APEX Foundations in Arthroscopy Basic Lectures-Multiligament Knee Injuries and Dislocations: An Update

Video Transcription

Video Summary

In this video, the speaker discusses multiligament knee injuries and dislocations. They explain that a multiligament knee injury is a tear of at least two of the four major knee ligament structures. The speaker mentions that knee dislocations always result in multiligament knee injuries, but not all multilig injuries are knee dislocations. The incidence of these injuries is not very common unless at a level one trauma center. About a third of them are due to sports injuries. The speaker also discusses the types of multiligament knee injuries and knee dislocations, including high energy, low energy, and ultra-low energy. They emphasize that ultra-low energy injuries in morbidly obese patients are more at risk and can result in amputations if untreated. The speaker covers various classifications of these injuries, presentation, associated injuries, evaluation, and treatment options. They suggest single-stage surgery somewhere between two and six weeks after the injury. The speaker concludes the video with a case study of a professional football player who had multiple torn structures in his knee and underwent surgery to reconstruct the fibular collateral ligament, popliteus, and popliteal fibular ligament, as well as repair the biceps femoris and replace the ACL with an autograft bone patellar tendon.
