Comparison of outcome of tibial avulsion fracture of the posterior cruciate ligament using open reduction internal fixation by cc screw and arthroscopic suture bridge technique

Abstract

Introduction: Number of operative techniques have been described with the use of lag screws, steel wires, arthroscopic tight rope fixation, arthroscopic suture bridge technique. As there is continuous advancement in newer technique, we are comparing outcome of PCL tibial avulsion fixed by two different methods open reduction internal fixation by CC screw and arthroscopic suture bridge technique. Method: The PCL tibial avulsion was approached by posterior Burks and Schaffer approach, fixed by CC screw in half of the patient and in another half, we used arthroscopic suture bridge technique. One fiber wire is used in arthroscopic technique. Results: Anatomical reduction and fixation of PCL avulsion by arthroscopic fixation is equally effective when compared with ORIF by CC screw fixation. Conclusion: The use of CC screw could be a simple and reliable technique for PCL avulsion fractures of the tibia. Patients achieved good knee function after surgery, but arthroscopic suture bridge technique of PCL avulsion fixation gives better knee function and less intraoperative complications.
