Thanks for the input. My ortho is a sports medicine specialist at SOAR in Redwood City and I like him pretty well so far. He appears to appreciate my desire to get active asap. Unfortunately, my activity level is still capped by soreness in the knee. The cortisone shot has kicked in and is definitely helping in this regard, but I still am maxing out at about 50 mins of no-impact indoor activity (spinning cycle and elliptical). I'm swimming to try and maintain my cardio fitness, but I know my endurance is completely shot.
