Neurologic and Vascular Injuries Associated With Knee Ligament Injuries

Background: Multiple ligament knee injuries are commonly associated with neurovascular complications such as popliteal artery, common peroneal nerve, and tibial nerve injuries. Hypothesis: While the importance of identifying these complications in association with bicruciate and triligamentous injuries has been well established, it is important to recognize that any biligamentous and some single ligament knee injuries present with neurological and vascular complications as well. Study Design: Literature review. Conclusion: Popliteal artery injuries require immediate intervention to help prevent limb loss. Peroneal and tibial nerve injuries can be a significant cause of morbidity and, therefore, require an understanding of their natural history, anatomy, and pathophysiologic implications to maximize functionality. Clinical Relevance: This review explores the types, mechanisms, and classifications of common neurovascular complications of knee ligament injuries, discusses their diagnosis, and reviews the therapeutic options available to optimize patient outcomes.
