Abstract: Acupotome therapy exhibits good efficacy on knee osteoarthritis in clinic. The mechanism based on its dynamic equilibrium theory is that acupotome therapy can restore normal joint stress state by changing the imbalance of mechanical equilibrium around the joint. Furthermore, it can ease inflammation, relieve pain and repair tissue structure so as to achieve its therapeutic effect. This review proposes new thoughts for the etiopathogenisis, pathology and treatment of KOA.

Key words: knee osteoarthritis, acupotome therapy, mechanism, dynamic equilibrium
