What causes knee pain in teenagers?

The physical health of teenagers is affected by various factors, and they are very prone to various diseases, which cause great harm to their physical health. For example, knee injury is one of the important reasons for problems among teenagers. The knee is located in the joint connecting the calf and thigh and plays a balancing role. What is the reason for knee pain in teenagers? Let’s take a look at the explanation below. I hope everyone can understand it.

1. Obvious trauma, such as that caused by a car accident or a fall, can cause varying degrees of muscle strain, sprain or rupture of the cruciate or lateral ligament, rupture of the meniscus, fracture and dislocation, etc. Calcium deficiency, various joint diseases.

2. Misalignment of the knee (patella), including repetitive subluxation and dislocation, can also cause knee pain. Sometimes their appearance is not obvious, and detailed examination can distinguish whether they are caused by muscle asymmetry or skeletal abnormalities.

3. Osgood-Schlatter disease occurs in schoolchildren aged ten to fifteen. It causes swelling and tenderness at the upper end of the calf bone at the knee, which is particularly painful after exercise. This disease will get better after rest, and the child will not have it again when he grows up.

4. There is a type of knee pain that occurs in adolescents who grow rapidly and do less exercise. The pain is located near the kneecap. This type of child cannot run fast or with big strides, and will suffer from knee pain after the slightest exercise. During the examination, it was found that the flexibility of the lower limb muscle joints was very poor. When lying down, the thighs could not even be raised beyond 90 degrees. This was because the tight posterior thigh tendon caused excessive burden on the kneecap. With just a few months of stretching and flexibility exercises, knee pain will naturally disappear.

5. Ankylosing spondylitis: About 1/3 of patients experience lower limb knee pain during the peak growth and development period of adolescence (12 to 16 years old).

6. Abnormal folds in the knee, femoral osteochondritis, juvenile rheumatoid arthritis, suppurative arthritis, osteomyelitis, synovial osteochondroma, etc. can also cause knee pain.

7. Because the thigh bone and calf bone at the knee are the fastest growing parts of the human body, various benign and malignant bone tumors are prone to occur here. Therefore, teenagers should not take it lightly when they suffer from persistent pain, swelling and heat in the knee. The incidence of bone tumor is one in 100,000, and 80% of them are teenagers. This disease mostly occurs around the knee joint and has no obvious cause. However, adolescents are in the growth and development period. Once genes are out of control, their bones are prone to grow wildly and they may get this disease.
