If a patient has a meniscus injury, most of the treatment can be conservative, mainly resting, resting and reducing activities. The knee joint can be fixed with a brace or cast to maintain the stability of the knee joint and prevent the meniscus from being repeatedly stimulated by external forces. The painful area can be treated with blood circulation ointment and Bandon Tendon paste to promote local blood circulation, which can gradually relieve the meniscus injury. The patient should also be instructed to take chondroitin hydrochloride or glucosamine sulfate orally, which can improve the meniscus’ resistance to wear and tear. If the patient has severe pain, frequent kyphosis and locking, minimally invasive surgery can be performed using arthroscopy to repair the meniscus in the knee.
