Never had surgery yet, but still 23 years later do my rehab shoulder exercises three four times a week. I have to be careful with the right shoulder lifting above my head. This injury is always the worse thing I've ever experienced. At least when it happens I know what to expect.
Think i woud be out of business if i couldnt work with my arms over my head. But its likely less likely as the muscles are developed from doing that kind of work for 20 plus years.
