Injuries of the medial collateral ligament (MCL) of the knee are easily diagnosed on clinical grounds. These lesions are generally treated conservatively. Radiological examinations are generally unhelpful. However, injuries of the MCL may be associated with those of many other ligaments of the knee in the case of complex strain of the knee so that the clinical diagnosis may be challenging; in some cases, surgical repair of associated lesions is indicated. In these cases of multiple ligamentous injuries, a radiological study of ligamentous abnormalities may be of interest. The anatomical background and the different radiological findings including those of X-rays, US, arthrography and MRI, obtained in patients with injuries of the MCL, are described; radiological differentiation of ruptures of the MCL with or without knee instability is emphasized.
膝关节内侧副韧带（MCL）损伤基于临床症状易于诊断。这些损伤一般采用保守治疗。放射学检查通常并无帮助。然而，在膝关节复杂拉伤的情况下，MCL损伤可能与膝关节许多其他韧带的损伤相关，因此临床诊断可能具有挑战性；在某些情况下，需要对相关损伤进行手术修复。在这些多发韧带损伤的病例中，对韧带异常进行放射学研究可能会有意义。本文描述了MCL损伤患者的解剖学背景以及包括X线、超声、关节造影和MRI在内的不同放射学表现；强调了伴有或不伴有膝关节不稳的MCL断裂的放射学鉴别。
