Partial Articular Supraspinatus Tendon Avulsion (PASTA) Repair: Transtendinous Technique.

Abstract

Background: Partial articular supraspinatus tendon avulsion (PASTA) lesions are a common cause of shoulder pain and dysfunction. Transtendinous repair is a surgical technique used to restore tendon integrity while preserving intact tendon and minimizing iatrogenic tendon damage.

Indications: This technique is indicated in patients with symptomatic, partial-thickness rotator cuff tears who have failed conservative management.

Technique description: The PASTA transtendinous technique repair is performed in the beach-chair position. The articular-sided tear is visualized, debrided, and 2 suture anchors are placed percutaneously through the tendon into the rotator cuff footprint. The sutures are passed in a boxed mattress configuration, and knot-tying is performed arthroscopically on the bursal side of the cuff, securing the tendon back to its footprint and preserving intact tendon fibers.

Results: This construct demonstrates stable fixation of the tendon to its native footprint, with preservation of tendon integrity. Postoperatively, patients undergo a structured rehabilitation protocol. Return to full activity/sport is expected at approximately 4 to 6 months.

Discussion/conclusion: Transtendinous repair of PASTA lesions provides a reliable method for restoring native tendon integrity, while preserving intact tendon fibers. This technique minimizes tendon trauma compared with traditional "take-down" rotator cuff repair techniques, maintains native anatomy, and facilitates anatomic healing with good functional recovery.
