Was it repaired?
If you already have had it surgically repaired, then you have been assigned an orthopedist, whose advice, obviously you should follow.
If it was not a full tear, and was not treated surgically, and it is a guessing game as to how much you can do with it. Rehab, per se, won't help your chances of further tear. It is inherent to the injury itself and your own situation, your ultimate success.
