Large Individual Bilateral Differences in Tibial Torsion Impact Accurate Contralateral Templating and the Evaluation of Rotational Malalignment

Objective: To determine individual bilateral differences (IBDs) in tibial torsion in a diverse population. Methods: Computed tomography scans of uninjured bilateral tibiae were used to determine tibial torsion and IBDs in torsion using 4 measurement methods. Age, sex, and self-identified race/ethnicity were also recorded for each subject. Mean tibial torsion and IBDs in torsion were compared in the overall cohort and when stratified by sex and race/ethnicity. Simple and multiple linear regression models were used to correlate demographic variables with tibial torsion and IBDs in torsion. Results: One hundred ninety-five patients were evaluated. The mean tibial torsion was 27.5 ± 8.3 degrees (range −3 to 47.5 degrees). The mean IBD in torsion was 5.3 ± 4.0 degrees (range 0–23.5 degrees, P
