Both of my sisters in law had knee replacements, one about 7 years ago and the other 4 years ago. I know that both had a lot of pain, but neither has regretted having the operation done, their quality of life is so much better now. I can recall the one hobbling around with two canes before the operation; now she takes long walks every day. Hang in there, Joe, the pain will only last for a little while, then you will have your life back.
