A combined anterolateral and posterior medial incision is made, with the posterior medial incision making a longitudinal incision from the medial tibia to the goose foot and exposing the fracture end from the posterior side of the goose foot. The anterolateral incision is made from the lateral edge of the patella to the midpoint of the line connecting the anterior border of the fibular tuberosity to the lateral edge of the tibial tuberosity and extends downward along the lateral tibial crest, and the joint capsule is incised and the meniscus is pulled apart with a meniscal pulling hook to expose the fracture end of the lateral plateau and the joint surface. During surgery, care was taken to avoid stripping the anterior tibial region where the blood supply was poor. The meniscus and ligament injuries were routinely explored intraoperatively. Through a posterior medial incision, the medial tibial plateau fracture end was exposed and repositioned, and fixed with an LC-DCP reconstruction plate to restore the medial column force line. After exposing the articular surface and fracture end of the lateral plateau through the anterolateral incision, the articular surface was repositioned under direct vision by prying with a bone knife or striker, and the joint surface was restored to a flat level and then temporarily fixed with a Kirschner pin, and the bone defect under the articular surface was fixed with an autogenous iliac bone or an allogeneic homograft bone graft. After the surgery, negative pressure drainage sutures were placed in the lateral incision.
