Injuries to the anterior and posterior meniscus of the knee need to be treated conservatively or surgically, and when the anterior and posterior meniscus of the knee are 1-2 degrees, strictly conservative treatment can be done first. For a month or so, the joint should be completely immobilized to avoid stress on the joint, and the knee should be treated with blood circulation and microwave physiotherapy. If necessary, intra-articular injections of sodium vitreous acid can be given to promote the recovery of the meniscus. For 3rd degree damage or even tears of the anterior and posterior meniscus of the knee, the main treatment method is surgery, which involves arthroscopic repair, trimming or even removal of the meniscus.
