Dorr's classification of proximal femoral geometry, acetabular protrusio, bone ankylosis, acetabular protrusion, Brooker classification of heterotopic ossification (HO), Gruen and Charnley classifications of implant loosening were used in radiographic assessments. Patients were called back to return for an additional long-term follow-up for functional assessment.\n\nResults: Cementless total hip arthroplasty was used in 83 hips (79%) and cemented TKA was used in 22 hips (21%). The overall rate of aseptic loosening was 7.6% at a mean follow-up of 5.4 years. Femoral loosening was statistically similar in cemented and cementless femoral components (14% vs. 8%, p &amp;frac14; 0.089). Acetabular component loosening was statistically higher in patients with any degree of HO (p &amp;frac14; 0.04). Regardless of the type of femoral implant (cemented or cementless), femoral component loosening was higher in Dorr's type C patients (p &amp;frac14; 0.005). The average pre-operative HSS was 46.6 \u00b1 16.3, and it improved to 80.7 \u00b1 18.7 at last follow-up (p &lt; 0.01).\n\nConclusion: Revision incidence was similar in between ankylosed and non-ankylosed hips. While complication rates are high, significant functional improvement can be achieved after THA in patients with AS.<\/jats:p>","DOI":"10.1016\/j.aott.2016.06.010","type":"journal-article","created":{"date-parts":[[2016,8,3]],"date-time":"2016-08-03T01:01:19Z","timestamp":1470186079000},"page":"443-447","update-policy":"https:\/\/doi.org\/10.1016\/elsevier_cm_policy","source":"Crossref","is-referenced-by-count":36,"title":["Total hip arthroplasty in patients with ankylosing spondylitis: Midterm radiologic and functional results"],"prefix":"10.5152","volume":"50","author":[{"given":"Yavuz","family":"Saglam","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u0130rfan","family":"\u00d6zt\u00fcrk","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mehmet","family":"Fevzi \u00c7akmak","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mustafa","family":"\u00d6zdemir","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00d6nder","family":"Yaz\u0131c\u0131o\u011flu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3111","published-online":{"date-parts":[[2020,2,7]]},"reference":[{"key":"10.1016\/j.aott.2016.06.010_bib1","doi-asserted-by":"crossref","first-page":"73","DOI":"10.1093\/rheumatology\/kep174","article-title":"Hip involvement in ankylosing spondylitis: epidemiology and risk factors associated with hip replacement surgery","volume":"49","author":"Vander Cruyssen","year":"2010","journal-title":"Rheumatology (Oxford)"},{"key":"10.1016\/j.aott.2016.06.010_bib2","doi-asserted-by":"crossref","first-page":"243","DOI":"10.1186\/1471-2474-13-243","article-title":"The information needs of people living with ankylosing spondylitis: a questionnaire survey","volume":"13","author":"Cooksey","year":"2012","journal-title":"BMC Musculoskelet Disord"},{"key":"10.1016\/j.aott.2016.06.010_bib3","doi-asserted-by":"crossref","first-page":"1115","DOI":"10.1007\/s10067-013-2278-3","article-title":"Management of hip involvement in ankylosing spondylitis","volume":"32","author":"Guan","year":"2013","journal-title":"Clin Rheumatol"},{"key":"10.1016\/j.aott.2016.06.010_bib4","doi-asserted-by":"crossref","first-page":"117","DOI":"10.1054\/arth.2001.19160","article-title":"Socket wear in bilateral simultaneous total hip arthroplasty","volume":"16","author":"Joshi","year":"2001","journal-title":"J Arthroplast"},{"key":"10.1016\/j.aott.2016.06.010_bib5","doi-asserted-by":"crossref","first-page":"330","DOI":"10.3944\/AOTT.2013.3103","article-title":"Etiology of coxarthrosis in patients with total hip replacement","volume":"47","author":"Ulucay","year":"2013","journal-title":"Acta Orthop Traumatol Turc"},{"key":"10.1016\/j.aott.2016.06.010_bib6","doi-asserted-by":"crossref","first-page":"1543","DOI":"10.1002\/art.30223","article-title":"Clinical efficacy and safety of etanercept versus sulfasalazine in patients with ankylosing spondylitis: a randomized, double-blind trial","volume":"63","author":"Braun","year":"2011","journal-title":"Arthritis Rheum"},{"key":"10.1016\/j.aott.2016.06.010_bib7","first-page":"CD004524","article-title":"Methotrexate for ankylosing spondylitis","volume":"2","author":"Chen","year":"2013","journal-title":"Cochrane Database Syst Rev"},{"key":"10.1016\/j.aott.2016.06.010_bib8","doi-asserted-by":"crossref","first-page":"859","DOI":"10.1016\/j.arth.2007.07.014","article-title":"Primary cementless total hip arthroplasty for bony ankylosis in patients with ankylosing spondylitis","volume":"23","author":"Bhan","year":"2008","journal-title":"J Arthroplast"},{"key":"10.1016\/j.aott.2016.06.010_bib9","doi-asserted-by":"crossref","first-page":"231","DOI":"10.1016\/8756-3282(93)90146-2","article-title":"Structural and cellular assessment of bone quality of proximal femur","volume":"14","author":"Dorr","year":"1993","journal-title":"Bone"},{"key":"10.1016\/j.aott.2016.06.010_bib10","first-page":"524","article-title":"The aetiology of protrusio acetabuli.
