@johnbishop : I will try to find those kind of knee pads. Would also come in handy around the house, I think (for such pleasant tasks as cleaning behind the toilet on a tiled bathroom floor - have tried that a few days ago, did not feel good at all!). Good luck with your surgery in the spring. I hope it gives you as much improvement and pain relief as the TKR did for me, short-term discomfort (!) as they call it, and endless exercises notwithstanding.
