Alan,
Those asterix are nice, love to try on a pair but you don't see many in Canada. I have a cool carbon fiber custom G-II brace for that side (R knee). Binds a bit when kicking but other than that it seems good for riding. It's some weird lateral tear in the lateral meniscus cartiledge that the MRI doesn't show well. It's not really a hardship and doesn't hurt much when riding as long as I keep my legs strong. More of an "awareness and confidence" thing that lurks iin the back of your mind when riding. Like most of us I have lots of permanent "hurts" from too much racing. Thats life - get on with it and get riding as my wife says. Cam.
