[Ben Wang - shoes and life] when sprained knee, first injured the medial collateral ligament is usually (MCL), which starts from the femur, tibia beyond the inside of the knee. If you have to climb for a long time on your hike, such as going up the stairs, you should stop and rest from time to time because the longest climb is the worst for the knee joints.
Followed by the knee is a problem, although many sports will cause the knee to wear, although we are not as dangerous as skiing or racing on foot, but the injury to the knee is very common, such as walking on a cobblestone On the road, one will inadvertently fall, and often on foot, the wear on the knee will slowly accumulate and increase.
With the passing of the winter and the arrival of spring, more and more people are walking out of the air. They are not in a proper posture or are brave in walking. Excessive exercise will not only bring no exercise effect, but will not improve the heart and lung function. It may also bring about Sports Injury. Knee injuries are more and more common in hikers. This type of injury has the potential to cause defamation. It does not cure overnight and may lead to osteoarthritis and even total knee replacement.
However, it is gratifying to note that the knee injury is almost always due to personal error, that is, it can be almost completely avoided, so at the beginning, we first understand our knee joints and then we must clearly protect it. .
The structure of the knee joint can easily support the movement. Normal movement is part of the joint task, but walking in weight-bearing, especially down the mountain, has aggravated the test of this curved joint. On average, one person walks about 2 million steps per year. This statistic does not include those wild hiking trips. But the knee injury is not just a matter of the number of walks. When walking on the floor, the pressure on your heel is three times your own weight; when jogging on a flat surface, this pressure is about five times your own weight. Walking down the hill is similar to [url =] running [/ url], if you also carry a large backpack, then the pressure will also include five times the weight of the backpack.
The knee has its own shock absorber: the meniscus, which is two-and-a-half-moon cartilage, at the intersection of the femur and the tibia. It functions as a cushion to disperse weight. In addition, there are articular cartilage, which is like a smooth elastic lining, covering the top of the bone where the knee meets, and minimizing friction when the bone ends move relative to each other. However, these two types of cartilage can only reduce a certain amount of impact force, when carrying a heavy backpack hiking, especially walking down the mountain, it is easy to make a qualitative knee disease. A car's shock absorbers age, you can also get a new one, but for the knee joint, you can't just change a joint, you basically have no choice.
The structure of the knee joint is complex. It is not like a scapular fossa, nor is it like a sucker-like hip joint. A knee joint is not as deep as a joint socket. It is more like a hinge on the door. An ingenious hinge of the organ contains a On the slightly longer side of the femoral head, the four major ligaments, some of which are cruciate ligaments, bundle the joints together. Each time the knee flexes and stretches, they pull the ligaments. A joint that is not strong enough to act as a lever for the leg when the movement is accelerating, and as a brake when decelerating. In fact, any quick turn involves twisting in the middle of the leg, which may cause pain in the knee, or worse.
