Classification, diagnosis, and treatment system of posteromedial structure and posterolateral corner injury in knee dislocation

To review the research progress of diagnosis and treatment system for knee dislocation (KD) based on the stage and classification of posteromedial structure and posterolateral corner injury, so as to provide guidance for clinical work. The relevant literature on the classification, diagnosis and treatment was extensively reviewed. At present, the criterion of the stage and classification of KD mainly include classification based on the size of the injury energy, Kennedy classification, and the improved Schenck classification, but they are not perfect because of no stage and classification of multiple ligament injury and no standardized treatment of different injuries. Hua Xi Knee Dislocation and Multiple Ligament Injury (HX-KDMLI) has optimum plan for injury treatment of posteromedial structure and posterolateral corner injury in KD based on stage and classification. At present, there is no unified opinion on stages and classifications of the posteromedial structure and posterolateral corner injury in KD as w
