However, factors such as patellar height (PH) and the sagittal plane's posterior tibial slope angle (PTSA) are potentially overlooked. This study investigated the impact of alignment correction angle guided by computer\u2010designed personalized surgical guide plate (PSGP) in MOWHTO on PH and PTSA, offering insights for enhancing surgical techniques.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This retrospective study included patients who underwent 3D\u2010printed PSGP\u2010assisted MOWHTO at our institution from March to September 2022. The paired t\u2010tests assessed differences in all preoperative and postoperative measurement parameters. Multivariate linear regression analysis examined correlations between PTSA, CDI (Caton\u2013Deschamps Index), and the alignment correction magnitude. Receiver operating characteristic (ROC) curve analysis determined the threshold of the correction angle, calculating sensitivity, specificity, and area under the curve.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 107 patients were included in our study. The CDI changed from a preoperative mean of 0.97\u2009\u00b1\u20090.13 (range 0.70\u20131.34) to a postoperative mean of 0.82\u2009\u00b1\u20090.13 (range 0.55\u20131.20). PTSA changed from a preoperative mean of 8.54\u2009\u00b1\u20092.67 (range 2.19\u201317.55) to a postoperative mean of 10.54\u2009\u00b1\u20093.05 (range 4.48\u201318.05).

A significant alteration in patellar height occurred when the correction angle exceeded 9.39\u00b0. Moreover, this paper illustrates a negative correlation between CDI change and the correction angle and preoperative PTSA. Holding other factors constant, each 1\u2010degree increase in the correction angle led to a 0.017 decrease in postoperative CDI, and each 1\u2010degree increase in preoperative PTSA resulted in a 0.008 decrease in postoperative CDI. PTSA change was positively correlated only with the correction angle; for each 1\u2010degree increase in the opening angle, postoperative PTS increased by 0.188, with other factors constant.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This study highlights the effectiveness and precision of PSGP\u2010assisted MOWHTO, focusing on the impact of alignment correction on PH and PTSA. These findings support the optimization of PSGP technology, which offers simpler, faster, and safer surgeries with less radiation and bleeding than traditional methods. However, PSGP's one\u2010time use design and the learning curve required for its application are limitations, suggesting areas for further research.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/os.14049","type":"journal-article","created":{"date-parts":[[2024,4,2]],"date-time":"2024-04-02T00:59:11Z","timestamp":1712019551000},"page":"1143-1152","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Changes in Patellar Height and Tibial Posterior Slope after Biplanar High Tibial Osteotomy with\n                    <scp>Computer\u2010Designed<\/scp>\n                    Personalized Surgical Guides: A Retrospective Study"],"prefix":"10.1111","volume":"16","author":[{"given":"Chang","family":"Liu","sequence":"first","affiliation":[{"name":"Tianjin Hospital  Tianjin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Luo","sequence":"additional","affiliation":[{"name":"Tianjin Hospital  Tianjin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianxiong","family":"Ma","sequence":"additional","affiliation":[{"name":"Tianjin Hospital  Tianjin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Songqing","family":"Ye","sequence":"additional","affiliation":[{"name":"Tianjin Hospital  Tianjin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bin","family":"Zhao","sequence":"additional","affiliation":[{"name":"Tianjin Hospital  Tianjin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haohao","family":"Bai","sequence":"additional","affiliation":[{"name":"Tianjin Hospital  Tianjin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fei","family":"Xing","sequence":"additional","affiliation":[{"name":"Tianjin Hospital  Tianjin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuan","family":"Jiang","sequence":"additional","affiliation":[{"name":"Tianjin Hospital  Tianjin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-8156-5562","authenticated-orcid":false,"given":"Xinlong","family":"Ma","sequence":"additional","affiliation":[{"name":"Tianjin Hospital  Tianjin China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,4]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00590-021-03043-8"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1177\/0363546511410025"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1155\/2019\/8363128"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1186\/s13643-021-01601-z"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620x.81b5.9590"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinbiomech.2017.10.021"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.87B9.15972"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1177\/0363546503258880"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-005-0700-3"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1054\/arth.2001.20538"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0171700"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-014-3821-5"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.5704\/MOJ.1303.009"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00264-009-0861-7"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-0037-1605561"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-007-0297-9"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.3390\/jpm13020292"},{"key":"e_1_2_10_19_1","doi-asserted-by":"publisher","DOI":"10.1186\/s40634-023-00647-3"},{"key":"e_1_2_10_20_1","doi-asserted-by":"publisher","DOI":"10.1111\/os.13440"},{"key":"e_1_2_10_21_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-0038-1669901"},{"key":"e_1_2_10_22_1","doi-asserted-by":"publisher","DOI":"10.1155\/2020\/1923172"},{"key":"e_1_2_10_23_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00264-019-04372-4"},{"key":"e_1_2_10_24_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00264-018-4207-1"},{"key":"e_1_2_10_25_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-015-3847-6"},{"key":"e_1_2_10_26_1","doi-asserted-by":"publisher","DOI":"10.1177\/23259671231200227"},{"key":"e_1_2_10_27_1","doi-asserted-by":"publisher","DOI":"10.1155\/2022\/7193902"},{"issue":"1","key":"e_1_2_10_28_1","first-page":"27","article-title":"La pente tibiale.
