My GOD, tell me about it. It was September 09, I was getting hyped and ready for the winter rolling around, then I go and tear my ACL+MCL in soccer. Had my surgery in December so I sat out the whole of the 09/10 season... probably one of the toughest things I've ever had to do, it was super frustrating. My knee still feels like 80% but I'm still doing 2 hours/day PT + gym religiously so hopefully come Novemeber/December I'll be good to go. I shredded two days in July with a simple knee support and it felt good, but not great.
