BioMet UK has issued a warning to surgeons not to perform surgery for its knee replacement medical device after discovering the components do not fit together. The company said that if a surgeon were to begin surgery with the device, it would not be able to be completed.
BioMet is also facing scrutiny for its M2a Magnum metal-on-metal hip replacement, which has been found to fail at a rate much higher than other metal hip implants. A 2011 study in the Australian National Joint Registry found that 7.2 percent of devices would require revision surgery.
Manufacturers are facing metal-on-metal hip replacement lawsuits after many patients have complained of hip replacement side effects. BioMet M2a magnum side effects include metallosis, premature loosening of the hip, limited mobility and pain.
