Knee osteoarthritis is no stranger to us. According to a survey, more than 1/4 of people over the age of 55 in China suffer from knee pain year-round, which many people believe is age-related. Myth #1: It is normal to have some knee pain as you get older. Osteoarthritis of the knee is also known as degenerative arthritis or age-related arthritis because it often occurs in the elderly. In fact, in addition to age being a major factor in the formation of knee osteoarthritis, it is also related to joint injury, weight, inflammatory damage, genetics, etc. It is not simply aging or degeneration as traditionally thought. Therefore, symptoms of knee osteoarthritis in the elderly are not normal and should be seen by a doctor promptly. Myth 2: People with knee osteoarthritis should exercise hard. Since the disease is caused by wear and tear of the articular cartilage, blindly squeezing and rubbing the so-called hard exercise will aggravate the wear and tear of the cartilage lesion and even make it peel off. The surface of normal knee joint has about 3-5 mm thick white transparent cartilage, which is elastic, although the cartilage will gradually wear thin with age, but if over-activity will accelerate the wear and tear of cartilage. Therefore, exercise should pay attention to the protection of articular cartilage, should avoid or limit the following exercises, such as weighted squatting, rapid walking up and down stairs, high-intensity confrontation sports, climbing, weight lifting, sprinting and other strong abrasive sports. Myth 3: Knee pain is caused by bone spurs. Bone spurs are not the cause of knee pain. They are the result of the body’s compensatory proliferation when the edges of the knee cartilage lack stability due to cartilage wear. In a sense, a certain degree of bone growth can increase the joint contact surface and improve the stability of the joint, so bone spurs have their positive side and there is no need to blindly remove them at all. In fact, one of the main causes of knee pain is due to wear and tear of the cartilage that involves the sural nerve under the cartilage. Protecting the articular cartilage is the main purpose of pain relief. Myth 4: It is better not to move because of knee pain. Patients are often afraid to move because of knee pain, which over time will lead to stiffness of the knee joint, disuse atrophy of the muscles around the knee joint, and then knee instability, which can easily occur or aggravate the damage to the articular cartilage. Therefore, even if the knee joint pain should be properly exercised, the correct way is to walk, swim, etc., practice leg lifting exercise quadriceps, can improve the disuse atrophy of the muscles around the knee joint; in the case of non-weight-bearing (such as sitting), gently move the knee joint, can improve the mobility of the knee joint, the key is to exercise the right way. Myth #5: Oral medication can be used for osteoarthritis of the knee. Osteoarthritis of the knee is caused by structural changes in the cartilage of the joint, and is also closely related to the body’s aging and degeneration, the joint is like a machine bearing, long periods of operation will wear aging. As no drugs have been found to regenerate the cartilage, there are no drugs that can turn a degenerated joint into a young one. Medications are only one way to reduce symptoms and slow down degeneration. Myth #6: Fear of minimally invasive arthroscopic surgery. In the early stages, proper joint care and oral medication can slow down the development of the disease, but in the middle stages, if there is significant pain, frequent locking, or free bodies, arthroscopic minimally invasive surgery should be performed to clean up the joint, although this method cannot, but it is like cleaning up a rusty bearing, through two small holes to clean out the joint It cleans out the debris and free bodies in the joint through two small holes, trims the broken meniscus, and flattens the worn cartilage surface. The goal is to slow down the progression of the disease and improve the symptoms. The above is the explanation of knee joint pain awareness uninteresting, do you understand it? Experts remind: in life, we must avoid these misunderstandings, to avoid unnecessary harm and do a good job of prevention of the product!
