title: Posterior approach for arthroscopic reduction and antegrade fixation of avulsion fracture of the posterior cruciate ligament from the tibia with cannulated screw and washer.
abstract: Avulsion fracture of the posterior cruciate ligament (PCL) is a rare condition, and arthroscopically assisted reattachment of the surgical fixation of the fragment is not always an easy task. Only a few reports describe techniques for arthroscopic fixation of avulsion of the PCL.We report on a case treated arthroscopically with reduction and antegrade fixation of an avulsion fracture of the tibial attachment of the PCL with a cannulated screw and washer through an additional posterolateral portal. Postoperative morbidity was reduced, and rehabilitation was accelerated. Fixation with a cannulated screw and washer is technically simple and allows for stable fixation and immediate postoperative mobilization and pain-limited weight-bearing, even in cases of a comminuted fragment. The safe zone for an additional posterolateral portal and the technique for placing instruments and a guidewire to avoid neurovascular structures is defined.
