To investigate the arthroscopic treatment of recurrent shoulder dislocation and to evaluate the treatment effect. We treated 15 cases of recurrent anterior shoulder dislocation with arthroscopy, aged 25-33 years, all with 4-10 recurrent dislocations, combined with physical signs such as muscle atrophy, decreased joint mobility, fear test, anterior and posterior drawer and compression test, assessed the degree of damage to the glenoid labrum and joint capsule complex using imaging data including X-ray, 3D CT, MRI, etc. Arthroscopy was performed under general anesthesia, and microscopic Repair of glenoid labral complex or bony Bankart injury, management of Hill-Sachs injury, and tightening of the anterior and posterior capsules were performed. After surgery, functional exercises were performed under the protection of an abductor brace, and normal activities were gradually resumed in 8-12 weeks. RESULTS: Satisfactory results were obtained in all cases, with satisfactory recovery of joint function. Some cases with mild limitation of shoulder external rotation resumed normal life and work after 6 months. It can be seen that arthroscopic treatment of shoulder dislocation has unique advantages and real efficacy. Through microscopic evaluation of the intra-articular injury, the anterior and inferior stabilizing structures of the injury can be reconstructed according to the pathological mechanism of joint dislocation, and the compression fracture of the posterior humeral head can be dealt with. Arthroscopic surgery is safe, minimally invasive, with few complications, low recurrence rate and good functional recovery. The key to successful surgery is patient selection and access establishment. With the popularity of arthroscopic technology, shoulder arthroscopic operation is no longer a problem limiting treatment. It is recommended that patients with first-time and recurrent shoulder dislocations be further examined with 3D CT or MR and considered for arthroscopic surgery if necessary.
