Despite the recognized importance of the anterolateral ligament (ALL) in rotational stability of the knee, some studies still deny its role and even its existence. We studied the prevalence of the ALL in a Caucasian population, as well as its characteristics and anatomical relationships.
The study was performed on 20 knees from 10 embalmed cadavers. A lateral approach, as described by Steven Claes, was used and the relations of the ALL with the lateral epicondyle, lateral inferior genicular artery, lateral meniscus, Gerdy's tubercle and fibular head were recorded. Its length and its width were also measured.
The ALL was identified in 16 knees. Its origin was at a distance inferior to 1mm posterior and proximal to the lateral femoral epicondyle and insertion within a mean distance of 2.1±0.6mm from de tibial articular surface, 20.6±1.3mm from the Gerdy's tubercle and 20.3±1.2mm from the fibular head. In all cases ALL presented mutual fibers with the lateral meniscus. The length was 35.8±4.6mm and the width was 4.2±1.3/4.9±1.0/6.5±1.5mm at its proximal, middle and distal third, respectively. No difference was found between gender and the dimensions of the ligament.
The ALL was found in 80% of the knees. Its origin is closely related to the lateral collateral ligament and its insertion is halfway between the fibular head and the Gerdy's tubercle. In all cases, we verified the connection between ALL and the lateral meniscus.
尽管前外侧韧带（ALL）在膝关节旋转稳定性中的重要作用已得到认可，但一些研究仍否认其作用甚至其存在。我们研究了白种人群中ALL的发生率及其特征和解剖关系。
对10具防腐尸体的20个膝关节进行研究。采用Steven Claes描述的外侧入路，记录ALL与外侧髁、膝下外侧动脉、外侧半月板、Gerdy结节和腓骨头的关系。还测量了其长度和宽度。
在16个膝关节中发现了ALL。其起点位于股骨外侧髁后方近端1mm以内，插入点距胫骨关节面平均距离为2.1±0.6mm，距Gerdy结节20.6±1.3mm，距腓骨头20.3±1.2mm。在所有病例中，ALL均与外侧半月板有相互纤维连接。其长度为35.8±4.6mm，近端、中部和远端三分之一处的宽度分别为4.2±1.3/4.9±1.0/6.5±1.5mm。性别与韧带尺寸之间未发现差异。
在80%的膝关节中发现了ALL。其起点与外侧副韧带密切相关，插入点位于腓骨头和Gerdy结节之间的中点。在所有病例中，我们都证实了ALL与外侧半月板之间的连接。
