Understanding the Bow-Leg Position

Clinicians call this alignment genu varum. It is assessed in a relaxed, natural stance because deliberately rotating the hips, turning the feet or forcing the ankles together can exaggerate or conceal the apparent curve.

The visible gap between the knees is only one part of alignment. Hip rotation, the shape of the femur and tibia, knee-joint orientation, ankle position and the direction of the feet can all affect how the legs look from the front.

Static posture does not show how the limb manages load. During walking, an examiner observes the direction of the kneecaps and feet, side-to-side movement at the knee, stride pattern and balance. This separates a flexible posture from a more fixed bony alignment and identifies functional strain.

Stand comfortably on a level surface with weight shared between both feet, then notice whether the bowing is similar on each side. Do not repeatedly press the knees inward or use improvised straps, braces or shoe wedges. Those measures may place stress elsewhere and cannot address every cause.

If the position is associated with discomfort or movement difficulty, note which activities bring it on and where symptoms occur. A physiotherapist or orthopaedic clinician can examine joint mobility, muscle capacity, balance and gait before suggesting an appropriate plan.

Seek a routine assessment if the curve becomes more noticeable, differs clearly between the legs, or accompanies recurring knee, hip, ankle or foot symptoms. A limp, knee instability, reduced walking tolerance or difficulty with everyday movement provides further reason to be examined.

Get prompt medical help for sudden deformity after trauma, inability to bear weight, severe swelling, a visibly displaced joint, or new numbness or colour change below an injury. Do not attempt to straighten an injured limb yourself.

Ask whether the alignment arises mainly from bone shape, joint position or rotation, and whether it changes during walking. Other practical questions cover the source of any pain, which activities are suitable, whether rehabilitation could improve function, and how progression will be recognised.
