We performed arthroscopic surgery on 10 labral tears of the shoulder resulting from baseball overhand activities. The average age of patients was 19 years and the average history of baseball activities was 8 years and 8 months. Mean follow-up period was 15 months. All patients have returned to baseball activities after the arthroscopic surgery. 9 of 10 patients had no pain in throwing a ball and 1 patient had only a small amount of pain when throwing a ball. Arthroscopic surgery is an effective treatment for patients who have shoulder pain from sports injuries. The indications for arthroscopic surgery and post operative rehabilitation are important for patients to be able to return to sports.
