Joint pain in children is commonly caused by the following diseases:

1. Rheumatic fever: It can easily cause pain in large joints such as the ankles, knees, hips, wrists, elbows, and shoulders, namely 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 condition 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.

3. Allergic purpuric arthritis: Clinically, one or more joint swelling and pain are common, along with skin purpura. In a few cases, purpura occurs from time to time, so it is easily overlooked. If not treated in time, it can cause kidney damage.

4. Acute suppurative arthritis: 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 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 symptoms are mild pain in one thigh and knee joint. The pain worsens during movement and the patient may limp. The disease heals on its own after 3 to 4 weeks.

6. Others: Autoimmune diseases such as systemic lupus erythematosus, mixed connective tissue disease, etc.; infectious diseases such as tuberculous osteoarthritis, etc.; some malignant diseases such as leukemia, etc., 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.
