Generally speaking, 40 meniscus degeneration is normal and mild degeneration is not serious enough to warrant special treatment. As the meniscus ages, the rate of degeneration gradually increases; around 30 years of age, the rate of degeneration begins to accelerate, and around 50 years of age, significant degeneration occurs. In general, mild meniscal degeneration is not serious, but it is important to keep exercising to improve the strength of the muscles around the knee and the stability of the joint. If the meniscus degenerates to a greater extent, there is a risk of meniscus injury. As they age, middle-aged and older adults should avoid excessive weight-bearing activities such as hiking and walking up and down stairs to prevent meniscal degeneration from worsening. If meniscal degeneration occurs, weight control should be practiced, and daily exercise should be maintained to avoid strenuous exercise. If the degree of degeneration is increasing, you should go to the hospital in time, under the guidance of the doctor for treatment.
