Abstract
Arthroscopic repair of subscapularis tendon tears has shown to be a reliable and reproducible technique and is now considered the gold standard method over open repair. However, most arthroscopic techniques use several working portals and the procedure can be technically challenging and time-consuming, especially when knot-tying is required and when multiple anchors are used. Recently, single-portal knotless techniques have been popularized for upper-third lesions (e.g. Lafosse type 1 or 2 tears). Here, we describe a technique of repairing complete tears of the subscapularis tendon (Lafosse type 3 and 4) using knotless suture anchors through a single portal. This technique is quick and allows a safe anatomic footprint repair to the lesser tuberosity.
