Abstract:
Objective To observe the joint function and life quality in total hip arthroplasty (THA) through SuperPath approach, and compare randomly to traditional posterolateral approach in THA. Methods According to random number table, 54 patients who needed THA were randomly divided into observation group (SuperPath approach) and control group (traditional posterolateral approach), each group included 27 cases. Preoperative and postoperative Harris hip score, time of timed-up-and-go, time of single-limb stance, distance of 6 -minute walk test, ambulation time, length of stay, SF- 36 score and complications in two groups were recorded and compared. Results The Harris hip scores of 1 week and 3 months after operation in observation group (70.5±5.6 and 83.1±5.5) were signi?cantly higher than those in control group (63.8±6.1 and 78.0±5.6) (P<0.05), but had no statistical sense in 6 months and 12 months after operation (P>0.05). Compared to control group, the time of timed-up-and-go of 1 month and 3 months after operation [(36.5±7.3) s and (24.4±4.9) s] were shorter, the time of single-limb stance of 1 months after operation [(14.4 ±3.6) s] was longer, and the distance of 6 -min walk test of 3 months after operation [(395. 1± 27. 7 ) m] was farther, the differences were statistically signi?cant (P <0.05). Ambulation time and length of stay in observation group[(20.0±3.6) h and (9.7± 2. 8) d] were signi?cantly shoter than control group [(33.2±5.4) h and (13.2±3.7) d] (P<0.05).After 12 months of operation, the scores of mental health and general health in observation group (78.1±9.3 and 82.0±8.8) were signi?cantly higher than control group (73.1±8.7 and 76.3±10.2) (P<0.05), but had no statistical sense on the scores of body pain and social function between the two groups (P>0.05). Two cases of asymptomatic deep venous thrombosis were observed in the control group. Conclusion Compared to traditional posterolateral approach, the THA through SuperPath approach can improve the joint function and life quality more effectively, and conform to the idea of fast track surgery.
