The Stryker Rejuvenate hip implant was recalled by Stryker in July, 2012 after numerous reports came in to the FDA regarding symptoms of metal toxicity and metallosis among recipients. Stryker cited a higher-than-normal rate of failure due to the likelihood of fretting and corrosion, leading to excess metal ion debris generation. The design of the Stryker Rejuvenate was considered extremely innovative at the time it was released. After many recipients of all-metal hip implant devices suffered significant health problems, the ceramic ball of the Rejuvenate was believed to be a safer alternative with fewer risks of metal ion shear

The DePuy Pinnacle metal hip implant is the same monoblock type of implant as DePuy’s ASR however has a few key differences. Of course the primary difference is that the ASR was recalled in 2010 while the Pinnacle is still on the market. Because of the recall of the ASR—which gained FDA approval based on being substantially equivalent to the Pinnacle—there are serious concerns regarding the Pinnacle as well. The Pinnacle received FDA approval in 2000, howevermany orthopedic experts believe that not only does the Pinnacle suffer from a defective design; it also has a propensity for early failure rates and metal toxicity.
