Bow-shaped legs in adults

Some adults have had the shape since childhood without major difficulty. In others, increasing varus alignment shifts more load toward the inner side of the knee and may occur alongside pain, stiffness or reduced walking tolerance. The visible shape does not establish the cause or show how healthy the joint is.

An orthopaedic examination considers when the bowing began, whether it has progressed, where discomfort occurs and how it affects work, exercise and stairs. The clinician checks hip, knee and ankle movement, ligament stability, limb rotation, muscle function and walking mechanics.

Standing X-rays may be used to see joint surfaces and measure the load-bearing line through the leg. This can show whether the alignment comes mainly from the thighbone, shinbone or joint. Treatment decisions are based on symptoms, examination, structural findings and personal activity goals together.

Choose activities that remain comfortable and increase their demands gradually. Strengthening the hips and thighs, restoring usable joint movement and improving balance can support function, even when the bone alignment itself does not change. Weight management may reduce knee loading when relevant, while a clinician can advise on suitable footwear, supports and pain relief.

If symptoms continue, an orthopaedic specialist can explain whether the main problem is joint irritation, instability or deformity. Surgery is not required solely because legs look bowed; it is considered when the pattern and its effects justify correction or joint treatment.

Make an appointment for persistent or worsening pain, swelling, locking, giving way, a growing difference between the legs, or loss of normal walking ability. New bowing in adulthood and change following a fracture should also be assessed rather than attributed to ageing alone.

Urgent evaluation is needed after injury when weight bearing is impossible, the knee or leg looks newly deformed, or numbness, weakness, marked swelling, or a cold pale foot develops.

Ask where the alignment originates, whether joint wear or an old injury contributes, and which options target pain versus structure. Discuss how each choice could affect mobility, work and preferred activities, and agree on the signs that would mean the plan should be reconsidered.
