Clinical Observation On Electroacupuncture Therapy For Pain After Total Knee Arthroplasty

Objective: In this experiment,by comparing and analyzing the relevant test data between the experimental group and the control group,we explored the analgesic effect of electroacupuncture on patients after Total knee arthroplasty(TKA),provided clinical and theoretical basis for further application of electroacupuncture in postoperative analgesia after total knee arthroplasty,and enriched the choice of postoperative analgesia modes.Methods: From November 2020 to December 2021,50 patients,aged between 40 and 80 years,who met the inclusion criteria and underwent the first unilateral total knee arthroplasty in the Department of Orthopedics,Shandong Provincial Hospital of Traditional Chinese Medicine,were randomly divided into experimental group and control group by random number table method.Control group: Patients were treated with unilateral femoral nerve block,intravenous patientcontrolled analgesia pump and oral celecoxib capsule.On the basis of the analgesic model of the control group,the experimental group was treated with electroacupuncture once a day 30 min minutes before functional exercise 1-7 days after operation.The VAS score,knee joint function score and knee joint active range of motion were recorded before and on the 2nd,3rd,5th and 7th day after operation,and the number of additional analgesic drugs used and the incidence of adverse reactions were counted.Results: On the 2nd,3rd,5th and 7th day after operation,the VAS scores of the experimental group were lower than those of the control group at rest and functional exercise,and the difference was statistically significant(P < 0.05).On the 3rd,5th and 7th day after operation,the knee joint function scores of the experimental group were higher than those of the control group,and the difference was statistically significant(P < 0.05).On the 2nd,3rd,5th and7 th day after operation,the active range of motion of knee joint in experimental group was higher than that in control group,and the difference was statistically significant(P < 0.05).Within 7 days after operation,there was no significant difference between the experimental group and the control group in the number of additional analgesic drugs used(P > 0.05).The incidence of nausea and vomiting in the experimental group was lower than that in the control group within 7 days after operation,and the difference was statistically significant(P < 0.05).Conclusion: Electro-acupuncture therapy can relieve the pain after total knee arthroplasty,enhance the analgesic effect,accelerate the recovery of postoperative joint function and reduce the occurrence of postoperative nausea and vomiting.
