There were 3 failures: 1 LCP due to instability at 2.4\u2009years, 1 SCFE due to femoral neck fracture at 1 month, and another SCFE due to unexplained pain at 5.8\u2009years. Five patients, 1 LCP and 4 SCFE, had retained hardware prior to surgery; 4 had their hardware removed during surgery. Postoperatively HHS and UCLA activity scores increased ( p &lt; 0.0001, for both measures). Leg-length discrepancy improved preoperatively from 7.9 (0.0\u201332) mm to 0.65 (0.0\u201310) mm postoperatively ( p &lt; 0.0001). Follow-up radiographs of all non-failure HRA patients revealed implants to be in good alignment with no indication of loosening.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Although HRA in SCFE and LCP patients increases technical difficulties, findings demonstrate excellent implant survival, no intraoperative complications, and improvements in leg-length discrepancies and clinical functional outcomes.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/1120700019858728","type":"journal-article","created":{"date-parts":[[2019,6,24]],"date-time":"2019-06-24T01:23:05Z","timestamp":1561339385000},"page":"572-580","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Hip resurfacing arthroplasty for end-stage arthritis caused by childhood hip disease"],"prefix":"10.1177","volume":"30","author":[{"given":"Edwin P","family":"Su","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Adult Reconstruction and Joint Replacement Division, Hospital for Special Surgery, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rachelle","family":"Morgenstern","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Adult Reconstruction and Joint Replacement Division, Hospital for Special Surgery, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Imraan","family":"Khan","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Adult Reconstruction and Joint Replacement Division, Hospital for Special Surgery, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melissa D","family":"Gaillard","sequence":"additional","affiliation":[{"name":"Midlands Orthopaedics, Columbia, SC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas P","family":"Gross","sequence":"additional","affiliation":[{"name":"Midlands Orthopaedics, Columbia, SC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2019,6,23]]},"reference":[{"key":"bibr1-1120700019858728","doi-asserted-by":"publisher","DOI":"10.1007\/s12178-016-9324-0"},{"key":"bibr2-1120700019858728","doi-asserted-by":"publisher","DOI":"10.1007\/s00264-010-1053-1"},{"key":"bibr3-1120700019858728","doi-asserted-by":"publisher","DOI":"10.1177\/0363546509357609"},{"key":"bibr4-1120700019858728","doi-asserted-by":"publisher","DOI":"10.1007\/s00264-013-1834-4"},{"key":"bibr5-1120700019858728","unstructured":"Association Orthopaedic Association National Joint Replacement Registry.
