zjrog, I don't have much pain at all. I realize I'm sort of splitting hairs because I need the surgery, I have it scheduled, and I might as well get it over with. But I've built up to riding 7-10% grades, and still don't have any pain. So the part of me that would like to put off the disruption, pain, and physical therapy is focused on the fact that my knee isn't giving me much trouble at all.
