Hi to all! I have struggled with my TKR. February 2019. I have good range of motion and good stability. Still a lot of pain which leads to it still being weak. Painful on stairs and uneven surfaces. Still pain at night a lot of swelling and now a lot of grinding on flexing of the joint, especially from sitting position with weight on it. Just saw surgeon and he wants to open the knee back up and remove scar tissue. Not arthroscopic! Full reopening of the knee. Am going to get a second opinion of course but wondering if any have had this sort of experience? Thanks for your help!
