Abstract Objective To compare the short-term clinical efficacy between the SuperPATH minimally invasive approach and the anterior lateral small incision.approach in total hip arthroplasty.Methods From Feb 2015 to Feb 2017,80 patients undrwent THA were involved.All cases were randomly divided into 2 groups.40 cases were treated by using SuperPATH approach as Super PATH group,while another 40 cases were treated by using anterolateral small incision approach as small incision group.The length of incision,operative time,intraoperative bleeding,postoperative drainage,hospitalization time,abduction angle and anteversion angle time were compared between the two groups.The visual pain analogue score(VAS)before operation and the VAS score of 1 day,days,1month and 3 months after operation and the Harris score of hip function before operation,and in 7 days,1 month and 6 months after operation were compared between the two groups.Results In SuperPATH group,the incision length was smaller than that of the anterior lateral small incision group(P<0.05);The hemorrhage,postoperative drainage and hospitalization time in SuperPATH group were less than those in the anterior lateral small incision group,and the difference was statistically significant(P<0.05),but SuperPATH group had longer operation time than the small incision group(P<0.05).Compared with the small incision group,the patient in the SuperPATH suffered less pain within 1day and 7days(P<0.05),similar pain in 1month and 3 months(P>0.05).The SuperPATH group's Harris hip score was increased significantly than small incision group from 7days,1 month and 3months after surgery(P<0.05),However,there was no significant difference in hip function between the two groups from 6 months after surgery(P>0.05).And there was no significant difference of abduction angle and angle of anteversion between 2 groups.Conclusion Both SuperPATH approach and anterolateral small incision approach can obtain good hip function in THA,but Super PATH approach can obtain a good joint stability,less trauma,faster postoperative recovery,but which influence on long-term effect needs further follow-up.
