2013 – Study shows DePuy ASR failure rate 14.9% at 5 years

Posted in DePuy Hip Replacement

In a paper titled “Hip arthroplasty with the articular surface replacement (ASR) system: survivorship analysis and functional outcomes.” published in European Journal of Orthopaedic Surgery and Traumatology, the authors begin by stating “The articular surface replacement (ASR) hip resurfacing system, now withdrawn, has the highest all-cause revision rate (24.2 % at 7 years) compared with other resurfacing brands.”  As such, the DePuy ASR has prompted many lawsuits.

This medical research team, led by one S. Shemesh, “reviewed the medical records and examined all 55 patients (57 hips) who had THA by the senior author between March 2005 and November 2008” and “recorded the Oxford Hip scores, metal ion levels, need for revision, the indication for revision, and the intra-operative findings” for each patient.

This team found that after five years, the survival rate for the ASR implants was 85.1%; that is, 14.9% of the metal-on-metal hip replacements failed at five years – a dramatic increase in failure rate over that disclosed by DePuy.

“At the time of recall, 10 (17.5 %) of fifty-seven THAs were already revised. Four (40 %) of the ten revisions were performed within 1 month of the operation due to a periprosthetic fracture. Three other revisions were due to avascular necrosis at a mean time of 3.6 years. One patient was revised due to infection. The two remaining revisions were due to ongoing groin pain, in one of whom the cup was found to be loose.”

Due to the fact that DePuy disclosed a failure rate for its ASR/ASRXL hip replacement systems significantly lower than that reported by independent researchers, a number of DePuy ASR lawsuits have been filed.
