There is no best way to treat a meniscus tear in the knee, which can be treated by plaster immobilization or surgery, depending on the severity of the tear. 1. Mild tear: If the patient’s meniscus tear is mild and without obvious symptoms, it can be treated conservatively, usually through plaster immobilization after icing to alleviate the symptoms. If the patient has blood accumulation in the knee joint, pressure bandage can be applied. 2. Heavy tear: If the patient has a heavy meniscus tear, serious swelling and pain, or interlocking, it can be treated by surgery. If the blood supply in the red part of the meniscus is good, it can be repaired by suture; if the blood supply in the white part of the meniscus is not good, it can be treated by partially removing the meniscus. Patients diagnosed with meniscus tear need to go to the hospital for examination and diagnosis to determine whether the tear is serious or not, and then get the appropriate treatment plan. There is no best treatment option for different patients.
