How to protect your knees during sports

The knee is a very important part of the human body. Only when the knee is healthy can the body remain in a relatively healthy state. If there are symptoms of disease in the knee, the normal activities of the human body will be greatly affected. In severe cases, it may also cause some movement disorders. So be sure to protect your knees. So what are some ways to protect your knees during exercise? Now let us introduce it.

The knee joint is the most important joint in human movement. Running, jumping, squatting and other movements all require the cooperation of the knee joint. In daily exercise, the knee joint is one of the most vulnerable parts. People who have injured their knees when they are young have several times higher rates of arthritis in middle-aged and elderly people than those who have not suffered any injuries. Therefore, during exercise, you must pay attention to protecting your knee joints.

The knee joint is composed of the thigh, tibia, patella, and fibula, and has a complex structure. Football, basketball, sprinting and sudden jumping may cause knee injuries. There are four common types of knee injuries:

First, anterior cruciate ligament rupture: This is the most common serious sports injury to the knee. About half of them are caused by twisting the knee while grabbing the ball in basketball, and sometimes a sound can be heard. At this time, the knee joint will swell up quickly, and the knee will not be able to fully straighten. It can only be bent at about 30 degrees, and it will be impossible to walk on the ground.

Second, medial ligament injury: If the knee is in an outward valgus position when injured, the medial ligament of the leg will often be injured, accompanied by pain, tenderness and bruising.

Third, meniscus rupture: It often occurs when landing from a jump, with the knee landing slightly inward or outward. The pain is mild and you can walk. The joint sometimes swells slightly, but it disappears quickly. If the broken fragments are large, they will get stuck in the middle of the joint and make the knee unable to move. Just twist the knee slightly. A ruptured meniscus does not cause much movement disorder, but you may feel pain on the inside or outside of the joint when running or jumping.

Fourth, articular cartilage rupture: If the articular surfaces of the femur and the knee joint collide too violently, it may cause cartilage rupture and joint hematoma.

The methods to protect your knees during exercise are introduced above. The knees are under a lot of pressure during exercise. If you don't take preventive measures, it will not help the health of your knees. Especially when doing some running and jumping exercises, you must take precautions. Warm up thoroughly before any activity.
