[Exploration on acupuncture treatment ideas for knee osteoarthritis from the perspective of Dongyuan needling technology].

The treatment ideas with acupuncture for knee osteoarthritis (KOA) are explored on the base of Dongyuan needling technology. Regarding the rules of acupoint selection, Zusanli (ST 36) is predominant, the back-shu points are used for the disorders related to the invasion of exogenous factors, and the front-mu points are for the cases caused by internal injury. Besides, the xing-spring points and shu-stream points are preferred. In treatment of KOA, besides the local points, the front-mu points, i.e. Zhongwan (CV 12), Tianshu (ST 25) and Guanyuan (CV 4), are selected specially to tonifying the spleen and stomach. The earth points and acupoints on the earth meridians (i.e. Yinlingquan [SP 9], Xuehai [SP 10], Liangqiu [ST 34], Dubi [ST 35], Zusanli [ST 36] and Yanglingquan [GB 34]) are optional to coordinate yin and yang, essence and qi , and regulate the qi movement of spleen and stomach. The shu-stream points of liver, spleen and kidney meridians (Taichong [LR 3], Taibai [SP 3] and Taixi [KI 3]) are chosen to promote meridian circulation and regulate zangfu functions.
