Understanding What’s Normal and What Needs Attention
Knock knees, or genu valgum, is a condition where a child’s knees angle inward and touch each other when standing straight, while the ankles remain apart. It’s a common part of normal growth—but sometimes, it may signal an underlying issue. So, how do parents know when to be concerned?
Is Knock Knees Normal in Young Children?
Yes, in most cases. Knock knees are part of natural development. Here’s how leg alignment changes with age:
- Birth to 18 months – Bow legs are common.
- 2 to 4 years – Knock knees appear.
- By age 7 – Legs usually straighten out naturally.
So, mild knock knees in toddlers is usually nothing to worry about.
When to Worry About Knock Knees
While often harmless, consult a doctor if:
- Your child is older than 7 and knock knees haven’t improved.
- The condition is severe or one-sided.
- Your child complains of pain in the knees or legs.
- There’s difficulty walking or running.
- There’s rapid progression or worsening over time.
- There’s a family history of bone disorders.
Possible Underlying Causes
If knock knees don’t resolve naturally, causes may include:
- Rickets (Vitamin D deficiency)
- Bone infections
- Injuries to growth plates
- Obesity
- Genetic conditions like skeletal dysplasia
Diagnosis & Treatment
A pediatrician or orthopedic doctor may perform:
- Physical exam
- X-rays for bone alignment
- Blood tests (if nutritional or metabolic issues are suspected)
Treatment Options May Include:
- Monitoring for age-appropriate cases
- Bracing or shoe inserts (rare)
- Physical therapy
- Vitamin supplements
- Surgery (only in severe or unresolved cases)
Can Exercises Help?
Yes, in mild cases, strengthening and stretching exercises for the hips, thighs, and legs can support better alignment. However, always follow a doctor’s or physiotherapist’s advice.
Conclusion
Knock knees are often a normal part of growing up and correct themselves over time. But if the condition seems unusual, painful, or persistent beyond age 7, it’s best to seek medical advice. Early intervention, when needed, can prevent complications and support healthy development.
