| More Details: | Objective Medial opening‐wedge high tibial osteotomy (MOWHTO) is a surgical procedure to treat medial compartment osteoarthritis in the knee with varus deformity. 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‐designed personalized surgical guide plate (PSGP) in MOWHTO on PH and PTSA, offering insights for enhancing surgical techniques. Methods This retrospective study included patients who underwent 3D‐printed PSGP‐assisted MOWHTO at our institution from March to September 2022. The paired t‐tests assessed differences in all preoperative and postoperative measurement parameters. Multivariate linear regression analysis examined correlations between PTSA, CDI (Caton–Deschamps 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. Results A total of 107 patients were included in our study. The CDI changed from a preoperative mean of 0.97 ± 0.13 (range 0.70–1.34) to a postoperative mean of 0.82 ± 0.13 (range 0.55–1.20). PTSA changed from a preoperative mean of 8.54 ± 2.67 (range 2.19–17.55) to a postoperative mean of 10.54 ± 3.05 (range 4.48–18.05). The t‐test revealed statistically significant changes in both values (p |
