Figure 1.

Arthroscopic image of right shoulder (beach-chair position) from posterior viewing portal within glenohumeral joint. The arm is placed in approximately 30° of external rotation, which aligns the anterolateral portal with the biceps groove. The diseased LHB tendon is grasped by a clamp originating from the anterolateral portal. By use of the same clamp, a mark can be made on the biceps tendon as it enters the joint. This mark will later serve as a reference to the amount of biceps needed to be resected to establish anatomic tension of the tenodesis.
