The aim of this study was to evaluate the clinical outcomes of a modified interpositional arthroplasty technique using an iliotibial band autograft fixed to the proximal phalanx in patients with advanced hallux rigidus. Materials and Methods: This prospective observational case series included 19 patients with Coughlin\u2013Shurnas Grade III or IV hallux rigidus who underwent surgery between February 2023 and February 2025. Clinical outcomes were assessed using Visual Analog Scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS), and range-of-motion (ROM) measurements preoperatively and at postoperative 1, 6, and 12 months. Results: The mean VAS score decreased from 9.0 \u00b1 0.82 preoperatively to 1.58 \u00b1 0.51 at 12 months (p &lt; 0.001). The mean AOFAS score increased from 35.1 \u00b1 2.7 to 74.8 \u00b1 10.9 (p = 0.001). ROM improved significantly at 1 and 6 months; however, the 12-month ROM was not significantly different from the preoperative value (36.3\u00b0 \u00b1 5.6\u00b0 vs. 31.0\u00b0 \u00b1 5.5\u00b0, p = 0.082). Conclusions: Interpositional arthroplasty using an iliotibial band autograft fixed to the proximal phalanx was associated with short-term reductions in pain and improvements in functional scores. However, the early increase in range of motion was not maintained to the same extent at 12 months.<\/jats:p>","DOI":"10.3390\/medicina62081537","type":"journal-article","created":{"date-parts":[[2026,8,10]],"date-time":"2026-08-10T15:10:24Z","timestamp":1786374624000},"page":"1537","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Interpositional Arthroplasty with Iliotibial Band Autograft Fixation to the Proximal Phalanx: Clinical Outcomes in Advanced Hallux Rigidus"],"prefix":"10.3390","volume":"62","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3513-8240","authenticated-orcid":false,"given":"Furkan","family":"Soy","sequence":"first","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Faculty of Medicine, K\u0131r\u0131kkale University, K\u0131r\u0131kkale 71450, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5433-0481","authenticated-orcid":false,"given":"Yasin","family":"Kozan","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Akda\u011fmadeni State Hospital, Yozgat 66300, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2292-922X","authenticated-orcid":false,"given":"Ozan","family":"Pehlivan","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Faculty of Medicine, K\u0131r\u0131kkale University, K\u0131r\u0131kkale 71450, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2696-8303","authenticated-orcid":false,"given":"Sancar","family":"Serbest","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Faculty of Medicine, K\u0131r\u0131kkale University, K\u0131r\u0131kkale 71450, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,10]]},"reference":[{"key":"ref_1","first-page":"e2022218","article-title":"Hallux rigidus: Current concepts review and treatment algorithm with special focus on interposition arthroplasty","volume":"93","author":"Mosca","year":"2022","journal-title":"Acta Biomed."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"2473011418814427","DOI":"10.1177\/2473011418814427","article-title":"Outcomes Following Interposition Arthroplasty of the First Metatarsophalangeal Joint for the Treatment of Hallux Rigidus: A Systematic Review","volume":"4","author":"Emmons","year":"2019","journal-title":"Foot Ankle Orthop."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"145","DOI":"10.1007\/s00264-007-0457-z","article-title":"Resection arthroplasty with and without capsular interposition for treatment of severe hallux rigidus","volume":"33","author":"Schenk","year":"2009","journal-title":"Int.
