Notes: Data in bold indicates statistical significance. Data presented as ROM score (range) (degrees), AOFAS score (range), VAS score (range), unless stated otherwise.
a
The comparisons between pre- and postoperative clinical measurements within groups: Wilcoxon Sign–Rank test, according to the Bonferroni correction; P<0.025 was considered statistically significant;
b
comparisons among groups in terms of differences in clinical measurements: Mann–Whitney U-test; P<0.05 was considered statistically significant.
Abbreviations: AOFAS, American Orthopedic Foot and Ankle Society; ROM, range of motion; VAS, visual analog scale.
