DePuy ASR XL Acetabular System implants and DePy ASR Hip Resurfacing System implants have been found to have an unreasonably high failure rate, requiring many patients implanted with the DePuy hip to undergo revision surgery for a second hip replacement procedure.
DePuy Hip Update 1/23/13: Newly disclosed court documents have revealed that a 2011 internal investigation conducted by Johnson & Johnson on its much-troubled DePuy ASR hip implant estimated that the device would fail within five years in nearly 40% of recipients. For reasons still unclear, the company failed to make this information public while simultaneously downplaying the potential health complications associated with its metal-on-metal hip.

What the DePuy ASR Acetabular Cup Is, and Why It Fails
The DePuy ASR Acetabular Cup System is a metal-on-metal hip component used in traditional hip replacement in the United States. The ASR hip resurfacing system, which is used in a popular alternative to traditional hip replacement, has not been approved in the U.S. but has been used abroad.
DePuy ASR acetabular cups are forged out of cobalt chrome. Physicians and their patients have discovered that, after being used even short periods of time, the rubbing of metal-on-metal in the artificial joint starts to cause the cobalt and chrome ions to escape and disperse to nearby parts of the body. When these ions relocate, they can infiltrate organs, produce local irritation, or even create cysts. Doctors have reported encountering these large cysts during revision surgery, having them break open and leak their contents.
In addition to metallic debris, the device design may also result in elevated friction between the femoral head and the acetabular cup, creating more initial friction during leg movement than other similar implants. The elevated friction is then transferred through the acetabular cup out of the junction between the acetabulum and the acetabular cup. This problem is of particular importance immediately after the surgery — the worst time to be experiencing unnecessary friction in the cup.
