Study: Total Hip Replacement Revision Rates 3% Higher for Metal-on-Metal Implants

Spinal Tech

Data released from the Canadian Institutes for Health Information show five-year revision rates for total hip replacement procedures to be low, though metal-on-metal implants bring slightly higher rates, according to The Windsor Star. The study found patients with common metal-on-plastic hip implants had a revision rate of 2.7 percent, while those with large diameter metal-on-metal implants had a 5.9 percent chance of needing replacement within five years.

Metal-on-metal replacements made up 9 percent of the procedures studied. However, Canadian physicians tend to be more conservative with their use of metal-on-metal implants, according to the report. In the U.S. in the late 2000s, 45 percent of men with hip replacements had metal-on-metal devices.
