Combined Lateral Plateau and PCL Injury in a Pediatric Patient: A Case Report

INTRODUCTION: Posterior cruciate ligament (PCL) injuries and tibial plateau fractures are common orthopedic injuries. In the pediatric population, femoral-sided avulsions are the most common injury pattern for PCL injuries. However, there is limited literature on the characterization and treatment of pediatric PCL avulsion with concomitant tibial plateau fracture. CASE REPORT: We present the case of an adolescent female who was involved in an all-terrain vehicle rollover. The patient sustained a femoral-sided PCL avulsion injury with an associated lateral tibial plateau fracture. The PCL avulsion was treated through arthroscopic cruciate repair, while the tibial plateau fracture was managed with open reduction and internal fixation (ORIF). CONCLUSION: This case report highlights a rare combination of a femoral-sided PCL avulsion and lateral tibial plateau fracture in a pediatric patient. The treatment involved arthroscopic cruciate repair for the PCL avulsion and ORIF for the tibial plateau fracture. Further studies are needed to establish optimal management strategies for similar cases.
