The Zimmer NexGen Knee replacement system is failing, and as a result, thousands of patients must undergo revision and replacement surgeries. A former Zimmer orthopedic consultant has reported that the Zimmer NexGen Knee replacement problems resulted in revision surgery in nearly 9% of patient cases. Knee replacement loosening was reported in more than a third of the cases.

Zimmer Knee Replacement or Repair Systems

• Zimmer NexGen CR Flex Total Knee Replacement (TKR)
• Zimmer NexGen LPS Flex TKR
• Zimmer NexGen Gender Solutions High Flex TKR
• Zimmer MIS (minimally invasive surgery) Tibia Stem (AKA the short keel tibia tray)

Zimmer Introduced in 2003, the NexGen CR-Flex system. The Zimmer NexGen CR-Flex system is a synthetic device used to cap the thigh bone (femur) where it connects with the tibia at the knee. Unlike traditional knee implants, the Zimmer Nex-Gen CR-Flex Knee is made of a porous fiber metal and a cobalt-chromium-molybdenum alloy and is not attached using cement.

Since Zimmer Nex Gen CR-Flex Knee was brought to market, more than 150,000 of the NexGen implants have been sold, and new data suggests that while they were originally projected to last around 15 years, a large percentage have failed in three years or less. This past March 2011, the results of a study were presented at an American Academy of Orthopedic Surgeons conference that indicated that 36 percent of NexGen patients examined after two years showed signs of the replacement loosening. The same study, conducted by Dr. Richard Berger and Dr. Craig Della Valle, both surgeons at Rush University Medical Center in Chicago, also found that nearly 9 percent of Zimmer Nex-Gen CR-Flex Knee patients examined after two years required revision knee surgery due to loosening and pain.

One problem that has been reported with the NexGen Knee Implant concerns the fact that its “high-flex” component is not surgically cemented to the bottom of the patient’s thigh bone. Most knee replacement devices are secured with surgical cement to prevent loosening, which may explain the NexGen’s high failure rate. To date, no FDA Zimmer NexGen Knee Recall has been announced.
