We report 3 cases of AnteroMedial MeniscoFemoral Ligament (AMMFL) fortuitously demonstrated during knee imaging in three patients. This rare normal variant of insertion of the anterior horn of the medial meniscus consists of an anomalous fibrous band distinctly covering the whole length of the anterior cruciate ligament to attach the anterior horn of the medial meniscus to the posterolateral wall of the femoral intercondylar fossa. AMMFL was diagnosed during arthro-CT in two patients and clearly identified during knee MR imaging in a third patient. The two cases demonstrated during arthro-CT--one prospectively and the other retrospectively--were confirmed during therapeutic arthroscopy. We illustrate the anomaly, discuss its controversial clinical significance and review the literature.
我们报告了3例在膝关节成像过程中偶然发现的前内侧半月板股骨韧带（AMMFL）病例，这3例患者来自不同个体。这种内侧半月板前角附着的罕见正常变异结构由一条异常纤维带组成，该纤维带明显覆盖前交叉韧带的全长，将内侧半月板前角附着于股骨髁间窝的后外侧壁。2例患者在关节CT检查时诊断出AMMFL，第3例患者在膝关节磁共振成像时明确识别出AMMFL。在关节CT检查中发现的2例病例——1例为前瞻性发现，另1例为回顾性发现——在治疗性关节镜检查中得到证实。我们展示了这种异常结构，讨论了其存在争议的临床意义并回顾了相关文献。
