The length and thickness of the QT on preoperative magnetic resonance imaging (MRI) were compared with those measured under direct visualization. The ACL length was measured on preoperative MRI and three\u2010dimensional computed tomography after ACL reconstruction. The QT length on MRI was compared with the required graft length, and the factors related to an adequate QT length were assessed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The mean QT length on MRI was 60.8\u2009\u00b1\u20091.3\u00a0mm and was significantly positively correlated with the QT length under direct visualization (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.01).

Although the mean QT was 0.1\u00a0mm longer than the mean required graft length, the QT on MRI was shorter than the required graft length in 37% of patients (11\/30).
