Fratura da espinha tibial: técnica artroscópica para tratamento e retensionamento do ligamento cruzado anterior

Abstract

Tibial spine fractures are defined as bony or chondral avulsions of the tibial plateau at the insertion point of the anterior cruciate ligament (ACL). The classic mechanisms of injury are forced knee flexion with simultaneous external rotation of the tibia, and the most common classification for these fractures was described by "Meyers and McKeevers" (MM), and later added subtype IV by "Zaricznyj", these classifications assist in clinical thinking for the treatment of tibial spine fractures. Some articles discuss arthroscopic techniques as the gold standard for these injuries. In this article, we present a case of a 42-year-old male patient who suffered a car accident due to a fall from a motorcycle with impact of the left knee to the ground, diagnosed with a comminuted tibial spine fracture, and treated surgically with the arthroscopic technique described in this article.
