Posterior cruciate avulsion fractures are not very common but among the avulsion fractures around the knee, PCL avulsions are very common followed by anterior cruciate ligament avulsion, various treatment modalities have been described in the literature right from non -operative treatment to operative treatment. Objective: To report the functional outcome of posterior cruciate ligament (PCL) tibial avulsion fracture treated with open reduction and internal fixation using CC screws through BURKS AND SCAHFFER approach. Material and Methods: A series of 20 patients having isolated PCL avulsion fractures at tibial attachment were selected for this study, 3 patients refused treatment by any means. 17 patients (12 male and 5 female) were included in the study with median age group of 28 years (19-45 years). All the patients were treated with ORIF with CC screws through burks and Schaffer approach all of them were followed up for the period of two years. And functional outcome was assessed using Lysholm knee scoring system. Results: Union was achieved in all the cases at the end of the study all patients were able to squat easily and extend the knee fully. Lysholm score was excellent in 13 patients and good in 3 patients
