Abstract:
We have experienced 3 cases of comparatively rare anteromedial meniscofemoral ligament in which the anterior horn of the medial meniscus was attached to the posterolateral wall of the femoral intercondylar fossa. In 2 of these cases, there was no attachment to the tibia, whereas in the other, it was connected to the lateral meniscus and also firmly to the tibia. In the 2 with no attachment to the tibia, abnormal mobility in the medial meniscus accompanied by flexion and extension of the knee was observed. Degeneration of the intermediate posterior segment and injury of the anterior horn were also observed. This anomaly induces a future meniscus injury, depending on the attachment state to the tibia.
