I had a total knee replacement in 2008 and it has failed; pulled away from the bone. I am scheduled for a replacement on Dec 18.
Just adding this as an FYI, not knowing what implant she had installed. Certain Zimmer NexGen High-Flex knee replacement products have a high failure rate. Zimmer is involved in several cases of litigation; I am expecting paperwork from them to be added to their list of failed implants.
