Suspected Avascular Necrosis in a Runner
December 31, 2006
A 34-year-old man has had bilateralknee pain for the past 16 months andbilateral hip pain for the past 8 months.The pain is exacerbated by running, byweight bearing, and recently even by sittingfor extended periods. Moving froma sitting to a standing position is especiallydifficult. A week earlier, he visitedan urgent care center and was given naproxen and a 7-day course of prednisone,but neither medication alleviatedthe pain; in fact, he now feels worse.
