Pressure and area of contact curves of the ankle joint were determined in various degrees of flexion and with the external ligaments in different states of severance or division, using five ankle joint preparations as basis. The largest contact area and most uniform pressure distribution were seen if the ankle was in normal position and at a plantar flexion of five degrees. After injury of the external ligaments there was either a reduction of the area of contact associated with a pressure increase, or an increase of the area of contact associated with an inhomogeneous pressure distribution. The greatest loss in area of contact and pressure increase occurred after lesion of the fibular ligaments in supination and supination/plantar flexion of the foot. The moment of rotation for supinatory forces applied to the margin of the foot, increased continuously in that case.
以五个踝关节标本为基础，测定了踝关节在不同屈曲程度以及外侧韧带处于不同切断或离断状态下的压力和接触面积曲线。如果踝关节处于正常位置且跖屈5度时，可见最大接触面积和最均匀的压力分布。外侧韧带损伤后，要么接触面积减小且压力增加，要么接触面积增加且压力分布不均匀。在足内翻和内翻/跖屈位腓侧韧带损伤后，接触面积损失最大且压力增加。在这种情况下，施加于足边缘的内翻力的旋转力矩持续增加。
