Is physical therapy for a right hip arthroscopy re labral tear normally "1 day post op and then 1 time per week for first 6 weeks"? seems quick.

Not necessarily: As long as there is nothing 2 heal, the sooner the better.

Depends on procedure: If this involved simple trimming of labrum may be adequate. More complex procedures requiring periods of crutch use and limited weight bearing may require more face time with the physical therapist. Also in my experience young motivated patients may not require as much time with the therapist, as they are more than able to perform exercises/home therapy as long as given proper direction.
