When a meniscus injury occurs, the knee should be immobilized immediately to prevent the knee from moving and aggravating the injury, and an ice pack or cold water should be applied to the knee immediately. If the meniscus is severely damaged, the pain is severe, and the knee joint is immobile, and manipulation is ineffective, surgery is required to remove the free meniscus or repair it immediately after the knee joint is free of swelling. If the injury is not serious, you can apply manual massage to avoid the injury site and perform manual swelling reduction treatment, and if there are symptoms of joint locking, you can perform manual reset.
