Age matters, but in a different way. Under age 30, the should tendons are not as stretched out and almost always results in the need for surgery. Over 30 and it gets to 50/50, and over 40 a bit better for subluxations. This is what my sports medicine doctor told me when I subluxed mine. If it was out for only 10 seconds that is good, it took me about 3 months to be back on the bike with PT and ~6 months back to rock climbing.
