    Objectives: To compare outcomes and costs between locking and nonlocking constructs in the treatment of bicondylar tibial plateau (BTP) fractures. Design: Retrospective cohort study. Setting: Level 1 academic trauma center. Patients: All patients that presented with complete articular, BTP fractures (AO/OTA 41-C and Schatzker 6) between 2013-2015 were screened (n=112). Patients treated with a mode of fixation other than plate-and-screw were excluded. 56 patients with a minimum follow-up of 12 months were included in the analysis. Intervention: Operative fixation of BTP fractures with locking (n=29) or nonlocking (n=27) implants. Main outcome measurements: Implant cost, patient reported outcomes (PROMIS physical function and pain interference), clinical, and radiographic outcomes. Results: There were no differences between the two groups with respect to demographics, injury characteristics, radiographic outcomes (change in alignment) or clinical outcomes (PROMIS, reoperation, nonunion, infection). Implant costs were significantly greater in the locking group compared to the nonlocking group (mean L $4453; mean NL $2569; p<0.01). Conclusions: This study demonstrated improved value of treatment (less cost with no difference in clinical outcome) with nonlocking implants for bicondylar tibial plateau fractures when dual plate fixation strategies are performed. Level of Evidence: Therapeutic III. See Instructions for Authors for a complete description of levels of evidence.
