Evidence for increased bone resorption in patients with progressive knee osteoarthritis: Longitudinal results from the Chingford study

Our data demonstrate that bone resorption is increased in patients with progressive knee OA and is not increased in those with nonprogressive knee OA. The increase in bone resorption seen in patients with progressive knee OA is similar to that observed in patients with osteoporosis. Altered bone turnover may be a diagnostic or therapeutic target in patients with progressive OA.
