Preoperative, intraoperative, and 6 and 24\u2010month postoperative kinematic analyses were carried out using the KiRA accelerometer and KT1000 arthrometer to look for residual anterolateral rotational instability and residual anteroposterior instability. Functional outcomes were measured with the single\u2010leg vertical jump test and the single\u2010leg hop test. Clinical outcomes were evaluated using the IKDC 2000, Lysholm, and Tegner scores.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A significant reduction in anterolateral rotational instability was detected with the patient under anesthesia (from 3\u2009\u00b1\u20091.2 to 1.1\u2009\u00b1\u20091.1\u00a0m\/s<jats:sup>2<\/jats:sup>; <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05) as well as with the patient awake (from 2.1\u2009\u00b1\u20090.8 to 0.7\u2009\u00b1\u20091.4\u00a0m\/s<jats:sup>2<\/jats:sup>; <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). A significant reduction in anteroposterior instability was only present under anesthesia (from 3.4\u2009\u00b1\u20091.9 to 2.1\u2009\u00b1\u20091.1\u00a0mm; <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05), while no difference was present without anesthesia (from 2.3\u2009\u00b1\u20091.1 to 1.6\u2009\u00b1\u20091\u00a0mm; n.s.). Postoperative analysis of knee laxity did not show any significant variation from the first to the last follow\u2010up.
