Patients\u2019 pre- and postoperative activity can be measured using the University of California Los Angeles (UCLA) activity score, a validated questionnaire.

Inclusion criteria included lateral center-edge angle &lt;25\u00b0, highly active individuals (UCLA score \u22657), and 10-year minimum follow-up. UCLA, modified Harris Hip Score, and Western Ontario and McMaster Universities Osteoarthritis Index scores and descriptive information were obtained.\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      values &lt;.05 were considered significant.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The cohort included 68 hips (86.1% follow-up; 61 patients), with 7 (10.3%) having additional surgery (4 total hip arthroplasty, 3 osteochondroplasty) at a mean 9.8 years (range, 6.0-15.8). Reoperated hips were excluded; the remaining 61 were analyzed. Mean age at PAO was 24.7 years (range, 14.7-44.8) with female predominance (74.1%). Mean follow-up was 12.5 years (range, 10.2-17.1). Of 61 hips, 54 (88.5%) either maintained high activity with a UCLA score \u22657 (n = 43; 70.5%) or had lower activity unrelated to the surgical hip (n = 11; 18.0%). When compared with preoperative values, the mean UCLA score decreased from 8.9 to 8.1 (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .009); the modified Harris Hip Score improved from 64.6 to 88.8 (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .001), with 49 of 61 hips (80.3%) achieving the minimal clinically important difference; and the Western Ontario and McMaster Universities Osteoarthritis Index pain score improved from 68.2 to 89.0 (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .001), with 35 of 51 hips (68.7%) achieving the minimal clinically important difference.

At long-term follow-up (mean, 12.5 years), 54 of 68 (79.4%) hips did not have additional surgery and either remained in the high activity group or had lower activity levels unrelated to the hip. PAO appears to be a durable hip preservation technique at 12.5-year follow-up for highly active patients.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/03635465251334770","type":"journal-article","created":{"date-parts":[[2025,4,25]],"date-time":"2025-04-25T07:15:53Z","timestamp":1745565353000},"page":"1681-1686","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Activity Level Maintenance at 10-Year Minimum Follow-up Among Active Patients Undergoing Periacetabular Osteotomy"],"prefix":"10.1177","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4927-581X","authenticated-orcid":false,"given":"Deniz C.","family":"Ince","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Washington University School of Medicine, Washington University in St Louis, St Louis, Missouri, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cecilia","family":"Pascual-Garrido","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Washington University School of Medicine, Washington University in St Louis, St Louis, Missouri, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kyle P.","family":"O\u2019Connor","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Washington University School of Medicine, Washington University in St Louis, St Louis, Missouri, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katherine L.","family":"Mistretta","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Washington University School of Medicine, Washington University in St Louis, St Louis, Missouri, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeffrey J.","family":"Nepple","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Washington University School of Medicine, Washington University in St Louis, St Louis, Missouri, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Perry L.","family":"Schoenecker","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Washington University School of Medicine, Washington University in St Louis, St Louis, Missouri, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John C.","family":"Clohisy","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Washington University School of Medicine, Washington University in St Louis, St Louis, Missouri, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,4,25]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.90B5.19746"},{"issue":"12","key":"e_1_3_3_3_2","first-page":"1833","article-title":"Validation study of WOMAC: a health status instrument for measuring clinically important patient relevant outcomes to antirheumatic drug therapy in patients with osteoarthritis of the hip or knee","volume":"15","author":"Bellamy N","year":"1988","unstructured":"Bellamy N, Buchanan WW, Goldsmith CH, Campbell J, Stitt LW.
