The reverse of knock knee position is known as bow legs.

Knock Knee Position:
The knock knee position, also known as genu valgum, is a condition where the knees touch each other while the ankles are apart. In this position, the lower legs angle outwards, causing the knees to come closer together.

Bow Legs:
Bow legs, on the other hand, are the opposite of knock knees. In this condition, the legs curve outwards, causing a gap between the knees while the ankles touch each other. The shape of the legs resembles the curve of a bow, hence the term "bow legs."

Causes of Bow Legs:
Bow legs can occur due to various reasons, including:
1. Physiological: In infants and young children, bow legs are a normal part of development. Babies are born with bowed legs due to the position they were in while in the womb. As they grow and start to walk, their legs gradually straighten out.
2. Rickets: Bow legs can also be caused by a nutritional deficiency, such as vitamin D or calcium deficiency. This condition is known as rickets and affects the growth and development of bones.
3. Blount's Disease: Blount's disease is a rare condition that affects the growth plates in the tibia (shinbone). It can cause the legs to bow outwards, leading to bow legs.
4. Genetic Factors: In some cases, bow legs can be inherited. Certain genetic conditions can affect the growth and alignment of the legs, resulting in bow legs.

Treatment for Bow Legs:
The treatment for bow legs depends on the underlying cause and severity of the condition. In many cases, especially in infants and young children, no treatment is required as the legs tend to straighten out naturally as they grow. However, if the bow legs persist or are causing functional problems, treatment options may include:
1. Bracing: In some cases, orthopedic braces or splints may be prescribed to help correct the alignment of the legs.
2. Surgery: In severe cases, where the bow legs are causing significant functional impairment, surgery may be recommended. The surgical procedure aims to realign the bones and correct the curvature of the legs.

It is important to consult a healthcare professional for an accurate diagnosis and appropriate treatment plan for bow legs.
