Hi Herbie
Had a TKR (Total Knee Replacement) in October 2005. Op on the Friday at 11 a.m., back on the ward by 1 p.m., up walking with a frame at 5 p.m. !! I was 57 when I had it done. Don't get pains anymore, but you really do have to learn to walk again. A frien had the same op two weeks ago and he said the same. In the long run I think it's worth it. Couldn't drive for 8 weeks +, just couldn't press the brake pedal. Walking was no problem really, just remember not to limp and BEND the knee.
Good luck, keep us posted.
