Hagiwara Y, Kanazawa K, Ando A, et al. - This study was attempted to assess the association among range of motion (ROM) under general anesthesia before surgery and the effects of each joint capsular release on ROM. A goniometer with scapular fixation was applied to measure ROM. Researchers conducted arthroscopic pan-capsular release with the patient in the beach-chair position in the following order: rotator interval, coracohumeral ligament, superior capsule, middle glenohumeral ligament, anterior inferior glenohumeral ligament, and posterior inferior glenohumeral ligament. This study included a sum of 32 consecutive shoulders. They further analyzed ROMs in forward flexion (FF), lateral elevation (LE), external rotation with the arm at the side, external rotation at 90° of LE, internal rotation at 90° of LE), horizontal flexion, external rotation at 90° of FF, and internal rotation at 90° of FF before and after each release. The data showed that each segment of the joint capsule affected ROM in all directions, supporting the necessary for whole-joint capsular release; after surgery, ROM was significantly greater on the affected side than on the unaffected side.
