I tore my lcl, patella, and mcl 11 months ago and I am still not 100% because I started rolling to early (about 3 months after the injury). I am about 80% now and I roll 3 days and workout 5 days a week now. Bottom line, listen to your body and your doctor/PT!!! Don't start back to early or it will just tack that much more time onto your overall recovery. Don't be stubborn and try to get back in there to early. If you want to go to class to practice techinique in a month or 2 that should be fine, but I wouldn't roll live for at least 4 to 6 months depending on how your body feels. Also, don't get discouraged when you go back to class and you're not at the same level as when you got hurt. Your timing is going to be off and your sweeps, subs, and passes won't be as "sneaky". I struggled to get my timing, transitions from sub to sub and sweep to sweep, and my setups back when I started training again. Good luck to you and I wish you the best.
