Abstract
BACKGROUND: Reconstruction of the extensor mechanism after resection of the proximal tibia is challenging, and several surgical procedures are available. The purpose of this study was to determine the outcome of the fibular transposition technique for reconstruction of the extensor mechanism of the knee after proximal tibial resection. METHODS: We retrospectively reviewed five consecutive patients who underwent resection of the proximal tibia with prosthetic reconstruction and reconstruction of the extensor using fibular transposition between 1997 and 2011. There were two female and three male patients with a mean age of 50years (range, 27 to 76years). A follow-up evaluation included both passive and active range of motion, extensor lag, the MSTS score and complications. RESULTS: Patients were followed up for 93months (range, 44 to 160months). The mean extensor lag and active flexion were four degrees (range, 0 to 10°) and 103° (range, 85 to 110°), respectively. The mean MSTS score was 80% (range, 73 to 90%). All patients were able to ambulate without crutches at the latest follow-up. CONCLUSIONS: The utilization of the fibular transposition technique is a simple, reliable, and successful procedure for extensor reconstruction after proximal tibial resection.
