The Kruskal–Wallis test was used for all the variables, except for VAS- (visual analogue scale-) estimated pain at rest and during activity and preoperative McGowan grade, where one-way ANOVA and chi-square statistics were applied, respectively. Statistically significant differences are marked in bold. Values are mean (SD), percentage, and count n.
