Total knee arthroplasty using the Midvastus approach with a half tourniquet facilitate recoveries better： a retrospective study

Abstract

Abstract Purpose This research aimed to compare recovery outcomes in patients undergoing total knee arthroplasty(TKA) with a half-course tourniquet using the midvastus(MV) approach and the medial parapatellar(MP) approach.Methods Patients receiving TKA treatment (MV or MP) were retrospectively recruited in this study between June 2019 to June 2022. The demographic, perioperative, and patient satisfaction data were collected and compared between MV and MP groups.Results A retrospective study of 112 patients who underwent total knee replacement between June 2019 and June 2022 was divided into two groups according to different surgical approaches, including the MV approach (59 cases) and the MP approach (53 cases). General data (age, sex, height, weight, BMI, education level, VAS score, HSS score), intraoperative data(incision length, operation time, intraoperative blood loss) and postoperative data(postoperative drainage volume, hemoglobin difference before and after surgery, time of first postoperative landing, postoperative hospital stay, VAS score and HSS score in the first week, one month and three months after surgery), as well as the number of blood transfusion cases, the number of surgical complications, and satisfaction were collected.Conclusions Both the midvastus approach and the medial parapatellar approach were able to complete the knee replacement and improve the patients’ knee function, and the medial femoral approach was beneficial for the patients’ early recovery, but there was no significant difference in knee function, complications, and satisfaction between the two groups at 3 months after surgery.
