    IntroductionHigh energy tibial plateau fractures are fraught with complications, particularly fracture-related infection (FRI). Previous studies have evaluated patient demographics, fracture classification, and injury characteristics as risk factors for FRI in patients with these injuries. This study evaluated the relationship between radiographic parameters (fracture length relative to femoral condyle width (FLF ratio), initial femoral displacement (FD ratio), and tibial widening (TW ratio)) and fracture-related infection following internal fixation in high energy bicondylar tibial plateau fractures.Methods225 patients treated for bicondylar tibial plateau fractures at two level I trauma centers were retrospectively reviewed. Patient characteristics, fracture classification, and radiographic measurements were analyzed to determine association with FRI.ResultsThe rate of FRI was 13.8%. Increased fracture length, FLF ratio, FD ratio, TW ratio, and fibula fracture were each associated with FRI on regression analysis, independent of clinical variables. Cutoff values were identified for each parameter and patients were risk stratified based on these radiographic parameters. High-risk patients had a 2.68- and 12.36-times risk of FRI compared to medium and low-risk patients, respectively.DiscussionThis study is the first to examine the relationship between radiographic parameters and FRI in high energy bicondylar tibial plateau fractures. Fracture length, FLF ratio, FD ratio, TW ratio, and fibula fracture were identified as radiographic parameters associated with FRI. More importantly, risk stratifying patients based on these parameters accurately identified patients at increased risk of FRI. Not all bicondylar tibial plateau fractures are created equal and radiographic parameters can be utilized to help identify the bad actors.Copyright © 2023. Published by Elsevier Ltd.
