Failure Rates High In All Metal On Metal Hips Implants
A new study published in The Lancet finds that high early failure rates of metal-on-metal hip implants are not limited to one design or manufacturer, but rather may be related to the entire class of devices.
Less surprising news is that the data from the world’s largest joint replacement registry show that all-metal hip implants have early failure rates that are two to four times higher than implants made with ceramic or plastic parts.
The study, which analyzed data from the National Joint Registry of England and Wales, tracked more than 31,000 metal-on-metal replacement hips implanted in patients in the U.K. between 2003 and 2011. The registry also includes information on more than 371,000 hip systems made from other materials.
The study excluded the DePuy Orthopaedics ASR implants
