Study Sheds Light On Metal Hip Replacement Failure Risks
A new study on metal hip replacement failure and revision surgery finds age and gender to be risk factors to hip replacement failure rates. Patients who are male and relatively young at the time of initial implant are more likely to need revision surgery, according to the study conducted by scientists at Brigham and Women’s Hospital and Harvard Medical School.
Researchers analyzed Medicare data on patients who received hip replacements to treat osteoarthritis between July 1995 and June 1996, and followed up participants for the next 12 years to determine risk factors for revision surgery.
Approximately two percent of patients underwent revision surgery per year for the first 18 months, which fell to one percent per year for the rest of the follow-up period. Men were 23 percent more likely to require revision surgery than women.
Age also had an impact on revision surgery rates. People who received the initial hip replacement aged between 65 and 75 were 47 percent more likely to undergo revision surgery than those over 75.
In addition, surgeons who performed fewer than six hip replacements per year had a higher risk of revision surgery than surgeons who performed more than 12 operations a year.
Increasing concerns about high revision surgery rates have led patients, doctors and researchers to question the use of metal hip systems. In 2010, DePuy Orthopaedics issued a worldwide recall of its DePuy ASR hip implants after data showed that one in eight of the hip replacement devices failed a few years after surgery. The U.S. Food and Drug Administration has received nearly 17,000 adverse event reports about metal-on-metal hip systems, including 14,121 reports of patients who had to undergo revision surgery, which is often an extensive and painful process.
Patients who received metal hip systems and experienced complications or hip replacement failure are filing lawsuits to seek compensation for their injuries, including medical expenses, lost wages, pain and suffering, and more.
