Outcome measures were compared based on the Insall\u2013Salvati index.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Patients who were diagnosed with recurrent patellar dislocation and underwent either MPFL\u2010R or MPFC\u2010R (combined reconstruction of MPFL and medial quadriceps tendon\u2010femoral ligament) were retrospectively analyzed. Group allocation was based on surgical procedure and patient characteristics were collected. Clinical assessments included patient\u2010reported outcome measures (PROMs) and return\u2010to\u2010sports rates. Minimal clinically important difference analysis was performed. A subgroup analysis of PROMs was carried out between patients with an Insall\u2013Salvati index \u22641.2 versus &gt;1.2. The patellar tilt angle, lateral patellar displacement, and bisect offset ratio were measured pre\u2010 and postsurgery. Functional failures and complications were assessed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Overall, 70 patients (72 knees) in the MPFL\u2010R group and 58 patients (61 knees) in the MPFC\u2010R group were included. Patient characteristics were comparable between the groups. At a minimum follow\u2010up of 24 (mean, 50.6 \u00b1 22.1) months, all PROMs were substantially improved (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .001), without significant intergroup differences. The percentages of patients reaching the minimal clinically important difference were similar after MPFL\u2010R and MPFC\u2010R: 98.6% versus 93.4% (International Knee Documentation Committee), 97.2% versus 98.4% (Lysholm), 98.6% versus 100% (Kujala), and 77.8% versus 72.1% (Tegner). The subgroup analysis based on patellar height and the return\u2010to\u2010sport rates also suggested comparable results. Radiographic evaluation demonstrated significantly smaller lateral patellar displacements (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .004) and bisect offset ratios (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .001) but similar patellar tilt angles after MPFC\u2010R. Four (5.6%) patients receiving MPFL\u2010R and 2 (3.3%) patients receiving MPFC\u2010R reported recurrence of functional instability, without statistically significant difference.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>MPFC\u2010R resulted in similar overall clinical and radiographic outcomes to MPFL\u2010R in treating recurrent patellar dislocation.
