After the meniscus is cured, most of the ordinary patients can be the same as normal people, a few patients with more serious injuries may be left with joint dysfunction. 1. Ordinary patients: Meniscus is simply the “cushion” between the tibial plateau and the femur, which mainly serves to cushion the joint pressure. In addition to a small number of patients with marginal injuries can be repaired on their own, most patients need to undergo surgical treatment, such as arthroscopic clean-up surgery, meniscus suture surgery, etc. After comprehensive treatment, most patients can be the same as normal people. 2. Serious patients: a small number of traumatic causes of meniscus completely torn patients, due to the inability to meniscus suture or repair, can only be in the arthroscopic reconstruction of the meniscus. Even if the surgery is successful and the anatomical structure is rebuilt, it is very difficult to recover to the normal level through a lot of rehabilitation training and other treatments in the later stage, and most of them will be left with sequelae such as joint obstacles and early aging of the joints.
