Poster 164: Novel Distal Biceps Tendon Onlay Repair with Twin Interlinked Knotless All-Suture Anchors and Reinforced Looping Suture Demonstrates Favorable Failure Load, Footprint Restoration Accuracy, and Tendon-Suture Security: A Biomechanical Study

Compared to whipstitch repairs, reinforced looping suture repairs demonstrated 50% lower mean bone-tendon gap formation (0.8±0.1 mm vs 1.6±0.7 mm), 78% lower mean suture construct elongation (0.9±0.4 mm vs 4.0±1.8 mm), and 46% lower mean total construct elongation (3.0±0.5 mm vs 5.6±2.3 mm) after cyclic loading; the differences did not reach statistical significance.
