Brief Summary:

This is a two-armed randomised controlled pilot study that investigates the component efficacy of moxibustion for osteoarthritis of the knee. Participants will be randomised to receive either warm needle acupuncture or needle acupuncture. Participants and acupuncturists will be blinded to group allocation. The primary and secondary outcome measures are WOMAC and SF36 respectively. Qualitative interviews will be used to gather information on the patients' experiences and perceptions of the trial and the treatment provided.

It is hypothesised that warm needle acupuncture will lead to a greater reduction in clinical signs and symptoms than needle acupuncture.


Condition or disease Intervention/treatment Phase
Osteoarthritis, Knee Device: Warm needle acupuncture Device: Needle acupuncture Not Applicable

Detailed Description:

Acupuncture Treatment

All participants will receive acupuncture. Only points local to the knee will be used. There will be 4-6 points used per knee, therefore 8 -12 needles per treatment. A record will be kept of the points used at each treatment. Both knees will be treated even if only one knee is painful. This will ensure that participants receive similar treatments.

Patients will be treated seated, as this allows better access to the relevant acupuncture points. It also helps ensure the moxibustion is carried out safely.

Participants will receive 8 treatments in the first 4 weeks (twice a week), then 4 treatments in 4 weeks (once a week).

Blinding procedures

The only difference in the procedures will be that lit cones are placed on the needles of the treatment group whilst unlit moxa cones will be placed on the needles of the control group. Smokeless moxa will be used. All patients will see the needles being inserted and the moxa cones placed on the needles by the acupuncturist. Skin guards will be placed at the base of the needle to reduce the immediate sense of heat on the surface of the skin. Similar skin guards are routinely used in acupuncture treatment to prevent any discomfort.

The acupuncturist will carry out a consultation at each session as per normal practice. After the needles have been inserted and the moxa cones have been placed on needles the acupuncturist leaves and an assistant acupuncturist enters the room. The assistant acupuncturist will place a screen in front of the patient to prevent them from seeing their knees. The assistant acupuncturist will then remove one cone at a time and light it. In the treatment group the lit cone is placed on the needle. In the control group the lit cone is place in a small dish close to the knee, a replacement unlit cone is placed on the needle. This process is repeated until all the cones are lit. The unlit cone is replaced on the needle of the control group to try and ensure they experience the same sensations as the treatment group. The use of a second acupuncturist to light the moxa ensures that the acupuncturist who carries out the consultation and inserts the needles is blinded to group allocation.

Arm Intervention/treatment
Experimental: Warm needle acupuncture

Warm needle acupuncture (wenzhen; 温针) is where moxa cones are placed on the handle of the needle, after the needle has been inserted. Once lit, heat transmits along the shaft of the needle to the acupuncture point.

Moxa refers to the herb mugwort (Artemisia vulgaris) that is burnt to warm specific parts of the body, including acupuncture points.

Device: Warm needle acupuncture
There will be 4-6 points used per knee, therefore 8-12 needles per treatment. Two points will be used as the core treatment ST 35 dubi, Ex-LE 5 xiyan. Four other acu-points can also be used from the following: Ahshi painful points local to the knee (locus dolendi), ST 36 zusanli, GB 34 yanglingquan, Sp 9 yinlingquan, ST34 liangqiu, Sp 10 xuehai, GB 33 yangxiguan, LR 7 xiguan, LR 8 ququan, heding Ex-LE 2 In addition to the acupuncture needles the warm needle acupuncture group will receive moxibustion on up to 4 points. Smokeless moxa will be used.

Active Comparator: Basic needle acupuncture
Basic needle acupuncture is the use of acupuncture needles alone, without other methods of stimulation.
Device: Needle acupuncture
The point selection protocol will be exactly the same as the experimental group
