The presence of an intra-articular air bubble adjacent to the rotator cuff at the time of diagnostic shoulder arthroscopy will confirm an intact rotator cuff and is helpful in ambiguous cases. After the introduction of the arthroscope, air is pulled owing to negative air pressure in the joint cavity. Fluid inflow is then started after the inflow has been properly flushed of all air. This creates an intra-articular air bubble, which can be found at the top of the capsular-supraspinatus attachment site in cases with an intact rotator cuff. Secondary subacromial positioning of the arthroscope is used to confirm the intact rotator cuff from the bursal side.
在诊断性肩关节镜检查时，肩袖附近存在关节内气泡可证实肩袖完整，这对疑难病例很有帮助。插入关节镜后，由于关节腔内的负压，空气被吸入。在冲洗掉所有空气后开始注入液体。这会产生一个关节内气泡，在肩袖完整的情况下，该气泡可在关节囊 - 冈上肌附着部位的顶部找到。关节镜的二次肩峰下定位用于从滑囊侧确认肩袖完整。
