Thousands got Exactech knee or hip replacements. Then, patients say, the parts began to fail

Irby is one of more than 1,100 patients suing Exactech after it began recalling artificial knees, hips, and ankles, starting in August 2021. A letter Exactech sent to surgeons blamed a packaging defect dating back as far as 2004 for possibly causing the plastic in a knee component to wear out prematurely in about 140,000 implants. Many patients argue in hundreds of lawsuits that they have suffered through, or could soon face, challenging and risky operations to replace defective implants that failed.
