Bow legs in older age: joint changes, mobility and care

Assessment is worthwhile when the shape changes, pain grows, or mobility declines. Care focuses on comfort, safe movement, independence and joint health; visible alignment is only one part of the decision.

Genu varum places the knees apart when the ankles are together. This alignment can direct more load through one side of the knee. Conversely, uneven loss of joint space may make a previously mild curve appear stronger, so the shape and the joint can influence each other.

Symptoms can include pain during standing or walking, stiffness after rest, swelling, reduced knee movement and a sense that the leg is less steady. Similar complaints can have other causes, and an examination helps identify whether the knee, hip, ankle, nerves or circulation need attention.

A clinician or physiotherapist can review walking, lower-limb strength, balance, footwear and the activities that trigger pain. A personalised programme may build leg strength, practise safer transfers, improve confidence on uneven ground and pace demanding tasks. A suitable walking aid can improve stability when it is fitted and taught correctly.

Medication and joint treatments require an individual medical review because other health conditions and medicines matter. If symptoms remain severe and imaging shows a correctable alignment problem, an orthopaedic surgeon can explain whether osteotomy or another surgical approach fits the joint condition and overall health.

Schedule a review for increasing bowing, ongoing pain, repeated swelling, new instability, falls, or shrinking walking distance. A knee that catches or will not fully bend or straighten also needs assessment, especially when it disrupts sleep or basic daily tasks.

Seek urgent care for a hot swollen joint with fever, sudden inability to bear weight, a newly deformed leg after a fall, or new weakness or numbness. A cold, pale or blue foot is another reason for immediate medical evaluation.

Explain which tasks have become difficult and ask what is driving the change in alignment. Discuss how to strengthen safely, whether a walking aid or footwear adjustment would help, what imaging could add, and how each treatment option might affect independence and recovery.
