Simultaneous Dual-Camera Technique for Partial-Thickness, Articular-Sided, In Situ Transtendinous Rotator Cuff Repair.

Abstract

Articular-sided, partial-thickness rotator cuff tears often lead to shoulder pain and dysfunction. Surgical options include debridement, apposition of resorbable bioinductive collagen implants, tear completion followed by repair, and arthroscopic in situ transtendinous repair. Traditional in situ transtendinous repair, using a single camera, limits visualization of the intra-articular and subacromial spaces, risking tension mismatch and tendon buckling. In this article, we present our technique, which uses two cameras simultaneously, one in the intra-articular space and one in the subacromial space, to enhance visibility and prevent suboptimal suture placement, thereby improving repair quality and footprint coverage.
