dave, its nice of these folks to give you encouragement. But let's be truthful. I am 9 weeks out from a complete knee replacement. Dave, it a s.o.b. Swelling, pain and walking well still a challenge. I can climb stairs but it is painful. I am finally able to sleep most of the night and getting up only to pee. Getting in my truck is still a challenge. My doctor has x-rayed it twice since surgery and everything looks correct. I have attended 12 pt sessions and do home exercises when I am able. We will see as time goes on as most people say it takes 6 months to a year to see real improvement but right now I would not do it again.
