Shoulder arthroscopy in expert hands is now a tool for diagnosis and treatment. Diagnostic shoulder arthroscopy begins with a systematic review of the shoulder. This review should include the ramp test for confirming normal superior glenohumeral ligament (SGHL) integrity and function. The ramp test uses manipulation of the biceps tendon to achieve this. A negative ramp test finding means that the SGHL is intact and the biceps tendon moves freely down in a V-type pattern. A positive ramp test finding results when the biceps tendon subluxates through a failed SGHL and therefore presents with a U-shaped pattern indicating pathology. Intra-articular biceps tendon instability occurs due to SGHL tearing, which can lead to upper subscapularis rotator cuff partial tears or complete tears either acutely or over time.
