A 54-year-old male patient sustained the tibial plateau fracture caused by bicycle accident (Schatzker V, AO/OTA 41.C1). The first preoperative X-rays in anteroposterior and lateral views (a) and CT-scans (b, c) showed the tibial plateau fractures of medial and lateral condyle and the slight collapse of the lateral articular surface. The second preoperative X-rays in anteroposterior and lateral views (d), CT scans (e), and 3D printing model (f, g) showed the widening of the tibial plateau, the collapse of the lateral articular surface, and the poor reduction of the medial plateau. The X-rays in anteroposterior and lateral views (h) after the revision surgery indicated the correction of the widening of the tibial plateau, the restoration of lateral articular surface, the satisfied reduction of the medial plateau, and the favorable internal fixation of the anterolateral and posteromedial plate. The functional appearance (i, j) at 30 months after the revision surgery showed that the nice healing of the wounds and the satisfactory function of THE knee joint
