Zimmer NexGen Knee Replacement Linked To Alleged Failures

At the March, 2010 conference of the American Academy of Orthopedic Surgeons, two knee surgeons reported implant surgery findings of the Zimmer NexGen knee replacement system, according to the organization’s site. Of those surgeries, the site reports that 36 % of those implants were loose while 9.3% “had revision or impending revision for painful loosening.” Of those 146 surgeries the pair of doctors detailed at the conference, 108 were shown to have some form of complication later.

Despite these findings, The New York Times explains that Zimmer refutes claims that that their products are unsafe. According to the New York Times, the manufacturer blames surgical technique for the failures, not the actual devices. The Times also reports Zimmer said in a statement it “welcomed the opportunity” to discuss doctor concerns. 

According to the Times article, the company explained that the “feedback can lead to modifications and improvements to products,” including the way they “train and educate surgeons.”  The Times reports this statement was in reaction to a letter Senator Charles E. Grassley’s sent to the maker of the NexGen knee replacement system.

In that letter, the Times reports that he asked “the nation’s biggest maker of artificial hips and knees,” Zimmer Holdings, “to disclose information about how it handles complaints about possible product flaws from its medical consultants.”  

According to the American Association of Orthopedic Surgeons website, this implant utilizes a “cementless high-flex femoral component” and it “has a high incidence of failure of osseointegration.” Although many of these “modern cementless femoral components” have been successful, the site explains, this product’s future success was taken for granted and “was introduced to the market without clinical testing.”

While traditional knee implants connect to the patient’s thighbone with cement, Zimmer’s system does not use this adhesive, according to the American Association of Orthopedic Surgeons website. The site explains that this particular “component is still commercially available but should not be used for any patient.”
