Patellofemoral pain syndrome(PFPS)is one of the main diseases leading to patellofemoral joint dysfunction,which seriously affects the quality of life of patients.This disease is classified as"knee impediment"and"tendon impediment"in TCM,and acupuncture treatment has a significant effect on this disease.This article combed the clinical studies on acupuncture treatment of PFPS in recent years around filiform needling,warm acupuncture and moxibustion,fire needle,needle knife,electro-acupuncture and other acupuncture treatments,and discussed the clinical effects and application scope of different treatments.Studies have shown that acupuncture therapy can effectively improve the symptoms and function of PFPS through a variety of mechanisms,such as regulating the function of the central nervous system,promoting the absorption of inflammatory factors and the clearance of joint effusion,and improving local blood circulation.These findings provide an important reference for the clinical treatment of PFPS.
