Consumer Alert Update: Zimmer NexGen Flex Knee Implants Litigation

Robins, Kaplan, Miller & Ciresi is currently litigating Zimmer NexGen Flex Knee Implant claims in the MDL in Illinois.

April 20, 2012

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.

Bone Joint Surg. 1457 (2007); Sung-Do Cho, et al., Three- to Six-year Follow Up Results After High-Flexion Total Knee Arthroplasty: Can We Allow Passive Deep Knee Bending?, 19 Knee Surg. SportsTraumatol Arthrosc. 899 (2011). Note that not all Zimmer NexGen knee products have shown a high failure rate. Products of particular interest are those that are "Flex" or "High-flex" products.
