I had TKR of right knee 1/2/23. While i was in preop i was ready to get up and hobble away because I had heard o any bad stories. Thankfully I went thru with the surgery and I am now very happy 5 months later.
Do your preop exercises so you are strong after surgery. Then of course do your post op exercises. Of course it hurts when exercising, but it’s not unbearable. You should come thru it well.
