Abstract:

Objective To obtain the anatomy parameters of the anterior lateral ligament (ALL) of the knee, such as the appearance rate, morphology and anatomic relationship with adjacent structures.   Methods Totally 40 cases of Chinese adult cadaveric lower limb specimens were studied. The anterolateral section of the knee was dissected and ALL was exposured. The anatomic relationship between ALL and neighboring structures was observed and the length, thickness and width were measured when the knee joints were flexed to 90°.   Results The average length of the ALL was (38.04 ± 6.14) mm, the width was (5.39 ± 2.80) mm and the thickness was (0.93 ± 0.52) mm when the knee flexion angle was 90°.   Conclusion The anterior lateral ligament (ALL) is a unique and definite ligament of the knee joint, which has great significance for the stability of the knee joint.
