The indication for a fusion of the joint is based on the pain and disability of the patient, radiographic imaging, and surgeon experience, with no strict guidelines. We aimed to compare outcomes after tibiotalocalcaneal arthrodesis (TTCA) and tibiotalar arthrodesis (TTA) to highlight the functional importance of the subtalar joint. In total, 432 patients with ankle arthrodesis were retrospectively enrolled. Group A (n = 216) underwent TTCA; group B (n = 216) underwent TTA. Demographics, Olerud &amp; Molander Ankle Score (OMAS), Foot Function Index (FFI-D), and Short Form-12 Questionnaire (SF-12) were recorded at a mean follow-up of 6.2 years. The mean OMAS was 50.7; the mean FFI-D was 68.9; the mean SF-12 physical component summary was 39.1. These scores differed significantly between the groups (p &lt; 0.001). The overall revision rate was 18%, primarily for revision of non-union and infection (p &lt; 0.001). Approximately 16% of group A and 26% of group B were able to return to previous work (p &lt; 0.001). Based on significantly worse clinical scores of TTCA compared to TTA and the prolonged downtime and permanent incapacity, the indication for a generous subtalar joint arthrodesis with planned ankle arthrodesis should always be critically examined.<\/jats:p>","DOI":"10.3390\/jcm12093123","type":"journal-article","created":{"date-parts":[[2023,4,26]],"date-time":"2023-04-26T01:44:42Z","timestamp":1682473482000},"page":"3123","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Preservation of the Subtalar Joint Determines Outcomes in a 10-Year Evaluation of Ankle Arthrodesis"],"prefix":"10.3390","volume":"12","author":[{"given":"Rebecca","family":"Sell","sequence":"first","affiliation":[{"name":"Department of Foot and Ankle Surgery, Berufsgenossenschaftliche Unfallklinik Frankfurt am Main, 60389 Frankfurt am Main, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Magalie","family":"Meinert","sequence":"additional","affiliation":[{"name":"Department for Trauma and Orthopaedic Surgery, Berufsgenossenschaftliche Unfallklinik Frankfurt am Main, 60389 Frankfurt am Main, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0662-6675","authenticated-orcid":false,"given":"Eva","family":"Herrmann","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Biostatistik und Mathematische Modellierung, Goethe-Universit\u00e4t Frankfurt am Main, Theodor-Stern-Kai 7, 60596 Frankfurt am Main, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yves","family":"Gramlich","sequence":"additional","affiliation":[{"name":"Department for Trauma and Orthopaedic Surgery, Berufsgenossenschaftliche Unfallklinik Frankfurt am Main, 60389 Frankfurt am Main, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander","family":"Klug","sequence":"additional","affiliation":[{"name":"Department for Trauma and Orthopaedic Surgery, Berufsgenossenschaftliche Unfallklinik Frankfurt am Main, 60389 Frankfurt am Main, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oliver","family":"Neun","sequence":"additional","affiliation":[{"name":"Department of Foot and Ankle Surgery, Berufsgenossenschaftliche Unfallklinik Frankfurt am Main, 60389 Frankfurt am Main, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Reinhard","family":"Hoffmann","sequence":"additional","affiliation":[{"name":"Department for Trauma and Orthopaedic Surgery, Berufsgenossenschaftliche Unfallklinik Frankfurt am Main, 60389 Frankfurt am Main, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9842-2249","authenticated-orcid":false,"given":"Sebastian","family":"Fischer","sequence":"additional","affiliation":[{"name":"Department of Foot and Ankle Surgery, Berufsgenossenschaftliche Unfallklinik Frankfurt am Main, 60389 Frankfurt am Main, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,25]]},"reference":[{"key":"ref_1","first-page":"44","article-title":"Epidemiology of ankle arthritis: Report of a consecutive series of 639 patients from a tertiary orthopaedic center","volume":"25","author":"Saltzman","year":"2005","journal-title":"Iowa Orthop.
