Disorders of the long head biceps tendon are among the most challenging of shoulder problems to diagnose and manage. In this Technical Note, we introduce an arthroscopic technique for proximal biceps tenodesis high in the groove at the articular margin of the humeral head using a single anchor and 2 self-cinching loops followed by 5 alternating half-hitches to secure the construct. This method is simple and enables stable fixation of the biceps tendon.
