Abstract: ［Abstract］〓Objective〖HTSS〗〓To observe the clinical effective of direct anterior approach(DAA) and the anterolateral approach(ALA) in total hip arthroplasty(THA).
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓Retrospective analysis of 132 patients who undergoing THA in our hospital was used. According to the surgical approach, they were divided into ALA group(79 cases) and DAA group(53 cases). The related data especially complications in intraoperative and postoperative was observed and analyzed. The intraoperative and postoperative data between the 2 groups was observed, especially the occurrence of perioperative complications. 
〖HTH〗〖WTHZ〗Results〖HTSS〗〓Patients in DAA group had shorter incision length, partial weight time and hospitalization than those in ALA group. The intraoperative blood loss and postoperative drainage were less than those in ALA group. The difference was statistically significant(P＜005). There was no statistical difference in the operation time between the two groups(P＞005). The VAS scores in both groups showed a gradual decrease and DAA group had a lower VAS score than ALA group. Harris hip function score showed a gradual increase trend after surgery, and the score in DAA group was higher than that in ALA group(P＜005). The hip function in DAA group was better than that that in ALA group. The rate of excellent and good of hip function in DAA group was significantly higher than that of ALA group(P＜005). There was no significant difference in perioperative complications between the 2 groups(P＞005).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓Compared with ALA, DAA has the characteristic of less traumatic, little intraoperative and postoperative blood loss, short hospital stay, and good joint function recovery. It is suitable for experienced senior doctors to carry out.
