Shoulder instability is a common nuisance for athletes and non-athletes alike. Swimmers, tennis players, and volleyball players report shoulder instability frequently, as do those who have previously suffered a dislocated shoulder. Torn, loose ligaments and tendons in the shoulder are to blame for shoulder instability. Caused by previous sports injuries, or simply day-to-day repetitive use of the shoulder, the earmarks of shoulder instability include chronic shoulder pain, or a feeling that the shoulder may give out. Because shoulder instability can be a chronic, painful condition, Dr. Nadel may determine that Arthroscopic Surgery to repair the torn or stretched ligaments will yield the best results for you. Surgery is a same-day outpatient procedure, which can be done in as little as an hour.
