Suggestion: Hello, surgical treatment is not recommended for meniscus injury. Surgery is a method of western medicine to treat soft tissue injury. If there is something wrong with the meniscus, it should be removed. Should the nose ache be cut off? Meniscus is the protection of knee joint movement up and down. When the meniscus is cut off, the human knee loses a kind of protection. Since the protection of these knee joints has been artificially destroyed, it is impossible to restore the original state. For the problem of hydrops, this is caused by soft tissue injury. After soft tissue injury, human body fluids and a small amount of blood will slowly ooze out and form swelling. Western medicine examination is called effusion, and simply pumping liquid with a syringe can't solve the problem. Suction only plays a temporary role, not a permanent cure, because the soft tissue has not been repaired and healed, and these hydrops will slowly seep out. Only when the soft tissue is completely repaired will these hydrops be eliminated. Generally, the treatment of this condition is mainly conservative treatment, and the clinical cure can be achieved through oral and external drugs, physical therapy and scientific rehabilitation exercise. The cost of treatment mainly refers to the treatment method and the degree of illness. I wish your child a speedy recovery.
