The anterolateral complex (ALC) of the knee comprises multiple layers, with continued debate on the identity and function of the structures of the ALC. The Segond fracture, long considered pathognomonic of an anterior cruciate ligament injury, has now been shown to have several attachments to soft tissues of the ALC. To the extent that a Segond fracture, or injury to the ALC more broadly, increases knee rotatory instability in vivo is a question of ongoing investigation. By extension, it remains uncertain whether an untreated Segond fracture adversely affects outcomes and therefore warrants consideration for operative intervention. Prospective randomized studies of anatomic anterior cruciate ligament reconstruction with or without concomitant treatment of Segond fractures are needed to more definitively answer these questions.
膝关节前外侧复合体(ALC)由多层组成,关于 ALC 结构的身份和功能仍存在持续争议。Segond 骨折长期以来被认为是前交叉韧带损伤的特征性表现,现在已经发现它有几个与 ALC 软组织的附着点。在多大程度上,Segond 骨折或更广泛的 ALC 损伤会增加膝关节旋转不稳定性,这是一个正在研究的问题。因此,尚不确定未治疗的 Segond 骨折是否会对结果产生不利影响,因此是否需要考虑手术干预仍不确定。需要前瞻性随机研究解剖学前交叉韧带重建术,或是否同时治疗 Segond 骨折,以更明确地回答这些问题。
