Yes, the post op protocols sound a bit contradictory indeed. You should ask the OS for more detailed info on the recovery/rehab. Tell him that you don't understand how it will work, and that you need to know this before moving forward with surgery. Also, let him know that you haven't found a PT with this experience. Maybe he can put you in touch with the PTs he has used for his previous surgeries. In short, don't settle and keep asking until you feel comfortable about the procedure knowledge-wise. Good luck!
