Surgical technique for xenograft (SIS) augmentation of rotator-cuff repairs

Chronic rotator-cuff tears, especially when there is insufficient tendon to perform a repair, remain a surgical challenge. Multiple salvage techniques have been described; however, the results are significantly worse then primary repairs. Reconstruction with a pleuripotential xenograft (porcine small-intestine submucosa) has been shown to simulate normal tissue in-growth in animal studies. In this article, we report our surgical technique and 2-year follow up of 12 patients.

Augmentation of chronic rotator-cuff repairs with a small-intestine submucosa graft appears to be safe and results in significant increases in strength, motion, and functional assessments. Long-term studies and studies are needed to determine the role of small-intestine submucosa grafts in rotator-cuff surgery.
