Steve,

It's not the end of the world and your sailing days are not over! Sure, the rehab is tough, but my wife is biking and hiking again. Right now her pace at both is pretty tame, but the weekly improvement is pretty incredible. Here's the back story... When my wife was 8 or 9 she was hit by a car. She went through reconstructive surgery for her left knee and pretty much every bone in her left leg and a couple in her right. At ~44 her left knee was pretty much worn out. At 45 she decided it was time to have her knee replaced.

Let me know if you want her e-mail address. She would be more than happy to converse about it and put you in touch with her doctor and a friend who had the same procedure done by the same doctor.
