  1. aBecause the data is skewed distribution, it was represented by median (quartile range) and compared by Mann–Whitney U test. The enumeration data was compared by Fischer’s exact test as the small size. Johner-Wruhs scores was shown by excellent and good rate, besides, all the postoperative complications were venous thrombosis
