The Superior Fascicle of the Anterior Talofibular Ligament Functions as a Restraint Against Internal Rotation: A Cadaveric Biomechanical Study.
BACKGROUND Lateral ankle sprains frequently result in anterior talofibular ligament (ATFL) dysfunction, leading to chronic lateral ankle instability. The ATFL consists of superior and inferior fascicles; however, the stabilizing role of the superior fascicle remains unclear. We biomechanically evaluated its function us...
