Video Summary

Dr. Craig Morgan explains that biceps tendon issues often stem from lesions in the anterior rotator interval, not the biceps itself. The key pathology is failure of the superior glenohumeral ligament (SGHL), causing biceps instability and pain. This manifests as isolated upper biceps pain, increased external rotation, and a widened biceps outlet visible arthroscopically and on MRI. The recommended treatment is rotator interval closure, stabilizing the biceps by repairing the SGHL and upper middle glenohumeral ligament. Biceps tenodesis is discouraged as it disrupts shoulder mechanics and risks arthritis. The interval lesion repair yields high success with minimal complications.
