X-leg judgment criteria X-leg refers to two feet side by side, first of all, the two sides of the knee joints touch together, while the two heels are not close together, walking appear two knees fighting each other touch gait. When the feet are together, only the knees can touch, and there is a gap between the thighs and calves.
X-legged harm X-legged effect knee joint is the earliest part of the wear and tear is the patella, this is because the patella is the lower limb flexion and extension of the power “force” device, that is, a “fulcrum” when extending the knee joint. This is because the patella is the “fulcrum” of the lower extremity when extending the knee.
X-leg has the greatest impact on the knee joint, which has a heavy task and relatively poor nutrition, so the incidence of knee strain and sports injuries ranks first among all the joints in the human body, “to put it ‘horribly’, our knee joint only has about 15 years The rest of the time, there are different types of pain for different reasons. And the so-called X-leg for some people may feel no impact, but those who have really studied it will find that X-leg is still a very big impact on people, first of all, people with X-leg, they will not only have a much higher chance of wearing out their pants than usual, but the speed of running is also affected to a certain extent. Therefore, X-shaped legs have a great impact on the joints.
Before the age of 15: The knee joint is in the developmental stage, and most of the growing pains in adolescence occur near the knee joint.
From 15 to 30 years old: The knee joint is in a “perfect state” and works tirelessly. As long as the knee joint tissue is not damaged, it is basically not felt.
Age 30-40: The patellofemoral cartilage is in an early stage of mild wear and tear, with a period of weakness and short-term knee pain lasting a few weeks to a few months, which some people do not even notice. Patellofemoral cartilage is a 3-5 mm thick layer of hyaline cartilage in the human knee joint that cushions the knee joint from the impact of movement. However, because the patellar cartilage has no nerve distribution, it will only sound an “early warning signal” once during the vulnerable period before the full layer wears out, and strenuous exercise should be avoided during this period. From this time onwards, the knee joint can no longer be used as you wish.
40-50 years old: After walking long distances, the inside of the knee joint tends to become sore and painful, which is relieved by rubbing it with your hands. In the knee joint, the meniscus serves to cushion vibrations and maintain stability. Since 60% of the body weight is supported by the medial side of the knee joint, degeneration of the medial meniscus occurs earlier. Because of the nerve distribution in the meniscus, people can feel soreness and pain during the degeneration process. This phenomenon is a reminder that it is time to start taking care of your joints.
Over 50 years old: the knee joint will feel significant pain because the patellar cartilage has reached the end of its “useful life”, the cartilage is worn down and arthritis has developed. This is the time to conserve the use of the joint, reduce strenuous exercise, especially stairs and climbing, and use crutches if necessary to reduce the pressure on the knee joint. In old age, the joints become weaker in comparison, and the effects of X-leg on the joints are quite serious. Therefore, this matter should not be taken lightly.
Correction of X-leg The inner ankle spacing between 3-6cm can be treated non-surgically: massage the outer thigh muscles during the day, and make the two ankles and femoral condyles close together at night after the child sleeps and use bandages or splints to correct gradually; supplement calcium and vitamin D, and get more sunlight.
If the distance between the inner ankles is 6-9 cm, surgical treatment is available: (1) lateral epiphyseal block of the knee joint (2) osteotomy of the femoral condyles
