What are the treatment options for bow legs?

Bow legs, also called genu varum, describe an outward curve of the legs. In young children, natural development can make the legs look bowed, so an examination may focus on growth, walking pattern, symmetry and whether the curve is changing. Treatment is not automatically needed when alignment is mild and development is otherwise reassuring.

A clinician may look for an underlying bone or joint problem when bowing is marked, affects one side, continues beyond the expected growth stage, or comes with pain. X-rays or other tests may be recommended when the examination calls for them.

Observation means scheduled checks of leg alignment and growth rather than immediate intervention. Paediatric physiotherapy may address strength, balance, movement habits and functional challenges; it cannot reshape a growing bone by itself, so its role depends on the cause.

When a persistent deformity affects function or needs mechanical correction, an osteotomy can realign a bone by making a planned surgical cut and securing the corrected position. The surgeon will explain the bone involved, recovery plan and possible need for follow-up during growth.

Arrange a medical assessment if bowing is worsening, clearly uneven, painful, associated with limping, or making walking and running difficult. Seek prompt care after an injury if the leg suddenly looks different or cannot bear weight. A child with swelling, fever or significant night pain also needs timely review.

Ask whether the alignment is appropriate for the person’s age, whether both legs are affected equally, and what findings would change the plan. You can also ask how physiotherapy would help, when an osteotomy becomes appropriate, and what follow-up will monitor growth.
