MRI's are great but don't give the complete picture. Many times, after the doctor goes in for the scope they find many other issues that need repair.
If it is just a basic labral repair, it will be a timeline similar to kpsnap, although I personally feel getting some basic, non-manipulative, low level therapy in the initial 4 week post-op period would be very helpful (modalities, etc). But good luck with insurance companies approving them.
I would also highly recommend speaking with your surgeon regarding this. If they are a good orthopedic practice, they should have plenty of post-op procedures and timelines to follow as a guide. Also, when you speak with you physician (either before the surgery or during your post-op follow up), let him/her know your specific goals and what level you want to perform at again.
