I had my ACL reconstructed back in 2012. The best bit of advice I can give is find a good Physical therapist, let them know what you want to be able to do, and then do exactly what they tell you.. Religiously! Nick gave a pretty strait forward break down. Every PT does it a bit differently, but that was pretty close to how mine went. They had me build the muscles in my leg and once it was stable and reaching full range of motion work a lot of fast twitch movements since I was planning to grapple again. It took me awhile to get my confidence back in the knee as well. Again though the best advice I can personally give is rehab the hell out of it. Its painful and can take awhile so just be patient and listen to your physical therapist.
