The ARO was evaluated both on the acetabular gross anatomy (AGA) and coronal sections of CT, for its position, width (unit: mm), area (unit: mm\n                      <jats:sup>2<\/jats:sup>\n                      ), and CT value (unit: HU). Patients were divided into 4 groups based on the extent of ARO on coronal CT: group A (ARO anterior to 12 o\u2019clock), group P (ARO posterior to 12 o\u2019clock), group AP (ARO across 12 o\u2019clock), and group N (no ARO). Inter\u2010 and intraobserver correlation was analyzed. Demographic data, FAI deformity indicators on imaging, quantitative measurements of ARO, and pre\u2010 and postoperative patient\u2010reported outcomes were compared among groups.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      There were 229 patients (229 hips) enrolled in total, 122 male (53.3%) and 107 female (46.7%), with a mean age of 37.2 \u00b1 10.2 years. The correlation between 2 observers for grouping ARO using AGA was positive but poor (Kendall Tau\u2010b coefficient\u00a0= 0.157,\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .008).
