The kinematics of rotational motion of the knee joint is described by a three-dimensional mathematical model. It is on principle supposed, that cruciate ligaments interact in concert to guide motion. This concept is based on the idea to explain movement in the sagittal and horizontal plane by a four-bar kinematic chain. The path of the instantaneous centers of rotation is shown with the help of this concept.
膝关节旋转运动的运动学由一个三维数学模型描述。原则上假定，交叉韧带协同作用以引导运动。这一概念基于用四连杆运动链来解释矢状面和水平面运动的想法。借助这一概念展示了瞬时旋转中心的轨迹。
