Lateral Meniscus, Posterior View

Description

Posteriorly, the lateral meniscus appears as a C-shaped fibrocartilaginous disk interposed between the lateral femoral condyle superiorly and the lateral tibial plateau inferiorly, with a conspicuous interval between its anterior horn and posterior horn. The posterior horn sits close to the intercondylar area of the tibia and lies anterior to the posterior joint capsule, while the body of the meniscus arcs laterally toward the fibular side of the joint. Surrounding context includes hyaline articular cartilage capping the femoral condyles and tibial plateau, with the fibular head positioned lateral and slightly posterior to the lateral tibial condyle. This is a knee view built for orientation. Posterior viewing makes the meniscal root attachments and posterior compartment relationships easier to teach, because you can relate the posterior horn position to the intercondylar region where cruciate ligament footprints cluster. Clinically, the lateral meniscus is frequently involved in acute twisting injuries and in association with anterior cruciate ligament rupture, and posterior horn tears or root avulsions can produce posterolateral joint line pain and mechanical symptoms that are missed if you only think in anterior terms. Arthroscopic planning depends on this anatomy, since access to the posterior horn and posterior root often requires posterolateral portals and careful awareness of the popliteus tendon corridor and nearby capsule. Orthopaedic surgery texts, sports medicine lectures, and gross anatomy practicals use this perspective to clarify why the lateral meniscus is more mobile than the medial meniscus and how that mobility changes tear patterns. Radiology teaching files can pair the posterior view with coronal MRI to correlate the posterior horn, root, and articular cartilage surfaces when discussing meniscal extrusion and postoperative meniscectomy findings.
