Abstract

A 35-year-old man presented with right knee pain following a tree stump landing on his leg two days prior. Evaluation revealed a knee dislocation injury (KD III M) with displaced avulsion fractures of the anterior cruciate ligament and posterior cruciate ligament, with the fragments flipped 180 degrees. Additional injuries identified through preoperative imaging (computer tomography, magnetic resonance imaging) and physical examination included bony medial patellofemoral ligament tear, bony posterolateral corner injury, complete medial collateral ligament tear, and medial/lateral meniscus root bony avulsions. The injury was treated utilizing a single-staged arthroscopic and open ligament repair and reconstruction. Bicruciate avulsion fractures in the setting of a knee dislocation injury is a challenging surgical problem in which arthroscopic management of bicruciate tibial spine injuries can be utilized successfully.
