^*The independent t test was used to analyze differences in age, BMI, hemoglobin, albumin, platelets, and follow-up duration. The Chi-square or Fisher’s exact test was used to analyze differences in sex, diabetes, current smoker, antithrombotic drug use, and preoperative diagnosis between the groups. A p-value of < 0.05 was considered significant
^†The values are given as the mean ± standard deviation, with the range in parentheses
^‡The values are given as the number of ankles, with the percentage in parentheses
