Comparison between arthroscopy and arthrotomy in the treatment of shoulder instability

Anterior post-traumatic shoulder instability represents a common finding in orthopaedic surgery. The surgical treatment of this lesion is often indispensable for the normal social life of the patient and for the sports activity of the young. The Bankart procedure with capsular retensioning by arthrotomic access has for years been the gold standard. In the last 10 years arthroscopic accesses have gained more and more consent for the surgical treatment of such lesions, with results that have considerably improved in time. It is the purpose of this study to compare the results obtained in patients affected with anterior-inferior post-traumatic shoulder instability treated by Bankart surgery, arthrotomic and arthroscopic, with a minimum follow-up of 4 years.
