Ditto, Mac!! Only my pain dated back 15 years coupled with back pain related to the way I had to walk to try to ease the pain. Had my total knee replacement 2 years ago this coming August and, like you, why oh why didn't I do it sooner. My other knee is not a bother as of yet so I'm lucky there. Everything you said is true. For those of you who are considering a replacement I offer this advise. DO YOUR EXERCISES following surgery. Yes, they are painful but each day it gets a little better and you'll be so happy down the road that you did.
