描述了四肢正常发育的蜥蜴的膝关节和跗关节（踝关节）的结构和功能。结果表明，膝关节严格为铰链型，但不对称，导致小腿长轴相对股骨长轴向内侧弯曲。跗骨系关节是一个复杂的螺钉关节，允许小腿在足部上进行联合旋转运动以及屈伸运动。这些运动是通过关节两侧的互锁控制表面来调节的，并且是这些表面的几何形状的外部表达。这些关节的形态及其允许的运动是根据肢体节段在收缩过程中的运动来评估的。
The structure and function of the knee and mesotarsal (ankle) joints in lizards with normally developed limbs is described. It is shown that the knee joint is strictly of the hinge type, but is asymmetrical, resulting in a mesial inflexion of the long axis of the crus relative to that of the femur. The mesotarsal joint is a complex screw joint which permits conjunct rotatory movements of the crus on the pes, as well as flexion-extension. These movements are mediated by interlocking control surfaces on either side of the joint, and are an external expression of the geometry of these surfaces. The morphology of these joints, and the movements they permit are evaluated with reference to the movements of the limb segments during retraction.
