Looped leg, also known as inversion of the knee in medical terms, is formed due to physiological reasons, pathological reasons and so on.
1. Physiological reasons: after birth, children may have in-turned knees, and the lower limbs of children will gradually straighten around the age of two, and approach the age of six to seven years old. Most of the inversion of the knee before the age of two is physiologic.
2. Pathologic causes: it refers to a variety of diseases that cause inversion of the knee.
(1) Metabolic diseases: such as rickets, renal osteodystrophy and so on.
(2) Abnormal bone development disease: such as epiphyseal chondrodysplasia.
(3) Other: such as trauma, infection, excessive obesity and so on.
These factors will make the strength and length of the muscles on the inner and outer sides of the knee joint unbalanced, if not corrected for a long time, the lateral ligaments will become lax, and in the long run, the inner femur and tibia will rub against each other and form the inversion of the knee.
Physiological inversion of the knee can be corrected by itself with growth and development. If it is a pathologic knee inversion, you should consult a doctor in time to clarify the disease and then target treatment.
