Arthroscopic double row partial articular supraspinatus tendon avulsion bridge repair technique for shoulder: A transtendinous approach.

Abstract

Partial articular supraspinatus tendon avulsion (PASTA) lesions, a subset of partial rotator cuff tears, pose a surgical challenge, disrupting the integrity of the supraspinatus tendon. Transtendinous repair is the preferred choice in young individuals for limiting tear progression and preserving intact, high-quality cuff tissue, thus preventing tendon shortening, as compared to the tear completion and repair technique. Our approach leverages these advantages, specifically those indicated for Ellman's Grade 3 tears and cases where conservative treatments have failed. In our technique, we employ progressive dilation, anchor drill sleeve insertion to facilitate medial row anchor placement, followed by percutaneous spinal needles for suture shuttling, and finally locking sliding knots for compressive medial row repair, followed by lateral row fixation for additional stability. This method accelerates rehabilitation and restores optimal shoulder function.
