The exclusion criteria were as follows: LCEA less than 18\u00b0, T\u00f6nnis osteoarthritis grade greater than 1, prior hip surgical procedures, active inflammatory disease, Workers\u2019 Compensation, and concomitant surgery. Patients underwent propensity matching based on age, sex, body mass index, and T\u00f6nnis osteoarthritis grade. Patient\u2010reported outcome measures included the modified Harris Hip Score, as well as calculation of the minimal clinically important difference, patient acceptable symptom state, and maximum outcome improvement satisfaction threshold. Preoperative radiographic predictors included comparison of the Femoro\u2010epiphyseal Acetabular Roof index and ligamentum teres lesions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 28 PAO patients underwent propensity matching to 49 HA patients. The 2 groups were similar in terms of mean age, sex, preoperative body mass index, and LCEA. The PAO group had a longer mean follow\u2010up period (95.8 months vs 81.3 months,\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .001). The mean Femoro\u2010epiphyseal Acetabular Roof index was significantly lower preoperatively in the HA group (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .001). The 2 groups showed similar and significant improvements in the mean modified Harris Hip Score from preoperatively to latest follow\u2010up (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .001). The relative risk of subsequent surgery in the PAO group was 3.49 (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .024), mostly attributed to hardware removal (25%). The revision rate was 3.6% in the PAO group and 8.2% in the HA group (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .65). One patient in the PAO group required revision HA for intra\u2010articular adhesions. Three of the patients requiring revision in the HA group underwent PAO because of persistent pain, and one underwent revision HA alone. Conversion to total hip arthroplasty was required in 1 patient in the HA group and no patients in the PAO group.\n                    <\/jats:p>\n                  <\/jats:sec>\n
