This guy sounds more like a Personal Trainer for exercise, than a Physical Therapist.  I think I'd be checking on his licensing, and qualifications.  
My daughter said she didn't remember if it was 3 or 4 months that she had to do the PT.   As soon as she got done with the required PT, she got the surgery.  
speckledhen, even when dealing with private insurance, the rules are almost the same, and it's not much better at all.  The surgeon may be able to help, but normally their hands are tied until the required PT is done.  He may be able to detect added inflammation, etc., and help with some pain reliever.  The post surgical PT is no picnic either, but usually it does get better, so that by the time it's nearly finished, there's little to no pain.
