Knee osteoarthritis (KOA), also called degenerative knee disease, is one of the most common bone and joint diseases in clinic. It was estimated to affect more than 9 million individuals in the United States in 2005 and is a leading cause of disability and medical costs. Most elderly people over the age of 65 have radiographic and/or clinical evidence of osteoarthritis. KOA is a lifelong disease which can lead to obvious pain, joint stiffness, limitation of activity and even joint failure or disability. Acupuncture is a popular treatment taken from ancient Chinese medicine, in which fine needles are placed into the body at specific points. Studies have shown that acupuncture can stimulate nerves under the skin, causing the body to produce natural pain-relieving substances (endorphins). However the evidences of acupuncture for KOA are contradictory. According to the review, intensive acupuncture with three sessions a week is more effective for KOA than sparse acupuncture with one session a week. Moreover, the papers published in the past years suggest that manual acupuncture and electro-acupuncture are most commonly used acupuncture therapy for the treatment of knee osteoarthritis. The aim of this study is to evaluate the efficacy of intensive electro-acupuncture or manual acupuncture versus sham acupuncture in reducing pain and improving function in patients with KOA.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Electro-acupuncture | Experimental | 5 compulsory acupoints (ST35、EX-LE5、LR8、GB33 and Ashi) and 3 optional matching acupoints (stomach meridian syndrome：ST34、ST36、ST32、ST40、EX-LE2；gallbladder meridian syndrome：GB31、GB36、GB34、GB39、GB41；bladder meridian syndrome：BL39、BL40、BL57、BL60；San Yin meridian syndrome：LR7、SP9、SP10、KI10、SP4、SP6、LR3、KI3) will be chosen. Needles will be stimulated manually to achieve "De Qi" sensation and an electrical apparatus (Nanjing Jisheng Medical Co., Ltd., wave of 2/100Hz) will be then connected to the needles with alligator clips in pairs LR8-GB33 and two other matching acupoints. The stimulus intensity will be increased until the patient reports a strong but comfortable intensity. Patients will receive 30-minute, 24 sessions intervention over eight weeks. |
|
| manual acupuncture | Experimental | Participants in the manual acupuncture group have the same schedule as the Electro-acupuncture group except that the electrical apparatus has working power indicator and sound without actual current output. |
|
| sham acupuncture | Sham Comparator | Those in the sham acupuncture group receive shallow acupuncture at non-acupoints without manipulation，Deqi or actual current output. |

| Measure | Description | Time Frame |
|---|---|---|
| Response rate | the percentage of patients with improvement in average pain (numerical rating scale, NRS) at least 2 units and in Western Ontario and Mcmaster Universities Osteoarthritis Index (WOMAC) function subscale score at least 6 units at 8 weeks. Pain NRS was a self-administered instrument, a number selected from 0-10 by participant. Intensity of pain range (over past week): 0 =no pain to 10 =worst possible pain. Higher score indicating severe pain. The WOMAC function subscale referred to the participant's ability to move around and perform usual activities of daily living. The WOMAC function subscale was comprised of 17 questions regarding the degree of difficulty experienced due to OA in the study knee. The WOMAC function subscale score for each question ranged from 0 (minimum) to 4 (maximum), higher scores signified worse physical function. An overall score range of 0 (minimum) to 68 (maximum), with higher scores indicating worse physical function. | 8 weeks |
