Radiol Clin North Am. 2018 Nov;56(6):935-951. doi: 10.1016/j.rcl.2018.06.006. Epub 2018 Sep 17.

Abstract

The posterolateral corner (PLC) of the knee is composed of numerous ligamentous and tendinous structures that provide restraint and stability. This anatomy is complex, and at times controversial. We present a comprehensive review of the normal anatomy and pathology of the PLC. We highlight potential pitfalls of image interpretation and detail what the referring physician needs to know.

Keywords: Arcuate ligament; Biceps femoris; Fabellofibular ligament; Fibular collateral ligament; Lateral collateral ligament; Popliteofibular ligament; Popliteus; Posterolateral corner.
