Have you suffered a failure after a Zimmer CR Flex Cementless Porous Femoral Head knee replacement surgery? Is revision or removal required?

 Lawsuit Information

In 2008, Zimmer Holdings, Inc., a medical device maker and considered a leader in the field of hip and knee replacements, issued a recall on its NEXGEN Complete Knee Solution MIS Total Knee System. MIS means minimally invasive surgery. The Zimmer recall occurred after the device appeared to potentially have broken during surgeries leaving fragments of metal in patients’ knees. Later, Zimmer clarified the recall by citing that the minimally invasive surgery (MIS) instrument was what was recalled not the knee implant itself.

Then, more recently, a study was published that suggested that this particular NexGen implant itself was failing at a high rate.  The publication was titled, “The High Failure Rate of a High-Flex Total Knee Arthroplasty Design”.

Minimally invasive total knee replacement involves a smaller incision of 4 to 6 inches as opposed to the longer incision of 8 to 10 inches. With a smaller incision, there is less damage to the tissue around the knee which can mean a shorter hospital stay, less recovery time, and less scarring. Although an artificial knee can be implanted through a smaller incision, doctors differ on their opinions as to whether or not MIS can be accomplished as well as longer incisions.

However, does this recent evidence now suggest that people who received the Zimmer NexGen MIS part in connection with a Total Knee Replacement of the tibia may be at increased risk of loosening or outright failure?  Further study and investigation may ultimately provide the answer to this question.

Product Identification Notice: In any of our web pages referring to Zimmer NexGen products, these pages are intended to provide information about and are referring to the same Zimmer products that were identified by Dr. Berger in his presentation and study entitled "The High Failure Rate of a High-Flex Total Knee Arthroplasty Design," and were written about in the NY Times article titled "Surgeon vs. Knee Maker: Who’s Rejecting Whom?," and that are reported in the FDA MAUDE database, where reports involving the Zimmer NexGen CR Flex Cementless or Porous Femoral component can be found and also those products associated with aseptic loosening of the Zimmer MIS Tibial Component that led certain doctors to discontinue its use, and to recommend discontinued use of this product in primary TKA until the etiology of the high early failure rate of this implant is determined. See prospective studies comparing the results of the Zimmer MIS Tibial Component using conventional and minimally invasive exposures as well as comparing fixation with different types of bone cement as described in Early Aseptic Loosening With a Precoated Low-Profile Tibial Component A Case Series. Not all Zimmer NexGen products are involved in our investigations and lawsuits.
