Clinical Follow-up of ASR Patients Post-Recall
DePuy Orthopaedics has issued a voluntary recall of the ASR hip replacement system due to a
higher than expected revision rate reported in the England/Wales and Australian national
joint registries. There are two types of ASR hip implants used for total hip replacement
surgery:
- ASR XL Hip System
- ASR Hip Resurfacing System Massachusetts General Hospital (MGH) in Boston, USA is the
study sponsor. MGH is conducting this study with the help of funding from DePuy
Orthopaedics. MGH will collect and analyze clinical information from 5,000 subjects
around the world. The countries include the United States of America, Australia, South
Africa, England, Denmark, Finland and Sweden. MGH will collect and analyze blood test
results, X-rays, soft tissue imaging and how well the ASR hips are functioning. MGH will
analyze the data annually for 6 years.
The purpose of this study is to follow patients who have the ASR hip system for the next 6
years. The findings of this study may help surgeons to make better informed decisions about
monitoring and treatment of patients with ASR hip systems.
