You're waiting on the hospital? Took me 10 months from when my surgeon and I booked to get my first one done, did the exercises they tell you to do and all is coming around fairly quickly. Went in for my 6 week check up on February 1 and we booked my left, March 28 I get my left one done. I have went sledding since my first one was replaced and got close to 300 miles this year. Next year should be a good one. Good luck with your knee replacement.
Personally I have not experienced this, but my cousins wife did. She went from crutches and pain to walking completely normal,it really was amazing. She had both knees done. You'll be riding like nothing happened next year.
I've raced and always rode really hard. Yes my first couple rides were more of a feeling out, but by next fall I expect I should be riding pretty much the way I did before. Only thing is probably think first in some situations because if you screw it up you will explode it out of the bone as the implant won't break.
