Foot & ankle · UK
Flat feet surgery in the UK, by a consultant foot & ankle surgeon.
A proper reconstruction — osteotomy, tendon transfer or fusion — by a BOFAS-affiliated foot and ankle consultant. Non-surgical care always on the table first, and honest staging based on the modern 2020 PCFD classification.
Why patients choose us
- 01
A consultant foot & ankle surgeon, in theatre
A named BOFAS-affiliated foot and ankle surgeon in a proper theatre — not a podiatry room and not a training list.
- 02
Non-surgical options exhausted first
Most flat feet don’t need surgery. Orthotics, physio and a boot come first — we say so before you commit to an osteotomy.
- 03
Independent, and free
We are paid by no clinic, so the recommendation is impartial and costs you nothing.

The problem
The right surgeon, the right stage, the right operation.
Flat feet are staged poorly and operated on too early or too late. We line up the right BOFAS-affiliated foot and ankle consultant, the right imaging, and the right conversation about whether surgery is even needed.
-
Not sure it is needed?
Most flat feet don’t need surgery — three to six months of orthotics, boot and physio come first. We’ll say so plainly.
-
Worried about staging?
We use the modern 2020 PCFD classification, not the outdated single-word “flatfoot” label, so the operation actually matches the disease.
-
Want it done properly?
A named BOFAS-affiliated consultant, weight-bearing X-rays and MRI in advance, and honest talk about non-union, hardware and recovery time.

Before
You tell us what is going on
A short, confidential form. Symptoms, how long, whether it’s an adult acquired deformity, a child’s foot, or a rigid coalition.
- 02
Before
We come back with a recommendation
Within one working day: the right surgeon, whether conservative care should come first, an indicative price. If surgery isn’t the right step, we say so.
- 03
Before
We arrange the appointment
Weight-bearing X-rays and MRI are set up beforehand. Any blood-thinning medication is reviewed with the team.
- 04
On the day
Arrival at the clinic
Arrival, consent and a chat with the surgeon and anaesthetist. Almost always GA or regional block — day case or one-night stay.
- 05
On the day
The procedure itself
90 minutes to 3 hours in a proper theatre — osteotomies, tendon transfer and, where needed, joint fusion. Cast or boot applied.
- 06
On the day
Home the same day or next morning
Non-weight-bearing on crutches, written aftercare, and home. Someone needs to collect you and stay the first night.
- 07
After
Recovery and review
6–12 weeks non-weight-bearing, gradual return, physio to 6 months, sport by 6–9 months. Reviews arranged throughout.
Typical end-to-end: 3–4 weeks from enquiry to surgery. Full recovery: 6–12 months.
When it helps
When flat feet surgery is the right step.
The situations we see most, plus the one red flag that means an emergency rather than an appointment.
-
Adult acquired flatfoot (PCFD)
Progressive collapsing foot deformity — the arch drops in mid-life, the heel drifts outwards, walking distance shortens.
-
Posterior tibial tendon dysfunction
The tendon that holds up the arch fails. Pain behind the inner ankle, then a visible flattening — the commonest cause of adult PCFD.
-
Failed single-heel-raise test
You can’t rise onto the ball of one foot with the heel inverting — a hallmark of PTT dysfunction and Deland stage II disease.
-
“Too many toes” sign
Seen from behind: three or more toes visible lateral to the ankle — forefoot abduction, a sign of stage IIB deformity.
-
Rigid flatfoot from tarsal coalition
A congenital bar between hindfoot bones — calcaneonavicular or talocalcaneal. Painful adolescent flatfoot that won’t correct.
-
Painful paediatric flexible flatfoot
Most flexible flatfoot in children is painless and needs no treatment. Surgery is reserved for the small painful, refractory group.
-
Stage III/IV with subtalar arthritis
A rigid, arthritic hindfoot or valgus ankle tilt — beyond soft-tissue repair, into the territory of fusion or replacement.
-
Red flag: sudden collapse + severe pain
Acute PTT rupture or a Charcot foot in a diabetic — same-day orthopaedic assessment, not a routine clinic booking.
Procedure options
One operation is rarely enough — reconstructions are combinations.
What each option on the table actually involves — and which stage of PCFD it fits.
-
Orthotics & physio (always first)
Custom insole, medial post, Richie brace or UCBL, plus PTT strengthening and calf stretching. 3–6 months before surgery is considered.
-
MDCO + FDL transfer
Medial displacement calcaneal osteotomy + flexor digitorum longus tendon transfer to the navicular. Workhorse for stage IIA disease.
-
Lateral column lengthening (Evans)
Adds length to the outside of the foot to correct forefoot abduction. Added to MDCO/FDL for stage IIB disease.
-
Cotton osteotomy
A small opening wedge in the medial cuneiform to plantarflex a lifted first ray — a common add-on for residual forefoot varus.
-
Gastrocnemius recession (Strayer)
Releases a tight calf that pulls the hindfoot into valgus. Often done at the same sitting when equinus is present.
-
Spring ligament reconstruction
Repairs or augments the incompetent spring ligament — the sling that holds the head of the talus up on the medial side.
-
Triple arthrodesis (stage III)
Fusion of subtalar, talonavicular and calcaneocuboid joints. Definitive for a rigid, arthritic flatfoot. Modern modifications preserve some motion.
-
Stage IV: TAR, ankle fusion, pantalar
When the ankle joint has tilted into valgus and worn out — total ankle replacement, tibiotalar fusion or pantalar fusion depending on cartilage.
Our vetted UK network
A small panel of foot & ankle consultants, we picked them.
BOFAS-affiliated consultant foot and ankle surgeons across London, the South East and the North. Not listed publicly — introductions are made privately, once we understand your case.
Selection criteria
How we choose every surgeon in our network.
-
BOFAS-affiliated consultant foot and ankle surgeons, not trainees or general orthopaedic surgeons
-
Weight-bearing X-ray (Meary angle, calcaneal pitch) and MRI available in-house
-
Non-surgical pathway (orthotics, boot, physio) offered before osteotomies discussed
-
Both joint-sparing (osteotomy, tendon transfer) and joint-sacrificing (fusion) techniques on offer
Safety and recovery
What to expect afterwards — honestly.
Flat feet surgery is a substantial reconstruction with a long recovery. The things worth planning are non-weight-bearing logistics, the risk of non-union in smokers and diabetics, and the small chance of a second operation to remove hardware.
-
Non-weight-bearing for 6–12 weeks
Osteotomies and tendon transfers need bone and soft tissue to knit. That means crutches or a knee scooter for 6–12 weeks — plan work, stairs and driving around it.
-
Non-union is uncommon but real
Around 5–10% of osteotomies and fusions fail to knit first time — higher in smokers, diabetics and those on steroids. Stop smoking well before surgery.
-
Hardware sometimes comes out
Screws and plates are usually left in, but 10–20% of patients need a second operation to remove hardware that is prominent or uncomfortable.
-
Sural nerve numbness is possible
Lateral column lengthening runs near the sural nerve. A patch of numbness on the outside of the foot can result — usually settles, sometimes permanent.
-
Adjacent joint arthritis, long term
Triple arthrodesis stiffens the hindfoot and loads the ankle above and the midfoot below. Over decades this can drive adjacent joint arthritis.
-
Recurrence and revision
A minority of feet under-correct or drift back. A staged revision, added Cotton osteotomy or conversion to fusion is sometimes needed.
-
DVT, wound and infection risks
Deep vein thrombosis, wound edge problems and infection are the general surgical risks of prolonged non-weight-bearing lower-limb surgery.
-
Paediatric flexible flatfoot rarely needs surgery
Most children with painless flexible flatfoot grow up normally. Surgery — including arthroereisis — is a last resort in painful, refractory cases.
-
Red flags
A cold, blue or numb foot, calf swelling, fever or spreading wound redness after surgery are not normal — call the team or A&E the same day.
Reading your operation note
Your operation note in four parts. Read the last one first.
Whichever combination was performed, the note the surgeon sends you keeps to the same shape.
A quiet reminder
Surgical language is precise and can read coldly — we translate it for you.
If you would like us to talk you through the note before your review, just ask.

