The knee joint is the hub of the leg, which silently supports the weight of the body and is the important load-bearing joint of the human body. In addition to sleeping, sitting, etc., the knee joints are mostly in a high-pressure working state during the day, and the weight of gravity can be not small.
When walking, the weight of the knee is about twice the weight; when climbing or climbing the stairs, the weight of the knee increases to 3-4 times the weight. People walk easily and up the stairs every day, but the knees are under such pressure.
So how do you find knee joint degeneration early?
What is its logo?
I believe that today's sharing can give you the answer.
How to distinguish early degeneration of the knee joint?
When the knee is degenerated early, it is usually not red or swollen. It is usually not painful when walking. However, if the following conditions occur, be careful.
Signal 1: Unexplained pain in the upper floor or downstairs.
The knee joint consists of three bones, the femur is attached to the upper thigh, the tibia is attached to the lower calf, and the tibia is in the middle. When walking down the road, the weight of the body is mainly transmitted from the lower part of the femur to the tibia. The curvature of the middle jaw is small and the weight is light, so there is no pain. When going up and down the stairs, the knee joint should overcome the body's gravity and sports impact force, plus the joint movement angle is large, repeated bending and straightening, the weight of the tibia is obviously increased, and the wear is also aggravated.
Originally, our joint surface has smooth cartilage protection, and there are some joint fluids for lubrication, but as we age, the cartilage gradually becomes rough and the joint fluid is reduced. At this time, if the joint is heavy and the friction is frequent, it will stimulate the nerve endings under the cartilage, which makes people feel pain.
Signal 2: If you don't press it, it hurts.
This also indicates that the cartilage surface has been degraded. After being pressed, the buffering effect is reduced, the protective effect on the tibia is reduced, and the knee joint is a help signal.
In addition to the two signals mentioned above,
You can also kneel down on one leg.
To judge whether the knee is good or bad.
One-leg squat method:
Without any load and without external force, one leg stands, the knees are slightly bent, the other leg is bent, the toes are slightly above the ground, and this body is maintained, then the whole body is squatting as far as possible, and the process is slow. Carry out as much as possible to maintain body balance. After a few seconds, stand again and return to the initial position. Some people are unable to coherently complete the whole movement because of poor balance of the body, or excessive pressurization in the lower jaw, short-term intolerance, and soreness, which is normal. The key is to pay attention to the knee joint, there is no pain, only pain means abnormal, you need to go to the hospital as soon as possible.
