I had a TKR on JUNE 25, 2019, I had twenty sessions of PT and was doing well making good progress. I had to stop the PT and have been trying to do the exercise on my own for the past seven months. flexion and extension are causing a great deal of issues. It is hard to walk up and down stairs, my right heel is drawn up, probably because of tight tendons or scar tissue. Has anyone else experienced this issue. I sure do not want to go under anesthesia for knee manipulation. Hopefully I can do free leg hanging exercises with weight attached to my knee for better extension. Any good advice will help.
