More than 2,300 BioMet lawsuits have been filed by patients who allege that the company released defective hip replacements. The lawsuits, which have been consolidated in Indiana, focus on the BioMet M2a Magnum metal-on-metal hip replacement, which was found to fail at a rate much higher than other hip replacements.
Thousands of patients received the M2a Magnum hip implant since the device was approved by the Food and Drug Administration. Patients have complained of severe metal hip side effects, including premature loosening of the implant, tissue damage, corrosion and toxic levels of metal in the bloodstream.
Several companies have issued metal-on-metal hip replacement recalls since studies have showed the devices fail at a higher rate than alternative hip implants. BioMet has not yet issued an implant recall for the M2a Magnum, despite more than a yearly revision rate of 7.2%.
