i had a partial knee replacement in 2007 . my luck it didnt work out because it came loose or didnt really hole ( the bone glue they used ) so i just had the partial revised to a total knee in october 2012.. I LOVE IT ... ITS TOTALLY PAIN FREE AS FAR AS THE ACTUAL KNE GOES . its just the long term of my nerves & muscles healing. i am really hopeful that this knee replacement is going to work out . i hope your knee replacement works out well . keep me posted
