Background: Although the main pathology of recurrent anterior shoulder dislocation in younger patients is proved to be the injury of the anterior capsular mechanism such as Bankart lesion, the pathology in older patients has not been thoroughly discussed. The purpose of this study was to clarify the pathological condition of the recurrent anterior shoulder dislocation in the middle aged or older patients, and to investigate the results of arthroscopic surgery. Methods: Twenty-eight patients of recurrent anterior shoulder dislocation had arthroscopic surgery performed at the age of forty or older, between 2003 and 2009. There were 13 men and 15 women, and the mean age at the surgery was 53.6 years old. The pathological condition which causes anterior instability was investigated according to the imaging findings and arthroscopic findings. The results of arthroscopic treatment were checked in twenty-two patients who were followed for at least one year after surgery. Results: A variety of anterior capsular mechanism injuries were present in all patients, whereas rotator cuff tear was likely present in older patients. Among the injuries of anterior mechanism, AIGHL tear or HAGL lesion were frequently seen. Arthroscopic stabilization procedure resulted in a favorable outcome. Conclusion: Anterior capsular mechanism injury was the main pathology of the recurrent anterior shoulder dislocation in older patients as well as in younger patients. Arthroscopic repair of the anterior mechanism seemed to be the most important treatment even in the case of concomitant rotator cuff tear.
