The overall incidence of femoral and tibial RLL was 24% and 26%, respectively. Of the original cohort, two patients had to be revised during the course of the study, resulting in a survival rate of 98.9% at two years with the endpoint \u201crevision for any reason\u201d.

However, a high incidence of periprosthetic RLL was seen in this cohort. No implant showed signs of component loosening, but patients with RLL should be monitored closely and future studies with longer follow-up durations are necessary to investigate the influence of these radiolucencies on the long-term performance of this knee system.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s00402-025-05824-w","type":"journal-article","created":{"date-parts":[[2025,3,21]],"date-time":"2025-03-21T02:48:42Z","timestamp":1742525322000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["The incidence of radiolucent lines in cemented attune total knee arthroplasty\u2013 a retrospective clinical and radiological study"],"prefix":"10.1007","volume":"145","author":[{"given":"Reza","family":"Sorbi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tilman","family":"Walker","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Timo A.","family":"Nees","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tobias","family":"Renkawitz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Babak","family":"Moradi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4563-6718","authenticated-orcid":false,"given":"Tobias","family":"Reiner","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2025,3,20]]},"reference":[{"key":"5824_CR1","first-page":"248","volume-title":"Revision after early aseptic failures in primary total knee arthroplasty","author":"SR Piedade","year":"2009","unstructured":"Piedade SR, Pinaroli A, Servien E, Neyret P (2009) Revision after early aseptic failures in primary total knee arthroplasty, vol 17.
