The National Joint Registries in the United Kingdom and Australia released their Annual Reports. Both reports show that the DePuy ASR and DePuy Pinnacle metal-on-metal implants perform poorly and both have caused a significantly increased rate of revision surgeries compared to other total hip implants.
More than 1/3 of DePuy ASR Implants Have Failed After 7 Years
The UK Registry shows that after 7 years, 37 percent of DePuy ASR hip implants have failed and been revised. The report shows a steady increase in failure rates starting at 7.5 percent at only 3 years.
Likewise, the Australian Registry shows that the ASR fails at a rate of 37 percent at 7 years and 43 percent at 9 years:
The Australian Registry shows that the ASR hip implant fails at a rate more than 800% higher than other total conventional hip implants.
DePuy's Pinnacle Metal-on-Metal Implants Fail At A Rate That's 3 Times Higher Than Polyethylene Implants
The United Kingdom Registry provides a direct comparison of DePuy's Pinnacle hip implants when it is used with a polyethylene liner (MoP) as compared to a metal liner (MoM). This direct comparison shows that the metal-on-metal version of the Pinnacle fails at a rate more than 360% higher than the the Pinnacle metal-on-polyethylene implants.
