Can knee meniscus heal itself?

The meniscus of knee joint is divided into red zone, red and white junction zone and white zone according to different blood supply. The red zone has the best blood supply and rich blood vessels, while the white zone has almost no blood supply. The red and white junctional blood supply is between the two tears. If it occurs in the position of poor blood supply, the less likely the tear is to heal. Partial meniscus bone contusion and incomplete tear, in the case of full braking in the acute phase, there is a certain healing ability. Therefore, in the case of acute injury, be sure to do a good job of knee joint braking, do not exercise in the case of acute injury
