Knotless Arthroscopic Repair of Subscapularis Avulsion Fracture Using a Single Anterior Portal

Abstract

Proximal humerus lesser tuberosity avulsions are uncommon injuries; however, when present, they can be debilitating for patients. As such, they pose a unique clinical challenge. These fractures were traditionally treated through an open approach to the proximal humerus; however, arthroscopic techniques continue to evolve and are increasingly used for these types of injuries. We describe our minimally invasive arthroscopic technique to repair lesser tuberosity avulsions using standard arthroscopic equipment. This method is safe, efficient, and applies basic shoulder arthroscopic techniques.

Single-Portal, Single-Anchor Repair of a Superior Third Subscapularis Tear Using a Self-Punching Knotless Soft Suture Anchor

“… 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 Through the advancements of arthroscopic techniques, numerous investigators have proposed various techniques of varying complexity for repair of isolated subscapularis tears. 18 , 26 , 27 , 28 , 29 , 30 , 31 , 32 Van der Zwaal et al. proposed that an additional anchor should be placed for every 1 cm of the subscapularis involved in the tear.…”

“… 15 , 25 Since the advent and advancement of arthroscopic techniques, many techniques have recently evolved for arthroscopic subscapularis repair. 18 , 26 , 27 , 28 , 29 , 30 , 31 , 32 To our knowledge, in regard to arthroscopic repair of Lafosse type II/superior third subscapularis tears, there exists no published literature highlighting the efficacy of using a single, knotless soft suture anchor solely through an anterior working portal. The purpose of this Technical Note and video ( Video 1 ) is to present an arthroscopic repair of a full-thickness superior third subscapularis tear using a knotless, soft anchor through a single anterior portal.…”
