Bow leg correction: assessment and treatment choices

Some children need observation as alignment develops, whereas an abnormal growth pattern may require specialist management. In adults, rehabilitation can improve function but fixed bone alignment generally requires a bone procedure if true structural correction is needed.

For one person, treatment may aim to ease pain and improve control without making the legs look straight. For another, the priority may be shifting the body's weight-bearing line across the knee to reduce uneven joint loading. Appearance, function and mechanical alignment are related but are not interchangeable outcomes.

The curve may arise in the thigh bone, shin bone or both, so treatment must target the correct site. Examination of gait and joint movement, together with standing alignment images when appropriate, helps define the plan.

Begin with an orthopaedic assessment if the bowing is painful, progressive or affecting walking. Bring details of previous fractures, operations and treatments. Physiotherapy may address strength, balance, mobility and activity tolerance, even though exercise does not remodel a fixed adult bone curve.

When operative realignment is being considered, discuss the intended change, the bone involved, recovery demands and alternatives. Osteotomy changes alignment by cutting and repositioning bone; suitability depends on the individual limb and joint rather than appearance alone.

A gradual curve without pain can be discussed at a routine appointment, particularly if it is changing. Seek earlier evaluation for persistent knee or hip pain, limping, repeated instability, unequal leg alignment or reduced ability to manage normal activities.

Following an injury or procedure, obtain urgent help for a newly misshapen limb, inability to bear weight, escalating swelling, severe pain, numbness or colour change in the foot.

Ask what is driving your symptoms, whether the deformity is fixed, and which outcome the proposed care is designed to improve. For surgery, request a clear explanation of fixation, weight-bearing restrictions, rehabilitation, possible complications and how the alignment will be checked afterward.
