DePuy Hip Recall Information
DePuy makes patient safety and health a top priority and is continually evaluating data about its products. The DePuyASR Hip is one of many hip replacements available from DePuy Orthopaedics. Most ASR hip replacement surgeries have been successful. However, data recently received by the company shows that more people than expected who received the ASR Hip System experienced pain and other symptoms that led to a second hip replacement surgery, called a revision surgery.
New data shows that five years after implantation, approximately 12% of patients (1 in 8) who had received the ASRresurfacing device and 13% of patients (1 in 8) who had received the ASR total hip replacement needed to have a revision surgery. For this reason, DePuy Orthopaedics is recalling its ASR™ XL Acetabular System and DePuy ASR™ HipResurfacing System.
This recall means additional testing and monitoring may be necessary to ensure your hip implant is functioning well. In some cases patients may need additional surgery. If you have received an ASR™ XL Acetabular System or DePuyASR™ Hip Resurfacing System, both of which will be referred to as your hip implant, the following information will help you understand what this ASR hip recall means to you and the steps you should take. Note: The DePuy ASR™ HipResurfacing System was only approved for use outside the U.S. and the ASR™ XL Acetabular System was available worldwide/ DePuy Hip Recall Attorney.
Tens of thousands of people have received the DePuy hip replacement and resurfacing implants. These devices have been associated with a 12%-13% failure rate, far higher than competing implants…]

Abstract
Metal-on-metal hip replacements are the subject of much current debate. There is some evidence that there may be a hypersensitivity reaction, specific to metal-on-metal total hip replacements (THRs), which is associated with early failure of these prostheses. It has to date only been described in total replacements and not in metal-on-metal hip resurfacing. We present the case of a 68-year-old man who underwent bilateral metal-on-metal hip resurfacing for osteoarthrosis. The patient presented 6 months after surgery with pain and lateral thigh swelling. Pre-operative ultrasound and MRI demonstrated findings similar to those described in early failing metal-on-metal THRs, as well as evidence of lymphoreticular spread of metal debris. The operative findings included extensive aseptic soft-tissue necrosis. Histology revealed necrosis and a dense perivascular lymphocytic infiltrate along with metal debris within sinus histiocytes. The surgical, radiological and histological findings are similar to soft-tissue reactions described in metal-on-metal THRs.
