Meniscal cartilage regeneration is less likely and should be standardized in time to improve prognosis. Meniscus is a kind of fibrous cartilage, tooth-shaped, located inside the knee joint. Chronic grinding and violence are the main causes of meniscus injury. Since most of the area of meniscus has almost no blood supply and its nutrition mainly comes from bursal fluid, it is difficult to regenerate when there is an injury to the meniscus, but there is a certain chance that a laceration in the red-red zone of the meniscus will heal. It is recommended to pay attention to protect the knee joint in daily life, avoid long time squatting work and other violent activities, such as the shooting action of soccer, etc. Once the injury occurs, timely braking should be done, and you should go to the hospital for treatment under the guidance of the doctor.
