Good for you and hubby in standing up for your rights as a patient. Knowing how important it was to you for an early morning appointment in advance, it was disrespectful to be jerked around for their convenience.

According to my physical therapist (who gets to sit in on occasional ortho surgeries) the reps are there to provide info on new versions of the implant hardware. He said the surgeons do sometimes ask for input on choosing hardware on a particular operation, and the reps are well versed in the technical specs and uses of what they sell with updated versions in production. It does seem odd to me too, to allow extra people in the operating room.

I don't understand your doctor refusing your request for physical therapy, it seems like a logical simpler step to try the less harmful solution both before committing to surgery, as well as really so important afterwards. I am glad you are switching surgeons for your next one.
