Despite its benefits, some patients experience CDA failure due to prosthesis-related complications, heterotopic ossification, segmental kyphosis, ASD, or facet joint degeneration, necessitating revision surgery. Reoperation strategies depend on the failure mechanism, instability, sagittal malalignment, and neural compression. Anterior revision is suited for prosthesis failure, recurrent disc herniation, or ASD, enabling prosthesis removal, decompression, and fusion. In select cases, reimplantation may restore motion. Posterior approaches are preferred for facet degeneration, multilevel stenosis, or posterior hypertrophy, with options including foraminotomy, laminoplasty, or laminectomy and fusion. Complex cases may require combined anterior and posterior surgery for optimal decompression and stability. This narrative review outlines revision strategies, emphasizing biomechanical assessment, radiographic evaluation, and patient-specific considerations. Despite surgical challenges, meticulous planning and execution can optimize outcomes.<\/jats:p>","DOI":"10.3390\/jcm14062038","type":"journal-article","created":{"date-parts":[[2025,3,17]],"date-time":"2025-03-17T07:49:57Z","timestamp":1742197797000},"page":"2038","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Reoperation Strategy for Failure of Cervical Disc Arthroplasty at Index and Adjacent Levels"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4237-4556","authenticated-orcid":false,"given":"Chae-Gwan","family":"Kong","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Uijeongbu St. Mary\u2019s Hospital, The Catholic University of Korea College of Medicine, Uijeongbu 11765, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8273-3731","authenticated-orcid":false,"given":"Jong-Beom","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Uijeongbu St. Mary\u2019s Hospital, The Catholic University of Korea College of Medicine, Uijeongbu 11765, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"73","DOI":"10.1016\/j.nec.2019.08.009","article-title":"Cervical disc replacement","volume":"31","author":"Steinberger","year":"2020","journal-title":"Neurosurg.
