Nevertheless, the appropriate approach for addressing this parameter remains unclear so far. One potential approach for correcting tibiofemoral rotation is femoral rotational osteotomy. We hypothesized that femoral rotational osteotomy affects tibiofemoral rotation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>All patients who underwent femoral rotational osteotomy between January 2018 and May 2022 were included in this study. Pre\u2010 and postoperative tibiofemoral rotation and the degree of femoral rotation were measured using two\u2010dimensional (2D) and three\u2010dimensional (3D) measurements. The effect of femoral rotation on tibiofemoral rotation was assessed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Forty knees (18 right\u00a0and 22 left) of 36 patients (28 females\u00a0and 8 males) were included. Mean preoperative femoral torsion was 32.1\u2009\u00b1\u200910.1\u00b0 in 2D and 30.8\u2009\u00b1\u200910.1\u00b0 in 3D. Femoral rotation was performed by \u221214.1\u2009\u00b1\u20098.3\u00b0 using 2D measurements and \u221215.0\u2009\u00b1\u20098.0\u00b0 using 3D measurements. Tibiofemoral rotation changed from 9.9\u2009\u00b1\u20096.2\u00b0 to 9.7\u2009\u00b1\u20096.0\u00b0 (<jats:italic>p<\/jats:italic>\u2009=\u2009n.s.) in 2D, and from 10.2\u2009\u00b1\u20095.5\u00b0 to 9.4\u2009\u00b1\u20095.4\u00b0 (<jats:italic>p<\/jats:italic>\u2009=\u2009n.s.) in 3D.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Tibiofemoral rotation showed no significant changes after femoral rotational osteotomy. Hence, femoral rotational osteotomy cannot be used to correct tibiofemoral rotation in addition to correcting the femoral version. Other surgical techniques need to be evaluated if correction of tibiofemoral rotation is required.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of Evidence<\/jats:title><jats:p>Level III.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ksa.12250","type":"journal-article","created":{"date-parts":[[2024,5,7]],"date-time":"2024-05-07T15:39:36Z","timestamp":1715096376000},"page":"2213-2218","source":"Crossref","is-referenced-by-count":16,"title":["No significant change of tibiofemoral rotation after femoral rotational osteotomy in patients with patellofemoral instability"],"prefix":"10.1002","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8128-3927","authenticated-orcid":false,"given":"Lukas","family":"Jud","sequence":"first","affiliation":[{"name":"Department of Orthopedics, Balgrist University Hospital University of Zurich Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vanessa","family":"Klenecky","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Balgrist University Hospital University of Zurich Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Georgios","family":"Neopoulos","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Balgrist University Hospital University of Zurich Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jakob","family":"Ackermann","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Balgrist University Hospital University of Zurich Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandro F.","family":"Fucentese","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Balgrist University Hospital University of Zurich Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lazaros","family":"Vlachopoulos","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Balgrist University Hospital University of Zurich Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,5,7]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.1177\/2325967118S00076"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF01552649"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-199706000-00020"},{"key":"e_1_2_12_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/ksa.12015"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-022-06971-y"},{"key":"e_1_2_12_7_1","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.E.01130"},{"key":"e_1_2_12_8_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12891-021-04633-7"},{"key":"e_1_2_12_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-022-07150-9"},{"key":"e_1_2_12_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/ksa.12151"},{"key":"e_1_2_12_11_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00264-020-04496-y"},{"key":"e_1_2_12_12_1","doi-asserted-by":"publisher","DOI":"10.1097\/00042752-199201000-00004"},{"key":"e_1_2_12_13_1","doi-asserted-by":"publisher","DOI":"10.2307\/2529310"},{"key":"e_1_2_12_14_1","doi-asserted-by":"publisher","DOI":"10.1177\/03635465231163856"},{"key":"e_1_2_12_15_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-020-06382-x"},{"key":"e_1_2_12_16_1","doi-asserted-by":"publisher","DOI":"10.1002\/ksa.12033"},{"key":"e_1_2_12_17_1","doi-asserted-by":"publisher","DOI":"10.1002\/ksa.12097"},{"key":"e_1_2_12_18_1","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.N.01313"},{"key":"e_1_2_12_19_1","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.17.00863"},{"key":"e_1_2_12_20_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-2008-1033007"},{"key":"e_1_2_12_21_1","doi-asserted-by":"publisher","DOI":"10.1111\/os.13358"},{"key":"e_1_2_12_22_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-023-07476-y"}],"container-title":["Knee Surgery, Sports Traumatology, Arthroscopy"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/esskajournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ksa.12250","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,19]],"date-time":"2025-10-19T14:12:56Z","timestamp":1760883176000},"score":1,"resource":{"primary":{"URL":"https:\/\/esskajournals.onlinelibrary.wiley.com\/doi\/10.1002\/ksa.12250"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,5,7]]},"references-count":21,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2024,9]]}},"alternative-id":["10.1002\/ksa.12250"],"URL":"https:\/\/doi.org\/10.1002\/ksa.12250","archive":["Portico"],"relation":{},"ISSN":["0942-2056","1433-7347"],"issn-type":[{"value":"0942-2056","type":"print"},{"value":"1433-7347","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,5,7]]}}}
