According to a new study published in the British Medical Journal (BMJ), no matter the type of material, all artificial hip replacement devices appear to work the same. In fact, the purported revolutionary new metal-on-metal hip implants have been shown to be no more effective and sometimes even more problematic than much older models. Thousands of lawsuits have been filed nationwide on behalf of individuals allegedly injured by hip implant devices.
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.

Hip Implant Recall Update 7/10/12: Michigan-based Stryker Orthopaedics is now recalling two brands of devices used in conjunction with artificial hips in hip replacement surgeries. To date, the devices in question – the Stryker Rejuvenate and ABG II Modular-Neck Stem – have been linked to at least 45 adverse event reports (AERS) submitted to the FDA by individuals who claim to have suffered severe pain and/or tissue swelling.

What’s the problem?
November 29, 2011 – Dr. Art Sedrakyan, lead researcher in the new study, has stated that there is a great deal of evidence suggesting that higher rates of replacement surgery are associated with metal-on-metal hip implants compared to their metal-on-polyethylene counterparts.
“Metal-on-metal and ceramic-on-ceramic hip implants might not be associated with any advantage, compared with traditional bearings such as metal-on-polyethylene or ceramic-on-polyethylene,” said Sedrakyan, who is director of the Patient-Centered Comparative Effectiveness Program at Weill Cornell Medical College in New York City.
Sedrakyan ultimately believes there have not been enough scientific studies conducted on artificial hip devices to make a conclusive determination as to whether one type is better than the other.
“There are very successful implants on the market today for hip replacement,” Sedrakyan said. “We need to have stronger data on improvement in clinical outcomes for new hip implants,” he said.
Each year, nearly a half million people undergo hip replacement surgery around the country, a small percentage of which have the procedures to fix problems with previous hip devices. These procedures are typically performed about a decade after the initial surgery because of infection, dislocation, wear, instability, or loosening of the implant. The average cost of surgery is between $35,000 and $40,000, with the newer metal-on-metal devices being substantially more expensive.
Later model hip replacement devices constructed with metal-on-polyethylene or ceramic-on-polyethylene surfaces have been reported to have lower overall failure rates compared to newer models. Additionally, metal-on-metal hip prosthetics have been associated with instances of metal ion accumulation in patients’ tissues.
In 2009, the FDA initiated a cumulative review of the overall safety and effectiveness of artificial hip implant devices.
Sedrakyan’s research team investigated various artificial hips in 18 studies, including more than 3,000 patients and nearly a million operations. The researchers concluded that there was essentially no difference between the devices when it came to patients’ quality of life or overall ability to perform everyday tasks.
