• ABSTRACT
    • Introduction In the present study, we aimed to compare the clinical and radiological results of the single lateral locking plate fixation method to the dual plate (DP) fixation method in cases of unstable bicondylar proximal tibial plateau fractures. Materials and methods Fifty-six patients managed surgically with internal fixation for unstable bicondylar tibial plateau fractures (UBTF) (Schatzker type V and type VI or Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association {AO/OTA} type 41-C) over 36 months from January 2017 to December 2020 were included in this prospective study. All the fractures were fixed surgically either using dual locking plates through double incisions (DP group) or with a single lateral locking plate (single plate {SP} group). All intraoperative and postoperative complications were assessed and recorded. Oxford Knee Score (OKS), Rasmussen's functional grading system, and Rasmussen's radiological scoring system were used to evaluate the functional and radiological outcomes. Result All of the patients were followed for at least 12 months. Twenty-six patients were fixed with a single lateral locking plate, and 30 patients were fixed with a double-incision dual locking plate. The mean Oxford Knee Score (OKS) was 43.24 ± 4.46 in the DP group and 42.7 ± 2.57 in the SP group (P = 0.544). The mean Rasmussen's functional score (RFS) score in the present study was 26.6 ± 2.21 in the DP group and 24.97 ± 3.92 in the SP group (P = 0.056). At the final follow-up, the mean Rasmussen's radiological score (RRS) was 9.06 ± 1.01 in the DP group and 8.1 ± 0.81 in the SP group (P = 0.0003). Conclusion There are no statistically significant differences in the functional outcomes between the two groups, but higher benefits were found in the radiological outcomes in the dual plating group as compared to single lateral locking plate group.
