The inclusion criteria were patients aged from 15 to 50 years; patellar dislocation occurring 2 or more times; a Merchant view or computed tomography scan indicating patellofemoral joint malalignment, external patellar inclination, or lateral patellar dislocation; underwent MPFL reconstruction via robot\u2010assisted or traditional freehand technique; complete medical records and imaging data before and after surgery; and a minimum of 1\u2010year postoperative follow\u2010up. The operation duration, intraoperative number of fluoroscopies, hospitalization length, Kujala score, and Lysholm score were recorded. In addition, the Bisect offset index and the distance between the femoral tunnel and Sch\u00f6ttle point were measured based on preoperative and postoperative computed tomography data of each patient in the 2 groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The mean follow\u2010up times of the 2 groups were 27 \u00b1 8 months and 31 \u00b1 9 months, respectively (\n                      <jats:italic>P<\/jats:italic>\n                      = .05). Neither group of patients experienced patellar redislocation. The median number of fluoroscopies in the robot\u2010assisted group was 4.5 times lower than in the freehand group (9 times,\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .001). The distance between the femoral tunnel and Sch\u00f6ttle point in the robot\u2010assisted group was 2.57 \u00b1 0.97 mm, which was significantly shorter than the freehand group (5.58 \u00b1 2.92 mm,\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .001).

The Kujala and Lysholm scores were significantly improved postoperatively in the 2 groups. Specifically, the postoperative Kujala and Lysholm scores in the robot\u2010assisted group (89 and 89) were higher than the freehand group (85 and 84,\n                      <jats:italic>P<\/jats:italic>\n                      = .03 and\n                      <jats:italic>P<\/jats:italic>\n                      = .02). Moreover, the results also showed higher postoperative functional scores in the robot\u2010assisted group when the cases were divided into 1\u2010year and 2\u2010year groups. However, the cohort\u2010specific minimal clinically important difference analysis revealed no significant difference in the patient\u2010reported outcomes (Kujala and Lysholm scores) between the 2 groups.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Robot\u2010assisted MPFL reconstruction for recurrent patellar dislocation achieved higher accuracy of femoral tunnel and lower radiation exposure compared to the freehand technique.
