Effects of axial malrotation on posterior tibial slope measurement: a digitally reconstructed radiograph study enabling automated quality assessment

Key Points

• Axial malrotation significantly affects the accuracy of posterior tibial slope measurements.
• The study assessed the impact using digitally reconstructed radiographs, with notable quality variances.
• This retrospective cohort study highlighted the need for automated quality assessments for better accuracy.
• Findings suggest that adjustments in measurement practices may be necessary to account for axial malrotation.
