Having these procedures done is all about quality of life. Being in constant, burning pain brings life down to the level of mere existance, and I also wondered if it was worth it once in a while. Having two kids and great wife keeps one from doing anything rash or stupid, though, and I now I can look forward to a life of positives. I, too, am an ex-roadracer, and I'm mulling over the possilibty of doing track days again. Jeez, I'm not too sure just how it's gonna fell to be able to actually move around on the bike in the corners. Most of my time on the track has benn in the classic "knees in, toes out" riding style of the 60's. Putting the right knee out was simple horrible. Not any more. You have my undying respect for having a bi-lateral procedure done. What I've gone through so far ihas been a relative piece of cake, and having both done at once looks like a real challenge. Good on you for having such a fantastic outlook for what's in store!! Life is what we make of it, and I've seen far too many people give up in the face of pain, sickness, or hardship. We only get one go around, and it's really gratifying to see that others here are sharing my opinion that making the best of it is really the only option. BTW, Larry Pegram, an American roadracer, had a full hip replcement done sometime in the 90's. He's an ex-dirt tracker, and had too many hard tumbles in that discipline. He's still racing and still competetive in the AMA series.
