Monitoring & Performance


As with all its products, the company closely monitored ULTAMET® Metal-on-Metal Articulation after it was introduced. DePuy reviewed performance data from a variety of sources, including published and unpublished data from national joint registries, published literature, company-sponsored clinical trials and internal complaint data.

The company continues to closely monitor the performance data for ULTAMET Metal-on-Metal and considers all available sources on an ongoing basis. Our ongoing monitoring of clinical data for ULTAMET Metal-on-Metal has continued to show a track record of reducing pain and restoring mobility for patients suffering from chronic hip pain, as noted below.


ULTAMET Metal-on-Metal is backed by a strong record of clinical data showing reduced pain and restored mobility for patients suffering from chronic hip pain.
