that sucks man, I know how you feel. I've torn my ACL before, it wasn't fun. Also dislocated my kneecap in the same leg. I've had my fair share of injuries, worst being when I shattered my right elbow into about 15 pieces. That was the worst ever. Still have 5 screws and some wires in there holding it together. That was 3 years ago and it still won't straighten out!
Good luck to you!
