More Revisions of THRs with Metal on Metal than Other Devices
The Orthopedic News Network estimated that about 460,000 people had hip replacements in 2010, and approximately 56,000 of those were revisions. Because hip replacements are on the rise in people under 60 (reports the Huffington Post and BBC News in 2016) doctors predict more hip revision surgeries.
Data from the Orthopedic Registry in both Australia and the United Kingdom indicate that only five percent of patients who receive total hip replacements require revision surgery within seven years. But 15 percent of metal-on-metal implant recipients in the U.K. registry and 8 percent in the Australian registry required revision surgery within seven years.
Dave’s Stryker Rejuvenate revision surgery has similar rate of failure. According to the Encyclopedia of Surgery, 13 percent of patients who had a Stryker hip had complications within two years and had revision surgery to remove the device. About eight percent required an additional revision surgery.
Sharon had the Biomet’s M2a Magnum hip implant. Nearly 14 percent of Biomet Recap M2a Magnum hip replacements caused complications that required revision surgery, according to a 2013 study by The Department of Orthopaedics and Traumatology, Turku University Hospital, Finland.
But only 4 percent of patients received revision surgery by the time of a 2015 study, which may indicate that many surgeons are no longer using metal-on-metal hip replacements due to high failure rates. Perhaps those predictions are wrong…
