In 2011, a paper titled “Early failure of articular surface replacement XL total hip arthroplasty.” in The Journal of Arthroplasty by GD Steele et al., stated “The ASR (articular surface replacement) XL (DePuy, Warsaw, Ind) metal-on-metal hip arthroplasty offers the advantage of stability and increased motion. However, an alarming number of early failures prompted the evaluation of patients treated with this system.”
As such, attempting to determine the rate at which DePuy ASR XL hip replacements fail and require revision (replacement) surgery, Steele et al. (2011) studied 95 patients (105 hip replacements) over a minimum of two years each and analyzed what they found.
At the end of the study, it was found that 16 revisions had been required. Researchers write “Thirteen (12%) were aseptic acetabular failures. Eight were revised for aseptic loosening; 4, for metallosis; 1, for malposition; 2, for infection; and 1, for periprosthetic fracture.”
Concluding, Steele et al. (2011) write “The ASR XL with a revision rate of 12% is the second reported 1 piece metal-on-metal system with a significant failure rate at early follow-up” and “This particular class of implants has inherent design flaws that lead to early failure.”
With the publication of studies such as this, demonstrating a failure rate significantly higher than that reported by DePuy, a number of DePuy ASR lawsuits have been filed. If you or a loved one used an ASR hip replacement, you too may be entitled to significant financial compensation.
