Check the gap between your ankles
If your knees touch but your ankles stay apart, this may indicate knock knees
Measure the distance between your inner ankles while the knees are together
Compare both legs to see if the alignment looks symmetrical
Look at your knees from the front while standing naturally
Observe whether the knees angle inward toward each other
Check your walking pattern for inward knee collapse
Compare your leg alignment in a mirror
If you are unsure, have a doctor or physiotherapist assess your leg alignment
