The anterior aspect of the knee is host to an array of normal variants and potential pathology. These normal anatomic variants are often encountered and may mimic pathologies, leading to unnecessary work-up and treatments. On the other hand, there are several subtle abnormalities that may be easily overlooked or mistaken for variants or other injuries or diseases. Recognition of these diagnostic challenges is essential for radiologists to make an accurate diagnosis. This article reviews normal anatomical variants of ligaments, tendons, bones, and other important structures of the anterior knee, focusing on magnetic resonance imaging features. Commonly encountered injuries and abnormalities of the anterior knee and their diagnostic pitfalls are also discussed, highlighting findings on magnetic resonance imaging.
膝关节前部存在一系列正常变异和潜在病变。这些正常解剖变异经常遇到，可能会模仿病变，导致不必要的检查和治疗。另一方面，有一些细微的异常可能很容易被忽视或误认为是变异或其他损伤或疾病。认识到这些诊断挑战对于放射科医生做出准确诊断至关重要。本文回顾了膝关节前部韧带、肌腱、骨骼和其他重要结构的正常解剖变异，重点关注磁共振成像特征。还讨论了膝关节前部常见的损伤和异常及其诊断陷阱，突出了磁共振成像的表现。
