Evaluation with magnetic resonance imaging (MRI) is currently a gold standard for comprehensive posttraumatic assessment of the knee joint. Increasing availability of MR systems with stronger magnetic fields and new sequences results in higher resolution of images and thus allows imaging smaller and finer anatomical details, including different anatomical variations. This article focuses on anatomical variations of knee ligaments, which can mimics pathological structures. Well-known and less common ligaments that are sporadically observed and may raise the most doubt will be discussed. Familiarity with those variations of ligaments is indispensable for precise MRI reporting to avoid misinterpretation as meniscal tears, loose bodies or mass lesions especially in cases. This paper is addressed to both radiology and orthopaedics specialists. Illustrations show discussed ligaments in standard planes while, for less known ligaments, we add information on how to adjust planes to properly visualise a particular structure, which will hopefully facilitate finding and differentiating those structures in clinical practice.
磁共振成像（MRI）评估目前是膝关节创伤后综合评估的金标准。磁场更强的磁共振系统和新序列的日益普及，提高了图像分辨率，从而能够对更小、更精细的解剖细节进行成像，包括不同的解剖变异。本文重点关注膝关节韧带的解剖变异，这些变异可能会模仿病理结构。将讨论偶尔观察到的、可能引发最多疑问的知名和不太常见的韧带。熟悉这些韧带变异对于准确的MRI报告至关重要，以避免误诊为半月板撕裂、游离体或肿块病变，尤其是在某些病例中。本文面向放射科和骨科专家。插图展示了标准平面中的讨论韧带，而对于不太知名的韧带，我们补充了有关如何调整平面以正确显示特定结构的信息，希望这将有助于在临床实践中找到并区分这些结构。
