Well, I sure am sorry you didn't have "perfect" results, Pax. Riding a bike sounds icky, when you put it that way!
I know my step-father had a close-to-perfect result in the first knee but a much less good in the second, so you truly never know. A lot of it has to do with your particular anatomy, of course. When my step-dad came back after his second knee surgery, he said that the surgeon called it "interesting". Not something you really want to hear wrt your surgery!
