Defective Zimmer NexGen CR-Flex Knee Replacement Systems
There is a growing body of evidence linking the Zimmer NexGen CR-Flex knee replacement system to defects that result in serious pain, implant loosening, and implant failure. More than 150,000 patients have received the device as part of a knee replacement operation since 2003.
The main issue associated with this defective medical device is caused by a design flaw in its cementless attaching system. This has created problems with osseointegration, the process where the implant fuses with the surrounding bone structure.
A recent study conducted by Dr. Richard Berger and Dr. Craig Della Valle provides considerable evidence that the Zimmer NexGen CR-Flex knee replacement system places patients at a high risk of post-surgical problems. The two orthopedic surgeons presented their research to the American Association of Orthopedic Surgeons in March 2010.
According to the study, the Zimmer NexGen CR-Flex knee replacement system experiences a 9% failure rate within two years. Most knee replacement systems should last approximately 15 years. Patients experiencing knee replacement failure required revision surgery to correct the problem. Furthermore, approximately 36% of patients experienced implant loosening resulting in considerable pain.
While the Zimmer NexGen CR-Flex knee replacement system remains on the market, many orthopedists, including Dr. Berger, believe it should not be used with patients. If you have suffered an injury from using the Zimmer NexGen CR-Flex knee replacement system, you may be entitled to receive compensation for your damages.
