Tibial plica osteochondritis

　　This disease is prevalent in black children, which is significantly different from other osteochondrosis. The cause is unknown. Some believe that this is due to black children walking on the ground earlier (average 10½ months) than white children (15 months). Early walking causes excessive stress on the medial tibial epiphysis, leading to disordered cartilage development and deformity. Some also believe that this disease is caused by the habit of African black ethnic groups to tie children to their bodies, with abduction of the hips and genu varum, which increases the pressure on the medial tibial epiphysis.

　　This disease mainly causes genu varum deformity. In children with long-standing disease and timely treatment, the medial femoral condyle and tibial cartilage bearing surface of the knee joint may have defects and cystic changes. Some children may have obvious relaxation of the ligaments in the knee joint due to developmental abnormalities.

　　The main manifestation of this disease is bow legs, which is divided into infantile type and adolescent type (6-13 years old), the latter is rare, often caused by trauma and infection, the deformity is not serious, due to the fetal position in the uterus, most infants have bow legs, which will naturally correct after 1 year, so before the age of 2, it should not be diagnosed as this disease arbitrarily.

　　There is no effective preventive measure for this disease, early diagnosis and treatment are the key to the prevention and treatment of this disease, in order to avoid joint damage. As for the suspected etiology at present, preventing infants from walking too early is one of the measures to prevent this disease.

　　The auxiliary examination methods for this disease are mainly X-ray examination, the X-ray manifestations are: the affected lower leg bends inward, showing genu varum, the tibial condyle is enlarged, the superior articular surface is inclined inward, downward, and backward, the medial part of the metaphyseal end of the adjacent epiphysis also expands medially, and spots with uneven or irregular calcification may appear, the medial cortex of the tibia thickens, and the tibial joint造影 shows that the tibial joint surface gradually develops from horizontal to collapse, the medial meniscus compensates with abnormal thickening to maintain joint stability.

　　What foods are good for people with osteochondritis

　　Eat more foods rich in calcium such as fish, shrimp shells, shrimp paste, kelp, milk, and soybean products.

　　For patients with severe genu varum, tibial osteotomy can be performed. It is advisable to do it early. Among a group of 47 tibias, only 3 are older than 8 years old after one osteotomy; among the 21 tibias that need to be osteotomized multiple times due to recurrence of deformity, only 5 are younger than 8 years old. Therefore, some scholars believe that surgery can be performed after the age of 2. Tibial condylar osteotomy is the most commonly used. However, some also add tibial condyle osteochondral blockage or medial joint surface elevation surgery.
