According to the results of a new study, more than three-quarters of all metal-on-metal hip replacement failures occur within two years of being implanted. The vast majority of these complications are caused by aseptic acetabular loosening, which often requires painful revision surgery to correct. Over the past several years, an increasing number of metal-on-metal hip recipients have reported problems with their implants, including device failure and other issues caused by microscopic metal particles that are released as parts of the implant rub together.
DePuy Hip Update 1/23/13: Newly disclosed court documents have revealed that a 2011 internal investigation conducted by Johnson & Johnson on its much-troubled DePuy ASR hip implant estimated that the device would fail within five years in nearly 40% of recipients. For reasons still unclear, the company failed to make this information public while simultaneously downplaying the potential health complications associated with its metal-on-metal hip.

What’s the problem?
July 19, 2012 – The study, which was published in this month’s edition of the medical journal Orthopedics, included a review of 80 patients who underwent corrective surgery to remove failed metal-on-metal hip replacements. The researchers found that 78% of the recipients had the surgeries within two years of being implanted with the devices, and 98% had the artificial hips removed within the first three years of surgery. Metal-on-metal hips were originally designed to last between 15 and 20 years.
The study also found that 13% of the patients who required revision surgery also suffered from localized soft tissue reactions, which most experts believe is caused by metal components rubbing against each other, a condition known as metallosis. The new research adds to the growing body of evidence that has uncovered fundamental flaws with metal-on-metal hip replacement systems. In June, an independent advisory panel to the U.S. Food & Drug Administration (FDA) advised anyone who was been implanted with one of the devices to get annual x-rays to check for problems. The panel also recommended that recipients suffering from pain and discomfort should undergo a test to look for signs of elevated levels of metal in their bloodstream, a key indicator of metallosis.
Over the past two years, sales of metal-on-metal hip replacement devices have dropped sharply, as more research has focused on the long-term effects of metal particles in the blood. In August 2010, Johnson & Johnson issued a recall for DePuy ASR hip implants after acknowledging that up to 15% of the devices were failing within the first five years. Since the recall, thousands of lawsuits have been filed in courthouses around the country alleging that the company failed to adequately research the design or warn the public about the potential for failure.
In addition to the claims filed over the DePuy ASR hip implant, similar issues have been raised over other metal-on-metal hip replacement devices including the DePuy Pinnacle, Biomet M2A-Magnum, and the Wright Profemur artificial hip. As the number of lawsuits filed over these products continues to mount, serious questions remain about the safety of any artificial hip device that features direct metal-on-metal contact that bears the weight of the body during normal daily movements.
