Study on the effect of analgesia on the recovery of joint function during rehabilitation exercise of total knee arthroplasty
Objective To explore the effect of analgesia on the recovery of joint function during rehabilitation exercise of total knee arthroplasty.Methods A total of 70 patients receiving total knee arthroplasty were divided into a control group and an experimental group according to different types of analgesia during rehabilitation exercise,with 35 cases in each group.The control group was given normal saline,and the experimental group was given femoral nerve block analgesia.Comparison was made on visual analogue scale(VAS)score of resting and motion after extubation,24 h postoperatively,48 h postoperatively,and 72 h postoperatively,VAS score of rehabilitation exercise at 4-7 d postoperatively,continuous passive motion(CPM)angle at 4-7 d postoperatively,the time for the joint CPM to reach the discharge target angle,and the score of the Knee Surgery Society(KSS)between the two groups.Results There was no statistically significant difference between the two groups in VAS score of resting and motion after extubation,24 h postoperatively,48 h postoperatively,and 72 h postoperatively(P>0.05).At 4-7 d postoperatively,the VAS scores of rehabilitation exercise were(2.41±0.62),(2.78±0.71),(2.71±0.76)and(2.13±0.72)points,which were significantly lower than(3.56±0.94),(3.89±1.04),(3.71±0.83)and(3.68±0.81)points in the control group,and the difference was statistically significant(P<0.05).At 4-7 d postoperatively,the CPM angles were(81.32±8.81),(92.09±8.37),(99.61±7.45)and(105.12±6.23)°,which were significantly higher than(59.03±9.53),(70.73±8.49),(81.43±7.58)and(90.48±7.21)° in the control group(P<0.05).The time for the joint CPM to reach the discharge target angle was(4.91±0.84)d in the experimental group and(7.06±0.64)d in the control group,and the difference between the two groups was statistically significant(P<0.05).There was no statistical significance in clinical and functional scores between the two groups(P>0.05).Conclusion Femoral nerve block analgesia during rehabilitation exercise of total knee arthroplasty has positive effect on joint function recovery.
