Some patients with all-metal hips — ones in which the cup and ball of a joint is made of metal — said they had been bounced from doctor to doctor who did not have the knowledge or the tools to properly diagnose the problem. And by the time they reach specialists like Dr. Kwon at Massachusetts General Hospital, potentially lasting damage may have already taken place.

Dr. Kwon’s recent patient, Robert Cartier, said he saw seven doctors over the course of a year who told him not to worry or who gave him shots for his pain. Diagnostic tests also did not point to a problem. Only recently have researchers determined that such scans need to be run in a specific way to detect the extent of metal-related damage.
