritis and its progression. For people with very small leg length differences, corrective treatment with shoe inserts or modifications may be helpful.
