The objective of this study was to identify the frequency of PJIs in cases of UKA with progressed secondary osteoarthritis and the result of septic one-stage revision in these cases to verify the value of preoperative aspiration in cases of secondary osteoarthritis of UKA. Methods: We retrospectively reviewed 97 patients with a unicompartmental arthroplasty who underwent revision surgery to a total knee arthroplasty (TKA) between January 2013 and March 2021 because of subsequent osteoarthritis. Preoperative aspiration and sample collection during the revision surgery were employed to identify potential periprosthetic joint infections (PJIs). The post-revision period was monitored for septic complications over an average duration of 55.7 \u00b1 25.2 months (24\u2013113). Results: PJIs were identified in 5.2% of cases through preoperative aspiration. In all instances of PJIs, a one-stage septic revision was performed, and notably, none of these cases experienced septic complications during the follow-up period. Conclusions: Preoperative aspiration is essential in order to exclude the presence of a PJI before performing revision surgery of UKA due to secondary osteoarthritis.<\/jats:p>","DOI":"10.3390\/antibiotics13040361","type":"journal-article","created":{"date-parts":[[2024,4,15]],"date-time":"2024-04-15T10:24:26Z","timestamp":1713176666000},"page":"361","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["How Useful Is Preoperative Aspiration before Revision of Unicompartmental Knee Prostheses Because of Osteoarthritis in the Other Compartments?"],"prefix":"10.3390","volume":"13","author":[{"given":"Benedikt Paul","family":"Blersch","sequence":"first","affiliation":[{"name":"Department of Joint Replacement, General and Rheumatic Orthopaedics, Orthopaedic Clinic Markgr\u00f6ningen gGmbH, Kurt-Lindemann-Weg 10, 71706 Markgr\u00f6ningen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Florian Hubert","family":"Sax","sequence":"additional","affiliation":[{"name":"Department of Joint Replacement, General and Rheumatic Orthopaedics, Orthopaedic Clinic Markgr\u00f6ningen gGmbH, Kurt-Lindemann-Weg 10, 71706 Markgr\u00f6ningen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7485-3941","authenticated-orcid":false,"given":"Bernd","family":"Fink","sequence":"additional","affiliation":[{"name":"Department of Joint Replacement, General and Rheumatic Orthopaedics, Orthopaedic Clinic Markgr\u00f6ningen gGmbH, Kurt-Lindemann-Weg 10, 71706 Markgr\u00f6ningen, Germany"},{"name":"Orthopaedic Department, University Hospital Hamburg-Eppendorf, Martinistrasse 52, 20246 Hamburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"102","DOI":"10.1007\/s11999-012-2517-y","article-title":"Long-term survivorship and failure modes of unicompartmental 170 knee arthroplasty","volume":"471","author":"Foran","year":"2013","journal-title":"Clin.
