DePuy ASR Metal-on-Metal Hip Replacement Problems

What the DePuy ASR Acetabular Cup Is, and Why It Fails

The DePuy ASR System is a large diameter, "metal-on-metal" hip replacement prosthetic. The acetabular cup (made of metal) rests on and moves directly against the femoral head (also metal).

This design has been shown to cause problems that necessitate early revision surgeries. In addition, ASR hip implant recipients have presented with elevated levels of cobalt and chromium ions in their bloodstream.

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.
