Glenn ... My wife had rotator cuff surgery about a year ago ... like any such procedure, the hardest part is the post-op therapy ... if you don't go through the pain, you won't enjoy the gain ... She was diligent with it and has full use ...
Make sure you have a Doc you have faith in (check on his past performances if you can), and ask how many of these procedures he performs in a month ...
Best of luck,
