Are bow legs permanent?

No: Most infants are born with bow legs. As they go from infants to toddlers, the bow legs often resolve. If your toddler still has bow legs by age 2 or if they have a significant difference in the bowing of each leg, you should contact your pediatrician.

No: Babys are folded up tight in the womb, often causing initial bowing.Once they start walking, the pressures over their legs produces a change in shape & the knees may actually angle in at 4 & straighten at 6 or so.In decades of practice I have not had one that didn't self correct.I occasionaly get xrays to monitor the more pronounced cases. Compairing films 6mo apart can show progress.

Depends on your age: Bow legs and in-turning feet are common in toddlers, worst at about age 2. Then progression to knock-knees happens, worst about age 7. The average adult has a few (5-7) degrees of knock-knee. Milder persistent bow-legs are left alone. If you have bow-legs when you quit growing, the it is permanent, short of surgical correction.

Bow legs can vary: There is variation during birth to age 6-8. There may also be post traumatic causes that linger. Also, genu varus can progress in adulthood with tibial bowing in some with osteoarthritis.

Not really: Depending on where someone's stage is in life (adolescent, child, puberty), bow legs do not necessary have to be permanent.
