Patients with straight calves may have inversion or valgus of the knee, which can be treated conservatively if they want to straighten their calves. Traditional Chinese medicine techniques are used for local massage and correction. This is because through massage, the blood circulation of the local muscles can be stimulated, the metabolism within the muscles can be stimulated, and the degree of local muscle adhesions can be relieved or improved. After massage and correction, orthopedic braces are also needed for fixation. If the condition is present in adults, surgical treatment may be considered after conservative treatment has failed. The incision and correction can be performed under epidural anesthesia, and postoperative fixation with an orthopedic brace is also required. In addition, the patient should be instructed to perform early functional knee exercises to prevent the development of knee stiffness, etc.
