In reply to indigo: I'm old, obviously, but the recovery was quite quick, really. Bit of day surgery towards the end of December and, come February, I was paying for an annual membership at the wall. By way of contrast, for the SLAP repair that preceded it by a few years my arm was up in a sling for six weeks.
I've never been as strong as I was before these two operations but that may be age rather than a failure to recover from the surgery. Long term, overall? Dunno, operations are rarely the best thing to happen to a person during their life.
