DePuy Hip Replacement Recalls
DePuy Orthopaedics recalled two hip replacement devices in August 2010 after it was learned that they were more likely to fail within five years. According to researchers, about one in eight patients who received DePuy’s ASR XL Acetabular System or ASR Hip Resurfacing System required surgery to have the devices replaced less that five years after they were implanted.
The DuPuy hip recall came just months after the company announced that it was “phasing out” the two devices due to low sales. Patients who received the devices have suffered complications including fractures around the site of the implants, loosening or dislocation of the devices and metal debris from the device that may spread into the blood stream.
A number of health experts have stated that DePuy should have issued the hip replacement recall earlier after reports emerged that the devices were failing at a higher than normal rate. Doctors estimate that 5% of patients that undergo hip replacement surgery will require “revision surgery” to correct problems with their device within five years. By contrast, 12-13% of patients who received one of the recalled DePuy implants required repair surgery in five years or less.
Several hip replacement specialists have stated that the problems with DuPuy hip replacements may have been caused by design problems with the devices. Some hospitals reported that they stopped performing hip replacements with DePuy implants well before the recall was issued due to problems they had observed with the devices.
Lawsuits filed against DePuy and its parent company, Johnson & Johnson, have alleged that the two companies knew about problems with the DePuy hip replacements for at least two years before the recall. Although the Food and Drug Administration received at least 400 reports of problems with DePuy hip implants in the two years before the DePuy hip recall, the company waited for months after concerns about the products became widespread among some experts before taking them off the market.
