The authors have studied, on the basis of purely radiologic data, the modifications of the popliteal arterial axis during flexion of the knee. They note the appearance in the sagittal plane of very marked flexures of the upper part of the artery, while the lower part describes a harmonious curve. These modifications take place between two fixed points: a cranial fixed point, represented by the origin of the descending artery of the knee, and a caudal fixed point represented by the origin of the anterior tibial artery. The pathologic importance of these modifications of the course of the artery should not be underestimated when obtaining revascularization by means of an arterial prosthesis.
作者基于纯放射学数据，研究了膝关节屈曲过程中腘动脉轴的变化。他们注意到，在矢状面上，动脉上部出现非常明显的弯曲，而下部则呈现出一条平滑的曲线。这些变化发生在两个固定点之间：一个是颅侧固定点，由膝降动脉的起点代表；另一个是尾侧固定点，由胫前动脉的起点代表。在通过动脉假体进行血管重建时，不应低估动脉走行这些变化的病理学意义。
