Abstract:
This report presents a rare case of a dislocated tibial plateau fracture. The patient sustained a closed fracture of the tibial plateau following a traffic accident, exhibiting a fracture pattern not fitting into any existing classification of tibial plateau fractures. Preoperative imaging revealed a lateral plateau fracture with medial dislocation of the knee joint and entrapment of the medial meniscus within the gap. The injury mechanism is hypothesized to involve external and internal rotation of the tibia relative to the femur, occurring during neutral or hyperextended positions of the knee joint. The patient's knee joint X-ray showed a fracture line passing through the lateral plateau, accompanied by medial dislocation of the knee joint, which mirrored the imaging of a Schatzker Type IV fracture dislocation caused by the classic mechanism of flexion varus and internal rotation. Hence, it was designated as a "reverse Schatzker type IV" tibial plateau fracture. Open reduction and internal fixation were performed on the 8th day post-injury, followed by knee joint stabilization with a hinge brace and guided functional exercises. Six months post-surgery, reevaluation indicated complete fracture healing and a knee flexion-extension range of 125°-5°.
