Hi, I seem to be stuck around 90 degree ROM following tkr surgery 20 weeks ago. I went to PT for two months and have been doing post op stretches and exercises daily. I’ve had constant swelling ever since the surgery and recovery has been very slow because of it. I’ve also had several prior surgeries on the same knee so figure scar tissue is at least a big part of the problem. I was wondering what options are available to me without doing a MUA? Any thoughts or suggestions?
