Knee pain is a common condition in life that we have all experienced at one time or another. It is especially common in athletes, which is certainly related to their high level of exercise, injury and repeated strain. However, in the general population, it is often found that women are more likely to suffer from this condition than men. Why is this? 1, the reason 1, anatomical differences in the female pelvis is significantly wider than the male pelvis, the hip and away from the midline, so that from the hip to the knee and then to the foot of the angle of exotropia increased, walking or exercise in front of the thigh muscle pull, so that the knee patella exotropia force increases, the patella lateral pressure increases, easy to make the patellar cartilage softening, ligament strain, resulting in knee pain. 2, the impact of social factors in the clerical and office workforce, the majority of women, long periods of sedentary, repeatedly bending the knee, reduced activity, easy to make the joint and ligament degeneration, osteoporosis. This will greatly increase the chances of knee pain. 3, the impact of lifestyle habits In many occasions, we find that women due to habitual movements or dress reasons, easy to take both knees and Long or crossed legs posture, when riding a bicycle, both knees next to each other, such hip inward movement is more likely to cause knee valgus pressure, resulting in long-term chronic damage to the knee tissue caused by pain. At the same time too high heel, so that the body’s center of gravity shifts forward, in order to balance the body, the knee must be slightly flexed, so that when walking and standing to increase the extra load on the knee, more likely to make the tissue chronic injury, pain increased. 4, the influence of other adverse factors such as obesity, lack of leg strength, less dress so that the knee is vulnerable to cold and other factors that can easily contribute to joint damage. Second, rehabilitation exercises and knee health care long-term sedentary, pay attention to the joint flexion and extension functional exercises. Scattered, sitting or standing joint flexion and extension exercises are good ways to reduce knee fatigue and pain. Change the poor sitting and walking posture, pay attention to the knees slightly parallel apart when riding a bicycle, and reduce the action of knee inversion. Wear shoes with a lower heel when walking longer distances. Pay attention to keeping the knee warm in winter and prevent the air conditioning from getting too low in summer. Finally, ladies are warned to pay attention to the beauty of their legs. Reducing excess body fat and maintaining a standard weight; increasing leg muscle strength exercises and maintaining the stability of the knee joint can be a good way to prevent knee pain.
