Recently, doctors have urged the FDA to recall the Zimmer NexGen knee replacements for failure rates higher than expected. In 2010, reports disclosed that approximately 9% of people with the Zimmer NexGen CR-Flex Porous Femoral component knee replacement required a revision surgery within two years. In addition, 36% of patients reported a loosening of the knee replacement. These problems are attributed to the design of the device which Zimmer reportedly did not test in patients before selling it.
In September 2010, various parts of a specific model of the Zimmer NexGen knee replacements, the Complete Knee Solution MIS, were recalled. However, Zimmer failed to issue any press releases and the FDA failed to issue any alerts regarding this recall. The recall occurred after numerous complaints against Zimmer NexGen were brought to the attention of the FDA. Although the Zimmer NexGen device in its entirety has not been recalled, class action lawyers are investigating the higher-than-expected failure rates for these artificial joints.
The Zimmer NexGen knee replacements have been implanted in nearly half a million people since its introduction. It is reported to last about 15 years before an additional replacement is necessary. Most knee replacements require the use of a cement that keeps the knee in place but the NexGen does not use this adhesive, which is possibly the cause of these frequent defects.
