To date, the risk factors affecting survival are unknown. This study aimed to evaluate the effects of existing implants, positive synovial microbiological culture results, and the American Society of Anesthesiology Physical Status (ASA) classification on the short- and mid-term survival of older patients with primary septic gonarthritis. This retrospective study included 133 older adults &gt;60 years who underwent surgery for primary septic gonarthritis. Data were collected from medical records and public obituaries. Kaplan\u2013Meier survival curves were used to estimate the probability of survival, as well as log-rank tests to measure and compare survival rates over one- and five-year periods. The mean age was 74.9 years (SD \u00b1 9.2), and the 5-year follow-up rate was 74.3% (the mean follow-up was 3000.5 days; SD \u00b1 1771.6). Mean survival was significantly different in patients with implants and without implants (p = 0.015), and between ASA II, ASA III, and ASA IV (p &lt; 0.001). There was no significant difference in the survival of patients with or without a positive synovial microbiological culture (p = 0.08). Older adults with septic monoarthritis and pre-existing medical implants showed impaired survival. The ASA classification prior to surgery for primary septic monoarthritis can be helpful in identifying patients with poorer mid-term outcomes.<\/jats:p>","DOI":"10.3390\/jcm11030755","type":"journal-article","created":{"date-parts":[[2022,1,31]],"date-time":"2022-01-31T01:46:08Z","timestamp":1643593568000},"page":"755","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Short- and Mid-Term Survival of Geriatric Patients with Septic Arthritis of the Knee and the Impact of Risk Factors on Survival"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8598-1295","authenticated-orcid":false,"given":"Nina Pauline","family":"Haag","sequence":"first","affiliation":[{"name":"Department of Orthopedics and Traumatology, Paracelsus Medical University, 90471 Nuremberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3863-1580","authenticated-orcid":false,"given":"Markus","family":"Ge\u00dflein","sequence":"additional","affiliation":[{"name":"Department of Orthopedics and Traumatology, Paracelsus Medical University, 90471 Nuremberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8856-6441","authenticated-orcid":false,"given":"Michael","family":"Millrose","sequence":"additional","affiliation":[{"name":"Department of Orthopedics and Traumatology, Paracelsus Medical University, 90471 Nuremberg, Germany"},{"name":"Department of Trauma Surgery and Sports Medicine, Garmisch-Partenkirchen Medical Centre, 82467 Garmisch-Partenkirchen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Renate","family":"Ziegler","sequence":"additional","affiliation":[{"name":"Institute of Clinical Hygiene, Medical Microbiology and Infectiology, Paracelsus Medical University, 90471 Nuremberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1267-200X","authenticated-orcid":false,"given":"Maximilian","family":"Willauschus","sequence":"additional","affiliation":[{"name":"Department of Orthopedics and Traumatology, Paracelsus Medical University, 90471 Nuremberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J\u00f6rg","family":"Steinmann","sequence":"additional","affiliation":[{"name":"Institute of Clinical Hygiene, Medical Microbiology and Infectiology, Paracelsus Medical University, 90471 Nuremberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hermann Josef","family":"Bail","sequence":"additional","affiliation":[{"name":"Department of Orthopedics and Traumatology, Paracelsus Medical University, 90471 Nuremberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7010-8450","authenticated-orcid":false,"given":"Johannes","family":"R\u00fcther","sequence":"additional","affiliation":[{"name":"Department of Orthopedics and Traumatology, Paracelsus Medical University, 90471 Nuremberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"331","DOI":"10.5811\/westjem.2018.10.40974","article-title":"Evaluation and Management of Septic Arthritis and its Mimics in the Emergency Department","volume":"20","author":"Long","year":"2019","journal-title":"West.
