It is possible to restore the meniscus to its previous state with meniscus surgery. The meniscus is usually able to maintain normal function after surgical repair, but if there is a poor surgical prognosis, a secondary injury, or if the meniscus is particularly badly damaged, etc., the recovery of the meniscus will be affected. For meniscus injuries, the vast majority of surgical treatments are able to maintain normal function of the meniscus. Through active rehabilitation training, strengthening the quadriceps muscle and knee joint will achieve better therapeutic effect. If the knee joint is immobilized for a long time after surgery and lacks rehabilitation training, it may cause stiffness and limited movement of the joint. If the knee joint is overloaded or improperly moved during the recovery process, it may cause secondary injury, all of which are not conducive to the recovery of the meniscus after surgery. In some cases where the meniscus damage is particularly severe, it may also be difficult to return to the previous normal state. For patients with meniscus injuries, it is recommended to seek timely medical treatment, adopt standardized treatment, actively carry out rehabilitation training and follow up on time, which will help the recovery after meniscus surgery.
