Abstract
Latissimus dorsi (LD) transfer is a reliable treatment option for irreparable posterosuperior (PS) rotator cuff tears in young and active patients that need to recover the range of motion for their daily living activities. The technique starts with an arthroscopic assessment of the tear. The next step is the mini-open stage for muscle release from the subcutaneous layer of the skin, the teres major (TM), the triceps, and the lateral border and inferior angle of the scapula. Later, the scope is used to prepare the footprint (arthroscopy) and for the release and the harvest of the tendon (endoscopy), taking care not to detach the TM and not to damage the radial nerve. A grasper is used to push the LD to its correct path medial to the triceps. After that the same instrument is placed from the anterolateral and the anterior arthroscopic portals toward the mini-open incision to catch the sutures previously loaded on the LD tendon with Krackow stitches. The LD is transferred to the greater tuberosity and is attached with one medial and one lateral knotless anchors. A third point of fixation enables a partial RC repair and ensures a surface of bone to tendon healing.
