If the injury is of degree I or II, it can be treated by rest and braking, physical therapy and medication; if the injury reaches degree III and there is a complete tear, it can be treated by surgery. 1. Rest and braking: If the injury is I or II degree and the symptoms are mild, rest should be paid attention to, avoid weight bearing on the affected limb, reduce the crushing of meniscus, and prevent further aggravation of the injury. If necessary, plaster can be used for external fixation. 2. Physiotherapy: Physiotherapy methods, such as microwave, ultrashort wave, etc., can be used, which is helpful for anti-inflammatory and pain relief and symptomatic relief. 3.
