A typical case of a 42-year-old female with Schatzker IV tibial plateau fractures (hyperextension-varus-internal rotation type). (a) The features of this type were shown in CT images. (b) Preoperative hyperextension deformity suggested posterolateral instability of the knee joint. (c) The knee should be placed in flexion during the operation. (d) After restoring the compressed articular surface, two plates were needed for internal fixation. The avulsion fracture of the fibular head was fixed by rivets or wires. (e) 1 year postoperatively, the stability and function of the knee were good
