Teen knee pain

Introduction Knee pain is quite common during adolescence. It is generally believed that due to the rapid growth and development, the intake of calcium can not meet the needs of the body's growth and development, and the blood calcium level is reduced. But some are caused by trauma and disease.

Cause

Obvious trauma, such as caused by a car accident or fall, can result in varying degrees of muscle strain, sprains or fractures of the cross or lateral ligament, rupture of the semilunar cartilage, fractures and dislocations. Calcium deficiency, various joint diseases.

Several common diseases:

Knee (tibia) malposition, 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 abnormal skeleton.

Osgood-Schlatter disease, a school child between the ages of ten and fifteen years old, presents swelling and tenderness at the upper end of the calf bone of the knee, and is particularly painful after exercise. This disease will be good after a break, and the child will not commit another crime when he grows up. There is a type of knee pain that occurs in fast-growing, less-motivated adolescents with pain in the vicinity of the kneecap. This kind of child can't run fast, and can't run big. It is called knee pain after a little exercise. After checking, it can be found that the softness of the muscles and joints of the lower limbs is very poor. When lying down, the thighs can't even lift 90 degrees. This is because the back of the thighs is too tight and the knee bone is too heavy. As long as a few months of stretching and soft movement, knee pain will naturally disappear.

Ankylosing spondylitis, about one-third of patients have knee pain in the lower limbs during the peak period of adolescent growth (12-16 years old).

Abnormal creases in the knee, femoral segmental chondritis, juvenile rheumatoid arthritis, septic arthritis, osteomyelitis, synovial osteochondroma, etc. can also cause knee pain. Because the thigh bone and calf bone of the knee are the fastest growing places in the human body, all kinds of benign and malignant osteomas are good for this, so the young people suffer from persistent pain, swelling and heat in the knee. Take it lightly. The incidence of osteoma is one in 100,000, and 80% are adolescents. The disease mostly occurs around the knee joint, there is no obvious cause of the disease, but the adolescent is in the stage of growth and development, once the gene is out of control, it is easy to grow bones and grow, and get the disease.

In addition to bones, there are many muscles, ligaments and cartilage in the knee. Therefore, in addition to medical history, physical examination, and general X-ray, there are fashion photography, arthroscopy, X-ray computed tomography, MRI and biopsy. In order to get a normal diagnosis; effective diagnosis can only be implemented if the diagnosis is correct. The human bone needs calcium to supplement the nutrients. As long as there is enough calcium, the bones will be hard, lack of calcium, and the bones will not be stressed. Once they are stressed, the joints will be painful.

Differential diagnosis

Differential diagnosis of adolescent knee pain:

1. Post-knee swelling and pain, limited activity: The cystic cyst is more common in middle-aged cases than in middle-aged cases. Males are more than females, resulting in mechanical knee extension and knee flexion limitation. The pain is lighter and the tension is obvious. The patient's complaint is often characterized by a gradual swelling in the litter area, with pain in the back of the knee. Occasionally cysts can be oppressed to block venous return, causing calf edema. When the cyst grows to a certain extent, the knee flexion and extension activity is limited.

2, underarm pain: one of the signs of instability of the humerus, tenderness is mostly distributed in the inner edge of the tibia and the medial support zone. When the examiner presses the patient's tibia and performs the flexion and extension test, it can induce subgingival pain. The clinical tenderness is sometimes inconsistent with the painful part of the patient's complaint.

3, humeral pain: humeral femoral pain syndrome in the early stage of walking, up and down stairs, knees when standing up, there will be pain in the knees, in severe cases there will be sudden knees in the walking room can not force, or even unstable.

4, soreness and swelling of the tibial tuberosity: tibial tuberosity osteophytes are common in adolescents who are often engaged in strenuous exercise from 12 to 16 years old, more men than women. It is characterized by soreness and swelling at the tibial tuberosity, which is a knee disease that is overused and damaged.

5, knee pain: tibia knee pain syndrome is a professional vocabulary that describes the pain in front of or around the humerus. Patellaofemoral Pain Syndrome, also known as anterior knee pain, is caused by abnormal movement of the femur during flexion.
