Consumer Alert Update: Zimmer NexGen Flex Knee Implants Litigation

The Zimmer NexGen Flex knee replacement system, manufactured by Zimmer Inc., is marketed as a line of "high-flex" knee implants designed to give knee replacement recipients greater range of motion.[1] However, studies have shown that these high-flex implants can lead to pain, loosening, and instability in the knee, requiring removal and replacement of the implants.[2]  Our firm is currently litigating these claims in the MDL in Illinois.
