What exactly is osteoarthritis? Osteoarthritis of the knee is a disease caused by a variety of causes that compromise the integrity of the articular cartilage, the main lesions of which are degenerative changes in the articular cartilage and secondary osteophytes. ”The human knee joint is like a non-stop running machine bearings, with increasing age, the surface cartilage will also have different degrees of wear and tear, excessive exercise and poor lifestyle habits will accelerate the aging of the joint, which will lead to lesions.” It is understood that osteoarthritis is a chronic progressive bone and joint disease that seriously endangers the health of middle-aged and elderly people. According to incomplete statistics, the incidence of osteoarthritis is the highest among all types of arthritis in China, accounting for about 80 percent of the total, and the prevalence of osteoarthritis is more than 42 percent among people over 60 years old, with a higher incidence among women than men. The onset of osteoarthritis is usually mild or moderate intermittent boredom and swelling, followed by persistent joint tearing pain. The joint may also become swollen, painful to the touch, fluid accumulation, and a popping or clicking sound when moving, and may cause obstruction in squatting and walking up and down stairs, resulting in severe inversion and flexion contracture deformity of the affected limb and eventually joint disability. At the current level of medicine, there is no ability to reverse the course of osteoarthritis, and most patients will continue to develop the disease. In clinical work, older people like Sun are not the only ones who get osteoarthritis, but there is a trend toward a younger onset. Therefore, it is important to take care of the joints early and properly to slow down the aging process. First, pay attention to the knee joint warmth and cold, especially women, in addition to wearing short skirts in winter and less exposed knees, do not neglect the protection of the joints in the air-conditioned room in summer. Secondly, we should do reasonable physical exercise, such as tai chi, jogging, gymnastics, etc., and try to reduce the weight and large activities of the joints, such as climbing mountains, going up and down stairs quickly, or squatting for a long time. In addition, people who are obese should reduce their body weight to reduce the load on the joints. Once knee pain occurs and osteoarthritis of the knee occurs, you should go to a regular hospital in time to avoid losing the best time for treatment. For patients in the early stage of the disease, they can be treated by conservative treatment, that is, non-surgical treatment, including physiotherapy, drugs, injection therapy and Chinese herbal medicine treatment. For example, commonly used physical therapy includes Chinese acupuncture, fumigation, and medical magnetic therapy for knee braces. For those who have swollen joints, severe pain, more obvious destruction of cartilage in the joint cavity or with meniscus damage, free bodies in the joint cavity, and proliferating bone flab affecting walking, acupuncture and cupping can be chosen as treatment. Acupuncture has anti-inflammatory and pain-relieving effects, and promotes blood circulation. By changing the blood flow and blood velocity in the affected area, some pathogenic inflammatory factors can be taken away to improve the symptoms. Patients with advanced knee arthrosis, with significantly limited joint movement, bone deformation and severe pain, need to choose the surgery of artificial total knee joint replacement. It is understood that the artificial joint is one of the most important advances made in the field of orthopedic surgery in the 20th century, which allows patients who used to rely only on crutches to walk, or even only amputation, to walk like normal people, greatly improving the quality of life of patients, so that some patients with advanced joint severely damaged osteoarthritis and some patients with long-term bedridden arthritis, through surgery to stand and walk again. It is a major breakthrough in the field of medicine.
