Finally, 25 cases, with the mean age of 8.4\u2009years (range from 7 to 10\u2009years), were admitted to the study. All patients were diagnosed as bilateral recurrent patellar dislocation associated with femoral trochlear dysplasia. The knee that suffered injury or was dislocated was treated with medial patellar retinacular plasty (surgery group). The contralateral knee, which served as a control, was treated conservatively (conservative group). Axial CT scans were undertaken in all patients to assess the patellar morphological characteristics.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The mean follow\u2010up time was 60.8\u2009months (range 48 to 75\u00a0months). Preoperatively, there were no statistically significant differences between the patellar morphology in the two groups (<jats:italic>P<\/jats:italic>\u2009&gt;\u20090.05). Many radiological parameters of patellar morphology were significantly different between the two groups at the final follow\u2010up, including well\u2010known parameters, such as the mean patellar width (surgery group, 40.58\u2009mm [SD 1.26]; conservative group, 36.41\u2009mm [SD 1.17]; <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05), the mean patellar thickness (surgery group, 11.59\u2009mm [SD 0.74]; conservative group, 9.38\u2009mm [SD 0.56]; <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05) and the mean Wiberg index (surgery group, 0.54 [SD 0.06]; conservative group, 0.72 [SD 0.08]; <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05). There are also little\u2010known parameters, such as the ratio of length of lateral patella to medial patella (surgery group, 1.26 [SD 0.17]; conservative group, 1.69 [SD 0.21]; <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05), which was a measurement of facet asymmetry. However, the Wiberg angle was not significantly different between the two groups (surgery group, 128.63\u00b0 [SD 9.05]; conservative group, 125.47\u00b0 [SD 13.96\u00b0]; <jats:italic>P<\/jats:italic>\u2009&gt;\u20090.05) at the final follow\u2010up.
