Four years later, she experienced persistent knee pain. Computed tomography revealed tibial malalignments in 2 planes. In vivo kinematic analysis using single-plane fluoroscopy, which can visualize the femorotibial contact, indicated varus thrust with lateral subluxation of the tibial component and the femoral component recessing into the polyethylene insert. Revision TKA affirmed the polyethylene insert breakage.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Malalignment might have caused mechanical failure, and in vivo kinematic analysis was useful to visualize abnormal kinematics in TKA.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.2106\/jbjs.cc.24.00466","type":"journal-article","created":{"date-parts":[[2025,1,16]],"date-time":"2025-01-16T14:03:19Z","timestamp":1737036199000},"update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Detection of Multiple Tibial Malalignment-Induced Early Polyethylene Breakage Using Single Plane Fluoroscopy"],"prefix":"10.2106","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-4784-5526","authenticated-orcid":false,"given":"Atsushi","family":"Sugimoto","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Osaka University Graduate School of Medicine, Suita, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0835-8467","authenticated-orcid":false,"given":"Teruya","family":"Ishibashi","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Biomaterial Science, Osaka University Graduate School of Medicine, Suita, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takaharu","family":"Yamazaki","sequence":"additional","affiliation":[{"name":"Department of Information Systems, Faculty of Engineering, Saitama Institute of Technology, Saitama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4942-7446","authenticated-orcid":false,"given":"Masashi","family":"Tamaki","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Osaka University Graduate School of Medicine, Suita, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5107-8209","authenticated-orcid":false,"given":"Seiji","family":"Okada","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Osaka University Graduate School of Medicine, Suita, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tetsuya","family":"Tomita","sequence":"additional","affiliation":[{"name":"Morinomiya University of Medical Sciences, Graduate School of Health Sciences, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2025,1]]},"reference":[{"issue":"13","key":"bib1-20250116","doi-asserted-by":"crossref","first-page":"1396","DOI":"10.1055\/s-0041-1735282","article-title":"The epidemiology of revision total knee arthroplasty","volume":"34","author":"Tarazi","year":"2021","journal-title":"J Knee Surg."},{"issue":"1","key":"bib2-20250116","doi-asserted-by":"crossref","first-page":"55","DOI":"10.1186\/s12891-018-1977-y","article-title":"Analysis of total knee arthroplasty revision causes","volume":"19","author":"Postler","year":"2018","journal-title":"BMC Musculoskelet Disord."},{"issue":"9","key":"bib3-20250116","doi-asserted-by":"crossref","first-page":"715","DOI":"10.2106\/JBJS.M.01534","article-title":"Current failure mechanisms after knee arthroplasty have changed: polyethylene wear is less common in revision surgery","volume":"97","author":"Thiele","year":"2015","journal-title":"J Bone Jt Surg Am."},{"key":"bib4-20250116","doi-asserted-by":"crossref","first-page":"60","DOI":"10.1016\/j.jor.2020.12.008","article-title":"Reasons for failure in primary total knee arthroplasty\u2014an analysis of prospectively collected registry data","volume":"23","author":"Mathis","year":"2021","journal-title":"J Orthop."},{"key":"bib5-20250116","doi-asserted-by":"crossref","first-page":"835","DOI":"10.1186\/s40064-015-1604-4","article-title":"Does malalignment affect revision rate in total knee replacements: a systematic review of the literature","volume":"4","author":"Hadi","year":"2015","journal-title":"Springerplus."},{"issue":"2","key":"bib6-20250116","doi-asserted-by":"crossref","first-page":"419","DOI":"10.1007\/s00167-021-06811-5","article-title":"What is the \u201csafe zone\u201d for transition of coronal alignment from systematic to a more personalised one in total knee arthroplasty?
