A FIX FOR YOUNGER HIPS

Three years ago, at the age of 50, John Michalek of Lakeview, N.Y., was frustrated and in pain. Both his hips were giving out, victims of early onset arthritis, likely due to an inherited bone structure that produced bad biomechanics. He considered a total hip replacement. But his surgeon urged him to wait. The implants last only 10 to 20 years, which meant Michalek would be looking at another replacement in his sixties or seventies.
