Exclusion criteria were history of fracture, trauma, or orthopaedic surgery; developmental dysplasia of the hip or femoral head necrosis; femoral bowing deformity; deformity of the tibial shaft; and leg length discrepancy. Using standing whole\u2010leg radiographs, an OWHTO simulation was performed to determine the Miniaci angle by delivering the WBL to the Fujisawa point. The relationship of the Miniaci angle, the presurgery parameters, and the changes in presurgery parameters were analyzed by Spearman's correlation and linear regression analyses. The relationship between the postsurgery HKA angle and presurgery parameters was analyzed by multiple linear regression model.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The Miniaci angle showed a near\u2010perfect correlation with the presurgery HKA angle (y\u00a0=\u00a0\u22121.05x\u00a0+ 192.10, r\n                      <jats:sup>2<\/jats:sup>\n                      \u00a0= 0.99), presurgery WBL percentage (y\u00a0=\u00a0\u22120.25x\u00a0+ 15.14, r\n                      <jats:sup>2<\/jats:sup>\n                      \u00a0= 0.97), \u0394HKA angle (y\u00a0= 1.04x\u00a0\u2212 0.03, r\n                      <jats:sup>2<\/jats:sup>\n                      \u00a0= 1.00), \u0394WBL percentage (y\u00a0= 0.25x\u00a0\u2212 0.52, r\n                      <jats:sup>2<\/jats:sup>\n                      \u00a0= 0.97), and \u0394mMPTA (y\u00a0= 1.04x\u00a0\u2212 0.03, r\n                      <jats:sup>2<\/jats:sup>\n                      \u00a0= 1.00).

With the conversion formulas determined in the current study, surgeons can calculate the Miniaci angle based on the presurgery parameters without the assistance of digital software for complex surgical simulation. The Miniaci angle is closely related to the gap of the medial opening wedge. Based on the Miniaci angle and the depth of the osteotomy, surgeons can calculate the gap required before surgery using trigonometric functions and then simply measure the gap during surgery.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1016\/j.arthro.2022.11.007","type":"journal-article","created":{"date-parts":[[2022,11,8]],"date-time":"2022-11-08T20:47:00Z","timestamp":1667940420000},"page":"1222","update-policy":"https:\/\/doi.org\/10.1016\/elsevier_cm_policy","source":"Crossref","is-referenced-by-count":10,"title":["Pre\u2010Surgery Hip\u2010Knee\u2010Ankle Angle and Weightbearing Line Percentage Are Nearly Perfectly Correlated to the Miniaci Angle When Planning Open Wedge High Tibial Osteotomies"],"prefix":"10.1002","volume":"39","author":[{"given":"Xu","family":"Jiang","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery Sun Yat\u2010Sen Memorial Hospital Sun Yat\u2010Sen University Guangzhou Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Di","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery Sun Yat\u2010Sen Memorial Hospital Sun Yat\u2010Sen University Guangzhou Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bo","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery Sun Yat\u2010Sen Memorial Hospital Sun Yat\u2010Sen University Guangzhou Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mengning","family":"Yan","sequence":"additional","affiliation":[{"name":"Shanghai Key Laboratory of Orthopaedic Implants Department of Orthopaedic Surgery Shanghai Ninth People's Hospital Shanghai Jiao Tong University School of Medicine Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xumin","family":"Hu","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery Sun Yat\u2010Sen Memorial Hospital Sun Yat\u2010Sen University Guangzhou Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liao","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery Sun Yat\u2010Sen Memorial Hospital Sun Yat\u2010Sen University Guangzhou Shanghai China"},{"name":"Shanghai Key Laboratory of Orthopaedic Implants Department of Orthopaedic Surgery Shanghai Ninth People's Hospital Shanghai Jiao Tong University School of Medicine Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liangbin","family":"Gao","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery Sun Yat\u2010Sen Memorial Hospital Sun Yat\u2010Sen University Guangzhou Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,11,8]]},"reference":[{"key":"e_1_2_4_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-012-2087-2"},{"key":"e_1_2_4_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2020.11.008"},{"key":"e_1_2_4_4_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546518758016"},{"key":"e_1_2_4_5_2","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-199201000-00025"},{"key":"e_1_2_4_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0030-5898(20)30753-7"},{"key":"e_1_2_4_7_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-198769030-00005"},{"key":"e_1_2_4_8_2","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-198909000-00035"},{"key":"e_1_2_4_9_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-016-4092-3"},{"key":"e_1_2_4_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.knee.2020.01.007"},{"key":"e_1_2_4_11_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-015-3954-4"},{"key":"e_1_2_4_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.knee.2019.10.018"},{"key":"e_1_2_4_13_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-019-05637-6"},{"key":"e_1_2_4_14_2","unstructured":"Jiang X Li B Xie K et\u00a0al.
