150,000+ Zimmer NexGen CR and Zimmer NexGen CR-Flex Porous Femoral implants have been sold since 2003. Recalls were issued in September 2010 for several NexGen components due to defects. A Zimmer NexGen MIS recall was issued for more than 68,000 knee components following reports of patients experiencing loosening of the parts, or the need for additional knee surgery. A Zimmer NexGen LPS recall was also issued due to non-confirming and inconsistent geometry.
These recalls came after data presented by knee surgeons in March 2010 indicated that nearly 9% of patients who received the Zimmer NexGen CR-Flex Porous Femoral component required revision knee surgery within two years and 36% showed signs of loosening in the replacement knee.
There are several components used as part of Zimmer NexGen knee replacement systems that have been associated with a potential increased risk of problems – resulting in pain, limited range of motion, loosening of components, and the need for additional revision surgery.
We would like to review any cases where a Zimmer NexGen replacement knee device has caused discomfort; including pain, limited range of motion, or loosening of components. Also, any individuals who are unsure of the type of knee replacement device implant they may have received or anyone who has had a revision surgery.
