Die klinischen Ergebnisse wurden mit der visuellen Analogskala (VAS), der Tegner-Aktivit\u00e4tsskala (TAS), dem Kujala-Score, dem Knee Injury and Osteoarthritis Outcome Score (KOOS) und dem International Knee Documentation Committee (IKDC) erhoben. Von insgesamt 20\u00a0Patienten konnten 19 (10\u00a0m\u00e4nnlich, 11\u00a0rechtsseitig, 95\u202f% Follow-up-Rate) f\u00fcr die Nachuntersuchung erreicht werden. Der durchschnittliche Follow-up-Zeitraum betrug 62,5\u202f\u00b1\u200920,5 Monate. Die klinischen Outcome-Scores resultierten in folgenden Ergebnissen: VAS 0,5\u202f\u00b1\u20091,6; TAS 5,8\u202f\u00b1\u20092,2; Kujala 89,4\u202f\u00b1\u200912,5; KOOS 87,8\u202f\u00b1\u200914,1 und IKDC 86,7\u202f\u00b1\u200914,3. Insgesamt gaben 18\u00a0Patienten (90,0\u202f%) an, dass sie den Eingriff erneut durchf\u00fchren lassen w\u00fcrden. Zum Zeitpunkt der Nachuntersuchung waren 19\u00a0Patienten (95,0\u202f%) mit dem Operationsergebnis zufrieden. Ein Patient (m\u00e4nnlich, 23\u00a0Jahre alt) ben\u00f6tigte eine Revision. Keiner der eingeschlossenen Patienten hatte eine erneute Patellaluxation. Zusammenfassend l\u00e4sst sich schlie\u00dfen, dass die Parachute-Technik bei akuter Patellaluxation eine sehr gute klinische Funktion im kurz- bis mittelfristigen Follow-up aufweist.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s00064-024-00873-7","type":"journal-article","created":{"date-parts":[[2024,11,6]],"date-time":"2024-11-06T15:02:28Z","timestamp":1730905348000},"page":"354-362","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Refixierung von osteochondralen Flake-Frakturen nach Patellaluxation\u00a0\u2013 die Parachute-Technik","Refixation of osteochondral flake fractures after patellar dislocation\u2014The parachute technique"],"prefix":"10.1007","volume":"36","author":[{"given":"Romed P.","family":"Vieider","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebastian","family":"Siebenlist","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lorenz","family":"Fritsch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmed","family":"Ellafi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yannick","family":"Ehmann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julian","family":"Mehl","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,11,6]]},"reference":[{"key":"873_CR1","doi-asserted-by":"publisher","first-page":"1836","DOI":"10.1007\/s00167-016-4103-4","volume":"24","author":"EA Arendt","year":"2016","unstructured":"Arendt\u00a0EA, Berruto\u00a0M, Filardo\u00a0G, Ronga\u00a0M, Zaffagnini\u00a0S, Farr\u00a0J et\u00a0al (2016) Early osteoarthritis of the patellofemoral joint.
