Abstract
Objective
To explore clinical efficacy of applying giant needle electroacupuncture at different times in improving pain and joint function after total knee arthroplasty(TKA).
Methods
A total of 120 patients who underwent TKA from July 2022 to March 2023 were included. They were divided into preoperative electro-acupuncture group, postoperative electro-acupuncture group, and control group according to different intervention times of electro-acupuncture, and 38 patients in each group, 2 patients from each group were dropped out, resulting in a final inclusion of 114 patients. In preoperative electro-acupuncture group, there were 7 males and 31 females;aged from 60 to 80 years old with an average of (72.0±5.8) years old;electro-acupuncture was performed on Weishu acupoint (ST32), Zusanli acupoint (ST36), Yinlingquan acupoint (SP9), and Yanglingquan acupoint (GB34) of non-operated lower limbs at 1 day before operation, 30 min before anesthesia induction, and 1 to 3 days after operation. In postoperative electro-acupuncture group, there were 9 males and 29 females;aged from 60 to 80 years old with average of (71.6±6.7) years old;the same acupuncture points and parameters were treated 1 to 3 days after operation. In control group, there were 6 males and 32 females;aged from 60 to 80 years old with an average of (71.6±7.1) years old;and were received pseudo-electroacupuncture treatment. Pain was scored at rest and during movement respectively before operation and 4 to 7 days after operation by using numerical rating scale at rest (NRSR) and numerical rating scale with movement (NRSM), joint function was evaluated by active range of motion (AROM) of knee joint, Hospital for Special Surgery(HSS) knee score, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC).
