Outcome was evaluated retrospectively after a minimum follow-up of 24\u00a0months using KT-1000 arthrometer measurements, clinical examination, outcome scores (Lysholm score, Tegner Activity Scale), and a questionnaire about sport activities.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>A total of 23 patients (44% male, 57% female) with a mean age of 25\u2009\u00b1\u200915\u00a0years were included. Mean follow-up was 57\u2009\u00b1\u200925\u00a0months. KT-1000 arthrometer measurements of anterior tibial translation revealed a mean side-to-side difference of 0.9\u2009\u00b1\u20091.0\u00a0mm. Clinical examination showed 100% normal or nearly normal anterior translation of the tibia. Two patients (9%) received an ACL reconstruction due to traumatic ACL re-instability and were, therefore, considered as failures. An extension deficit concerning hyperextension occurred in 29% of patients postoperatively. Further postoperative complications occurred in 14% of patients and included postoperative stiffness with ROM limitations and secondary dislocation of a fragment. Mean postoperative Lysholm score was 89\u2009\u00b1\u200914. Comparing pre- and postoperative values, no significant change of the Tegner Activity Scale was observed. All patients (failures excluded) returned to high impact sports activities after ARIF.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Excellent reliable ligamentous stability and high rates of return to high impact sports can be expected after ARIF using a suture fixation technique for type II\u2013IV tibial eminence fractures. Complications, such as limitations in ROM, commonly occur in up to 30% after ARIF. Therefore, regular follow-up examinations remain important in this usually young patient cohort.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Level of Evidence<\/jats:title>\n                <jats:p>Level IV.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s00402-021-03961-6","type":"journal-article","created":{"date-parts":[[2021,5,19]],"date-time":"2021-05-19T10:02:52Z","timestamp":1621418572000},"page":"3623-3631","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Reliable ligamentous stability and high return-to-sport rates after arthroscopic reduction and internal fixation of tibial eminence fractures"],"prefix":"10.1007","volume":"142","author":[{"given":"Patricia M.","family":"Lutz","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephanie","family":"Geyer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philipp W.","family":"Winkler","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Markus","family":"Irger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel P.","family":"Berthold","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthias J.","family":"Feucht","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreas B.","family":"Imhoff","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philipp","family":"Forkel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,5,19]]},"reference":[{"key":"3961_CR1","doi-asserted-by":"publisher","first-page":"2562","DOI":"10.1016\/j.arthro.2016.04.031","volume":"32","author":"A Achtnich","year":"2016","unstructured":"Achtnich A, Herbst E, Forkel P, Metzlaff S, Sprenker F, Imhoff AB et al (2016) Acute proximal anterior cruciate ligament tears: outcomes after arthroscopic suture anchor repair versus anatomic single-bundle reconstruction.
