Knock Knees


Pediatric Evaluation & Care

Child with knock knees condition in Orange County CA

Understanding Knock Knees (Genu Valgum)

It can be highly concerning for a parent to watch their child walk or run with their knees rubbing closely together while their ankles remain far apart. This angular alignment of the legs is known medically as Genu Valgum, or more commonly, "knock knees." While it looks alarming, the reassuring truth is that for many children, this is simply a normal phase of human growth and development.

The Natural Development Cycle

A child's leg alignment changes drastically during their first decade of life. In the first 12 to 18 months, babies are naturally bow-legged. As they begin to walk and bear weight, the legs bow outward and gradually straighten. However, around age 3 to 4, it is incredibly common for the pendulum to swing the other way, causing the child to become visibly knock-kneed. In typical development, these legs will naturally straighten out again between the ages of 7 and 10.

When Should You Be Concerned?

While most cases resolve on their own, some instances of knock knees require medical intervention. You should seek an evaluation from our pediatric podiatrist if your child experiences any of the following:

  • Asymmetry: The angle is significantly worse in one leg than the other.
  • Pain or Clumsiness: The condition causes knee pain, foot pain, or causes the child to trip and fall frequently while playing.
  • Late Persistence: The knock-kneed alignment persists or worsens past the age of 8.
  • Family History: There is a strong genetic family history of severe leg misalignment or bone disorders.

How Podiatry Helps Knock Knees

You might wonder why a foot doctor treats knee alignment. The answer is biomechanics! The foot is the foundation of the body. Severe flat feet (overpronation) forces the ankles to roll inward, which physically pulls the knees together. By treating the foundation with custom pediatric orthotics, Dr. Soltani can align the foot and ankle, drastically reducing the strain and angular pressure on the knee joints above.

Frequently Asked Questions

Yes, to an extent. It is a very normal part of child development for toddlers between the ages of 3 and 4 to exhibit a knock-kneed stance. In most cases, the legs will naturally straighten out between the ages of 7 and 10.
You should seek a podiatric evaluation if the knock knees are severe, if they cause your child pain or clumsiness, if only one leg is affected (asymmetry), or if the condition persists and worsens past the age of 8.
Because the alignment of the knee is heavily influenced by the foundation of the foot, we often treat knock knees by addressing overpronation (flat feet) using custom orthotics. This aligns the foot and ankle, which in turn relieves stress and angular pressure on the knee joint.
Surgery is extremely rare and is only considered in the most severe, pathological cases where the child cannot walk properly and all conservative bracing or orthotic treatments have failed. The vast majority of children never require surgery.
