Bowlegs is a very common condition in toddlers up to the age of 3 years old. They usually resolve on their own as the child grows, but may indicate an underlying condition such as Blount’s disease if the bowing extends past this time period.
Knock knees is a normal part of childhood development, becoming more obvious between the age of 2 and 5 years old. By the time the child is 8 years old, their legs straighten out with growth. If knock knees occur in an adolescent or teenager, it may be due to an underlying condition such as rickets.
In-toeing is a common childhood condition and one that corrects itself over time. An in-toeing child will usually self-correct during growth by the age of 6 years old. However, if this does not occur, the in-toeing may continue into adolescence; however, it is usually correctable.
Flat feet are a relatively common condition in young children and the arch of the foot develops with time as the child grows. However, in some cases, this does not occur and the foot remains flat. This is caused by one of the bones of the ankle (known as the talus) moving out of its position, causing the arch of the foot to collapse. Flat feet are correctable if the foot has enough flexibility.
