Computed tomography scans on the surgical hip and ipsilateral distal femur were routinely performed for all participants. Femoral version (FV) and acetabular version (AV) were assessed using axial computed tomography images. The combined rotational morphology was defined as the combination of FV and AV. Preoperative and minimum 2\u2010year postoperative patient\u2010reported outcome scores including visual analog scale, modified Harris Hip Score (mHHS), and the 12\u2010item International Hip Outcome Tool were compared among FAIS patients with normal, increased, and decreased FV\u2010AV combinations. The percentage of patients achieving the minimal clinically important difference (MCID) and patient\u2010acceptable symptom state for the mHHS and 12\u2010item International Hip Outcome Tool was also recorded and compared across the different FV\u2010AV combination groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 205 eligible FAIS patients were analyzed, who were further categorized into normal FV\u2010AV combinations (n\u2009=\u200998), increased FV\u2010AV combinations (n\u2009=\u200962), and decreased FV\u2010AV combinations (n\u2009=\u200945). Statistically significant improvements were found in all patient\u2010reported outcome scores involved when comparing the follow\u2010up results with the preoperative baseline scores (all\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u2009.001).

Although patients with high baseline scores (preoperative mHHS\u2009&gt;\u200990 points) were excluded to control the potential ceiling effect, multivariate regression analysis still found that the decreased FV\u2010AV combination was significantly associated with the failure of patients achieving MCID for mHHS, with an odds ratio of 6.38 (95% confidence interval\u2009=\u20091.30\u201031.36;\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u2009.023).
