Auxiliary Medication
All the patients in this study received standardized general anesthesia with propofol (2 mg/kg) and fentanyl (2 μg/kg). Orotracheal intubation was facilitated with vecuronium (0.15 mg/kg). Subsequent doses of 0.5 to 1 μg/kg fentanyl were added when necessary, except during the last 30 minutes of surgery.

Description Electroacupuncture stimulation (transcutaneous electrical nerve stimulation Model-05B; Ching Ming Medical Device Co, Ltd, Taiwan) was composed of 2 channels linked to SP10-LR7 and ST36-ST34, respectively (100 and 10 Hz alternately for 20 minutes). Muscle twitch was induced at the time of electroacupuncture stimulation. After the acupuncture procedure was completed,the needles were removed before the patient recovered from general anesthesia

Adverse Effects
there were no wound complications related to acupuncture or TKA in the study and control groups.
Contraindications
Presence of systemic or local infections
Effector
This study comprised 60 patients (30 in the study group and 30 in the control group). The fentanyl requirement via patient-controlled analgesia in the study group was lower [mean (SD), 620.7 (258.2) vs 868.6 (319.3) μg; P = 0.002). The time to first request for fentanyl was longer in the study group. Pain intensity on a 100-mm visual analog scale was lower in the study group in the first 24 hours after the operation. The incidence of analgesia-related adverse effects of nausea and vomiting was lower in the study group. The success of blinding was not significantly different between the 2 groups (P= 0.731). The data obtained from this clinical trial demonstrate the potential advantages of using acupuncture for postoperative pain control after total knee arthroplasty.
Acupuncture for pain relief after total knee arthroplasty: a randomized controlled trial.
Abstract
BACKGROUND AND OBJECTIVES: The effectiveness of acupuncture in relieving acute postoperative pain is still controversial. This patient-evaluator blinded and sham auricular acupuncture (AA)-controlled study tested whether acupuncture is effective in controlling acute postoperative pain after total knee arthroplasty. METHODS: Patients were randomly assigned to receive true acupuncture (knee, scalp, and AA) or sham AA. All procedures were conducted under general anesthesia, and the AA needles were retained in situ for 3 days. Postoperative pain was managed with intravenous fentanyl using a patient-controlled analgesia pump. The amount of postoperative fentanyl required, the time to the first fentanyl request, pain intensity on a 100-mm visual analog scale, incidence of analgesia-related adverse effects, and success of patients' blinding were recorded. RESULTS: This study comprised 60 patients (30 in the study group and 30 in the control group). The fentanyl requirement via patient-controlled analgesia in the study group was lower [mean (SD), 620.7 (258.2) vs 868.6 (319.3) mug; P = 0.002). The time to first request for fentanyl was longer in the study group. Pain intensity on a 100-mm visual analog scale was lower in the study group in the first 24 hours after the operation. The incidence of analgesia-related adverse effects of nausea and vomiting was lower in the study group. The success of blinding was not significantly different between the 2 groups (P = 0.731). CONCLUSIONS: The data obtained from this clinical trial demonstrate the potential advantages of using acupuncture for postoperative pain control after total knee arthroplasty."
