DePuy Hip Implant

DePuy Orthopaedics, a subsidiary of Johnson & Johnson, recalled two different hip replacement devices, known as the ASR XL Acetabular and the ASR Hip Resurfacing system, on August 24, 2010 after it was learned that they were more likely to fail within five years. The recall was initiated following a study showing that 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 than five years after they were implanted. The study also showed that many patients's receiving these hip implants suffered from severe pain, stiffness and swelling, followed by popping and grinding sensations which interfered with their ability to walk, stand or sit for long periods of time. 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 againsts 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.

Recently on June 28, the U.S. Food and Drug Administatrion advisory panel recommended that the labeling for mental-on-metal hip implants include warnings for tumor-like growths and elevated metal ion levels in the bloodstream.  The panel also stated that patients who have recieved metal-on-metla hips should be montiroired due to these risks. The FDA also foudn that there are few if any cases where they would recomend a replacement hip with metal-on-metal devices.
