Preoperatively and at follow\u2010up, the patellar position and rotation were evaluated by computed tomography with the congruence angle, lateral patellar angle, patellar tilt angle, and lateral patellar translation; the subjective symptoms and functional outcomes were evaluated with Kujala, Lysholm, Tegner, and International Knee Documentation Committee subjective scores. Clinical examinations were also performed, and redislocations or episodes of instability were recorded.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Patients were followed up for a mean period of 41.11 \u00b1 7.40\u00a0months (range, 29\u201062\u00a0months). At the final point, no recurrent patellar dislocations occurred, except in 4 patients with instability symptoms in group A; however, no significant difference between the 2 groups was seen (\u03c7\n                      <jats:sup>2<\/jats:sup>\n                      \u00a0= 2.503,\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .114).
