I had the right shoulder done about ten years ago and it was done arthroscopically. Sling for a few weeks and PT for about 8 thereafter. No lasting aftereffect but long bouts of hard physical work (forking and moving a dumpload of mulch by wheelbarrow, for example) result in twinges.
A couple of years after that I broke the left shoulder in a motorcycle accident with no surgery but about the same followup and results. I can lift what I need to, move what I need to, and ride as far as I need to. My legs are the problem there.
