ABSTRACT

Knock knees, also known as Genu valgum is a kind of deformity in the human body. Knock knees, a part of the regular growth and development, is quite common in children under the age of 6 and 7. Having said that, knock knees may develop later in childhood and adulthood as well. Adults too can develop knock knees. Usually if any individual is suffering from Osteoarthritis or Rheumatoid Arthritis, the chances of he getting knock knees is higher vis-a-vis any other adult.  Let us explore more about Knock knees and its available treatments.

How can you visibly identify knock-knees?

Have you anytime noticed that a few Individuals have a deformity where they are unable to touch their feet together while simultaneously straightening the legs? Such states of severe valgus deformities are typically known as Genu valgum, commonly called “Knockknees“. Knock Knees is a kind of knee imbalance seen when a person who is standing straight with his knees together, but their feet and ankles are apart.

How to know if a person suffers from Knock knees? 

Knock-knees are usually determined by directly measuring the tibiofemoral angle or by measuring the intermalleolar distance. At times, Scans or X-Rays are taken to highlight these deformities.

When a child is born, the deformity that he may encounter is bow legs (Genu varum). This is a condition when the child stands with his feet together but knees apart. This is a normal part of many children’s growth cycle and usually eases out as the child grows – generally, when he attains 2 years of age. There is a possibility that he may get Knock knees (Genu valgum) at the age of four which is a condition quite opposite of Bow legs. Usually, things start becoming normal when he attains eight years and get best at maximum eleven years of age.

It has been noticed in India that, perhaps due to ethnicity and background, the knees of South Indian children tend to straighten out shortly after birth even though they may have been suffering from Knock knees. Also, it has been observed that girls show a higher percentage of these case as against boys.
