The purpose of this article is to review the clinical importance and MRI appearances of injuries to the posterolateral corner of the knee.
Injuries to the posterolateral corner structures of the knee can cause significant disability due to instability, cartilage degeneration, and cruciate graft failure. Becoming familiar with the anatomy of this region can improve one's ability to detect subtle abnormalities and can perhaps lead to improvements in diagnosing and understanding injuries to this area.
本文旨在综述膝关节后外侧角损伤的临床重要性及磁共振成像（MRI）表现。
膝关节后外侧角结构损伤可因不稳定、软骨退变和交叉韧带移植失败而导致严重残疾。熟悉该区域的解剖结构可提高检测细微异常的能力，并可能有助于改进对该区域损伤的诊断和理解。
