Knock Knees
A leg alignment where the knees touch but the ankles stay apart — common and harmless in young children, helped by exercise and good nutrition.
📝 Summary
In short: A leg alignment where the knees touch but the ankles stay apart — common and harmless in young children, helped by exercise and good nutrition.
Common causes: A normal developmental stage in young children; Vitamin D or calcium deficiency (rickets); Injury to or problems with the growth plate near the knee.
First thing to try: For young children, reassurance and normal active play are usually all that's needed.
See a doctor if: Knock knees that are severe, one-sided, or getting worse
🌿 Overview
Knock knees describe legs that angle inward so the knees touch while the ankles stay apart when standing. It is a normal stage in many young children and usually straightens on its own by about age seven. When it is marked, persists into older childhood, or appears in adults, it deserves a check, since it can strain the knees over time.
In toddlers and preschoolers a mild knock-kneed stance is part of normal leg development and corrects itself as the child grows. A more pronounced or one-sided angle, or one that worsens with age, can point to a nutritional cause like rickets (too little vitaminA natural substance your body needs in small amounts to stay healthy, like vitamin C or D. More → D), an old injury, or a growth-plate problem.
For the common, mild form, no treatment is needed beyond healthy growth — good nutrition, vitaminA natural substance your body needs in small amounts to stay healthy, like vitamin C or D. More → D from sunlight, and normal active play. When the angle is severe or causes knee pain, strengthening exercises, supportive footwear, and sometimes medical correction help protect the joints. Persistent or worsening cases should be evaluated.
Common signs
- Knees that touch while the ankles remain apart when standing
- A gap between the ankles with the knees together
- Sometimes knee or hip discomfort, or tired legs
