This study aimed to compare radiological and early clinical outcomes of conventional (cTHA) and robotic (rTHA) THA in patients with Crowe Type 3 and 4 DDH.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Patients who underwent cTHA or rTHA were retrospectively analysed. Preoperative and postoperative clinical parameters, including range of motion (ROM), visual analogue scale (VAS) pain scores, modified Harris Hip Score (mHHS), and leg-length discrepancy, were evaluated. Radiological assessments included implant positioning (acetabular inclination and anteversion, femoral anteversion) using x-ray and CT imaging. Operative durations for cTHA and rTHA were also compared.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>A total of 45 patients (52 hips) were included. Both groups showed significant improvements in clinical and radiological outcomes. Postoperative VAS pain scores were lower in the rTHA group (1.35\u2009\u00b1\u20091.00 vs. 2.41\u2009\u00b1\u20091.14 for cTHA), and mHHS was higher (92.34\u2009\u00b1\u20095.68 vs. 79.68\u2009\u00b1\u20095.92 for cTHA). ROM and radiological parameters, such as acetabular inclination (37.11\u2009\u00b1\u20093.37\u00b0 for rTHA vs. 41.13\u2009\u00b1\u20096.49\u00b0 for cTHA) and anteversion (17.59\u2009\u00b1\u20091.78\u00b0 for rTHA vs. 21.87\u2009\u00b1\u20091.71\u00b0 for cTHA), were more precise in rTHA. Operative time was longer for rTHA (117.06\u2009\u00b1\u20098.16 vs. 79.71\u2009\u00b1\u20096.79\u2009minutes).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Robotic THA achieved better implant positioning and superior early clinical outcomes compared to conventional THA in complex DDH cases, despite longer surgical times.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/11207000251385064","type":"journal-article","created":{"date-parts":[[2025,11,12]],"date-time":"2025-11-12T12:26:27Z","timestamp":1762950387000},"page":"278-286","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Comparison of robotic and conventional total hip arthroplasty in Crowe type 3\u20134 hip dysplasia: a retrospective analysis of radiological precision and early clinical outcomes"],"prefix":"10.1177","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5530-7729","authenticated-orcid":false,"given":"Yusuf","family":"Iyetin","sequence":"first","affiliation":[{"name":"Orthopaedics and Traumatology, Pendik Bolge Hospital, Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2715-2875","authenticated-orcid":false,"given":"Emre","family":"Koraman","sequence":"additional","affiliation":[{"name":"Orthopaedics and Traumatology, Pendik Bolge Hospital, Istanbul, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6822-5703","authenticated-orcid":false,"given":"Mehmet","family":"Akan","sequence":"additional","affiliation":[{"name":"Orthopaedics and Traumatology, Ministry of Health Luleburgaz State Hospital, K\u0131rklareli, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muhlik","family":"Akyurek","sequence":"additional","affiliation":[{"name":"Orthopaedics and Traumatology, Maria-Josef-Hospital Greven, Greven, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,11,12]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00402-020-03749-0"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00264-014-2613-6"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2017.02.024"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1007\/s12178-011-9086-7"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-200003000-00003"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1186\/s42836-019-0004-6"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-014-4103-y"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1002\/rcs.2332"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1002\/rcs.1990"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.100B10-BJJ-2018-0201.R1"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-013-3253-7"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.1002\/rcs.2463"},{"key":"e_1_3_2_14_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00264-021-05015-3"},{"key":"e_1_3_2_15_2","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.15.01080"},{"key":"e_1_3_2_16_2","first-page":"283","article-title":"Robotic-arm assisted surgery in total hip arthroplasty","volume":"26","author":"Elmallah RK","year":"2015","unstructured":"Elmallah RK, Cherian JJ, Jauregui JJ, et al.
