Baby's knees cannot straighten

The physical condition of the baby is what parents are most concerned about. Many families now choose to have only one child, so naturally the child becomes a treasure. In daily life, many parents find that their baby’s knees cannot be straightened. This situation is certainly worrying, but they don’t know if there are other obvious abnormalities, and they are not sure whether it is temporary or there is a problem with the knees. So, why can't babies straighten their knees? Let's take a look below.

Generally speaking, it is normal for young babies to have bent calves. Because the muscles attached to the long bone on the inside of his calf (tibia) are thinner than those on the outside, the baby's calves appear a little bent, which is actually an illusion. The fetus also has inward-turned toes, which is caused by the fetus being cuddled in the mother's womb for a long time.

After the baby is born, his limbs will slowly "stretch out", but some babies are slow to "stretch". When they learn to walk, their toes will bend inward and they will walk unsteadily. At around 1 year old, their legs will be slightly bent, and X-rays will also show bent calf bones, but there are no X-ray manifestations of rickets. This is because the children at this age have just started to walk, and their legs cannot bear their own body weight well, so their calves are temporarily bent. Generally, they will return to normal by the age of 2-3, and X-rays also show that the original bending of the calf bones has been corrected.

Both situations are normal. For babies with introversion, the soles of their feet will tilt inward, but there will be basically no problems with their feet and knees. Babies with "duck feet" are less stable when learning to walk and are more likely to fall. If the baby's condition has not improved after the age of 2, the doctor may put a splint on the baby's foot and use a limb brace to correct the foot position, which may take a year. If the condition has not improved by the age of five or six, the doctor will consider performing surgery to loosen the muscles in the child's feet.
