If you’ve noticed your child’s legs curve outward or inward, you might wonder—is this normal, or should I be concerned? Many children go through stages where their legs appear bowed or knock-kneed as part of normal growth. But in some cases, these patterns can indicate an underlying orthopedic issue.
In this blog, we’ll explain the differences between knock knees and bow legs, what’s considered part of healthy development, and when to consult a pediatric orthopedic specialist.
Understanding the Terms
Bow Legs (Genu Varum)
The legs curve outward at the knees, creating a noticeable gap between them when the feet are together.
Knock Knees (Genu Valgum)
The knees touch or angle inward while the ankles remain apart when standing straight.
What’s Normal in a Growing Child?
Leg alignment changes naturally as children grow:
- Birth to 18 Months: Bow legs are common due to fetal positioning and begin to straighten with walking.
- 2 to 4 Years: Legs often swing into a knock-kneed appearance—this is a normal developmental phase.
- By Age 7: Most children develop a normal, straight leg alignment.
These changes are usually symmetrical and painless. If your child’s walking is normal and there’s no discomfort, observation may be all that’s needed.
When to Worry
See a pediatric orthopedic specialist if your child:
- Has severe or worsening bowing/knock knees beyond age 7
- Complains of pain in the knees, hips, or ankles
- Has an uneven leg shape or gait (limping, waddling)
- Exhibits asymmetry (only one leg is affected)
- Has difficulty running, jumping, or keeping up with peers
- Shows signs of underlying conditions like rickets, Blount’s disease, or bone infections
Causes of Abnormal Leg Alignment
While most cases are harmless, some may be linked to:
- Nutritional deficiencies (like Vitamin D, leading to rickets)
- Blount’s disease, a growth disorder of the shinbone
- Genetic or metabolic disorders
- Injuries to the growth plate
- Neuromuscular conditions
A professional evaluation helps distinguish normal development from conditions that require intervention.
Diagnosis and Evaluation
At Child OrthoCare, we assess leg alignment through:
- Physical examination
- Gait observation
- X-rays to measure bone angles and growth plate status
- Additional testing if underlying conditions are suspected
Treatment Options
For Normal Developmental Cases:
- Observation with regular monitoring
- Reassurance for parents that growth is on track
For Problematic Cases:
- Bracing or orthotics in younger children with mild deformities
- Physiotherapy to improve alignment and muscle strength
- Nutritional supplements for rickets or deficiencies
- Surgical correction in severe, persistent, or asymmetrical cases
