Arthroscopic Bankart suture repair (Morgan's technique) was performed on 20 patients with recurrent anterior dislocation or subluxation of the shoulder. The re-dislocation rate was 5% (1/20), and re-subluxation occurred in two patients postoperatively. Patients who suffered a re-dislocation were operated on again according to the Bristow procedure. The symptoms of the two patients with re-subluxation were not pronounced, and they received conservative treatment. In Morgan's technique, the position of the anterior portal is important. It should be at inferior a point as possible in order to facilitate the suturing process. The reattachment point of anteroinferior glenohumeral ligament-labral complex (AIGHLC) is also important. But sometimes AIGHLC is not clear, and the amount of tension of AIGHLC must be determined by pulling with a grasper. The reattachment point must be determined based on the anatomical figure and the tension of the AIGHLC. When the thread is tied on the fascia of the deltoid muscle, it is difficult to determine its strength. The thread is usually tied so as to make a dimple of about 1 cm at the posterior suture point. If these technical problems can be overcome, arthroscopic Bankart suture repair (Morgan's technique) may be a useful procedure for treatment of anterior dislocation.
