Why do children often have knee pain?

Every child is the apple of the family’s eye. When a child is not feeling well, parents will also be anxious. So why do children often have knee pains? First of all, neither parents nor children should be too anxious. Secondly, it is necessary to thoroughly find out the cause of this situation. Next, let us understand why children often have knee pain?

1. Most patients have no history of trauma, and swelling gradually occurs after injury, with the swelling being more pronounced on the injured side.

2. Pain often occurs in a certain body position during exercise, and the pain may disappear after the body position changes. The pain is located in the joint spaces on both sides.

3. Traumatic synovitis of the knee The synovium of the knee is one of the main structures of the knee joint. Synovial cells secrete synovial fluid, which can keep the articular cartilage surface smooth and increase the range of joint motion. When the synovium is damaged due to trauma or excessive strain, a large amount of fluid will accumulate, increasing the pressure within the joint. If it is not eliminated in time, it can easily cause joint adhesion and affect normal activities. Patients will feel pain, swelling, tenderness in the knee joint, and a frictional and astringent sound in the synovium. The most obvious characteristic of pain is that when the knee joint is actively and extremely extended, especially when the knee extension movement is performed with a certain resistance, the pain below the patella will be aggravated, and the pain will also be significantly aggravated during passive extreme flexion.

4. Osteoarthritis of the knee is a disease that is more common in middle-aged and elderly people, mostly women. Excessive weight load is the main cause of disease. The knee joint will be swollen and painful, and sometimes there will be a friction sound when moving the joint. The knee may develop a varus deformity with medial pain.

5. Knee ligament injury: The stability of the knee joint is relatively poor when it is slightly flexed. If it is suddenly subjected to external force and causes eversion or inversion at this time, it may cause injury to the medial or lateral collateral ligament. Medial collateral ligament injuries account for the vast majority of clinical cases. Taking this injury as an example, the patient will have a clear history of trauma, pain and tenderness on the medial side of the knee, pain that worsens when the calf is passively abducted, swelling on the medial side of the knee, and ecchymosis after a few days. Knee joint movement may be restricted.

The above five injuries that cause knee pain cannot be healed by daily care alone. Experts remind: If you have the above pain characteristics, you should ask your doctor for a clear diagnosis as soon as possible to avoid missing the best time for treatment.

Knee synovitis is often secondary to knee osteoarthritis in the elderly. It is mainly due to the mechanical and biochemical stimulation caused by cartilage degeneration and bone hyperplasia, which leads to synovial edema, exudation and effusion of the knee. In young and middle-aged people, it is mostly caused by acute trauma and chronic injury. Acute trauma includes: knee sprain, meniscus injury, collateral ligament or cruciate ligament injury, joint effusion or sometimes blood accumulation, manifested as acute traumatic synovitis of the knee. Sometimes it can also be caused by simple synovial injury of the knee joint, such as minor trauma, or long-term chronic knee strain. Coupled with the invasion of wind, cold and dampness, the knee joint may gradually become swollen and dysfunctional, forming chronic knee synovitis.

The above explains why children often have knee pain. If you don’t have much knowledge in this area, it is necessary to learn about it carefully. Only after you have mastered it, you will not panic when you encounter this situation again, but face it with a positive and optimistic mentality and calm attitude.
