What causes knee pain in children?

Knee pain is a common symptom among the elderly, young people, and even children. Since the knee joint is an important part of the human leg, once it is diseased, it will affect the mobility of the whole body. Therefore, when knee pain occurs, it is necessary to treat the cause in time. If a child has knee pain, you need to consider whether it is caused by the following reasons.

It can easily cause pain in large joints such as the ankles, knees, hips, wrists, elbows, and shoulders, that is, rheumatoid arthritis, which may be accompanied by varying degrees of joint swelling and tenderness. The pain is short-lived and sometimes subsides in just 1 to 2 days. If parents pay attention to it, rheumatic fever can spread to the heart and cause rheumatic heart disease.

2. Rheumatoid arthritis:

Most cases occur between the ages of 4 and 10. The disease can be acute, with symptoms such as fever and joint pain; it can also be chronic. This disease can cause sudden fever and accelerate the disease progression, eventually invading joints throughout the body and causing joint deformities.

Clinically, it is common to see swelling and pain in one or more joints, and purpura on the skin. In a few cases, purpura occurs from time to time, so it is easy to be ignored. If not treated in time, it may cause kidney damage.

4. Acute suppurative arthritis:

It is more common in infants and young children, sometimes secondary to injury or other infectious diseases. The onset is acute, with one or more joints becoming red, swollen and painful, accompanied by symptoms such as fever, irritability, and loss of appetite.

5. Acute hip synovitis:

Most of the children are 3 to 10 years old, and often have a history of upper respiratory tract infection 2 to 3 weeks before the onset of the disease. The main symptom is mild pain in one thigh and knee joint. The pain worsens during movement and the child may limp. The disease heals on its own after 3 to 4 weeks.

Autoimmune diseases such as systemic lupus erythematosus and mixed connective tissue disease; infectious diseases such as tuberculous osteoarthritis; and some malignant diseases such as leukemia are also closely related to joint pain.

Through the above introduction, we know what causes knee pain in children. When children have knee pain, parents must take their children to a regular hospital for examination and treatment. If a disease is found, systematic treatment should be carried out. In addition, attention should be paid to children's daily life care and dietary care.
