One such TWA, the Motec, has demonstrated good results with acceptable complication rates. It has recently been suggested that the metal-on-carbon fibre reinforced poly ether ether ketone (Mo-CFR-PEEK) version of the Motec TWA be implanted instead of the metal-on-metal version. An explant analysis was undertaken on seven Motec Mo-CFR-PEEK TWAs, revised for a variety of reasons, after a mean time of 2 years in vivo. Compared to a new Motec implant, five of the explanted metal heads and three of the CFR-PEEK cups became smoother in vivo, suggesting self-polishing and negative skewness, indicating some material loss in vivo. Two explanted cups showed indentation marks on their rims and one of these was from component impingement with embedded metallic debris. In the short-term, the articulating surfaces of Motec Mo-CFR-PEEK TWAs did not show major damage.<\/jats:p>\n                  <jats:p>Level of evidence: IV<\/jats:p>","DOI":"10.1177\/17531934241249919","type":"journal-article","created":{"date-parts":[[2024,5,23]],"date-time":"2024-05-23T07:21:27Z","timestamp":1716448887000},"page":"114-119","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["Investigation of the short-term in vivo performance of metal-on-carbon fibre reinforced poly ether ether ketone Motec wrists: an explant analysis"],"prefix":"10.1177","volume":"50","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8497-5790","authenticated-orcid":false,"given":"Thomas J.","family":"Joyce","sequence":"first","affiliation":[{"name":"School of Engineering, Newcastle University, Newcastle upon Tyne, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G\u00f6ksu","family":"Kandemir","sequence":"additional","affiliation":[{"name":"School of Engineering, Newcastle University, Newcastle upon Tyne, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Warwick","sequence":"additional","affiliation":[{"name":"Orthopaedics, University Hospital, Southampton, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel J.","family":"Brown","sequence":"additional","affiliation":[{"name":"Faculty of Health and Life Science, University of Liverpool, Liverpool, UK"},{"name":"Liverpool University Hospitals NHS FT, Liverpool, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,5,23]]},"reference":[{"key":"bibr1-17531934241249919","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmbbm.2023.105974"},{"key":"bibr2-17531934241249919","doi-asserted-by":"publisher","DOI":"10.1055\/s-0038-1646956"},{"key":"bibr3-17531934241249919","doi-asserted-by":"publisher","DOI":"10.1142\/S2424835518500388"},{"key":"bibr4-17531934241249919","doi-asserted-by":"publisher","DOI":"10.1177\/1120700020918157"},{"key":"bibr5-17531934241249919","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.104B10.BJJ-2022-0201.R2"},{"key":"bibr6-17531934241249919","unstructured":"International Standards Organisation.
