The median age was 21 years, and the median follow\u2010up was 34.5\u00a0months. Reconstruction was performed using a hamstring autograft fixed with two suture anchors at native patellar site of the MPFL. No patient had undergone additional medial tibial tuberosity transfer. Clinical scores (Kujala, Lysholm, and Tegner score) and apprehension test were completed preoperatively and at the follow\u2010up. Preoperative and follow\u2010up radiographic assessments included modified Insall\u2010Salvati ratio, congruence angle, and lateral patellofemoral angle.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The preoperative Kujala and Lysholm scores were 52.6 \u00b1 12.4 and 49.2 \u00b1 10.7, and at follow\u2010up visits, corresponding values were 90.9 \u00b1 4.5 (<jats:italic>p<\/jats:italic> &lt; 0.001) and 90.9 \u00b1 5.2 (<jats:italic>p<\/jats:italic> &lt; 0.001). Tegner score increased from 3.0 (range 1\u20134) to 5.0 (range 4\u20137) (<jats:italic>p<\/jats:italic> &lt; 0.001). The apprehension test was positive in all patients preoperatively, but only positive in one patient at follow\u2010up. All radiographic assessments were significantly improved; modified Insall\u2010Salvati index (from 1.75 to 1.65) (<jats:italic>p<\/jats:italic> = 0.002), congruence angle (from 6.3\u00b0 to \u22127.0\u00b0) (<jats:italic>p<\/jats:italic> &lt; 0.001), and lateral patellofemoral angle (from 2.1\u00b0 to 4.9\u00b0) (<jats:italic>p<\/jats:italic> = 0.008).
