Metal-on-Metal Hip Implants Have Higher Fail Rates

Study: All-Metal Hip Replacements Fail Faster Than Other Types

Patient Advice

Jacobs says patients with metal-on-metal implants should return to their surgeon for regular checkups, even if they aren’t having any problems.

Patients who are having pain or difficulty walking or moving should see their doctors immediately.

Other experts think the issue is more urgent.

“We have half a million patients who have metal-on-metal hips in the U.S. We need to focus investigation on this issue,” says Art Sedrakyan, MD, PhD, an orthopedic surgeon at Weill Cornell Medical College in New York.

Sedrakyan wrote a commentary on the study but was not involved in the research.

Based on this study and mounting evidence against metal-on-metal designs, Sedrakyan says use of the implants should stop.

“The risk is too high to continue to use metal-on-metal implants,” he says.

WebMD contacted Zimmer and DePuy, two manufacturers of metal-on-metal implants, for comment on the study. WebMD also reached out to an industry group that represents medical device manufacturers, the Medical Device Manufacturers Association. They didn't respond to requests in time for publication.
