The exclusion criteria included patients undergoing bilateral or revision surgery, those with a history of dysplasia, and those with less than 2\u00a0years' follow\u2010up. On radiographs, the SIJs were graded using modified New York criteria for spondyloarthropathy. CT and MRI scans were reviewed for joint surface erosion, subchondral sclerosis, joint space narrowing, pseudo\u2010widening, bone marrow edema, and ankylosis. Patients with SIJ abnormalities were matched to patients without SIJ abnormalities in a 1:2 ratio by age and body mass index. Outcomes included the Hip Outcome Score\u2013Activities of Daily Living (HOS\u2010ADL), Hip Outcome Score\u2013Sports Subscale (HOS\u2010SS), modified Harris Hip Score (mHHS), visual analog scale (VAS) for pain, and VAS for satisfaction.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Of 1,009 consecutive patients, 743 (73.6%) were included; 187 (25.2%) showed SIJ changes. Of these 187 patients, 164 (87.7%) had changes on plain radiographs, 88 (47.1%) had changes on CT, and 125 (66.8%) had changes on MRI. SIJ changes on any imaging modality were weakly correlated with pain to palpation of the SIJ (\n                      <jats:italic>r<\/jats:italic>\n                      \u00a0= 0.11,\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0=\u00a0.004) on physical examination.
