Abstract
Background. Diagnostics and treatment of patients with chronic posterior and posterolateral instability of the knee is one of the most understudied problems of modern orthopedics. This is due to rather low frequency of this pathology, as well as to complex anatomy of tendoligamentous structures of the posterolateral part of the knee joint. Steadily increasing number of foreign publications dedicated to this topic say that there is no common approach to the tactics of surgical treatment of patients of this category at the moment.
Aim of review to evaluate the main trends of surgical treatment of this pathology according to the stage of involvement of various anatomical structures responsible for posterolateral rotational instability in the pathologic process.
Results. Despite a large number of methods of surgical treatment of posterolateral corner injuries, when analyzing modern publications, several main trends concerning posterolateral instability of the knee joint can be identified. In case of type 1 posterolateral instability, an isolated arthroscopic posterior cruciate ligament plasty is the most optimal. As for types 3 and 4, today such anatomical techniques as Larson and LaPrade have completely replaced the methods of non-anatomical reconstruction of the posterolateral corner. In addition, a large number of publications have recently appeared concerning arthroscopic techniques of these surgeries. The most important problem concerns the extent and the methods of surgical intervention in case of type 2 instability. Authors of the article consider that an arthroscopic posterior cruciate ligament plasty combined with popliteal tendon plasty is the most optimal for such category of patients.
Conclusion. The actual problem is the question of the method of surgical treatment in case of type 2 instability. The optimal technique for such patients is arthroscopic posterior cruciate ligament plasty combined with popliteal tendon plasty.
