However, it is unknown how differences in harvest location of the QT affect its thickness and cross\u2010sectional area (CSA). The present study aimed to clarify the differences in thickness and CSA of the QT based on location of tendon harvesting.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Patients scheduled for, or who underwent, ACL reconstruction were prospectively included in the study. The short\u2010axis images on ultrasound were used to assess the CSA of the QT at 30 and 60\u00a0mm proximal to the superior pole of the patella. QT autografts with CSAs greater than or equal to 10\u00a0mm of width were included and measured at three different locations, namely the center, medial one\u2010third, and lateral one\u2010third at the widest diameter of the QT. Patients with less than 10\u2010mm width of the QT at 60\u00a0mm proximal to the superior pole of the patella were excluded. The thickness and CSA were compared based on the location of tendon harvest.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Thirty\u2010seven patients were recruited for the study. The mean thickness and CSA were larger in the center of the QT compared to the lateral one\u2010third at 30\u00a0mm proximal to the superior pole of the patella (thickness, 6.7\u2009\u00b1\u20091.3\u00a0mm vs. 5.9\u2009\u00b1\u20091.3\u00a0mm; <jats:italic>P<\/jats:italic>\u2009=\u20090.009; CSA, 65.6\u2009\u00b1\u200911.4\u00a0mm<jats:sup>2<\/jats:sup> vs. 58.8\u2009\u00b1\u200911.9\u00a0mm<jats:sup>2<\/jats:sup>; <jats:italic>P<\/jats:italic>\u2009=\u20090.036). There were no significant differences in thickness and CSA of the QT among the three assessment locations at 60\u00a0mm proximal to the superior pole of the patella (n.s.).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The thickness and CSA of QT was greater in the center compared to the lateral one\u2010third at 30\u00a0mm proximal to the QT insertion point. However, the difference in value was clinically non\u2010significant, and therefore, harvest location of the QT autograft may not meaningfully impact intraoperative graft diameter. As a result, surgeons may choose the harvest location without concern for resultant graft diameter as long as the enough length of QT is secured.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of
