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 risk for revision was highest with ASR head sizes below 50mm in diameter and among female patients.

With the recall of ASR, DePuy intends to cover reasonable and customary costs of monitoring and treatment for services, including revision surgeries and is providing hospitals, surgeons and patients with comprehensive information about the recall to help them determine next steps.

DePuy Orthopaedics president David Floyd said that they regret that this recall will be concerning for patients, their family members and surgeons and are committed to assisting patients and health care providers by providing information through multiple channels and paying for the cost of doctor visits, tests and procedures associated with the recall.
