Citing that “There is widespread concern regarding the incidence of adverse soft-tissue reactions after metal-on-metal (MoM) hip replacement” and “Recent National Joint Registry data have shown clear differences in the rates of failure of different designs of hip resurfacing,” a study by DJ Langton et al. (2011) aimed to “update the failure rates related to metal debris for the Articular Surface Replacement (ASR)” by DePuy Orthopaedics, Inc..
This study was titled “Accelerating failure rate of the ASR total hip replacement.” and appeared in the August 2011 edition of Journal of Bone and Joint Surgery.
For their study, the Langton et al. (2011) team studied a total of 505 DePuy ASR hips and found “a failure rate of 25% at six years for the ASR resurfacing and of 48.8% for the ASR total hip replacement (THR).”
The researchers note “Of 257 patients with a minimum follow-up of two years, 67 (26.1%)” had higher than normal serum cobalt levels and that “analysis of revised components showed that all patients suffering adverse tissue reactions in the resurfacing group had abnormal wear of the bearing surfaces.”
Sadly, DePuy Orthopaedics, Inc. failed time and again to warn users of the high rate of failure associated with the ASR and ASR XL models and in 2010, both of these metal-on-metal hip replacements were recalled. As a result of this failure to warn, however, a number of DePuy ASR lawsuits have been filed.
