The Anterolateral Ligament of the Knee: MRI Appearance, Association With the Segond Fracture, and Historical Perspective

摘要

OBJECTIVE. A recent publication has drawn attention to the anterolateral ligament, a structure of the knee with which most radiologists are unfamiliar. We evaluate this structure on MRI; clarify its origin, insertion, meniscal relationship, and morphologic appearance; and identify its relationship with the Segond fracture.
