What causes knee pain in children?

When people talk about knee pain and back pain, they must think of adults, but what we want to talk to you about today is knee pain in children. Every baby is the apple of the parents’ eyes from the moment they are born. Parents carefully care for the baby’s growth. When a child has knee pain, parents must be very worried. So what exactly is causing knee pain in children? Let me explain!

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, 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: It mostly occurs between the ages of 4 and 10. The condition can be acute, accompanied by 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 joints are commonly swollen and painful, with skin purpura. 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: more common in infants and young children, sometimes secondary to injuries 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 symptom is 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. Growing pains: Children grow very fast during this period, and can grow 7-8 cm each year. Because bones grow rapidly, while the surrounding nerves, tendons, and muscles grow relatively slowly, pulling pain will occur.

When children experience knee pain, it is important to pay attention to whether they have a history of injury and whether they have infectious diseases. If synovitis or other osteoarthritis occurs in the knee joint, parents must pay attention to it. We must never neglect our children's health. The best thing to do is to see a doctor and get treatment promptly.
