The position of the medial plica of the joint cavity "Save yourself with your knees" on page 48.

After millions of years of evolution, the structure of human knee joint is exquisite and perfect. Theoretically, cartilage is not easy to be injured or "degenerated". Unless the structure is damaged (such as meniscus cartilage, cruciate ligament damage or even fracture caused by excessive strenuous exercise), the stability of the knee joint will be affected and the cartilage will be gradually damaged. This is called "traumatic osteoarthritis" in medicine, accounting for about 10% of patients with "degenerative knee arthritis". But most people have never been injured (accounting for 90% of patients with "degenerative" knee arthritis). Why do their knees "degenerate"? If middle-aged (over 40 years old) patients with knee pain see a doctor, they will almost always be diagnosed as "degenerative" knee arthritis, because X-ray examination will always see more or less cartilage destruction. At present, the standard treatment suggestions for patients with "degenerative" knee arthritis by doctors who have received orthodox training all over the world are: rehabilitation, taking anti-inflammatory painkillers, supplementing cartilage components (glucosamine) and injecting lubricating protective agent (hyaluronic acid). If it fails, it is recommended to inject concentrated platelets (PRP). Finally, we had to replace the artificial joint. Such a traditional course of treatment can't fundamentally cure "degenerative" knee arthritis, but it gives a lot of space for various alternative therapies, and it costs less, so delaying the illness will not pay off. According to the author's long-term observation and research in recent ten years, the real cause of pain in 90% patients is not "degeneration", but mostly "medial friction syndrome" caused by friction between medial folds and joints. Medial plica is a plica that remains in the synovial cavity of the knee joint during embryonic development. It looks like a pile of clothes. Normal people's knees bend up to one million times a year on average. Every time the knee joint flexes and stretches, the medial plica of the joint and the femoral condyle will rub against each other, resulting in physical and chemical damage. With the increase of age, the medial plica rubs against the femoral condyle for tens of millions of times. If you are engaged in it, therefore, the internal folds are as soft as fresh loofah, and after years of friction, they will eventually become as rough as cabbage cloth. When people are young, the inner folds are smooth and thin and translucent; In their thirties and forties, the medial plica began to fibrosis, gradually losing its elasticity and hardening; Wear and inflammation occur after 50 years old, and articular cartilage damage increases year by year. Medial plica will affect the activity of knee joint for life, and it will also cause different degrees of "degeneration" of knee joint because of different daily activities and working conditions of everyone. When the medial plica is inflamed, thickened and inelastic, it will wear the cartilage on the femoral surface. Inflammation caused by repeated attacks on medial plica itself will also release harmful chemicals, which will gradually disintegrate articular cartilage. Debris produced by cartilage wear or disintegration will fall into the joint, resulting in more abnormal friction, which will lead to accelerated destruction of cartilage and continue to "degenerate" the knee joint. ▲ Physical wear: when the knee joint flexes and stretches, the medial plica rubs against the medial femoral condyle ▲ Chemical damage: Inflammation of the medial plica will release toxic chemicals to erode articular cartilage. Excerpt from this article: Your own knee saved a book. More: Degenerative knee arthritis in goo.gl/csXHmQ is not degenerative at all! Are you still drinking glucosamine? Still playing hyaluronic acid? Even expensive platelets? In fact, as long as a new concept, you can make your knees better and better! Attach a simple and easy-to-operate method to maintain the knee joint. Are you still using the wrong concept for the wrong treatment? Twelve misunderstandings about "degenerative knee arthritis": 1. Is a natural aging phenomenon, as long as you are old, it will inevitably happen. 2. Young people will not get degenerative knee arthritis. 3. Once the cartilage of knee joint is destroyed, it cannot be regenerated. 4. Once the knee joint degenerates, it will continue and cannot be stopped or reversed. 5. The incidence of female degenerative knee arthritis is high. 6. Degeneration of knee joint is related to osteoporosis. 7. Glucosamine and chondroitin can effectively control the degeneration of knee joint. 8. Injection of hyaluronic acid can effectively control knee joint degeneration. 9. Platelet concentrated preparation can effectively treat degenerative knee arthritis. 10. Artificial knee replacement is the best method to treat degenerative knee arthritis. 1 1. The smaller the trauma, the smaller the injury and the faster the recovery. 12. Artificial joints can only be used for ten years. Tell you, the above twelve misunderstandings are all wrong! A revolutionary new discovery: degenerative knee arthritis is not degenerative at all! As long as we grasp the golden period of treatment, it is not a dream to restore the health of the knee!
