Rottenstein Law Group Learns of DePuy ASR Hip Implant Failure Rate Much Higher Than Previously Reported

The Rottenstein Law Group has learned that DePuy’s ASR systems fail nearly half the time, a frequency much greater than previously publicized.

According to a recent Bloomberg article, “The British Orthopaedic Association and the British Hip Society said in a statement this week that data on the ASR XL Acetabular System from four surgeons show the rate of second operations, or revisions, ranges from 21 percent after four years to 49 percent after six years.”

The orthopedic surgeon who serves as chairman of the groups’ expert advisory group on metal bearing hips told Bloomberg that “about 10,000 of the hips were implanted in the U.K., including 5,000 or so resurfacing devices and 5,000 of the ASR XL prostheses, also known as total-hip replacements.”

“Based on the results presented, the use of large diameter metal-on-metal bearings in primary total hip replacement should be carefully considered and possibly avoided,” the U.K. group wrote, as quoted by Bloomberg.
DePuy, a Johnson & Johnson company, recalled its ASR devices globally after the National Joint Registry of England and Wales made public data showing that, within five years, about 12% of recipients of the hip resurfacing system and about 13% of recipients of the acetabular system needed corrective surgery—data that now appears to be out of date.

Two weeks ago, DePuy announced that David Floyd, president of DePuy since 2007, had resigned his position “to pursue outside interests.” Floyd will leave after a short transition period. No replacement for Floyd has yet been named.
