A knee brace for continual electro-acupuncture stimulation system comprises a first circuit having a first circuit having a first electrode configured to electrically coupled to acupuncture point “Heting (S 156)” and a second electrode configured to electrically coupled to acupuncture point “Bladder 40”, a second circuit having a third electrode configured to electrically coupled to acupuncture point “Spleen 10” and a fourth electrode configured to electrically coupled to acupuncture point “Hsiyen (S 145)”, and a third circuit having a fifth electrode configured to electrically coupled to acupuncture point “Stomach 34” and a sixth electrode configured to electrically coupled to acupuncture point “Stomach 35”. The first, third, and fifth electrodes are connected to a polarity of voltage, and the second, fourth, and sixth electrodes are connected to an opposite polarity of voltage, such that electric currents flow in a body of a patient to achieve analgesia, cartilage repair and regeneration in the knee joint.
