Comparison Of Early Outcomes Of Minimally Invasive Total Hip Arthroplasty With SuperPATH Approach And Conventional Posterolateral Approach

Objective:Incision length,compared with the traditional posterolateral approach and minimally invasive hip arthroplasty SuperPATH approach in bleeding and postoperative functional exercise time,operation time,postoperative Harris hip score before and after,comparative analysis of two kinds of surgical approach in the risk of intraoperative and postoperative and its curative effect.Methods:Methods a retrospective analysis of 86 cases of total hip arthroplasty between October 2015 and March 2017 was conducted,the longest follow-up period was 17 months,the shortest was 1 months,and the average follow-up time was 9.58 months.The cases were reviewed,analyzed and summarized by reviewing medical records,coming to the hospital,telephone and home visiting.The patients underwent minimally invasive total hip replacement(SuperPATH)as the observation group: 22 cases,14 males and 8 females,with an average age of(74.54±7.8)years.Right hip replacement in 13 cases,left hip replacement in 9 cases.BMI:17.5~31.7 kg/m2,the average is about 21.97 kg/m2.A total of 64 patients,31 males and 33 females,were treated with a conventional posterolateral approach as a control group.The mean age was(73.64±5.7)years.Right hip replacement in 34 cases,left hip replacement in 26 cases,bilateral hip replacement in 4 cases.BMI:15.1~34.1 kg/m2,the average is about 22.31 kg/m2.The operation time,incision length,intraoperative blood loss and early postoperative functional training time were recorded and recorded in two surgical approaches.SPSS 16 statistical software was used to analyze the results.The measurement data was expressed by difference in means,the data was checked by chi-square test,and the enumeration data was checked.The test level α =0.05,P < 0.05,the difference was statistically significant.Results:Through statistical analysis,the observation group and the control group in the operation time there was no significant difference in the comparison;the incision length,average incision length of the observation group(7.6±0.7)cm,compared with the control group(14.2±1.6)cm was statistically significant difference between the two groups(p<0.05);the two groups approach in intraoperative blood loss comparison,bleeding of the observation group was significantly lower than the control group,with significant difference between two groups(p<0.05);observation group of intraoperative bleeding was significantly less than the control group;before operation,one week after Harris hip rating two groups no difference in the statistical approach comparison.No postoperative joint dislocation,infection,and lower extremity venous thrombosis were found.Conclusion:The SuperPATH approach of minimally invasive hip joint has more advantages than the traditional posterolateral approach,such as the length of incision,the amount of bleeding during operation,and the weight-bearing exercises in the early stage.SuperPATH enters the intermuscular gap without injury to the external rotator muscle and tendon.It has a fast recovery,less risk of joint dislocation and good early clinical treatment.It is a common goal for both patients and doctors.However,the operation difficulty is larger than the traditional surgery,the learning cycle is long,and the long-term effect needs further follow-up.
