Meniscal tears are usually difficult to heal on their own, specifically because they are the most serious degree of meniscus injury and require surgical suturing, and cannot heal on their own. The meniscus should be diagnosed and treated promptly after a meniscus tear occurs in order to fully restore the function of the meniscus. If treatment is delayed, it will make it difficult to suture the meniscus tear site and only meniscus revision surgery can be performed to remove part of the meniscus tissue, which will destroy the normal function of the meniscus and make the joint degeneration speed up significantly, which will cause degenerative osteoarthritis of the joint and make the patient have clinical symptoms such as joint pain and restricted movement.