Weight-bearing plan and physio timing
Read this first: how long non-weight-bearing, when the boot is swapped for a shoe, when physio begins, and when sport is realistic.
Recognised by major UK insurers
Cover for flat feet surgery varies by insurer and by indication — usually funded when symptomatic PCFD has failed conservative care, and case-by-case for adolescents. We confirm cover before booking.
Frequently asked
Everything we get asked about flat feet surgery.
Quick answers on diagnosis, staging, cost, recovery time and whether children should be operated on.
-
Do all flat feet need surgery?
No. The great majority don’t. Painless flexible flatfoot in a child needs no treatment. Adult PCFD is managed for 3–6 months with orthotics, a boot, physio and NSAIDs first — surgery is reserved for those who fail conservative care or who have already progressed to a fixed deformity.
-
What is PCFD, and how is it different from AAFD?
Progressive collapsing foot deformity (PCFD) is the modern 2020 name for what used to be called adult acquired flatfoot deformity (AAFD). The Deland 2020 classification replaces the older Johnson-Strom staging and describes the deformity in the flexible foot (stage II), rigid arthritic hindfoot (stage III) and valgus ankle (stage IV).
-
How is the diagnosis made?
By a foot and ankle surgeon: loss of the medial arch on standing, hindfoot valgus, the “too many toes” sign, and a failed single-heel-raise test. Confirmed with weight-bearing X-rays (Meary angle, calcaneal pitch, talonavicular uncoverage) and an MRI to assess the posterior tibial tendon, spring ligament and joint surfaces.
-
What does the surgery actually involve for stage II PCFD?
Most stage IIA feet have an MDCO (medial displacement calcaneal osteotomy) plus an FDL tendon transfer to replace the failed PTT, sometimes with a spring ligament repair. Stage IIB adds a lateral column lengthening (Evans). A Cotton osteotomy and gastrocnemius recession are common add-ons.
-
What is the recovery like?
6–12 weeks non-weight-bearing in a cast or boot on crutches, gradual weight-bearing weeks 6–12, physio out to 6 months, back to sport at 6–9 months and full recovery at around 12 months. Triple arthrodesis is longer and stiffer.
-
What are the main risks?
Non-union of an osteotomy or fusion (5–10%, higher in smokers and diabetics), hardware discomfort needing removal (10–20%), sural nerve numbness after lateral column work, lateral column overload after MDCO, DVT, wound problems, infection, over- or under-correction, and — long term after a triple arthrodesis — adjacent joint arthritis.
-
How much does flat foot surgery cost privately in the UK?
Roughly £8,000–£12,000 for MDCO plus FDL transfer, £10,000–£14,000 with a lateral column lengthening added, and £12,000–£16,000 for a triple arthrodesis. Orthotics and physio are much cheaper — always tried first. NHS treatment is available on the BOFAS pathway when conservative care fails.
-
Should children have surgery for flat feet?
Almost never. Painless flexible paediatric flatfoot is a normal variant that usually resolves. Painful, refractory paediatric flatfoot — or a rigid flatfoot from a tarsal coalition — is different, and may warrant coalition resection or, in selected centres, a subtalar arthroereisis (calcaneo-stop) implant. This is a specialist decision.
