Knee osteoarthritis is the most common form of arthritis, often seen in middle-aged and older adults, and as a chronic progressive degenerative disease, it threatens the normal activities of nearly one-third of adults worldwide. Knee osteoarthritis has its roots at a young age and is increasingly becoming younger. Theoretically, gravity causes the cartilage in the knee joint to degenerate by the time humans are in their 20s due to upright walking. Therefore, it is important to protect your knee joints in your 20s. So, how can you prevent knee osteoarthritis from occurring? In our daily life, we should pay attention to the following five points: First, weight control Patients with knee arthritis due to body weight have occupied a large proportion of the patient group in recent years. In addition to genetic and medication factors, the most important reason for this is the poor dietary habits, overfeeding, overeating, heavy taste, loss of control of the total amount of food intake, coupled with insufficient exercise, resulting in excessive pressure on the joints, the load is too heavy and the disease. If you are overweight, your joints will be overburdened. Second, avoid living in a cold and wet environment for a long time. When encountering hazy, wet and cold weather, low temperature and high humidity, it will make the knee joints uncomfortable and soreness, weakness of the legs to beat the softness, which are the manifestations of knee osteoarthritis. Therefore, adding more clothes and blankets in response to seasonal changes, reducing field activities, and avoiding direct blowing of air-conditioning can effectively prevent the onset of knee osteoarthritis. Climate change and poor living environment are important external factors for the development of knee osteoarthritis. Especially in summer, the indoor temperature and humidity must be controlled in the appropriate range of the human body. Third, control climbing and long-distance walking Now people’s awareness of sports and health care is getting stronger and stronger, many friends choose to climb mountains, climb stairs, fast walking and other ways to fitness. But if the exercise is excessive, it will also bring negative impacts, accelerate the wear and tear of knee cartilage, leading to knee arthritis in young people in advance. In fact, climbing mountains, heights and other forms of exercise are not beneficial to everyone, on the contrary, for some people are harmful forms of exercise. Experts suggest that if you have knee discomfort, it is best to ask an orthopedic specialist to do a joint function assessment before you climb the mountain to avoid unnecessary damage. Walking exercise is simple and effective, but we should also pay attention to the way and method. It is recommended that you choose to walk on level ground and strictly control the number of steps per minute to no more than 100, and the duration of exercise to no more than 1 hour. Exercise over the range, will directly lead to joint wear. Fourth, try not to wear high-heeled shoes Since the invention of high-heeled shoes since the date of invention, the majority of women loved, because after wearing a more graceful posture, gait is more beautiful, however, the human evolution of millions of years to walk upright, the skeletal system can not be adapted to the invention of high-heeled shoes within a hundred years. With the development of society, high-heeled shoes heel is also designed more and more high, increasing the beauty of women at the same time, but also lead to increased foot force, in order to maintain body balance, must be forward to the body, tense knee joints, which will inevitably lead to knee ligament degradation and wear and tear of the cartilage. It is recommended that women who love beauty in addition to special requirements to wear high-heeled shoes, leather shoes, daily or wear flat, loose, soft shoes are appropriate to absorb the impact of gravity, reduce the load on the knee joint. Fifth, female friends pay special attention to the rate of women suffering from knee osteoarthritis is far more than men, which is determined by the special physical condition of women. Especially after menopause, the body of estrogen declined, the whole body bone loss accelerated, cartilage thin, brittle, intolerant of wear and tear, if this time to start a large number of calcium and protection of the knee joint, a little too late. Therefore, for women, the health care of the knee joint is to start early and persist. In addition to the above precautions, you should also take sunshine, drink milk, and take vitamins A, C, E, and D according to your doctor’s prescription, which are good for preventing knee osteoarthritis. Especially the sun, can activate the body’s vitamin D, activated vitamin D can help the body to absorb and utilize calcium, phosphorus, so that the human body has stronger bones, will also help to prevent the occurrence of knee arthritis.
