The aim of our study was to analyze the clinical function, radiographic outcomes, patient satisfaction, and complications between patients under 50\u2009years old and those over 65\u2009years old who underwent TAA with the INBONE II prosthesis for end\u2010stage ankle arthritis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Patients who received TAA with the INBONE II prosthesis between September 2016 and August 2021 were included in the study. A total of 68 patients were enrolled and divided into two groups based on age: the younger group (28 patients age\u2009\u2264\u200950\u2009years) and the elderly group (40 patients age\u2009\u2265\u200965\u2009years). Demographic data and patient\u2010reported outcomes, including 36\u2010Item Short\u2010Form Health Survey (SF\u201036), American Orthopedic Foot &amp; Ankle Society (AOFAS), Foot Function Index (FFI), and Visual Analogue Scale (VAS) scores, were collected preoperatively and at the latest follow\u2010up. Radiographic measurements, including tibial articular surface angle (TAS), talar tilt angle (TT), and tibial lateral surface angle (TLS), were evaluated on weight\u2010bearing images preoperatively and at the latest follow\u2010up. Range of motion (ROM) and complications were documented. Patient satisfaction was assessed using a five\u2010point Likert scale.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>With a median follow\u2010up of 4\u2009years, there were no statistically significant differences in AOFAS and SF\u201036 scores between the two groups at the latest follow\u2010up. However, the elderly group showed slightly lower VAS and FFI scores compared to the younger group, while the younger group demonstrated slightly greater dorsiflexion angles. There were no statistically significant differences in radiographic evaluations, patient satisfaction, and complications between the two groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The 4\u2010year postoperative outcomes of TAA using the INBONE II prosthesis were comparable between patients younger than 50\u2009years and those older than 65\u2009years, indicating that age alone may not serve as a definitive criterion for patient selection in TAA with this implant.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Trial Registration<\/jats:title>\n                    <jats:p>Retrospectively registered.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence<\/jats:title>\n                    <jats:p>4.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/os.70326","type":"journal-article","created":{"date-parts":[[2026,5,16]],"date-time":"2026-05-16T01:49:53Z","timestamp":1778896193000},"page":"1233-1240","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Comparison of Clinical Outcomes of\n                    <scp>INBONE II<\/scp>\n                    Total Ankle Arthroplasty in Patients Under 50 and Over 65\u2009Years: A 4\u2010Year Retrospective Study"],"prefix":"10.1111","volume":"18","author":[{"given":"Xiangyu","family":"Xu","sequence":"first","affiliation":[{"name":"Department of Foot and Ankle Surgery Beijing Jishuitan Hospital, Capital Medical University  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4845-0348","authenticated-orcid":false,"given":"Baozhou","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Foot and Ankle Surgery Beijing Jishuitan Hospital, Peking University Fourth School of Clinical Medicine  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-7225-3009","authenticated-orcid":false,"given":"Xuewen","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Foot and Ankle Surgery Beijing Jishuitan Hospital, Capital Medical University  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Foot and Ankle Surgery Beijing Jishuitan Hospital, Capital Medical University  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2048-6194","authenticated-orcid":false,"given":"Hui","family":"Du","sequence":"additional","affiliation":[{"name":"Department of Foot and Ankle Surgery Beijing Jishuitan Hospital, Capital Medical University  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaofeng","family":"Gong","sequence":"additional","affiliation":[{"name":"Department of Foot and Ankle Surgery Beijing Jishuitan Hospital, Capital Medical University  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,5,15]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"publisher","DOI":"10.1177\/1071100713511606"},{"key":"e_1_2_13_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10067-014-2703-2"},{"key":"e_1_2_13_4_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 C.
