Statistical analysis was performed using SPSS for Statistics (Version 29; IBM). For continuous variables the mean ± SD was used. The mean differences among the 3 SSD groups (<3, 3-5, ≥6 mm) were compared with the Kruskal-Wallis test, with the Dunn test for comparison of ≥2 groups and for nonnormally distributed parameters due to nonnormal distribution of the values. Categorical parameters were compared using the chi-square test. In case of small subgroups (n < 5), the Fisher exact text was used for categorical parameters. A P value of <.05 was considered significant.
In addition, we performed multiple linear regression analysis to identify predictors for reduced postoperative IKDC score after revision ACLR, including SSD of 3 to 5 mm, SSD ≥6 mm, body mass index (BMI), and medial meniscal lesions. Medial meniscal lesion and obesity were chosen as independent variables in the multiple linear regression analysis, as they are proven in the literature to be related to a worse functional outcome.4 (link)
