i tore my ACL a couple of months ago and am having knee surgery next thursday. i started rehab before the surgery and plan to workout and rehab the knee at every opportunity. i chose the hamstring graf option. i'm trying to be optimistic in thinking that i'll be back on a bike by this september... anyone out there who has recently had ACL surgery have any advice or words of wisdom to pass on it would be apprec. i am well aware of all the obvious, and have found plenty of ACL-related support groups on the Web. sorry in advance if this is too far off topic. however, i also want to hear what motocrossers have to say. 1. how long before you were back on the bike practicing? 2. how long before racing? 3. was there anything in paticlar that you did to speed recovery? 4. how realisitic am i being by thinking i can climb back on by this Fall? thanks.
