Every parent wants their child to grow up healthy. It is a journey filled with excitement, from their first steps to their playful runs. But sometimes parents notice something unusual: the knees appear to angle inward, touching each other while the ankles stay apart. This condition, often called knock knees, also known as genu valgum, is common in children under seven and usually part of normal growth. Still, experts warn that in certain cases, it could signal a deeper problem that deserves medical attention.

What Exactly Are Knock Knees?
Knock knees occur when a child stands upright, and their knees meet while the ankles remain separated. In most toddlers, this happens naturally and self-corrects as they grow older. By the age of seven, the legs usually straighten out on their own.
However, if the inward curve of the knees continues beyond age seven, worsens over time, or interferes with walking, it might indicate an underlying issue such as nutritional deficiencies, bone development disorders, or even childhood obesity.
Why Early Detection Matters
Dr Aashish Chaudhry, Director and Head - Orthopaedics and Joint Replacement, Aakash Healthcare, Delhi, points out that many families delay seeking care. “We often see parents overlook visible deformities like knock knees, believing their child will simply ‘grow out of it.’ In many cases, that’s true. But waiting too long can lead to long-term problems with posture, walking, and even joint pain in adulthood,” he explains.
Persistent knock knees can impact posture, balance, and joint health later in life. That’s why early detection is key.
According to StatPearls Publishing, knock knees are usually reported in children 3-5 years of age. The most common site of pathologic deformity is the distal femur, the part of the thighbone; however, it can arise from the tibia, or shinbone, as well.
The Role Of Lifestyle And Nutrition
Modern habits such as reduced outdoor play, limited sun exposure, and poor diets are quietly weakening children’s bones. Dr Chaudhry notes, “We are seeing more cases linked to rickets and childhood obesity. Our modern lifestyle, reduced outdoor activity, and unhealthy diets are quietly damaging children’s bone health.”

Treatment Options
The encouraging news is that knock knees are treatable, especially with timely care. Mild cases may only need monitoring and simple exercises, while more severe cases might require braces or surgery.
To make treatment accessible, Dr Chaudhry and his team launched the Pink Bones initiative in partnership with the ANVKA Foundation. The programme offers free check-ups, physiotherapy, and surgeries for children from underprivileged backgrounds. “The impact of this initiative extends far beyond bones,” says Dr Chaudhry. “When a child walks correctly, runs confidently, and engages fully in school and play, their whole life improves.”
Red Flags Parents Should Watch Out For
Parents should consult a paediatric orthopaedist if they notice:
- Knock knees continuing beyond age seven
- A large gap between ankles when knees touch
- Frequent leg pain, limping, or difficulty walking
- Symptoms worsening instead of improving with age
Conclusion
Knock knees are often just a phase in growing children, but they should not be ignored if they persist or cause discomfort. With the right nutrition, active play, and timely medical care, children can overcome the condition and lead healthy, active lives.
“Sometimes, what looks like just growing pains may actually be a call to action. When addressed early, it can lead to a healthier, stronger future,” Dr Chaudhary concludes.
