Zimmer NexGen CR-Flex Porous Femoral components and Zimmer NexGen LPS-Flex artificial knee replacements have been associated with high incidences of significant pain and loosening of the replacement knee, leading to the failure of the knee replacement, revision knee surgery or other knee surgery complications.
In March 2010, data was presented by a group of prominent knee surgeons indicating nearly 9% of patients examined after two years required revision knee surgery and 36% showed signs of loosening of the cement-less CR Flex artificial knee. These failure rates are higher than expected and are believed to be due to design defects. Based on the high number of calls we have received, we believe other models of the Zimmer NexGen artificial knee may also be defective and will ultimately be recalled.
On July 29, 2010 Senator Charles Grassley (R-Iowa) issued a letter to Zimmer Holdings regarding problems with certain models of the Zimmer NexGen knee replacement system, indicating that the Senate Finance Committee was investigating the product’s safety.
- Loosening Popping
A study published in the American Academy of Orthopaedic Surgeons Conference in March, 2010 documented the high failure rate of the high flex (CR Flex) total knee design, and studies as early as 2007 have discussed the high incidence of loosening of the NexGen LPS Flex knee replacement system.
