Know the knee joint and protect the knee joint

The knee joint is the largest trochlear joint in the human body with the most complex structure and function.RONTEN Human Anatomy Knee Model A flexible life-size knee model that explains the knee joint. It is formed by the reinforcement of bone, articular cartilage, cruciate ligament in the joint cavity, meniscus, synovial fluid, joint capsule and extra-articular ligaments. The knee joint consists of the lateral femoral condyle and the lateral tibial condyle to form the lateral tibiofemoral joint, the medial tibial condyle and the medial tibial condyle form the medial tibiofemoral joint, and the patellar articular surface and the femoral trochlear form the patellar joint. It can be seen that the knee joint is composed of three joints. It is a complex large joint, and any major structural damage to the knee joint can affect its motor function.

How does knee joint degeneration happen? The normal knee surface has a thin layer of hyaline cartilage that is very resistant to friction, which is light blue, translucent, smooth and shiny. This layer of abrasion-resistant hyaline cartilage is very important in the motor function of the knee joint. The knee joint is the joint with the largest load and the most movement in the human body, so it is also the joint with the earliest degeneration and the most damage in the human body. Middle-aged and elderly people over the age of 45, especially women, due to the decline in hormone levels in their bodies, will cause the hyaline cartilage of the knee joint to degenerate and atrophy. Coupled with some minor injuries, the smooth, mirror-like hyaline cartilage will appear dotted. "rust spots", that is, local necrosis. At this point, the body will mobilize all kinds of internal forces to repair the "rust spot", including oozing more and more joint fluid and bone repair. However, the exuded synovial fluid is an acidic liquid, which is not only not conducive to the repair of "rust spots", but also forms a variety of chemical inflammatory mediators to stimulate, causing a series of symptoms such as swelling around the joints, pain, and difficulty in walking.

Knee degenerative disease, also known as osteoarthritis, osteoarthritis, degenerative joint disease, proliferative joint disease, hypertrophic arthritis, senile arthritis, etc., is the most common chronic and progressive joint disease. Its pathological characteristics are degeneration and destruction of articular cartilage, subchondral bone sclerosis, reactive hyperplasia of joint edge and subchondral bone, and formation of osteophytes. Its clinical manifestations include knee swelling, pain, difficulty walking, difficulty going up and downstairs, difficulty squatting while standing, unable to stand up while squatting, etc. Although the disease progresses slowly and every patient presents differently, the final outcome is the same—loss of walking in the knee.

Protecting the knee joint and prolonging the degeneration of the knee joint must be done daily, including paying attention to the posture of walking and labor, and not twisting the body to walk and work. Do not wear high-heeled shoes when walking long distances, try to walk on flat roads, avoid going up and down stairs, squatting, mountaineering and other activities to reduce the impact on the knee joint and avoid knee joint wear; try to avoid obesity and prevent aggravating the knee joint. Once you are overweight, you must actively lose weight and control your weight; in terms of diet, you should eat more foods containing protein, calcium, collagen, and isoflavones, such as milk, dairy products, soybeans, soy products, eggs, fish and shrimp. , kelp, black fungus, chicken feet, pig trotters, lamb legs, beef tendons, etc., these can not only supplement protein, calcium, prevent osteoporosis, but also grow cartilage and joint lubricating fluid, but also supplement estrogen, make The bones and joints can better metabolize calcium and reduce the symptoms of knee arthritis.
However, it should be noted that these preventions can only delay but not prevent the degeneration of the knee joint; when the disease develops more seriously, it is necessary to seek medical attention and follow the steps of treatment under the guidance of the doctor.
