Figure 5.
Inversion-eversion moment rotation curve of the intact ankle and after sectioning the anterior talofibular (ATFL) and calcaneofibular (CFL) ligaments from 1 specimen. Total laxity is the rotation (range of motion in degrees) between +4000 (inversion) and −4000 (eversion) N-mm torque loads. Note: Observe the large increase in inversion rotation after sectioning the ATFL + CFL versus the intact ankle.
