My husband had this surgery. He had torn his rotator cuff years ago that ended up needing some repair and he had bone spurs that were cutting into a tendon.
He was not allowed or released to go back to work for 3 months. The first week was pretty painful for him. He freaked a little right after because they didn't tell him that he wouldn't be able to move his arm. Once we called we realized that was normal. He didn't do PT, they just gave him exercises to do with one of those bands, and they continued to check his progress.

Good thing is, this was 4 years ago and his shoulder is doing great. He has no pain or recurring problems. He is very happy he had it done. He is a police officer, so he really needs full use of both arms.
