New therapeutic concepts suggest that early one-stage treatment, including suturing and bracing of the cruciate ligaments in acute knee joint dislocation, are leading to improved functional results. This study aimed to evaluate the midterm functional outcome following traumatic knee joint dislocation and to determine whether the outcome is influenced by the surgical management, patient habitus or concomitant injuries. Methods: In this retrospective single center study, 38 patients with acute Schenck type II to IV knee dislocations were treated over an eight-year period in a level I trauma center. At follow-up, various clinical scores, such as the International Knee Documentation Committee (IKDC) Score, Lysholm Score, and Tegner Activity Scale (TAS), and individual questions about rehabilitation and activity levels of 38 patients were evaluated. Results: Mean follow-up was 5.5 \u00b1 2.7 years. The mean IKDC Score was 65.6 \u00b1 15.7 points, the average Lysholm Score was 70.5 \u00b1 16.4 points and the median TAS was 4 (0\u20137), resulting in a loss of activity of 2 (range 0\u20136) points. There was no significant difference between a one-stage treatment compared to a two-stage approach. Ligament reconstruction of the ACL in a two-stage approach was required in only 33.3%. Further operations (early and late) were performed in 37% of cases. Being overweight was associated with more complications and worse outcomes, and external fixation with arthrofibrosis. Conclusions: Knee dislocation is a severe trauma that often leads to a prolonged loss of function and increased knee pain over years, affecting the patient\u2019s activity. Clinical outcome is influenced significantly by concomitant injuries. Severe cases with initial external fixation are associated with a higher risk of knee stiffness and should be considered during rehabilitation. Obese patients present a challenge due to higher complication rates and lower postoperative knee function. Level of evidence: Retrospective single center study, level III.<\/jats:p>","DOI":"10.3390\/jcm12010266","type":"journal-article","created":{"date-parts":[[2022,12,30]],"date-time":"2022-12-30T03:18:18Z","timestamp":1672370298000},"page":"266","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Mid-Term Results following Traumatic Knee Joint Dislocation"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0578-4142","authenticated-orcid":false,"given":"Julius","family":"Watrinet","sequence":"first","affiliation":[{"name":"Department Trauma Surgery, BG Unfallklinik Murnau, 82418 Murnau, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6308-8378","authenticated-orcid":false,"given":"Christian","family":"von R\u00fcden","sequence":"additional","affiliation":[{"name":"Department Trauma Surgery, BG Unfallklinik Murnau, 82418 Murnau, Germany"},{"name":"Institute for Biomechanics, Paracelsus Medical University, 5020 Salzburg, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephan","family":"Regenbogen","sequence":"additional","affiliation":[{"name":"Department Trauma Surgery, BG Unfallklinik Murnau, 82418 Murnau, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5776-2175","authenticated-orcid":false,"given":"Andreas","family":"Brand","sequence":"additional","affiliation":[{"name":"Institute for Biomechanics, Paracelsus Medical University, 5020 Salzburg, Austria"},{"name":"Institute of Biomechanics, BG Trauma Center Murnau, 82418 Murnau, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7024-3620","authenticated-orcid":false,"given":"Markus","family":"Bormann","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Trauma Surgery, Musculoskeletal University Center Munich (MUM), University Hospital, LMU Munich, 81377 Munich, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fabian M.","family":"Stuby","sequence":"additional","affiliation":[{"name":"Department Trauma Surgery, BG Unfallklinik Murnau, 82418 Murnau, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5529-1632","authenticated-orcid":false,"given":"Julian","family":"F\u00fcrmetz","sequence":"additional","affiliation":[{"name":"Department Trauma Surgery, BG Unfallklinik Murnau, 82418 Murnau, Germany"},{"name":"Department of Orthopaedics and Trauma Surgery, Musculoskeletal University Center Munich (MUM), University Hospital, LMU Munich, 81377 Munich, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"192","DOI":"10.1097\/00005373-196903000-00002","article-title":"Complete dislocation of the knee: Experience at the Massachusetts General Hospital","volume":"9","author":"Shields","year":"1969","journal-title":"J.
