Zimmer NexGen CR-Flex Porous Knee Litigation

Comments Off

Some Zimmer NexGen knee replacement systems have been linked to reports of pain, loosening of the implant and failure of the replacement knee leading to revision surgery. These cases are being reviewed by Zimmer NexGen knee lawyers, who are evaluating the damages for individuals who have experienced problems after a Zimmer knee replacement.

Several different components used as part of Zimmer NexGen knee replacement systems have been associated with a potential increased risk of problems, which may result in pain, limited range of motion, loosening of components or the need for additional revision surgery. In March 2010, data was presented by a group of knee surgeons that indicates nearly 9% of patients who received the Zimmer NexGen CR-Flex Porous Femoral component required revision knee surgery within two years and 36% showed signs of the replacement knee loosening.

At a conference of the American Academy of Orthopaedic Surgeons in March 2010, several prominent knee surgeons presented data on the outcomes of 108 knee replacement patients who received the Zimmer NexGen CR-Flex Porous Femoral component at Rush University Medical Center in Chicago.

After only two years, the researchers reported:

* 9 patients required knee revision surgery due to loosening and pain
* 39 patients showed evidence of radiographic loosening

It is suspected that the higher-than-expected failure rate is linked to design problems with Zimmer NexGen replacement knees, as the orthopedic surgeons concluded that they were not caused by surgical errors, problems with the techinque or the type of patient who received the knee implant.

More than 150,000 Zimmer NexGen CR and Zimmer NexGen CR-Flex Porous Femoral implants have been sold since 2003, and some doctors have reported experiencing a substantially higher-than-expected failure of the replacement knee within a few years of surgery.

The Zimmer replacement knee is a “high-flex” component, which attaches to the bottom of the thigh bone. In most knee replacement systems, a type of surgical cement is used to hold the implant in place. But, the Zimmer NextGen knee does not use a cement and this may be a design defect which increases the risk of a knee replacement loosening and needing additional surgery to revise the implant.

As a result of recalled Zimmer knee replacements and potential problems with the design for certain NexGen components, thousands of individuals may have been exposed to an increase risk of early failure. A number of individuals throughout the United States are pursuing compensation through a Zimmer NexGen knee replacement lawsuit as a result of the manufacturer’s failure to adequately research the artificial knee system or warn about the risk of Zimmer knee problems.
