Summary. The anterolateral ligament of the knee joint is an important stabilizer of the knee joint in relation tothe internal rotation of the tibia. The anterolateral ligament injuries accompany more than half of anterior cruciateligament ruptures and are associated with lateral meniscus damage.The aim of the study – evaluate the role of ultrasonography in visualizing the anterolateral ligament of the kneejoint, identifying its injuries, and improving understanding of its functional anatomy.Materials and methods of research. To analyze the world experience of ultrasonography of anterolateralcommunication on publications in scientific professional journals.Research results. Most researchers accept the normal form of the anterolateral ligament as a fibrillaranisotropic structure. An important reference point for the visualization of the anterolateral ligament is the inferiorlateral artery, which, together with the veins of the same name, is described by most researchers as deeper thanthe anterolateral ligament, or more precisely between it and the meniscus. The optimal flexion angle of the kneejoint at which the anterolateral ligament is best visualized and detected most often / most easily is not determined.Regarding the function of the anterolateral ligament, ultrasonographic studies confirmed its tension during flexionand internal rotation of the tibia.Promising and relevant is the solution of the possibility of ultrasonographically comparing the anterolateralligament on a damaged and healthy contralateral knee joint and expect that they should normally look the same,even if the frequency of detection of the anterolateral ligament in the right and left knee joints differs.Conclusions. Ultrasonographic studies of the anterolateral ligament are not only important from the perspectiveof diagnosing its damage, but have already complemented our understanding of its structure and function.
