Almost three years after DePuy’s hip replacement recall, a new scientific study from Finland reports a shockingly high failure rate of 62 percent for some sizes of the recalled hip implant.
Dr. Aleksi Reito and his colleagues at Coxa Hospital for Joint Replacement in Finland implanted over 1,000 ASR hip implants between 2004 and 2009. In a retrospective study, the doctors examined the performance of patients who received smaller diameter ASR implants (with a head size less than 50mm.) They found that after 7 years, a shocking 62 percent of the ASR total hip replacements had failed and had to be surgically removed. About half of those patients suffered adverse reactions to metal debris, a diagnosis that is commonly associated with the ASR hip implant.
In a secret internal document, DePuy determined that 37% of ASR hip implants in the United States had failed after only 4 1/2 years. DePuy refused to release this information to doctors or patients, and it even fought in Court to prevent the data from being disclosed to the public.
Although 7-year data is not yet available in the United States, we anticipate that the failure rate in the United States will be as bad (if not worse) than the results reported out of Finland. And, unfortunately, we expect that DePuy will do everything it can to ensure that these failure rates are never reported to doctors or patients.
