Zimmer Knee Implants & Device Failure

Zimmer NexGen CR-Flex Knee Implant Linked to Risk of Loosening and Failure

Knee problems can be debilitating. A knee injury or the sudden onset of a health disorder can make once healthy adults immobile: Athletes who are no longer able to run, parents who are no longer able to play with their children, and men and women in the prime of their lives who suddenly find themselves feeling disabled.

A knee replacement can seem like the answer to their prayers. This surgery represents a chance to get full mobility again - to return to the way of life that these patients had known before their injury. Yet, for some patients who received the Zimmer NexGen CR-Flex knee implant, the surgery signaled the beginning of even more debilitating pain and the need for more surgery.

The Facts: Zimmer NexGen CR-Flex Knee Implant

  • The Zimmer NexGen CR-Flex knee implant was introduced in 2003, and it has since been used in more than 100,000 patients.
  • Two surgeons - one who worked as a consultant to Zimmer - presented data at a March 2010 conference of the American Academy of Orthopedic Surgeons that the failure rate for the Zimmer NexGen CR-Flex Porous Femoral Component could be as high as 9 percent, and that loosening occurred in 39 percent of patients.
  • These two surgeons urged a recall of the Zimmer NexGen CR-Flex Porous Femoral Component.

Zimmer NexGen CR-Flex Porous Femoral Component

The Zimmer NexGen CR-Flex Porous Femoral Component is a non-cement piece that caps the femur (the thigh bone) at the point where it connects to the tibia at the knee. Unlike traditional knee implants, it is made of a porous metal and does not attach to the bone with cement.

Studies have shown that the Zimmer knee implant is at higher risk of loosening or detaching over time. Two surgeons from Rush University Medical Center - Dr. Craig Della Valle and Dr. Richard Berger, who also worked as a consultant for Zimmer - presented research at the March 2010 conference of the American Academy of Orthopedic Surgeons that the component had to be replaced in about 9 percent of patients within two years. Loosening was found in 39 percent of patients in the same time frame.

Knee replacements are intended to last approximately 15 years. Dr. Berger described the failure rate of the Zimmer knee implant as "unacceptably high," and both doctors urged Zimmer to recall the product. Zimmer has not recalled the product, and it has blamed the failure rates on the poor surgical technique of the doctors rather than any defects in the implant.
