What should you know about mild bow leg?

Bow legs, or genu varum, describe an outward curve of the legs. A mild appearance can be a normal developmental pattern in some young children, but the meaning changes with age and growth. Doctors consider whether the curve is on one or both sides, whether it is changing, and whether walking is painful or uneven.

Arrange an assessment if the appearance is pronounced, clearly one-sided, worsening, associated with limp or pain, or persists beyond the expected growth pattern. Bring information about when you first noticed it and whether a parent or clinician has measured the alignment. Examination may include gait assessment and, when appropriate, standing imaging.

Most people do not need to alter normal activity solely because of a mild appearance. Supportive footwear should be comfortable rather than corrective without advice. [Paediatric Physiotherapy](/treatments/physiotherapy-and-rehabilitation/paediatric-physiotherapy/) may help when strength, balance, or movement habits affect function. If bone alignment is causing significant symptoms or mechanical problems, an orthopaedic specialist may discuss [Osteotomy](/treatments/reconstructive-orthopedic-surgery/osteotomy/).

Seek prompt medical review if symptoms are severe, worsening, clearly one-sided when that is unexpected, or accompanied by marked weakness, numbness, fever, a new deformity, or inability to use the affected limb. Urgent assessment is appropriate after significant trauma or when normal function suddenly changes.

Ask what finding supports the diagnosis, which activities should be modified, what signs should trigger earlier review, and how progress will be measured. Discuss medicines, exercises, and any need for imaging or specialist referral in the context of your symptoms.
