Magnetic resonance imaging (MRI) is now the modality of choice for the investigation of internal derangement of the knee. Technological advances, including the wider availability of stronger magnets and new sequences, allows improved visualisation of smaller structures. Normal variants must be recognised as such, so that both over-investigation and mis-diagnosis are avoided. This article reviews both the well-recognised and the less common ligamentous and musculotendinous anatomical variants within the knee and illustrates their imaging characteristics on MRI.
磁共振成像（MRI）现在是膝关节内部紊乱的首选检查方式。技术进步，包括更广泛地使用更强的磁铁和新序列，使得更小结构的可视化得到改善。必须将正常变异识别为正常变异，以避免过度检查和误诊。本文综述了膝关节内的韧带和肌肉肌腱解剖变异，包括常见的和不常见的，并说明了它们在 MRI 上的影像学特征。
