Zimmer NexGen Knee Replacement Systems

Zimmer NexGen Knee Replacement Systems

Several components of Zimmer NexGen knee replacement systems have been linked to a high number of problems, including reports of pain, loosening of the implant and failure of the replacement knee leading to revision surgery.

In March 2010, data was presented by a group of knee surgeons that indicates 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 the replacement knee loosening.

In September 2010, recalls were issued for several components due to apparent manufacturing defects or design defects. The FDA issued a Class 2 recall related to certain Zimmer knee replacement components, including the MIS Stemmed Tibial component and specific lots of the NexGen LPS Femoral Component and the NexGen LPS Flex Gender Femoral Component.  The Zimmer NexGen MIS recall covered over 68,000 knee components following at least 114 reports of problems that caused some individuals to experiencing loosening of the parts or the need for additional knee surgery. The Zimmer NexGen LPS recall was issued due to nonconfirming and inconsistent geometry.

It is suspected that the higher-than-expected failure rate is linked to design problems with Zimmer NexGen replacement knees, as the orthopedic surgeons concluded that they were not caused by surgical errors, problems with the techinque or the type of patient who received the knee implant.

More than 150,000 Zimmer NexGen CR and Zimmer NexGen CR-Flex Porous Femoral implants have been sold since 2003, and some doctors have reported experiencing a substantially higher-than-expected failure of the replacement knee within a few years of surgery.

The Zimmer replacement knee is a “high-flex” component, which attaches to the bottom of the thigh bone. Unlike most knee replacement systems, the Zimmer NextGen knee does not use a cement surgical to hold the implant in place. This may be a design defect which increases the risk of a knee replacement loosening and the need for additional surgery to revise the implant.
