The knee is an inherently unstable structure consisting of rounded femoral condyles articulating with a flat tibial plateau. Stability is provided by a complex system of intra-articular and extraarticular ligaments that resist anterior and posterior translation, abnormal tibial rotation, and varus and valgus stress. In this article, the anatomy and biomechanics of the medial and lateral stabilizers, as well as the mechanisms of injury, clinical examination, and radiographic and magnetic resonance imaging appearances of injury of these structures, are discussed.
膝关节本质上是一个不稳定的结构，由圆形的股骨髁与平坦的胫骨平台相连接组成。其稳定性由关节内和关节外韧带的复杂系统提供，这些韧带可抵抗前后移位、胫骨异常旋转以及内翻和外翻应力。本文将讨论内外侧稳定结构的解剖学和生物力学，以及这些结构损伤的机制、临床检查、影像学和磁共振成像表现。
