Sorry to hear that buddy. I tore my ACL beginning of 2011 season. Was devasted and had nothing to do whole summer except going to the games and watch my team play.
But here are few suggestions -
1. Get the surgery done as soon as possible. Do it once the swelling is gone and you feel you can do normal activities like walking etc. The reason I am saying is because I delayed mine for 6 months and to compensate for ACL deficiency, my body started to over use other muscles like calf, ankle etc and your body never forgets that even after reconstruction and rehab.
2. Once you go under the knife, its all about rebuilding your injured leg - lots of protien intake. You will lose lots of Quad muscles due to atrophy and they need to grow back.
3. Dedicated rehab, no short cuts exist, trust me. Do as prescribed, push it if you can, like put in an extra set. But does not mean start sports till doctor recommends.
4. Dont do any exercise where your limbs are hanging like leg extensions. Leg presses, squats etc are the best way to start.
5. There is plenty of information available online. The rehab here in US was expensive and insurance doesnt cover it beyond 3 mths. I read a lot on how others recovered, stayed away from any sport, and worked out as hard as I could.
I feel absolutely normal now, no pain at all.... And glad I got the reconstruction done. Knee is a complex structure, any weakness can cause other soft tissues to deteriorate or fail causing more trouble.
With regular rehab, you should be ready for sports in 6 months after surgery and will still have 1-2 months to get used to it before season starts.
Goodluck!
