The anterior horn of the lateral meniscus attaches anteriorly to the lateral intercondylar spine and posteriorly to the anterior cruciate ligament attachment; the posterior horn attaches posteriorly to the lateral intercondylar spine. The meniscus is divided into the lateral meniscus and the medial meniscus, with the lateral meniscus being “O”-shaped and the medial meniscus being “C”-shaped. The lateral meniscus is smaller than the medial meniscus, and the anterior and posterior corners are attached to the anterior and posterior regions of the intercondylar spine of the tibia, the anterior corner of the anterior ligament being behind the anterior cruciate ligament, and the posterior corner of the posterior ligament being behind the posterior cruciate ligament. The posterior horn is located anterior to the attachment point of the posterior cruciate ligament. The lateral meniscus forms a deeper depression in the femoral condyle on the tibial plateau, increasing the stability of the spherical femoral condyle and tibial plateau, and the anterior and posterior horns mainly maintain the stability of the joint and the coordination of movement.
