Flat foot reconstruction surgery
Flat foot reconstruction surgery aims to rebuild the arch of the foot, reduce pain and improve walking when insoles and other treatments have not helped.
Flat foot reconstruction surgery overview
The arch of the foot can flatten because of a deformity, damage to the tendon that supports the arch or arthritis around the heel. Surgery may be recommended when the foot is painful and non-surgical treatments, such as insoles and physiotherapy, have not provided enough relief. The operation is tailored to the cause and shape of your flat foot. Your specialist will explain which procedures you need and what they are designed to achieve.
How is surgery carried out?
The procedure is usually performed under a general anaesthetic, with an injection in the foot to help control pain afterwards. Most people stay in hospital overnight.
Surgery commonly involves replacing the damaged tendon on the inside of the foot with another tendon. The heel bone may also be cut, repositioned and held with a screw to improve support beneath the arch. In some cases, a plate is placed across the top of the foot to help increase the arch.
Are there any risks?
Possible risks include:
- Infection
- Numbness caused by irritation or damage to a nearby nerve
- Continued pain or other symptoms
- Metalwork becoming uncomfortable beneath the skin
- A blood clot in the leg, known as deep vein thrombosis (DVT)
Your specialist will discuss the risks that apply to your operation before surgery.

Recovery from flat foot reconstruction surgery
Protecting the reconstruction
You will normally wear a cast or boot and avoid putting weight through the operated foot. Keep your foot raised as much as possible to reduce swelling.
Returning to your own shoes
Your foot will be X-rayed and, if healing is progressing well, you can begin putting weight through it in your own shoes with an insole or brace.
Rebuilding strength and activity
Walking and strength will gradually improve. Many people return to a good level of activity and sport within six months, with swelling and function continuing to improve for up to a year.
Working with foot and ankle professionals and teams
Our foot and ankle specialists support professional athletes, sports teams, active individuals and people whose work places high demands on their feet and ankles. Working closely with radiologists, physiotherapists and the wider multidisciplinary team, they provide coordinated care from diagnosis through to rehabilitation, helping each person return safely to sport, work or everyday activities.
The same specialist expertise and collaborative approach are available to every patient, whatever your activity level or recovery goals.

How to pay
We offer flexible options depending on how you choose to access care at Fortius. Whichever option you choose, we’ll help make the process clear and straightforward from the start.

Private medical insurance
If your care is covered by private medical insurance, we’ll usually invoice your insurer directly. Please check your policy in advance and request an authorisation code if your insurer requires one. You’ll be responsible for paying any policy excess or costs that aren’t covered by your insurance.

Paying for yourself
You don’t need private medical insurance to access care at Fortius. If you’re paying for your own treatment, our team will explain the costs clearly and provide a personalised quote before you decide whether to go ahead.
Flat foot reconstruction surgery FAQs
You must be out of your cast or boot and able to perform an emergency stop safely. This usually takes at least eight weeks. Ask your specialist and check with your insurer before driving.
You may be able to return to desk-based work after around three weeks if you can travel safely and keep your foot raised. Manual work may require up to 12 weeks away.
Most people can return to a good level of activity and sport within around six months. Your physiotherapist will help you return gradually, and you may be advised to wear supportive insoles.
