Knee massage involves gentle warming strokes, effleurage (gliding), petrissage (kneading), and friction techniques, focusing on surrounding muscles (quads, hamstrings, calves) and avoiding direct pressure on the kneecap (patella) to relieve pain, improve flexibility, and increase blood flow, often using oils or creams for smoother application. Techniques include circular motions around the knee, working the fascia, and releasing tightness in the quads and hamstrings, but always consult a doctor first and stop if you feel pain.
