In June the opened up my knee on the same scar for the 3rd time. All sutures were removed. Had to immobilize my knee at first since surures were holding tissue together so lost 10 degree of bend. No bumps showing under my skin. Feels like my knee was freed, like the sutures were hindering my movement. No more pain but will always be stiff. At least I can walk normally and sit with my knees bent. Had to wait a complete year to have sutures removed in order to allow tissues to heal from all the scar tissue that was removed during my revision. It was worth getting sutures removed.
