Zimmer Next Gen Knee Replacement


The Zimmer replacement knee is a flexible component which is attached at the bottom of the thigh bone.  Most knee replacement procedures use a cement that is specifically designed for surgeries to hold the component in place.  The Zimmer Next Gen is unique in that it does not use a cement to bond it in place.  This could be a design flaw that apparently increases the likelihood of the device loosening in place and eventually could lead to additional surgery to remedy the problem or even replace the device with a different brand of component altogether.  Researchers have presented data to the American Academy of Orthopaedic Surgeons in March 2010 on the results after two years of 108 knee replacement surgeries using the Zimmer Next Gen.  Almost 10% of patients required knee revision surgery due to loosening, swelling, and pain.  39 patients showed evidence of radiographic loosening.  This data ruled out the possibility of surgical error and problems that might otherwise have been associated with the patients themselves.  The problems appear to be related to design flaws in the Zimmer Next Gen Knee Device.

Patients have complained of the following complications following the Zimmer Next Gen Knee replacement surgery: tenderness; severe and increasing pain; inability to walk; a knee that is inflamed or hot to the touch; swelling; grinding, rubbing, cracking, and popping noises and sensations, and increasingly limited mobility or joint movement.

Patients considering knee replacement surgery would do well to study their options and consult with a trusted physician before electing to use this particular device.
