2012 – “Disapointing short-term results with the DePuy ASR XL”

Posted in DePuy Hip Replacement

Sadly, the 2012 paper by NM Bernthal et al., “Disappointing short-term results with the DePuy ASR XL metal-on-metal total hip arthroplasty.” lives up to its title.

This paper appears in the April 2012 edition of The Journal of Arthroplasty, and “reports on early failures of the ASR XL (Depuy, Warsaw, Ind) and assesses whether a correlation with cup positioning exists”, studying 70 consecutive metal-on-metal total hip arthroplasty procedures.

Of the seventy DePuy ASR XL hip replacements studied, a staggering 17.1% “required replacement within 3 years”.  The main reason for replacement was pain, but ASRs were also replaced due to loosening and squeaking.

“Three additional THAs noted squeaking, 2 noted grinding, and 3 additional hips had persistent pain” and “In total, 20 (28.6%) of 70 demonstrated implant dysfunction.”

Unfortunately, the team found that all problematic hips were in appropriate orientation, and “failures noted with this design do not correlate to cup placement.”  As such, the team concludes that “The high rate of implant dysfunction at early follow-up suggests serious concerns with the concept of MOM THA with an ultralarge-diameter femoral head paired with a monoblock acetabular cup.”

Due to the fact that DePuy failed time and again to warn users of the high rate failure associated with the ASR and ASRXL hip replacement systems, the DePuy ASR systems were recalled in 2010 and accordingly, a number of DePuy ASR lawsuits have been filed.
