目的：对踝关节外侧韧带有深入的了解是了解其功能、病理生理和治疗选择的必要条件。踝关节外侧副韧带由距腓前韧带（ATFL）、跟腓韧带（CFL）和距腓后韧带（PTFL）组成。虽然以前的研究已经报道了这些韧带之间的连接在其外侧，没有研究专门评估的连接在内侧。本研究的目的是评估踝关节外侧副韧带复合体组件之间内侧连接的形态和一致性。方法在40侧新鲜冰冻踝关节标本上，解剖观察踝关节外侧韧带的连接情况。外侧韧带可视化后，腓骨被切断，韧带止点在距骨和跟骨止点被释放。观察韧带的连接情况，并对韧带连接的动态关系进行录像分析。结果所有病例ATFL与PTFL、ATFL与CFL、CFL与PTFL均存在连接。ATFL和PTFL之间的连接并不均匀。虽然在所有病例中（40例）观察到ATFLif和PTFL之间的连接，但只有17个踝关节（42.5%）ATFLsf和PTFL之间存在连接。连接纤维的数量也是可变的。结论从踝关节内侧可以观察到踝关节外侧副韧带3个组成部分之间的联系，这对关节镜下外侧副韧带修复具有重要意义。
Purpose A deep knowledge of lateral ankle ligaments is necessary to understand its function, pathophysiology and treatment options. The ankle lateral collateral ligament is formed by the anterior talofibular ligament (ATFL), the calcaneofibular (CFL) and the posterior talofibular ligament (PTFL). Although previous studies have reported connections between these ligaments on its lateral side, no studies have specifically assessed connections on the medial side. The aim of this study was to assess the morphology and consistency of the medial connections between the components of the lateral collateral ligament complex of the ankle. Methods Forty fresh-frozen ankle specimens were dissected to look for connections between the three lateral ankle ligaments. After visualization of the lateral ligaments was achieved, the fibula was amputated and ligament insertions were released at the talar and calcaneal insertion points. Observation of the connections and video analysis of the dynamic relationships of ligament connections were performed. Results Connections were found in all cases between the ATFL and PTFL, the ATFL and CFL, and the CFL and PTFL. Connections between ATFL and PTFL were not homogeneous. Although connections between the ATFLif and PTFL were noted in all cases (40), only 17 ankles (42.5%) had connections between the ATFLsf and PTFL. The amount of fibres of connection was also variable. Conclusion Connections between the three components of the lateral collateral ligament of the ankle may be observed from the medial aspect of the ankle, and this may have important implications for arthroscopic lateral ligament repair.
