Shoulder arthroscopic surgery is one of the fastest growing disciplines in the field of surgery and sports medicine in the last twenty-five years. Shoulder arthroscopy, like other arthroscopic surgeries, requires specialized shoulder arthroscopic instruments and equipment. It requires the shoulder arthroscopist to select two to three 5 mm length surgical entrances in the shoulder joint area, implant the shoulder arthroscope and surgical instruments, use sutures and suture rivets for suture fixation of the ruptured muscle and tendon tissues, power grinding system instruments for bone tissue and related soft tissue removal, and postoperative combination with advanced The postoperative period is combined with advanced sports rehabilitation training to achieve a good therapeutic effect of minimally invasive surgery. Because of the advantages of accurate diagnosis, small surgical trauma, precise surgery, no need for secondary surgery to remove the fixed consumables, and significant effect, the shoulder arthroscopy technique is popular among patients with shoulder arthrosis. Minimally invasive shoulder arthroscopy will become the main surgical tool for the treatment of frozen shoulder now and in the future. Which patients need to be suitable for minimally invasive shoulder arthroscopy? Patients with persistent frozen shoulder are those who have been ineffective after more than 3 months of conservative treatment, with prolonged persistent pain, skeletal deformities, severe lesions or ruptures of rotator cuff tendons, intra-articular adhesions and contractures of the joint capsule resulting in severe dysfunction of the shoulder joint, or those who have subacromial bones causing significant impingement, and these patients should be actively treated surgically.
