The meniscus will degenerate as the body ages, with the rate of degeneration beginning to accelerate at about 30 years of age and becoming apparent at about 50 years of age, with degeneration of the posterior horn of the meniscus occurring more often after 50 years of age.
The meniscus is located in the articular space of the knee joint and can compensate for the discomfort between the condylar surface of the tibia and the condylar surface of the femur, increasing the stability of the joint. The cumulative use of the meniscus will cause the meniscus to suffer repeated extrusion, friction, will make the relatively intact, smooth meniscus surface edema and surrounding roughness, obvious degeneration, hyperplasia and calcification.
Therefore, with the aging, middle-aged and elderly people should pay attention to avoid excessive weight-bearing activities on the legs, avoid deep squatting, or avoid repeated up and down stairs, climbing and other activities, so as to minimize or delay the aggravation of the meniscus degeneration injury.
If the diagnosis of posterior meniscal degeneration is confirmed, it is recommended that standardized treatment be carried out as soon as possible in order to reduce the adverse effects of the disease.
