Surgeons blame design flaw caused high failure rate in DePuy Hip implants

DePuy Orthopaedics recalled the ASR XL Acetabular Systems total hip replacement and the ASR Hip Resurfacing System in 2010 after studies showed that 12to 13 percent of patients had a failure rate which required another replacement in only five years after their hip replacement. This amount accounts for 12 to 13% of the total number of hip transplant patients.

DrugWatch reports that physicians and orthopedic surgeons believe that the faulty design of the DePuy hip implant is the cause of the high failure rate. Surgeons point to the design of the hip cup specifically saying that it was designed too shallow which which results in edge-loading where the hip implant ball rubs against the cup’s edge, causing metal debris to be rubbed off, releasing metal ions of cobalt and chromium, causing a condition called metallosis.

Hip implant registries in Australia and Great Britain alerted Depuy in 2008 of high failure rates when compared with other company’s hip implant devices yet DePuy continued marketing the implant in the U.S.
