Abstract
Objective:To investigate the effect of inferior femoral medialis approach on patients undergoing total knee arthroplasty(TKA).Methods:Data of 84 patients who underwent TKA surgery in Peking University Medical Zibo Hospital from July 2022 to April 2024 were retrospectively analyed,and were divided into a vastus medialis muscle group and a conventional group according to different approach methods,with 42 cases in each group.The vastus medialis muscl group was treated with the inferior femoral medialis approach,while the conventional group was treated with the medial parapatellar approach.The operative indicators,pain degree,joint movement and joint function were compared between the two groups.Results:The total operation time of the vastus medialis muscle group was longer than that of the conventional group,and the incision length was shorter than that of the conventional group,the differences were statistically significant(P<0.05);there were no significant differences between the two groups in the amount of intraoperative blood loss and the decrease of hemoglobin 3 days after surgery(P>0.05).At 3 days after surgery,the Pain Visual Analogue Scale(VAS)score of the vastus medialis muscle group was lower than that of the conventional group,the difference was statistically significant(P<0.05);at 6 weeks after surgery,there was no significant difference in VAS scores between the two groups(P>0.05).The earliest leg lift time and 90° flexion time in the vastus medialis muscle group were(27.67±5.13)h and(31.60±6.09)h,respectively,which were earlier than(34.83±5.70)h and(37.94±5.79)h in the conventional group,the differences were statistically significant(P<0.05);there was no significant difference in knee joint motion 6 months after surgery between the two groups(P>0.05).The excellent and good rate of joint function in the vastus medialis muscle group was 73.81%,compared with 66.67%in conventional group,there was no significant difference(P>0.05).Conclusion:For TKA patients,different approaches have no significant impact on the long-term recovery of joint function.Although the inferior femoral medialis approach slightly increases the operation time,but the early pain degree is lower,the incision length is shorter,and patients regain movement in their joints earlier.关键词
