The DePuy ASR hip implant–which was the subject of a worldwide hip implant recall in 2010–is failing at an even higher rate than before according to a report published by the National Joint Registry for England and Wales.
The National Joint Registry, which tracks the hip implants in England, just released its 2012 Annual Report. This report is based on failures that were reported as of the end of 2011. The newly-published report shows that the DePuy ASR hip implant is failing at an even higher rate than at this time last year.
In the 2011 NJR report, 17% of the ASR hip implants had failed after only five years. In the 2012 report that was just published, the five-year failure rate increased to 22%. To put that into perspective, of the 90,000 patients who had the defective ASR hip implanted in their bodies, 20,000 likely will need to undergo a complex, painful, and risky surgery to remove the implant after just five years.
In reality, we believe the failure rate is much higher than the 22% reported in the NJR report. Many hospitals around the world have reported an even higher failure rate. For example, at one center in England, the failure rate is at least 49% at five years. At a 49% failure rate, more than 44,000 patients will need to undergo a revision surgery after five years.
Despite the staggering rate of failure of the ASR implant, the only failure rate that DePuy discloses to patients and doctors on its website is a five-year failure rate of 13%. By providing this outdated information, we believe DePuy is intentionally trying to prevent patients and doctors from knowing the true rate at which its defective hip implant is failing.
