Update: Zimmer NexGen Knee Implant Litigation

August 17, 2012

Reports of high levels of failure associated with certain types of Zimmer’s® NexGen® Flex Knee replacements [1]  have led to hundreds of lawsuits being filed against the device manufacturer alleging the early failure of these knee systems.[2] These cases have been consolidated into a Multi-District Litigation (MDL).  This means that all cases in federal court alleging that these particular NexGen® products caused injury are now centralized before one judge in the Northern District of Illinois (Chicago).[3] Currently, nearly 500 cases are pending in the MDL. The first bellwether trial, which is like a test case, is expected to commence in Spring of 2014.[4]

Robins, Kaplan, Miller & Ciresi L.L.P. is currently litigating and investigating potential claims on behalf of patients implanted with or injured by the Zimmer® NexGen® Flex knee. If you or a loved one believe you may have received one of the Zimmer® NexGen® Flex knee replacements and are experiencing problems with it, please feel free to contact our offices at 1-800-553-9910.
