背景资料：膝关节后外侧主要结构附着部位的定量描述尚未完成。目的：定性和定量确定这些结构的解剖附着部位及其与相关骨性标志的关系。研究类型：尸体研究。方法：对10个非配对新鲜冷冻尸体膝关节进行解剖和测量。结果：腓侧副韧带的平均股骨附着点位于外上髁的近端（1.4 mm）和后方（3.1 mm）。在远端，它附着在腓骨头前面后面8.2 mm处。腘肌腱在腘沟的最近端和前五分之一处具有恒定的宽基股骨附着。腘肌腱在股骨上的附着点总是在腓侧副韧带的前方。腘肌腱股骨附着点与腓侧副韧带之间的平均距离为18.5 mm。后股的平均附着距离腓骨茎突尖后内侧1.6 mm，前股附着距离腓骨茎突尖前内侧2.8 mm。这些信息将被证明是有用的解剖修复和重建的膝关节后外侧结构的研究。(C)2003年美国骨科学会运动医学。
Background: Quantitative descriptions of the attachment sites of the main posterolateral knee structures have not been performed.Purpose: To qualitatively and quantitatively determine the anatomic attachment sites of these structures and their relationships to pertinent bony landmarks.Study Type: Cadaveric study.Methods: Dissections were performed and measurements taken on 10 nonpaired fresh-frozen cadaveric knees.Results: The fibular collateral ligament had an average femoral attachment slightly proximal (1.4 mm) and posterior (3.1 mm) to the lateral epicondyle. Distally, it attached 8.2 mm posterior to the anterior aspect of the fibular head. The popliteus tendon had a constant broad-based femoral attachment at the most proximal and anterior fifth of the popliteal sulcus. The popliteus tendon attachment on the femur was always anterior to the fibular collateral ligament. The average distance between the femoral attachments of the popliteus tendon and fibular collateral ligament was 18.5 mm. The popliteofibular ligament had two divisions-anterior and posterior-in all cases. The average attachment of the posterior division was 1.6 mm distal to the posteromedial aspect of the tip of the fibular styloid process and the anterior division attached 2.8 mm distal to the anteromedial aspect of the tip of the fibular styloid process.Conclusions: These structures had a consistent attachment pattern. This information will prove useful in the study of anatomic repair and reconstruction of the posterolateral structures of the knee. (C) 2003 American Orthopaedic Society for Sports Medicine.
