The anterior cruciate ligament (ACL) is one of the main stabilizers in the knee, and in its absence it may lead to an increased risk of damage to other intra-articular structures. The presence of concomitant meniscus tears in patients with ACL injuries has been reported to cause a significant increase in the incidence of osteoarthritis. The incidence of meniscus lesions accompanying ACL injuries have been reported to be up to 43% in the literature. There is a classical literature on lateral meniscus tears are more common in acute ACL injuries and medial meniscus tears in chronic ACL tears. However, there are also studies reporting that medial meniscus tears accompany acute ACL injury more. The most common type of tear has been shown to be a longitudinal tear in both the medial and lateral meniscus. It has been reported that incomplete tears are more common in the lateral meniscus. As the localization of the meniscus tear, it is reported that it is most frequently located in the posterior part of the medial meniscus, close to the meniscocapsular junction. Ramp lesion, defined as peripheral detachment lesion of posterior horn of medial meniscus. The most important feature of this difficult to detect and clinically important lesion is that it often accompanies ACL tears. It is more common in chronic ACL ruptures than acute injuries. External rotational instability and anterior tibial translation significantly increase in the knee in the presence of a ramp lesion. It has been reported that repair will be a better treatment option in these tears. Because of its very close to the saphenous neurovascular bundle, it is important to preserve these structures during repair. The increase in age, the time from injury, the increase of male sex and body mass index increase the risk of meniscus tears. Repair of meniscus tears accompanying ACL injury in its treatment has become a standard procedure.
