Posterior root of lateral meniscus

The posterior horn of lateral meniscus is anchored to the tibia via the posterior root, which most commonly inserts at the posterior intertubercular area of the tibial plateau, just posteromedial to the tibial attachment of the anterior cruciate ligament (ACL), and may also have a secondary attachment to the posterior slope of the lateral tibial eminence. Variability exists, with single, double, or even triple root insertions observed in high-resolution imaging studies.
