The latest treatment concepts of meniscus injury Although meniscus injury is a common disease, but we must not ignore its timely and correct treatment, otherwise we will lose the best time for treatment, resulting in doctors and patients do not want to see the adverse results. As far as I know, the concepts of meniscus injury treatment in China and Germany, the most important common points are: 1) The earlier the treatment, the better 2) Suture if you can 3) If you can’t, keep as much as possible 4) Leave a little bit of it if you can 5) Seek professional doctor’s consultation as soon as possible, neither should you think it is too troublesome not to consult the doctor nor should you find a doctor casually In addition, meniscal transplantation is not yet a common treatment in the international community. In addition, meniscus transplantation is not yet a routine treatment in the international arena, and has its own strict indications and contraindications. During my stay in Heidelberg, I attended 2-3 meniscus transplants per month on average. However, the results are not yet satisfactory for everyone. I think the most important thing is to use this technique wisely and responsibly and not to cause unnecessary problems for the patient! Here are a few brief facts about meniscus injuries. Here I would like to remind you one thing: it is very important for a patient to understand the relevant medical knowledge! First, anatomical structure 1, the medial meniscus (MM) spacing between the two ends is large, was “C” type, the edge of the joint capsule and the medial collateral ligament is connected to the deep layer. The lateral meniscus (LM) is “O” shaped, with the N tendon separating the meniscus from the joint capsule in the middle and posterior 1/3 to form a gap, and the lateral meniscus is separated from the lateral collateral ligament. Second, blood supply: 1, there is blood supply at the anterior and posterior horn attachment, and at the rim where it is attached to the joint capsule (the area with blackened staining) 2, there is no blood supply in the central 2/3, and the nutrition comes from the joint fluid. Therefore, once this part is injured, it is not suitable for suture because it is difficult to heal without sufficient blood supply III. Mechanical and histological structure: 1, meniscus is a semilunar fibrocartilaginous disk with triangular section 2, concave on the top and flat on the bottom 3, the surface is covered with a thin layer of fibrocartilage, and the inner part is a dense collagen fiber mixed with a large number of elastic fibers 4, the restraining effect of peripheral fibers (the role of the barrel hoop)
