Suture Bridge Fixation Technique for Posterior Cruciate Ligament Avulsion Fracture

Abstract

Avulsion fractures of posterior cruciate ligament (PCL) represent a specific form of PCL injuries. 1) Improper treatment of this injury results in an incompetent PCL that leads to knee instability and osteoarthritis. 2) ] Conventional techniques using direct posterior or posteromedial approach are widely used despite the potential risk of complication, such as damage to the neurovascular structure, tearing of the gastrocnemius muscle and scarring of the wound. Cancellous screws or cannulated screws are generally used for open reduction and internal fixation. 7) However, screw fixation is indicated only for the large and noncomminuted fragment. 7) Small or comminuted fragments are difficult to fix; in addition, there is a potential risk of fragmentation of the fracture fragment. In this study, we introduced a surgical technique, consisting of open reduction using posteromedial approach and internal fixation with suture bridge technique for tibial avulsion fracture of the PCL.
