What causes knee pain in children?

Children are the most precious treasures in every parent’s heart, and their health is always on the parents’ minds. If they feel the slightest bit of discomfort, parents would like to call the entire hospital to treat their children. With the rapid development of technology, every household has air conditioning, and the hot summer is no longer so unbearable. However, because of this, many children suffer from knee arthritis. Today I will introduce you to this disease and how to prevent and treat it.

To prevent knee pain, you can do the following:

1. Eat a balanced diet and choose high-quality protein such as milk and soy products, eggs, lean meat, fish, shrimp, chicken, dried shrimp skin, kelp, seaweed, crispy fish, oysters, seaweed, sesame paste and other foods. Eat more foods rich in vitamin C: such as fresh vegetables and fruits, which can promote calcium absorption. While preventing osteoporosis, it can also promote the knee joint to produce more lubricating fluid to maintain normal movement.

2. Correctly apply the principles of human mechanics to solve practical problems in life

Use the full-body rotation belt to rotate your torso; do not twist your body to work. When squatting, the load on the knee joint is 3 to 6 times your body weight, so it is not advisable to squat for a long time. Work as large muscles or muscle groups as possible. For example, when lifting heavy objects, the waist muscles must cooperate with other muscle groups to reduce the burden on the knee joints.

2. There are some rules for wearing shoes. The front of the shoe should be loose and the insole should be slightly thicker to reduce wear on the knee joint. Try not to wear high heels to reduce damage to the knee joints. If you must wear high heels in certain situations, it is best not to exceed 5 cm. Try to reduce the time you wear them. After returning home, do barefoot exercise and soak your feet in hot water to eliminate fatigue.

3. Keep your weight within a normal range. Losing weight helps reduce the burden on your joints.

4. In cold seasons, you should always add clothes and keep warm. Prevent your knee joints from getting cold and wear knee pads if necessary.

5. Choosing appropriate physical exercise can promote the body's metabolism, increase bone toughness, increase bone mass, reduce the load on the knee joint, and enhance muscle strength. You can choose walking, swimming and other exercises. When doing outdoor sports, wear comfortable sports shoes (sports shoes have a certain shock-absorbing effect). However, it is not suitable to do sports such as mountain climbing, going up and down stairs, etc.

6. Functional training of quadriceps and biceps femoris

The thigh muscles are the quadriceps femoris in the front and the biceps femoris in the back. The function of the quadriceps femoris is to extend the calf, flex the thigh, extend the knee joint and flex the hip joint; the biceps femoris is mainly responsible for controlling the movements of knee flexion and thigh extension, and its function is to extend the hip and flex the knee.

(1) Quadriceps training:

① Patellar movement: The patient lies in supine position with the knee extended and performs isometric contraction and relaxation of the quadriceps femoris. The patella can be seen moving up and down, which is called patellar movement. You can also sit on a chair, straighten the affected knee, place the foot on the ground, contract the quadriceps isometrically, pull the patella upward, hold for 5 seconds, then return to the starting position, and repeat 20 to 40 times.

② Knee extension exercise: The patient sits with the knee flexed 90°, and then extends the knee alternately to the left and right sides. Keep the straight position for 5 seconds, then return to the original position, and repeat 20 to 40 times;

③ Straight leg exercise: The patient lies on his back, raises his straight legs 45 degrees, holds for 5 seconds, then puts them down, and repeats 20 to 40 times.

2. Biceps femoris training: ① Lie on your stomach, slowly bend your knees to 90°, and hold for 5 seconds, then put them down, alternating between the two positions, and repeat 20 to 40 times.

② Lie on your back, bend your knees and place your feet flat on the floor. Lift your hips and lower back so that the middle of your body is at a 45° angle to the ground. Hold for 5 seconds, then lower your body. Repeat 20 to 40 times.

Functional training requires perseverance, gradual progress, and daily persistence. Each training session should end when the muscles feel sore and hot, and you feel relaxed the next day. It is not advisable to overdo it.
