I went through an ACL reconstruction too. Mine was pulled from my hammy, but I noticed a nice breakthrough in PT at about 3 months. I was able to walk briskly on a treadmill, even jog for a few seconds. At 5 months I was jogging (with the brace) pain free. At 7 months, I played in a baseball tournament, much to the anger of my wife and Doctor. I wore my brace. I was sore, but it rebounded nicely. I finally fully ditched the brace at the 10 month mark. I do wear a sleeve now when I play any sport, but its just because it makes me feel safer.
Good luck in your rehab.
