The posterior cruciate ligament (PCL) serves as a knee stabilizer in the anteroposterior plane, avoiding excessive posterior translation of the tibia. The PCL is commonly injured after motorcycle‐related traffic accidents due to the impact of backward force on the anterior tibia. The PCL originates from the posterior intercondylar area on the tibial plateau, inserts on the lateral surface of the medial condyle, and extends up to the roof of the intercondylar fossa. Ultrasound (US) scanning of the PCL has been elaborated in many protocols.

后交叉韧带的超声成像及其模拟物，后半月板韧带

后交叉韧带 (PCL) 在前后平面中充当膝关节稳定器，避免胫骨过度向后平移。由于向后的力量对胫骨前部的影响，PCL在摩托车相关的交通事故后经常受伤。PCL起自胫骨平台后髁间区，止于内侧髁外侧，向上延伸至髁间窝顶部。PCL 的超声 (US) 扫描已在许多协议中进行了详细说明。
