Abstract:Objective To evaluate the analgesic effect of single-shot femoral nerve block combined with periarticular injection after total knee arthroplasty.Methods 50 patients with total knee arthroplasty were selected from January 2017 to May 2018 in our hospital.There were 22 males and 28 females.The patients were 60 to 80 years old and the average age was(69.90±9.46).All of them were divided into the experimental group of combined periarticular injection of analgesia and single-shot femoral nerve block,or the control group of single-shot femoral nerve block alone group randomly.There were 25 cases in each group.The VAS score at rest and in activity,ROM,the rate of adverse reactions after operation was compared between the two groups.Results The experimental group had significantly lower VAS score than the control group at 6,12,24,48h both at rest and in activity (P<0.05).The ROM in the experimental group were also significantly better than the control group at 1 and 2 days after the operation,while there was on difference in the ROM at 3 and 7 days after the operation between the two groups (P>0.05),and there was no significant difference in postoperative complications between the two groups(P>0.05).Conclusion Combination of periarticular injection of analgesia and single-shot femoral nerve block is more effective than femoral nerve block alone in relieving early postoperative pain,which indeed helpful to early functional exercise.And there was no increase in postoperative complications.However,no significant advantage for long-term functional recovery has been found.
