Summary
A surgical technique description for use of the Tetrous EnFix device in arthroscopic rotator cuff repair procedures.
Abstract
The high retear rates in rotator cuff repairs, ranging from 13% to 38%, pose a significant challenge in orthopaedic surgery, primarily due to issues with tendon ingrowth. Despite advancements in surgical techniques, the lack of biological optimization remains a significant hurdle. The Tetrous™ EnFix™ device, utilizing demineralized bone fibers (DBF), offers an innovative solution by promoting osteoinductive and osteoconductive processes. This aids in the formation of the enthesis, thereby enhancing tendon-to-bone healing and potentially reducing retear rates. Preclinical and experimental studies suggest that DBF significantly improves tendon-bone healing, though clinical validation is still needed. In this technical note we portray the use of shaped demineralized bone fiber implant as an augmentation in arthroscopic rotator cuff repair and arthroscopic suprapectoral biceps tenodesis. This technique shows promise in addressing the biological aspects of tendon healing, potentially offering a safe and effective approach to reducing retear rates.
