Nearly 40% of DePuy hip replacements will fail within five years, J&J study finds

by Heygood Orr and Pearson

A study conducted by Johnson & Johnson shortly after the company recalled two models of its DePuy hip replacements found that the implants would fail within five years for 40% of patients who received one of the two devices. Johnson & Johnson recalled the DePuy ASR XL Acetabular System and ASR Hip Resurfacing System hip replacements in August 2010 after studies revealed that the implants were more likely to fail prematurely than other hip replacements.

The documents which revealed the existence of the Johnson & Johnson study about the side effects of DePuy hip implants were uncovered by attorneys representing hip replacement patients in a lawsuit against DePuy and Johnson & Johnson. More than 10,000 DePuy lawsuits have already been filed by patients who have experienced problems with one of the recalled ASR hip replacements.

The two DePuy ASR hip replacements that were recalled by Johnson & Johnson are metal-on-metal hip replacements which use a metal cup and ball combination. According to warnings by the Food and Drug Administration, because they can shed metal particles into the body that can cause broken bones and other problems, metal-on-metal hip replacements may be more dangerous for patients than other hip implants that do not use an all-metal combination.

Although thousands of patients have already undergone revision surgery to correct problems with a faulty DePuy hip replacement, experts have predicted that many more patients may require surgery within a few years as they begin to experience problems with a DePuy implant that is still in their body. Patients who experience hip replacement problems in the future may wish to speak with a DePuy lawyer to determine if they are eligible to file a hip replacement lawsuit.
