Dr. Richard Berger, a Chicago surgeon who was a long time user of Zimmer implants, has urged the manufacturer to recall some of its artificial knee implants, reports the New York Times.
Dr. Berger was a long-time consultant to Zimmer on its products. He began experiencing premature failure of the Zimmer NexGen CR-Flex Porous Femoral knee replacement. A 2010 study indicates that the failure rate after only a few years may be as high as 9%. The study reveals that 36% of patients implanted with the Zimmer NexGen CR-Flex Porous show signs of implant loosening after only 2 years.
Zimmer has responded by criticizing Dr. Berger’s surgical technique, which is interesting, because over the years Zimmer has paid Dr. Berger almost $8 million to lecture and train surgeons in how to use and implant this and other Zimmer products.
To date, Zimmer has refused to order a recall. However, litigation is underway against Zimmer for these high failure rates. If you have a Zimmer knee implant and have experienced knee stiffness, knee pain, diminished motion in the joint, difficulty with weight bearing, have been told that your implant is loose or that you need a revision, you may have a claim against Zimmer for this defective product.
