Additional Half Hitch is Necessary for Knot Tying in Arthroscopic Shoulder Surgery: A mechanical testing Study

INTRODUCTION: Orthopaedic surgeons have focused on improving the functional and structural outcomes of arthroscopic rotator cuff repair and labral repair through the development of biomechanically superior surgical techniques such as double-row fixation, suture-bridge fixation, and compression double-row fixation. To obtain the maximum benefit from these repair techniques, secure knot tying is necessary. The purpose of this study was to investigate the mechanical characteristics of arthroscopic knots, focusing on the effect of tying additional reversed half hitches on alternating posts (RHAPs) during knot tying.
