Arthroscopy in a right shoulder with the patient in the beach-chair position. The interval region is visualized with the scope in the posterior portal, showing a torn lateral pulley due to the complete supraspinatus (SSP) lesion expanding into the interval tissue (A) and an uncovered SSP footprint (FP) area (B). (C) With the scope in the anterolateral portal, the posterior extension of the retracted full-thickness tear in the posterior SSP portion and infraspinatus (ISP) can be seen. (D-F) Arthroscopic views from lateral portal. (D) After mobilization, the tendon can be reduced with a grasper in the footprint area. In this case, a biceps (long head of the biceps tendon [LBT]) tenodesis was performed. The footprint is decorticated and medialized 0.5 mm with a bone-cutting device, the medial-row anchors (BioComposite Corkscrew FT Suture Anchors, 5.5 mm × 14.7 mm, with 4 No. 2 FiberWire sutures) are placed at the bone-cartilage junction (E), and sutures are shuttled through the tendon by a mattress technique. (F) The sutures (asterisk) are tied and, under slight tension, inserted in the lateral row of anchors (LA) (BioComposite SwiveLock SP, 4.75 mm × 24.5 mm).
