Osteoarthritis, also known as osteoarthrosis, proliferative arthritis, and degenerative arthritis, is also known as senile arthritis because it occurs in the elderly. The pathogenesis of osteoarthritis is the result of abnormal cartilage function, structural damage, contact of bone tissue with each other, joint deformation and abnormal function due to sports injury, joint overuse, developmental abnormalities, infection, metabolic disorders, endocrine abnormalities and other diseases. With the aging of the population, the number of patients with osteoarthritis is increasing. Unfortunately, many patients do not receive scientific treatment. So, what is the scientific treatment for this disease? Case 1: Patient Wang, female, 46 years old, had pain in her right knee for more than 2 months, which was sometimes mild and sometimes severe. X-ray: normal joint structure, mild osteophytes, no destruction of cartilage. The diagnosis was early osteoarthritis. He was given a combination of Chinese herbal medicine, heat penetration, and oral glucosamine hydrochloride capsule, and the symptoms disappeared after 3 weeks. Case 2: Patient Zhang, female, 65 years old, had pain and mild swelling in both knees for more than 5 years, took anti-inflammatory and pain-relieving western medicine for a long time, but the symptoms worsened again after stopping the medicine, X-ray radiograph: mild osteophytes in the knee joint, narrow internal and external width of the joint space, mild inversion of the knee. He was diagnosed with mid-stage osteoarthritis. He was given joint irrigation, O3 treatment, herbal heat penetration, oral antiosteogenic capsules and glucosamine hydrochloride capsules for 6 weeks and then his symptoms were basically relieved. Case 3: Patient Li, female, 72 years old, had pain in both knees for more than 15 years. She was unable to squat, had difficulty in starting, and woke up at night with pain, and could not be relieved by taking a lot of anti-inflammatory drugs for a long time. She sought treatment from our department and was given an artificial total knee replacement surgery. She exercised her knee on the third day after the surgery, had her stitches removed 2 weeks later, stood with the help of crutches, and walked with the help of crutches 4 weeks later. The patient said that I was most satisfied that he could squat and go to the toilet, and that he could go to the park for exercise like other elderly people. Case 4: Patient Wang, female, 73 years old, with severe inversion of both knees like O-shape, painful all day long, taking pain medication ineffective, history of more than 15 years. She was diagnosed with late-stage osteoarthritis. Three years ago, her doctor recommended artificial joint replacement surgery, but she refused the surgery and requested conservative treatment. Because he could not get enough activities, his body soon gained weight, followed by high blood pressure, hypertension, heart disease and diabetes, and the doctor no longer dared to mention the word surgery for him. It is a pity. The first three patients mentioned above, who suffered from the same disease, were treated with reasonable treatment methods for different degrees of severity and all had a better prognosis. Case 4 listed a patient with arthritis at an advanced stage and complete loss of function, who lost the best time for treatment because he was backward and could not accept the doctor’s advice. Although the disease did not appear to be a fatal visceral disease, it seriously affected the function of the internal organs and ultimately shortened his life. Therefore, reasonable staging of this disease is crucial! While it is not good to operate ahead of time without surgical indications, it is even more undesirable to blindly refuse surgery when the joint function is already ruined. Older people whose internal organs can still tolerate surgery should change their mindset and undergo scientific surgical treatment. Currently, medical science is developing rapidly and artificial joint technology is becoming more and more mature, which is widely used in the clinic for the benefit of patients. Finally, patients are reminded to develop reasonable preventive measures to prevent the development of the disease: 1, pay attention to warmth: to prevent feeling wind, cold and wet. Do not live in wet places for a long time. Especially in the young must not as long as the wind, but not temperature. Some older people like winter swimming, from the perspective of joint physiology is not appropriate. 2.Appropriate exercise: but not excessive use of joints. Some elderly people often climb hills because of the better function of internal organs and are proud of it, but they do not know that this exercise is not the best way for the elderly to exercise. Because climbing will accelerate the wear and tear of the joints. Of course, Taijiquan does not favor people with arthritis. 3, prevention of osteoporosis: the elderly love to eat vegetarian, although the prevention of hyperlipidemia hypertension heart disease obesity beneficial, but long-term vegetarianism, will aggravate the development of accelerated osteoporosis. Mild osteopenia is not a big deal, but premature osteoporosis is a very bad thing. A little bit of high quality protein every day will be beneficial to the bones and joints. 4, to learn to refuse pain medication and hormone therapy: such drugs for momentary relief of symptoms, although they have some effect, but the long-term use of the results will only aggravate the degeneration of the joints!
