Functional outcome measures included Constant\u2013Murley (CM), American Shoulder and Elbow Surgeons (ASES), Nottingham Clavicle (NC) scores and the Visual Analogue Scale (VAS) for pain. Patient\u2010specific psychological characteristics and personality structure were evaluated using the Tampa Scale of Kinesiophobia (TSK), General Self\u2010Efficacy Short Scale\u20103 (GSE\u20103), Big Five Inventory Scale (BFI), Revised Life Orientation Test (LOT\u2010R) and Pain Catastrophizing Scale (PCS). Psychological readiness to return to sport was assessed with the ACJ\u2010Return to Sport after Injury (ACJ\u2010RSI) scale.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n A total of 142 patients (mean age at surgery: 39.2\u2009\u00b1\u200913.7 years; 93 acute and 49 chronic injuries) with a mean follow\u2010up of 6.0\u2009\u00b1\u20092.2 years were included in the study. Patients had a mean CM of 85.2\u2009\u00b1\u200913.1, ASES of 93.0\u2009\u00b1\u200913.1, NC of 86.0\u2009\u00b1\u200913.8, VAS for pain of 2.0\u2009\u00b1\u20091.4 and ACJ\u2010RSI of 75.0\u2009\u00b1\u200923.7 at final follow\u2010up.

LOT\u2010R for optimism was positively correlated with ASES (\n \u03c1<\/jats:italic>\n \u2009=\u20090.29;\n P<\/jats:italic>\n \u2009=\u20090.001) and NC (\n \u03c1<\/jats:italic>\n \u2009=\u20090.27;\n P<\/jats:italic>\n \u2009=\u20090.003), while LOT\u2010R for pessimism was only negatively correlated with ASES (\n \u03c1<\/jats:italic>\n \u2009=\u2009\u22120.20;\n P<\/jats:italic>\n \u2009=\u20090.043).

Functional outcome scores were positively correlated with the patients' self\u2010efficacy and optimistic outlook on life, while for kinesiophobia, catastrophizing of pain and neuroticism, a negative correlation was observed.<\/jats:p>\n <\/jats:sec>\n \n Level of Evidence<\/jats:title>\n Level IV retrospective study.<\/jats:p>\n <\/jats:sec>","DOI":"10.1002\/ksa.70349","type":"journal-article","created":{"date-parts":[[2026,3,8]],"date-time":"2026-03-08T15:38:22Z","timestamp":1772984302000},"page":"2205-2214","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Patient\u2010specific psychological characteristics and personality structure affect functional outcomes after surgical stabilization of acute and chronic acromioclavicular joint injuries"],"prefix":"10.1002","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7393-1891","authenticated-orcid":false,"given":"Lukas Nawid","family":"Muench","sequence":"first","affiliation":[{"name":"Department of Sports Orthopaedics TUM University Hospital Munich Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ali Can","family":"Gunenc","sequence":"additional","affiliation":[{"name":"Department of Sports Orthopaedics TUM University Hospital Munich Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marco\u2010Christopher","family":"Rupp","sequence":"additional","affiliation":[{"name":"Department of Sports Orthopaedics TUM University Hospital Munich Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lisa","family":"Rahn","sequence":"additional","affiliation":[{"name":"Department of Sports Orthopaedics TUM University Hospital Munich Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frank","family":"Martetschl\u00e4ger","sequence":"additional","affiliation":[{"name":"ATOS Clinic Munich Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Armin","family":"Runer","sequence":"additional","affiliation":[{"name":"Department of Sports Orthopaedics TUM University Hospital Munich Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lucca","family":"Lacheta","sequence":"additional","affiliation":[{"name":"Department of Sports Orthopaedics TUM University Hospital Munich Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebastian","family":"Siebenlist","sequence":"additional","affiliation":[{"name":"Department of Sports Orthopaedics TUM University Hospital Munich Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bastian","family":"Scheiderer","sequence":"additional","affiliation":[{"name":"Department of Sports Orthopaedics TUM University Hospital Munich Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,2,24]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.1177\/23259671241289117"},{"key":"e_1_2_12_3_1","first-page":"251","article-title":"Kurzskala zur erfassung allgemeiner selbstwirksamkeitserwartungen (ASKU)","volume":"7","author":"Beierlein C","year":"2013","journal-title":"Methoden Daten Anal"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2012.11.023"},{"key":"e_1_2_12_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2013.11.005"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.eats.2015.07.029"},{"key":"e_1_2_12_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-020-06123-0"},{"key":"e_1_2_12_8_1","doi-asserted-by":"crossref","unstructured":"Cohen J.
