You may know this already but... sometimes the docs don't explain completely... the shoulder is a shallow joint that is held together by strong, nonstretchy, fibrous tissue. When you dislocate it you HAVE to put a tear in that tissue. It heals by making a scar, which is always somewhat weaker than the noninjured tissue. The younger you are when you first dislocate, the more the likelyhood that you will do it again. Physical therapy strengthens the muscle surrounding the joint and helps support the weakened area. Be religious about it. It will certainly decrease your risk of another dislocation and possible surgery.
