Flat feet cause knock knees, known as genu valgum, in children.

the verdict
CONTESTED PARTIAL
Recorded sources
1 source for · 2 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that flat feet cause knock knees, known as genu valgum, in children?

Partly. One clinical-trial description links flat feet and excessive pronation to genu valgum in a postural distortion chain, while NHS guidance and a palaeopathology review attribute childhood knock knees mainly to normal growth or vitamin D deficiency rather than flat feet. The evidence is partial and points in both directions.
