Four different methods were performed to take measurements of the tibiofibular interval using an axial computed tomography (CT) scan under existing arthroscopic diagnosis. Three previously reported parameters were assessed at 1\u00a0cm above the joint level. In the first method, 2\u00a0measurements were obtained. The anterior measurement was the closest distance between the anterior border of the fibula and anterior tibial tubercle. The posterior measurement was the closest distance between the medial border of the fibula and posterior tibial tubercle. In the second method, an angle between the fibular axis and the line connecting the anterior and posterior tibial tubercle was measured. In the third method, the nearest distance between the line perpendicular to the line connecting the tubercles at the anterior tubercle of the distal tibia and the anterior\u2010most margin of the fibula was measured. The fourth method, which was developed in this study, measured the narrowest tibiofibular distance at the joint level. Data were analyzed using Student's\n                      <jats:italic>t<\/jats:italic>\n                      \u2010test and the receiver operating characteristic curve to make comparisons among 4 CT\u2010based parameters.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In the comparison between the patients with arthroscopic diastasis and without diastasis, the posterior parameter in the first method and the narrowest tibiofibular distance at the joint level in the fourth method showed a significant difference (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .05) The areas under the receiver operating characteristic curve (AUCs) of the anterior and posterior parameter of the first method were 0.58 (95% confidence interval [CI], 0.43\u20100.73;\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .167) of anterior measurement and 0.6 (95% CI, 0.45\u20100.75;\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .029) of posterior measurement, respectively.
