For knee pain, acupuncture often focuses on local selection of acupoints, often using points around the knee joint, including internal and external knee eyes, blood sea, liangqiu, hedge, sesanli, san yinjiao, yanglingquan, and yinlingquan. If the pain is medial, the three yin meridians may predominate, and acupoints such as Tai Xi, San Yin Jiao, and Tai Chong may be chosen. If the pain is predominantly lateral, you may choose points of the lateral Shaoyang Bile meridian, such as Hanging Bell and Foot Lin Weeping. For posterior lateral pain, acupuncture points of the foot and sun bladder meridians may be used, such as the Wei Zhong point, Kun Lun, and Cheng Shan point. Therefore, different acupoints are often used for different parts of the body for pain. For patients with knee pain, it also needs to be combined with the patient’s status, and in the case of obese patients, moderate weight loss is required, such as abdominal acupoints would be added or subtracted for use. In older patients with physical decline, Kidney Yu and Guan Yuan may be added to cultivate Yang energy. In patients with knee pain, it is also important to perform the necessary physical and objective examinations, including X-rays and MRI, which can clarify the severity of the lesion. In the case of patients with knee pain, osteoarthritis of the knee can cause pain. In addition, meniscal injury, anterior and posterior cruciate ligament injury, medial and lateral collateral ligament injury, or joint effusion can cause pain, and treatment may vary depending on the cause of the pathology.
