Symptomatic Nonunion After a Tibial-Sided Posterior Cruciate Ligament Avulsion Fracture Treated with Open Repair

Abstract

Case: A 30-year-old man was in a motorcycle accident resulting in an avulsion fracture of the tibial insertion of the posterior cruciate ligament (PCL). After 19 months of nonoperative treatment, the patient presented with a nonunion and symptoms of pain and instability. He was treated with an open repair with screw fixation through a posterior approach. Six months postoperatively, the patient returned to his work as a heavy laborer with full range of motion and no instability. Conclusion: PCL avulsion fracture nonunion results in symptoms of swelling, pain, and instability. These symptoms can be treated with screw fixation through a posterior approach.
