86 patients with bicondylar tibial plateau fracture with a relatively intact medial tibial condyle were randomized to receive surgical treatment with either a single lateral locking plate (LP) or dual buttress plates (DP). The purpose of this study was to compare clinical and radiographical outcomes between fixation methods over a minimum of 12 months postoperatively. While the incidence of delayed union was significantly lower in the LP group compared to the DP group, no patient experienced non-union. All other clinical, functional and radiographic outcomes were similar between groups, as well as the incidence of infection. Surgical parameters, such as operative time, blood loss, and hospital stay, were better in the LP group compared to the DP group.
