I had knee replacement in Aug 2011. Dont have much motion and still in pain. So they r going to straiten knee all the way and bend knee all the way back break up scar tissue while im sleep. I had a very hard time w pain after first surgery because of tolerance to pain meds. I heard this was very painful and p.t. is important everyday after surgery. First day! Im still waiting on pain management doc. My doc has helped but cant continue. The whole reason had surg was to decrease pain and meds. Im depressed and only 34 yrs old. Frustrated!
