Once you get surgery, write on a calender 7 months from that day with your end goal in mind. Mine was to do a standing back flip on the ground. I figured that was the hardest physicaly dynamic thing I could do before I was hurt. So In my mind that would mean a %100 recovery. When your recovering at the begining you will see a lot of progress quick. But as the healing process goes on into the 4-5 month marks it really slows down (that is normal). Having the date written on a calender really helps the fustration by reminding you that your not scheduled to be good to go yet. Everyone is all about the muscle strenthing and it is very important, but in my opinion the most important thing is to not re injure your self. I didn't go super hard in the gym untill the last 2 months. Just do everyday life as best as you can without pain. If it hurts STOP! and go back a notch. The best advice you will get is from your own body. When you knee hurts its pissed. So go easy on it.
The best advice I can give you is, this is a serious injury and it will heal with time if you take care of it properly. Don't make the next ski season your main focus. Make the rest of your life your main focus.
I got a Hamstring graft in May 2010, In November I achieved my goal of the Standing backflip and worked as a Ski Instructor that Ski season. I wore a Knee brace for that first ski season, with some discomfort some days. But now I no longer require a Knee brace and I competed in the Freeride World Tour this past year with no pain.
Good Luck life goes on and remember your going to be alive for a long time. The ^ months will be brutal but once its over you will forget all about it.
