The aim of this study was to examine whether a larger correction angle in medial open wedge high tibial osteotomy (MOWHTO) leads to greater changes in postoperative patellar height (PH) and posterior tibial slope (PTS). Methods: Data from 83 patients who underwent MOWHTO were retrospectively analyzed. Lower limb alignment was evaluated using the hip\u2013knee\u2013ankle angle (HKAA). The PH was assessed using the Insall\u2013Salvati index (ISI), the Blackburne\u2013Peel index (BPI), the Caton\u2013Deschamps index (CDI), the modified Miura\u2013Kawamura index (MKI), and the plateau\u2013patella angle (PPA). The PTS was determined using the Moore\u2013Harvey method. Results: The median correction of HKAA was 8\u00b0. A decrease in PH was observed in the majority of cases across all methods, with the highest frequency of postoperative patella infera detected using the MKI. PTS most frequently increased, with a median increase of 3\u00b0. A significant association between the magnitude of HKAA correction and patellar height in the overall cohort was observed only for the MKI, whereas in patients with an HKAA correction \u2265 10\u00b0, significant associations were found for both the MKI and CDI. No significant association was found between the magnitude of HKAA correction and changes in posterior tibial slope in the overall cohort, while a significant negative correlation was observed in patients with an HKAA correction \u2265 10\u00b0. Conclusions: Assessment using the MKI demonstrated greater sensitivity in detecting postoperative PH decrease, particularly in identifying patella infera. The magnitude of HKAA correction was significantly associated with greater changes in PTS and PH in patients with a coronal plane correction of \u226510\u00b0.<\/jats:p>","DOI":"10.3390\/jcm15041469","type":"journal-article","created":{"date-parts":[[2026,2,13]],"date-time":"2026-02-13T09:09:19Z","timestamp":1770973759000},"page":"1469","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Magnitude of Varus Correction and Its Influence on Postoperative Patellar Height and Posterior Tibial Slope in Medial Open-Wedge High Tibial Osteotomy"],"prefix":"10.3390","volume":"15","author":[{"given":"Veljko","family":"Santic","sequence":"first","affiliation":[{"name":"Lovran Orthopedic Clinic, Faculty of Medicine, University of Rijeka, 51415 Lovran, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0994-123X","authenticated-orcid":false,"given":"Nikola","family":"Matejcic","sequence":"additional","affiliation":[{"name":"Lovran Orthopedic Clinic, Faculty of Medicine, University of Rijeka, 51415 Lovran, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marta","family":"Santic","sequence":"additional","affiliation":[{"name":"Lovran Orthopedic Clinic, 51415 Lovran, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9141-1830","authenticated-orcid":false,"given":"Nikola","family":"Grzalja","sequence":"additional","affiliation":[{"name":"Lovran Orthopedic Clinic, Faculty of Medicine, University of Rijeka, 51415 Lovran, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3849","DOI":"10.1007\/s00167-020-05857-1","article-title":"Opening wedge high tibial osteotomy allows better outcomes than unicompartmental knee arthroplasty in patients expecting to return to impact sports","volume":"28","author":"Jacquet","year":"2020","journal-title":"Knee Surg.
