| Summary: | Background: Pediatric isolated PCL avulsion from the tibial attachment is a rare occurrence.Although an isolated PCL lesion can be treated conservatively, it has shown poor results due to alteration in biomechanics.Surgical treatment restores the anatomy, reducing the incidence of osteoarthritis. Case report: We report a case of PCLavulsion fracture in an adolescent with open physis. We surgically fixed the ligament by passing a fiberwire through the substance of PCL and tied it over a suture disc anteriorly over the medial cortex of proximal tibia. At one year follow up, the fracture had united, and the patient regained full range of motion. Conclusion: Tibial sided avulsion fracture of PCL in children is an infrequent injury, with only a handful of cases reported. Fixation with a fiberwire and suture disc is a viable option for treating these injuries.
