Anterior cruciate ligament injuries are very commonly encountered during routine MRI reporting and various signs have been described for their identification. However, the diagnosis of isolated bundle tears is difficult using MRI, thus can be easily overlooked, especially isolated tear of posterolateral bundle. We present a case of a young male with "Gap" and "Footprint" signs on MRI knee joint, which are considered highly specific of posterolateral ACL bundle tear.
前交叉韧带损伤在常规MRI报告中非常常见，并且已经描述了用于识别它们的各种征象。然而，使用MRI诊断孤立的束带撕裂很困难，因此很容易被忽视，尤其是后外侧束带的孤立撕裂。我们报告一例年轻男性病例，其膝关节MRI显示有“间隙”和“足迹”征，这些征象被认为是后外侧前交叉韧带束带撕裂的高度特异性表现。
