Why is the knee prone to degeneration? The knee joint is the largest and most complex joint in the human body, its main function is weight-bearing, its movement is mainly flexion, extension, and in the semi-flexion position, it can also do a small range of rotation inward and outward movement. Its position in the human body is shallow, in doing all kinds of activities to bear the degree of weight is the largest, the joint is very easy to instability, causing injury. Basically, it is one of the most commonly used joints in the human body for any activity such as walking, running, sitting, squatting, going up and down stairs, etc. It is also one of the most commonly used joints in the human body. Every day busy, hard work, of course, it is easy to wear and tear, damage, aging, degenerative changes is not difficult to understand. Is “osteomalacia”, “osteoarthritis” and “degeneration” of the knee joint the same thing? In daily life, people are often easy to be these three terms high omega, so in the end these three are the same thing? In fact, osteoarthritis is medically called “osteomalacia” and is an age-related degenerative disease of the joints. As people age, all organs of the body will age, this is a natural law, in which the natural wear and tear of the bones and joints is particularly strong. This natural wear and tear of the bones and joints due to aging is called “degeneration” or “osteoarthritis” in medical terms. It manifests itself in the destruction of joint surfaces and bone growth around the joints, which can be seen on X-ray: there are “thorns” growing on the bones around the joints. This is what people often call “bone spurs”, in fact, its nature is osteophytes, and the medical science is called “bone joint degeneration”, also called “osteophytes”. After all this, it turns out that these three terms are the same thing. When the knee joint is affected, it is called “degenerative osteoarthropathy of the knee”. What symptoms should be highly suspicious of knee degeneration? 1. Pain. Knee joint pain at the beginning of intermittent episodes, and then become a constant pain, in the work of the pain will be aggravated after exertion, especially up and down the stairs, the pain will feel more obvious. 2.Activity limitation. Some activities in the conduct of the pain will feel obvious, so that can not be completely done, such as running, jumping, kneeling, squatting, and even walking will appear limp. 3. Joint popping and friction sounds. There may be popping and friction sounds when the joints are moving, and some patients may even have swelling and fluid accumulation in the joints. Pressure and pain near the knee joint. Pain may be felt near the joint when doing activities. Who is prone to knee degeneration? 1, obese people: obesity will aggravate the wear and tear of the knee joint aging, osteoarthritis in the overweight people in the incidence of significantly higher than the normal population, and the age of onset is easy to advance. 2, women: especially after menopause women, due to the reduction of endogenous estrogen, osteoarthritis incidence increases, the degree is also heavier. 3.Patients who have a history of knee injury and have not been treated in time: such as joint instability caused by ligament injury around the joint, meniscus injury or intra-articular fracture. 4, some special occupational groups: such as miners, cotton pickers, heavy laborers, teachers, salespeople, professional athletes or dancers, etc., mainly due to long-term wear and tear of the joint cartilage by high-intensity stress or injury. 5, behavioral habits, such as artificial changes in the biomechanical environment of the joints can trigger osteoarthritis: such as wearing high-heeled shoes, walking, increased the usual stress on the knee joints, changing the balance of the knee joints, accelerating the degenerative changes in the knee joints. 6, long years of climbing stairs, climbing, mountaineering, easy to induce osteoarthritis of the knee joint. 7, the influence of genetic factors, congenital joint structural abnormalities and defects, cartilage or bone metabolism abnormalities, and genetic factors related to obesity and osteoporosis will cause osteoarthritis. What kind of exercise is suitable for patients with knee degeneration? What kind of exercise is not suitable? What details should I pay attention to in my life? Degenerative arthritis patients should try to reduce the burden on the knees when doing exercise, so it is not suitable for strenuous exercise, you can choose exercise with low intensity, such as walking, cycling, swimming, yoga, etc. Especially swimming, the buoyancy of water is very important. Especially swimming, the buoyancy of water can reduce the gravity of the joints, the most suitable for patients with degenerative knee osteoarthritis. Degenerative knee osteoarthritis patients are not suitable for deep squatting, hiking, basketball, soccer, jumping rope and other sports, usually to avoid long squatting, sitting, standing, frequent climbing, climbing stairs, deliberately and frequently exercise the knee joints. In daily life, do not sit on low stools and sofas if you can sit on high stools, and do not squat on clay toilets if you can defecate on a bidet. Pay attention to keeping the knee joint warm (whether in summer, fall, or winter and spring), wear knee pads, etc. How is degenerative knee disease treated? Since this disease is an irresistible process of natural aging of the human body, it cannot be cured at all. Treatment focuses on reducing symptoms and slowing down the progression. In the early stage, you should reduce the heavy load on the knee joints such as going up and down slopes, up and down stairs, squatting and so on. Conservative treatment: including physical therapy, drugs, injection therapy and traditional Chinese medicine, etc. Specifically: (1) Traditional Chinese medicine that promotes bone hardening and slows down osteophytes, such as “Xianling Bone Bo, anti-bone proliferation pills”, etc.; (2) Joint cartilage protection agents such as glucosamine drugs (hydrochloric acid and sulfuric acid are available); (3) Calcium, calcium, and other drugs. (2) Joint cartilage protection drugs such as glucosamine (hydrochloric acid and sulfuric acid are acceptable); (3) Calcium. (4) Intra-articular injection of sodium vitrate, which has the function of lubrication and protection of cartilage; (5) Non-steroidal anti-inflammatory and analgesic drugs: such as diclofenac sodium enteric-coated tablets, loxoprofen capsules, etc. When the joints are swollen with a lot of fluid, it is necessary to draw the fluid and fix it with an elastic bandage if necessary. (6) Physiotherapy (such as infrared rays, etc.), hot compresses, external plasters, such as “pain relief plaster”, Thousand Mountains blood cream, etc., have the effect of improving local blood circulation and alleviating symptoms. Surgery: In the end stage, the bone and articular cartilage of the joints will be seriously worn out and destroyed, and then the patient will have long-term pain and deformation of the knee joint, so it is necessary to consider surgical treatment (e.g. artificial knee replacement).
