Objective: To report the functional outcome in Posterior Cruciate Ligament (PCL) tibial avulsion fractures treated with open reduction and internal fixation with cancellous screw fixation through the posteromedial approach.

Materials and Methods: This is a prospective and retrospective study conducted in Katuri medical college and hospital, Guntur, from September 2016 to May 2019. Total eight number of patients who came with White's type 2 & 3 displaced Posterior Cruciate Ligament (PCL) tibial avulsion fractures treated by open fixation with cancellous screws through the posteromedial approach. The pre-operative assessment was done with a magnetic resonance imaging for all the patients to confirm the fracture.

Results: Post-operative radiographs were taken, which showed all avulsed fragments are well reduced and maintained. In all the cases, healing was evident by the end of 3 months. There are no symptoms of instability found clinically. The average Lysholm knee score was 94.3 (84-97).

Conclusion: This study demonstrated treatment of White’s type 2 & 3 displaced avulsion fracture of the posterior cruciate ligament by open reduction through the posteromedial approach and internal fixation using partially threaded screws gives very good functional and radiological results.
