Correlation Between Radiographic and MRI Posterior Tibial Slope Measurement on a Pediatric Population.

ABSTRACT: Background/Objectives: Posterior tibial slope (PTS) is an established risk factor for anterior cruciate ligament (ACL) injury in adults. In pediatric population, this relation is less established, and the PTS measurement is not clearly defined. To determine the agreement between X-ray (XR) and magnetic resonance imaging (MRI) PTS measurements and to establish an MRI cutoff corresponding to the standard radiographic ≥12° definition of "high slope". Methods: In this retrospective study, 108 adolescent knees with ACL rupture underwent paired XR and MRI evaluation by two reviewers. Agreement was assessed with Pearson and Spearman correlation, intraclass correlation coefficient (ICC), Bland-Altman analysis, and Deming regression. Diagnostic performance of MRI thresholds was compar
