The goal of this study is to compare operative techniques to reduce re-dislocation and re-revision in revision hip arthroplasty due to recurrent dislocations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>A retrospective study of revision hip arthroplasties done due to recurrent dislocation prior to 01 January 2014. Electronic physician and provincial health records were used to collect patients\u2019 initial and follow-up data. Treatment failure was defined as either aseptic re-revision or re-dislocation without revision. Time to event was considered as the re-revision date or the date of second dislocation when the latter endpoint was used.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Of 379 operations, 88 (23.2%) had aseptic repeat revision or recurrent dislocation. Of these: 66 (75.0%) due to dislocation with re-revision; 10 (11.4%) due to dislocation with no re-revision surgery; 5 (5.7%) due to aseptic loosening of components; 3 (3.4%) due to osteolysis; 3 (3.4%) due to pseudotumour; and 1 (1.1%) due to periprosthetic fracture. The following factors increase risk of failure: the use of augmented-liners (lipped, oblique and high-offset liners; HR = 1.68, 95% CI, 1.05\u20132.69), periprosthetic femur fracture (HR = 2.80, 95% CI, 1.39\u20138.21) and pelvic discontinuity (HR = 3.69, 95% CI, 1.66\u20138.21). Femur head sizes 36\u201340 mm are protective (HR = 0.54, 95% CI, 0.31\u20130.86). In abductor dysfunction the use of focal constrained liners decreases the risk of failure (HR = 0.13, 95% CI, 0.018\u20130.973).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Larger head sizes and focal constrained liners (abductors dysfunction) should be used and fully constrained liners and augmented-liners should be avoided in a revision hip arthroplasty due to recurrent dislocations.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/1120700019831628","type":"journal-article","created":{"date-parts":[[2019,3,19]],"date-time":"2019-03-19T06:41:33Z","timestamp":1552977693000},"page":"93-100","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":14,"title":["Multivariate analysis of risk factors for re-dislocation after revision for dislocation after total hip arthroplasty"],"prefix":"10.1177","volume":"30","author":[{"given":"Amir","family":"Herman","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Assuta Ashdod Medical Centre, Ashdod, Israel"},{"name":"Ben-Guriun University Faculty of Medicine, Be\u2019er-Sheva, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bassam A","family":"Masri","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, University of British Columbia, Vancouver, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Clive P","family":"Duncan","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, University of British Columbia, Vancouver, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nelson V","family":"Greidanus","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, University of British Columbia, Vancouver, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donald S","family":"Garbuz","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, University of British Columbia, Vancouver, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2019,3,19]]},"reference":[{"key":"bibr1-1120700019831628","doi-asserted-by":"publisher","DOI":"10.1308\/003588408X318156"},{"key":"bibr2-1120700019831628","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-200210000-00008"},{"key":"bibr3-1120700019831628","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-011-2146-x"},{"key":"bibr4-1120700019831628","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2015.08.011"},{"key":"bibr5-1120700019831628","doi-asserted-by":"publisher","DOI":"10.5301\/HIP.2011.8647"},{"key":"bibr6-1120700019831628","doi-asserted-by":"publisher","DOI":"10.1007\/s00402-012-1508-5"},{"key":"bibr7-1120700019831628","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2011.09.010"},{"key":"bibr8-1120700019831628","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-200110000-00011"},{"key":"bibr9-1120700019831628","doi-asserted-by":"crossref","first-page":"115","DOI":"10.3928\/01477447-20090201-23","volume":"32","author":"Yang C","year":"2009","journal-title":"Orthopedics"},{"key":"bibr10-1120700019831628","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2005.05.005"},{"key":"bibr11-1120700019831628","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2005.06.001"},{"key":"bibr12-1120700019831628","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2004.12.054"},{"key":"bibr13-1120700019831628","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2016.02.021"},{"key":"bibr14-1120700019831628","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-013-2858-1"},{"key":"bibr15-1120700019831628","doi-asserted-by":"publisher","DOI":"10.1155\/2013\/629201"},{"key":"bibr16-1120700019831628","doi-asserted-by":"publisher","DOI":"10.1007\/s00264-015-3082-2"},{"key":"bibr17-1120700019831628","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-012-2428-y"},{"key":"bibr18-1120700019831628","doi-asserted-by":"publisher","DOI":"10.3109\/17453674.2012.742395"},{"key":"bibr19-1120700019831628","doi-asserted-by":"publisher","DOI":"10.1016\/j.otsr.2010.08.003"},{"key":"bibr20-1120700019831628","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2015.02.001"},{"key":"bibr21-1120700019831628","doi-asserted-by":"publisher","DOI":"10.1007\/s00264-016-3127-1"},{"key":"bibr22-1120700019831628","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2011.03.021"},{"key":"bibr23-1120700019831628","unstructured":"R Core Team.
