Background: Tibial plateau fractures are one of the commonest intra-articular fractures resulting from indirect coronal or direct axial compressive forces. This study aimed to compare the functional outcome and the complication rate between Double-plate and single lateral locked in patients with bicondylar tibial plateau fractures. Patients and Methods: A prospective study was conducted in Zagazig university hospitals, in the period from August 2021 to February 2022, 18 patients complaining of tibial plateau fracture either Schatzker type V or VI were Included, divided into two groups; the Single lateral plate group which include nine patients. And the Double plate group which also included nine patients. Majority of the patients were males in both groups. The RTA was the leading cause of fracture in SLP group. While FFH was the most common cause of fracture in DP group. Anteroposterior and lateral radiographs of whole tibia from knee to ankle were obtained. CT scans were done for all cases to accurately delineate fracture type and extent, fragment size and location, the degree of articular depression or displacement. The clinical evaluation was based on Rasmussen scoring system with six months follow-up. Results: Rasmussen functional score showed significant improvement from the 1st month till the 6th month. There were no significant differences between the two methods with respect to functional and radiographic outcomes at the final follow-up. Also, both methods had no differences in complication rate. Conclusion: Both methods (single lateral plate and double plating) are effective methods for treatment of bicondylar tibial plateau fractures.
