The intraclass correlation coefficient (ICC) and Bland\u2013Altman analysis were performed to evaluate the reliability of tibial tubercle\u2013trochlear groove (TT\u2013TG), tibial tubercle\u2013Roman arch (TT\u2013RA), and tibial tubercle\u2013posterior cruciate ligament (TT\u2013PCL) distance measurements. The values of CT and MRI measurements using the same bony landmarks were compared for the difference. Pearson correlation analysis and linear regression analysis were performed to assess the correlation between CT and MRI measurements.

TT\u2013TG distance measured on CT (19.5\u2009\u00b1\u20095.1\u00a0mm) had a mean of 7.1\u00a0mm higher than that on MRI (12.4\u2009\u00b1\u20094.7\u00a0mm) (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). The mean value of TT\u2013RA distance was 22.5\u2009\u00b1\u20093.7\u00a0mm on CT and 16.7\u2009\u00b1\u20094.9\u00a0mm on MRI (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001), showing a mean difference of 5.8\u00a0mm. The values of TT\u2013TG distance measured by CT and MRI were significantly correlated (<jats:italic>R<\/jats:italic>\u2009=\u20090.5, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). The values of TT\u2013RA distance between these two modalities showed a better correlation than that of TT\u2013TG distance (<jats:italic>R<\/jats:italic>\u2009=\u20090.6, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001).
