Having gotten through another year I am happier now with my knee replacements than I was a year ago. Getting my shoes built up has helped a great deal and serious rehab helps. I am still unable to walk at any clip but I sat on an air plane long enough to get from Little Rock to Glasgow without any pain, and that is something I simply could never have managed pre-arthoplasty. Still I would recommend waiting as long as possible. It's no picnic.
