I hurt my shoulder in a water-skiing accident last summer. It's starting to dislocate more often, even with mild activity. Do I need surgery for this problem?

Most likely. Most surgeons will suggest surgery when this problem keeps happening over and over. You can damage the joint if it is left untreated and it continues to dislocate. If dislocation only happens once or twice, it is possible that a series of physical therapy sessions could help ease pain and restore movement. However, a significant dislocation stretches out the ligaments that hold the joint steady. Once these have been injured, it is questionable whether the joint will stay in place without surgery.
