People often say: “People get old before their legs get old”. With the continuous improvement of the living standard of the general public, China’s population aging and other social problems are becoming increasingly serious. At present, China is in the stage of rapid growth of aging society. According to statistics, as of December 31, 2008, China’s elderly population of over 60 years old is 159 million, ranking first in the world. Henan is a province with a large population, and there is 1 elderly person in every 10 people. nearly 10 million people over 60 years old. A research institute, a study of 110 normal people without knee symptoms showed that the X-ray detection rate of osteoarthritis of the knee was 18%, 38%, 57%, and 61% for ages <30, 31-40, 41-50, and 51-64, respectively. There is a trend of gradual increase with increasing age. This study suggests that osteoarthritis of the knee may have started in youth. That is, it suggests that osteoarthritis of the knee is initiated in youth, develops in middle age, and develops in old age. Because of the high clinical incidence of osteoarthritis, especially osteoarthritis of the knee joint is the most prevalent. Therefore, the World Health Organization has designated the period 2000-2010 as the "Bone and Joint Decade". In this way, it has drawn the attention of the world. China has also defined 2002-2012 as the "Bone and Joint Decade" in China, i.e. "China Bone and Joint Decade". The action plan and goals have been set. Modern medicine believes that the occurrence of this disease is related to obesity, overuse of the knee joint, injury, developmental abnormalities, genetic susceptibility and weakness of the quadriceps muscle, in addition to age factors. In Chinese medicine, osteoarthritis of the knee joint is classified as "bone paralysis". It is believed that the cause of this disease is due to the lack of positive energy and the invasion of external evil. Therefore, we often encounter this situation in our life, every time the weather becomes cold, the knee joint will be cold or slightly strained, and then the joint will become sore or painful. The onset of osteoarthritis of the knee joint does not occur in a short period of time. Rather, it develops gradually over time as a result of long-term strain and injury. Therefore, the effect of treatment is slow. In the early stages of osteoarthritis of the knee, the main symptom is localized pain or soreness in the knee joint after cold or strain, which can sometimes be recovered with rest or heat. However, after several repeated episodes, the degree of joint damage increases, and it is usually difficult to recover after rest. This is when proper treatment and maintenance are required. The easiest way is to use a hot water bag to temporarily relieve or reduce the pain, but if it does not completely relieve the pain, go to a hospital orthopedic clinic. Your physician will advise you on proper maintenance, exercises and precautions as well as give you the correct treatment. Because osteoarthritis of the knee joint is slow to develop and has a long course, attacks are more painful. Chinese medicine has the principle of "treating the symptoms when it is urgent, and treating the root cause when it is slow", so this disease is very suitable for Chinese herbal treatment. Currently, the goal of domestic and foreign medical experts in treating osteoarthritis of the knee is to relieve or relieve the pain and swelling of the knee joint, and to slow down the onset and development of knee joint damage and degeneration. If medications do not work, surgery is the only treatment. The treatment used varies with the extent of the lesion and the results vary greatly. How do I choose the right treatment? The treatment of this disease varies according to the severity of the patient's symptoms. Activities such as squatting, climbing and going up and down stairs can trigger and aggravate the disease. For mild cases, topical medication and physical therapy are preferred to relieve symptoms (such as infrared irradiation or hot water bags for local heat application). If there is joint swelling and fluid accumulation, acetaminophen is not effective and non-steroidal anti-inflammatory drugs should be used or the patient should go to the hospital for treatment. For patients with joint swelling and fluid accumulation, joint puncture and fluid closure is effective, but the hormones in the closure drugs are not good for joint cartilage and should not be used repeatedly. Intra-articular injection of sodium hyaluronate is a new treatment carried out in recent years, sodium hyaluronate plays the role of lubricating the joint and nourishing the cartilage, the same oral glucosamine and chondroitin also have the role of nutrition and promote cartilage repair, the efficacy varies from person to person, and the effect is not good in patients with severe joint deformation. Individual patients who experience frequent stumbling in the knee joint when walking are usually suffering from meniscal damage or bone fragmentation in the joint cavity, which requires arthroscopic treatment. Arthroscopy is a minimally invasive surgical technique that cleans up worn bone fragments and free bodies in the joint, repairs broken and ruptured meniscus, smoothes worn cartilage, removes hyperplastic synovial membranes, and removes bone spurs. In addition, osteotomy is an orthopedic surgery for younger patients with joint deformation, which can change the force line of lower limbs, relieve symptoms and postpone joint replacement. For some patients with severe joint deformation and unbearable pain that affects normal life, if there are no contraindications to surgery, long-term conservative treatment is ineffective. It is best to have an artificial knee replacement. Artificial knee replacement is an effective treatment for patients with severe pain and severe joint dysfunction, which can significantly relieve pain, maintain joint movement and improve quality of life. Full recovery after surgery usually takes three months. The artificial knee joint is designed on the basis of extremely advanced metallurgy, biomaterials, biomechanics and orthopedic surgery. The world is now able to produce artificial knee joints that are close to their physiological form and can replace the original human knee joint. The principle of Chinese medicine in treating diseases is: "treat early if there is a disease, prevent first if there is no disease, prevention is better than cure". Therefore, please keep in mind for those who suffer from osteoarthritis of the knee joint or those who do not yet suffer from arthritis that to protect your knee joint, you must adhere to: "three ones". That is: drink a bag of milk or a bowl of soy milk every day; get an hour of sunshine; and do an hour of proper exercise. Do not let your knee joints be attacked by cold or injured by strain. If you can do it, you will receive unexpected results.
