Traumatic shoulder dislocation is a common sports injury, the most common of which is anterior dislocation of the shoulder joint. After the first dislocation of the shoulder joint, patients younger than 20 years of age have a 90-95% chance of recurrence. Patients who frequently participate in impact sports or overhead sports activities often suffer from recurrent shoulder instability, resulting in articular capsule and labral lesions, and the humeral head and glenoid, which make up the shoulder joint, can cause varying degrees of articular cartilage damage and even lead to osteoarthrosis, which can seriously affect the function of the shoulder joint. Both incisional surgery and arthroscopic surgery can effectively treat the joint capsule and glenoid labrum lesions caused by joint dislocation. The main advantages of arthroscopic surgery for shoulder dislocation are the accurate and effective diagnosis and treatment of the corresponding injured structures, as well as the reduction of medically induced damage to the surrounding normal tissues (especially to the subscapularis muscle), the significant reduction of pain after surgery, and the significant reduction of scar tissue at the surgical site (good aesthetic results). In addition, there are many reports in the literature on the rapid recovery of shoulder function and less restriction of joint movement angle after arthroscopic surgery compared to incisional surgery.
