Improvement of surgical treatment of patients with posttraumatic posterior-lateral instability of the knee joint

One of the most pressing and complex problems of modern orthopedics is the treatment of patients with multiligamentary knee injury. The most difficult category of patients is considered, in whom, along with rupture of one or both cruciate ligaments, damage to the ligamentous-tendon complex, which provides posterolateral stability of the knee joint, occurs. These structures, which have received the name posterolateral angle of the knee joint in the specialized scientific literature, usually include the peroneal collateral ligament, the hamstring of the popliteal muscle and the peroneal-popliteal ligament. Objective difficulties in the reconstruction of these elements are explained by the complexity of the anatomy and biomechanics of these anatomical structures, the polymorphism of their injuries, the proximity of the common peroneal nerve, as well as the shortcomings of the available plastic methods and the lack of generally accepted surgical tactics. Lack of applied precision data on the structure of the peroneal collateral ligament and the ligamentous-tendinous complex, called the postero-lateral angle of the knee joint in the specialized literature, analyzed from the standpoint of substantiating rational surgical tactics for treating patients with varus instability in combination with a large number of unsatisfactory results of their surgical treatment, determined the relevance of the topic of the chosen work (2 figures, bibliography: 17 refs).
