DePuy Orthopaedics, Inc., Warsaw, Indianna, is voluntarily recalling the ASR™ XL Acetabular System and DePuy ASR™ Hip Resurfacing System used in hip replacement surgery due to the number of patients who required a second hip replacement procedure, called a revision surgery. 

According to the company, the majority of ASR hip replacement surgeries have been successful.  However, the company is advising patients with an ASR device to visit their surgeons for evaluation of their implant performance. Yearly monitoring is recommended to ensure the ASR hip replacement is functioning well, even in the absence of symptoms.

New, unpublished 2010 data from the National Joint Registry (NJR) of England and Wales shows a five-year revision rate of approximately 12% for the ASR™ Hip Resurfacing System and approximately 13% for the ASR™ XL Acetabular System.  These revision rates are across the entire size range. The risk for revision was highest with ASR head sizes below 50 mm in diameter and among female patients.  Previous post-market surveillance data from a variety of sources – including national joint replacement registries, published literature, company sponsored clinical trials, internal complaints data and unpublished clinical research reports – had shown lower revision rates and that the ASR hip was performing in line with other devices in its class.

DePuy intends to cover reasonable and customary costs of monitoring and treatment for services, including revision surgeries, associated with the recall of ASR.

DePuy is providing hospitals, surgeons and patients with comprehensive information about the recall to help them determine next steps. Patients and health care professionals with questions related to this recall should visit depuy.com. 

As of August 27, patients in the U.S. and Canada can contact DePuy by calling 888-627-2677 Monday-Saturday, 8 a.m. to 9 p.m. EST. 

The ASR device is part of a class of large diameter, monoblock hip resurfacing and replacement devices often selected by surgeons for younger patients who may benefit from a more stable device that can reduce the chances of dislocation after surgery.  The DePuy ASR™ Hip Resurfacing System was introduced in 2003 and is only approved for use outside the U.S.  The ASR™ XL Acetabular System was first launched in 2004 and has been available worldwide.
