ACU_Knee: Role of Acupuncture in Knee Prosthetic Surgery

In the Acu group, acupuncture and auriculotherapy will be added to the standard treatment: patients will undergo three/four sessions of manual acupuncture lasting 20 minutes, the first in the immediate pre-operative period and the subsequent ones at a distance of 24, 48, 72 hours from surgery. The treatment includes manual acupuncture applied to specific points: LI4, LV3 and ST36 bilaterally and monolaterally SP6 and GB34, ipsilateral to the knee to be prostheticized. Furthermore, auricolar needles will be positioned, before surgery, for self-stimulation of the auriculotherapy points corresponding to Shen Men bilaterally and the knee point ipsilateral to the surgical side.
