Recall and Regulation of the DePuy ASR Hip

The majority of hip replacement surgeries are completely beneficial to patients with a success rate of about 98%. So starting around 2008, when a large influx of failure reports surfaced, many doctors and researchers were surprised. The staggering majority of the reports were from patients who had received the DePuy ASR Hip System. DePuy Orthopaedics is a division of Johnson & Johnson. The ASR Hip System was released in the United States for medical market use starting in 2005. Both the ball and socket are manufactured with a cobalt and chromium alloy. This hip implant was the first of its kind to use these metallic materials for total hip replacement surgery.

The DePuy ASR was recalled by DePuy Orthopaedics in 2010 after a staggering amount of data confirmed the high failure rate of the implant. Many people experienced extreme discomfort within the first five years that the hip was installed. When undergoing an arthroplastic surgery like a total hip replacement, doctors are liable to make mistakes like misaligning the ball and socket. This misalignment can cause unnecessary wear to the implanted material as well as post-operative dislocation of the joint. However, many people that suffered as a result of being implanted with the DePuy hip experienced pain because of the product’s defective design, not medical negligence. Because the product’s design is flawed, there have been hundreds of lawsuits filed by individuals who have been hurt due to faulty implants.

Many doctors and researchers mention that the metallic material of the implant is not conducive to the surrounding sensitive tissue. As the muscle and tissue surrounding the acetabulum and femoral head heals from surgery, it can often be aggravated by the DePuy ASR metal shavings. The cobalt and chromium technology can increase metal ion levels in the patient’s bloodstream. Patients that have been fortunate enough to not need numerous surgeries after injuries related to the DePuy ASR are encouraged to make annual appointments with their orthopaedic physician in order to measure blood levels and check on the condition of the hip implant.
