Mine wasn't so bad, at least not as bad as everyone kept telling me.
My Dr was a Polack, super nice guy and into bird photography. He told me that he was doing an experimental surgery on my shoulder and the recovery would be unorthodoxed. He made the cuts and used a mesh to tie everything together and then told me he wanted me out of the sling and using my arm in 36hrs. He also said it would be extremely painful for a year. That was December 30th of 2011. I was hunting ducks January 1st 2012. I bought a Browning Gold 20ga, my usual shotgun was a Auto-5 Mag-12. I told my buddy Scott that this was the most pain I had ever endured. I was back at work 2 weeks later and using my arm what little I could.
A year later we were hunting the same slough on my property and I told Scott that my arm didn't hurt anymore, that was January 5th of 2013. I don't remember when it stopped hurting, I just remember he made a joke about me using the 20ga one armed and killing a limit of wood ducks the previous season out of the same blind and he had hunted with people who couldn't kill 3 ducks with both arms.
I took my Dr out there after both seasons and I bet he burnt up 20 rolls of film taking pictures of wood ducks, mallards and green wing teal. My dad has the only picture I had framed of a banded wood duck drake over his desk. I told Scott it was hard not to go back down there with a pellet rifle.
I told that to tell you, I don't know what was so different about how he repaired my rotator cuff, but I do know that I didn't lose mobility of my arm after it completely healed. I was in excruciating pain for probably 6 months and it slowly subsided. I know that several people I worked with couldn't believe it when I returned to work 2 weeks after the surgery. Within a few years of my surgery, I had 2 coworkers go to him and have the same surgery, both were back within 2 weeks and both said the recovery wasn't as bad as people made it out to be. He even fixed my FIL's (at the time) collar bone and he never complained about the pain or recovery.
