Description The AA group received true AA by embedding vaccaria seeds at four specific AA points (knee joint, shenmen, subcortex, sympathesis) ipsilateral to the surgery site, while the control group received four nonacupuncture points on the auricular helix.
Experimental Description
Eventually, 90 degenerative osteoarthritis patients participated in this study and were randomly divided into two groups (AA group and sham control group) of 45 patients each.

Auxiliary Medication
All the patients in the two groups were provided the same epidural anesthesia, surgery was performed by the same group of surgeons, and the same prosthesis was used. Following surgery, each patient received the PCA pump for postoperative pain relief containing a mixture of fenta- nyl 0.8 mg, Crispin melanate (tramadol hydrochloride; Grunenthal Gmbh, Aachen, Germany) 800 mg, and 0.9% sodium chloride solution 400 mL. The PCA pump was set to continuously deliver 3 mL/1 h of the mixture and provide a single dose of 4 mL with a 30-minute lockout period pro re nata. The PCA pump was left connected to the patient until the third postoperative day. In addition, each patient was administered celecoxib 200 mg bid for 7 days. The same prophylactic antibiotics were routinely given, including one dose intraoperatively, and were con- tinued for 3 days postoperatively.

Description AA involved embedding vaccaria seeds (Vaccaria segetalis Garcke, known in China as Wang bu liu xing) on the auricular acupoints one day before surgery. Acupressure was applied by repeatedly pressing the acupoints with the fingertips for 3 minutes per point, four times per day, and ended 7 days after surgery.

Clinical Trial Type
A prospective, randomized, sham control trial comparing AA and a sham control.
Contraindications
Presence of a pacemaker,eczema of the ear or history of any previous surgery of the ear
Effector
VAS scores were similar at 12, 24, 36, and 48 h postsurgery (P > 0.05), but AA group scores were lower than those of the control group at 3, 4, 5, and 7 days (P < 0.05). Patients in the AA group consumed lower doses of analgesic than those in the control group after surgery (P < 0.05). The incidence of analgesia-related adverse effects in the AA group was lower than that in the control group (P < 0.05). Although HSS scores were similar in the two groups preoperatively and at 3 months postoperatively (P > 0.05), HSS scores 2 weeks postoperatively were higher in the AA group than in the control group (P < 0.05), but there was no difference between groups in ROM (P > 0.05).
Auricular acupressure for analgesia in perioperative period of total knee arthroplasty.
Abstract
OBJECTIVE: We examined whether auricular acupressure (AA) can alleviate postoperative pain and decrease narcotic consumption and its adverse effects for osteoarthritis patients after total knee arthroplasty (TKA). DESIGN: A prospective, randomized, sham control trial comparing AA and a sham control. SETTING: Department of Orthopedics, the first Hospital affiliated to Zhejiang University of Traditional Chinese Medicine, Hangzhou, China. SUBJECTS: Ninety patients with degenerative osteoarthritis undergoing TKA. INTERVENTIONS: The AA group received true AA by embedding vaccaria seeds at four specific AA points (knee joint, shenmen, subcortex, sympathesis) ipsilateral to the surgery site, while the control group received four nonacupuncture points on the auricular helix. OUTCOME MEASURES: Visual analog scale (VAS), the consumption of analgesic via patient-controlled analgesia, the incidence of analgesia-related adverse effects, Hospital for Special Surgery scores (HSS), and range of motion (ROM) were recorded. RESULTS: VAS scores were similar at 12, 24, 36, and 48 h postsurgery (P > 0.05), but AA group scores were lower than those of the control group at 3, 4, 5, and 7 days (P < 0.05). Patients in the AA group consumed lower doses of analgesic than those in the control group after surgery (P < 0.05). The incidence of analgesia-related adverse effects in the AA group was lower than that in the control group (P < 0.05). Although HSS scores were similar in the two groups preoperatively and at 3 months postoperatively (P > 0.05), HSS scores 2 weeks postoperatively were higher in the AA group than in the control group (P < 0.05), but there was no difference between groups in ROM (P > 0.05). CONCLUSIONS: Applying auricular acupoint acupressure in the perioperative period of TKA is favorable for alleviating postoperative pain, decreasing opioid consumption and its adverse effects, and promoting early rehabilitation. Also, this intervention has the advantage of lower costs, fewer complications, simple application, and high safety."
