Somewhat similar: Knock-kneed is when the knees are closer together, and the lower part of the leg may be angled away from the center line of the body. This may result in the knees "knocking" together (or rubbing together) when walking or running. Bow-legged is when the knees are farther apart from the midline, and the lower legs angle inward. It can also be caused by rickets or other deficiencies.

How do you tell if you're bow legged or knock kneed?

See an orthopaedist: A physical exam is the easiest way to do this. If you have bow legs (genu varum) your knees are bowed outward. Genu valgum is knock-knees, and the knees angle inward. If any question remains, an x-ray can help.

Knee position: Someone who is bow-legged has knees thy point away from each other. This can be due to an orthopaedic condition such as blount's disease or from arthritis. Knock knees are the opposite direction and point towards each other, this is the less common condition. See a board certified orthopaedic surgeon for evaluation and treatment.

Opposites!: Knock knees (genu valgum) appears as if the knees are bent inward while the lower legs are splayed outward. Bow legged (genu varum) people have legs that appear as if they were straddling a barrel.
