The article is a review of literature sources devoted to the problems of treatment of chronic posterolateral rotational instability of the knee joint. The article briefly describes the anatomy and biomechanics of the main structures of the posterolateral angle, various points of view on their structure and function. The evolution of approaches to surgical restoration of the posterolateral angle since the 1970s is presented below. Modern methods of open, minimally invasive and arthroscopic techniques of anatomical and non-anatomical surgery of the popliteal tendon, lig.popliteofibulare and lig.collaterale fibulare are briefly described. This article reflects the main problems and, according to the authors, topical issues of the need to use a particular method of knee stabilization, depending on the severity of posterolateral instability and the clinical picture.
