In 2015, Zimmer settled multiple lawsuits related to its NexGen knee implant for approximately $1 billion. The claims alleged that the NexGen knee implants failed prematurely, causing pain, instability, and the need for revision surgeries. Many patients filed lawsuits citing the implant’s design flaws, specifically the faulty femoral component. The settlement resolved claims for thousands of individuals who suffered complications due to the defect.
