Information About Legal Rights Pertaining to ASR XL Acetabular System
DePuy Orthopaedics—a subsidiary of Johnson & Johnson—recalled its ASR XL Acetabular System and ASR Hip Resurfacing System hip replacements in August 2010 due to an increased risk of complications among patients who had received these . Researchers found that one in eight patients with ASR total hip system required surgery within five years of implantation to correct problems with DePuy hip replacements.
DePuy launched the ASR XL Acetabular System in July 2003. The device was designed to replace the socket portion of the hip that connects it with the femur. During surgery, a femoral stem is inserted into the femur and attached to a metal-lined ball, which is inserted into the hip bone. These components are then aligned by a surgeon, allowing the device to function like a normal hip joint.
In the years prior to the DePuy recall, a number of scientists had warned of the increased potential for problems with “metal-on-metal implants” such as the ASR XL Acetabular System. In addition to warnings about the health risks of metal-on-metal implant—which include severe inflammatory reactions and damage to muscles, tendons and other soft tissue—some experts believed that a design flaw in the ASR hip replacement system was causing it to fail only a few years after it was implanted.
After the Food and Drug Administration received approximately 300 complaints involving patients who had received ASR implants, DePuy announced plans to eventually phase out sales of the device. But after data from researchers in the UK showed that patients with the ASR XL Acetabular System were more than twice as likely to required repeat surgeries than patients who received other devices, the company announced that it would recall the device in the U.S.
Patients who underwent hip replacement surgery after July 2003 and who received a DePuy ASR XL Acetabular System have been advised to speak with their surgeon in order to check for potential problems with the device. In addition to a physical examination, your doctor may also order blood tests or imaging scans in order to ensure that the device is not issuing metal debris and does not require replacement surgery.
