 Fig. 1 | Fig. 1 Anteroposterior radiograph of the left knee, made after the injury, demonstrating a comminuted fracture of the proximal part of the tibia and depression of the lateral plateau. For larger view place cursor on image | |||||||||
 Fig. 2 | Fig. 2 Lateral radiograph of the left knee, made after the injury, demonstrating comminution, depression, and increased posterior slope of both the medial plateau and the lateral plateau. For larger view place cursor on image | |||||||||
 Fig. 3 | Fig. 3 Computerized axial tomographic scan, made through the proximal part of the tibia, showing the extent of articular involvement of the fracture. More than one-third of the medial plateau and two-thirds of the lateral plateau are involved. For larger view place cursor on image | |||||||||

| Radiographs revealed a fracture that involved the posterior aspect of both the medial and the lateral tibial plateau (Figs. 1 and 2). Computerized axial tomographic scans showed fracture lines in the coronal plane involving more than one-third of the medial plateau and two-thirds of the lateral plateau (Fig. 3). Coronal computerized tomographic reconstructions showed approximately 1 cm of depression of the lateral plateau with less displacement medially (Figs. 4 and 5). | ||||||||||
