Sebass67,
Very true man, its a very common surgery. I've heard of the ACL being recontructed from the hamstring. There are advantages and disadvantages to both. I've even heard of people that had their ACL replaced with one from a cadaver, seemed a little too freaky to me, but it probably helps recovery time.
Yea, don't push your knee too hard, reinjuring it would not be fun. I also think my doctor was just being a bit over protective by telling me not to squat because I know a guy that squats in the 500s after having a surgery similar to mine. Since you didn't have your patella messed with I'm sure you will be more than OK to squat once your knee heals a bit.
