Zimmer knee replacement recall

As a Texas Zimmer NexGen knee recall lawyer, I am aware of the problems with this medical device. Knee replacement (also known as joint arthroplasty) surgery is a pretty common medical procedure which has increased quite a bit in the last few years. In 2003, Zimmer, Inc. brought out the NexGen CR-Flex Porous Femoral component. This medical device allowed a greater range of motion for patients than any other previous knee replacement device. The NexGen CR models should last about fifteen years. Unfortunately though, Zimmer has had a significantly higher than expected number of problems and complaints because of loosening and various other serious failures of its "cementless" knee replacement device model.

In fact, in 2007, a former Zimmer consultant teamed up with an orthopedic surgeon to make a study dealing with the reliability of the "cementless" NexGen CR-Flex Porous Femoral component. In 2010, this study was presented at a national convention of the American Association of Orthopedic Surgeons. The study showed that the knee replacement device failed at a quite higher rate than the average for the industry. This study showed that of the 108 Zimmer NexGen CR-Flex Porous Femoral components which were studied, 39 (36%) were loose and 10 (9.3%) had to be revised (which means a second surgery) or have to be revised because of loosening and pain.

 In September of 2010, Zimmer issued a recall for a specific tibial component of its NexGen knee replacement. It is important to note that Zimmer NexGen recall is only for a very specific component piece of the product. Although exact numbers are not known, it appears that the Zimmer NexGen knee replacement has been implanted in over 150,000 patients since 2003. The Zimmer tibial plate recall only concerns a fairly small number of persons who underwent knee replacement surgery since 2003. Many patients have already told their doctors that they have serious knee implant problems, such as loosening and dislocation of the device, ongoing severe pain, swelling and infection.

One issue is that, unlike some of the other Zimmer knee implants, the Zimmer NexGen CR-Flex does not use cement in the attachment process. This may cause the loosening, which causes horrible pain, swelling and difficulty walking. As such, these people may have to have a revision surgery to replace this Zimmer product with another implant.
