I had a total knee replacement in mid May this year. I am down for both knees to be done. Since my operation I have been unable to walk due to the pain and instability in the knee of the unoperated leg. I was supposed to see the surgeon in Aug. then Sept. and now it has been put back again to mid October. I seem to be progressing o.k and only have some stiffness in the operated knee but I cannot get to physio as I literally can't stand up for more than a moment. I am at a loss and the tramadol and ibuprofen I am taking do nothing. Please has anybody any suggestions?
