The Stryker Rejuvenate and ABGII hip implant devices were recalled last July, 2012, following a significant number of adverse reports from consumers, sent to the FDA. Over 20,000 of the devices were sold in the United States following FDA approval for the two models in 2008 and 2009, and it is believed that the majority of these were implanted into patients. Stryker sent out an urgent field safety notice just months before the recall, notifying doctors and hospitals that the Rejuvenate and ABGII were more likely to suffer fretting and corrosion which could lead to the release of metal ions, failure of the hip device and the risk of metal toxicity.
