Hi, I had a TKR on 23rd Oct '21. The physio who i see at the hospital is threatening an MUA because as yet I haven't quite achieved 90 degree bend. Nor can I fully straighten my leg. I had an accident 25 years ago which led to my recent TKR, so on and off I have limped for about 5 years and have muscle atrophy. The leg extensions my physio is trying to get me to do where my knee is lay over a pipe are almost impossible. Same with sitting on a chair with my leg at 90 degree's, its quite painful behind the knee. I've been told I need to be at 100 degree's by next Tue. I simple can't bend it that far at the moment without force. I feel like I'm falling behind her expectations and twice now she has mentioned MUA......I'm scared!
