Adults who were treated for clubfoot as children may experience ankle and foot issues decades after their initial treatment concluded. Understanding clubfoot ankle problems in adults — what causes them, how they present, and what can be done — helps you seek the right help at the right time rather than simply living with discomfort.
Why Do Ankle Problems Develop Later?
Even with successful childhood treatment, a clubfoot-treated ankle and foot differ from a never-affected ankle in several ways that can lead to problems in adulthood:
- Altered joint mechanics — the bones and cartilage surfaces in a corrected clubfoot may not be perfectly aligned, leading to asymmetric loading across the joint. Over decades, this uneven wear can produce early degenerative changes
- Reduced range of motion — most adults with treated clubfoot have slightly less ankle dorsiflexion and plantarflexion than unaffected adults. This stiffness compounds gradually with age
- Calf muscle weakness — the calf on the treated side is typically smaller and weaker, affecting push-off power, endurance, and the dynamic stability of the ankle
- Scar tissue — adults who had extensive surgery (posteromedial release, which was standard before the Ponseti method was adopted in the UK) may have significant scar tissue restricting movement and contributing to pain
- Compensatory patterns — years of subtly altered gait can place stress on the knee, hip, and lower back, creating a chain of musculoskeletal issues
Common Adult Ankle Problems After Clubfoot
Ankle Stiffness
The most universal finding. Almost all adults with treated clubfoot report some degree of ankle stiffness, ranging from barely noticeable to functionally limiting. Stiffness tends to be:
- Worse in the morning or after sitting for long periods
- Improved by movement and gentle warming up
- Exacerbated by cold weather
- More pronounced in dorsiflexion (pulling the foot up) than plantarflexion (pointing down)
Management:
- Daily ankle stretching exercises — 5 minutes morning and evening can significantly improve functional range
- Regular movement — avoiding prolonged periods of immobility
- Swimming — the warm water and kicking movements naturally mobilise the ankle
- Supportive footwear — shoes with a slight heel lift (1–2cm) reduce the demand on dorsiflexion during walking
Ankle Pain
Pain in and around the ankle is reported by approximately 20–40% of adults with treated clubfoot. The nature of the pain varies:
- Aching after activity — the most common pattern. Dull pain after walking, standing, or exercise, easing with rest. This often reflects early degenerative changes or joint irritation from altered mechanics
- Sharp pain with specific movements — may indicate impingement (bone or soft tissue being pinched during movement). Anterior impingement (front of the ankle) is particularly common in dorsiflexion-limited ankles
- Pain around the scar — adults with surgical scars from childhood operations may experience tenderness, tightness, or shooting pains around scar tissue, especially in cold weather
- Lateral ankle pain — pain on the outside of the ankle, sometimes related to habitual walking on the outer border of the foot (residual supination)

Early Osteoarthritis
Research suggests that adults with treated clubfoot develop ankle osteoarthritis earlier and more frequently than the general population. A study from the University of Iowa followed Ponseti-treated patients for 30+ years and found that while most had excellent function, radiographic (X-ray) signs of degenerative change were present in approximately 40% by age 30 — though many of these were asymptomatic.
For adults treated with the older surgical methods (pre-Ponseti), the rates are higher. Posteromedial release surgery disrupts the blood supply to some foot bones (particularly the talus), accelerating cartilage degradation.
Key points about clubfoot-related osteoarthritis:
- X-ray changes don't always correlate with symptoms — some people with significant radiographic changes are pain-free
- Weight management is genuinely important — every kilogram of excess body weight adds approximately 3kg of force to the ankle joint during walking
- Low-impact exercise (swimming, cycling, yoga) maintains fitness without accelerating joint wear
- Anti-inflammatory medication (ibuprofen, naproxen) can manage flare-ups, but long-term daily use should be discussed with your GP
Ankle Instability
Some adults with treated clubfoot experience recurrent ankle sprains or a feeling of the ankle "giving way." This can result from:
- Weakened lateral ligaments (from previous sprains or altered anatomy)
- Calf weakness affecting dynamic stability
- Reduced proprioception (the brain's ability to sense joint position) in the treated foot
Management includes:
- Ankle-strengthening exercises — wobble board work, single-leg standing, calf raises
- Ankle braces or supports — available from pharmacies, worn during sport or activity
- Physiotherapy — a targeted programme to improve proprioception and strength
- In persistent cases, surgical ligament reconstruction may be considered
Flat Foot or Overcorrection
A minority of adults with treated clubfoot develop a flat foot (pes planus) or even a foot that has been overcorrected in the opposite direction to the original deformity. This is more common in adults who had extensive surgical correction as children. Symptoms include:
- Pain along the inner ankle (posterior tibial tendon area)
- Arch collapse during standing
- Difficulty finding shoes that fit comfortably
- Fatigue during walking
Custom orthotic insoles (available through NHS podiatry) can support the arch and redistribute pressure. In severe cases, surgical reconstruction may be considered.
Metatarsalgia and Forefoot Pain
Pain under the ball of the foot (metatarsalgia) occurs when the forefoot bears uneven pressure — common in feet with residual adductus (forefoot curving inward) or cavus (high arch). Management:
- Metatarsal pad insoles — available over the counter or custom-made through podiatry
- Shoes with a wide toe box and good cushioning
- Avoiding high heels, which increase forefoot pressure
- Physiotherapy for foot intrinsic muscle strengthening
Getting Help Through the NHS
Many adults with childhood clubfoot have been discharged from orthopaedic follow-up and don't know where to turn when problems develop. The pathway:
Step 1: See Your GP
Explain your clubfoot history and current symptoms. Ask for referral to:
- Adult orthopaedics — specifically a foot and ankle specialist, not a general orthopaedic surgeon. Clubfoot is a specialist area, and the nuances of managing adult sequelae require specific expertise
- Musculoskeletal physiotherapy — for stiffness, weakness, and pain management. You may be able to self-refer to MSK physio in your area without needing a GP referral
- Podiatry — for insole prescriptions, gait analysis, and biomechanical assessment. NHS podiatry referral criteria vary by area
Step 2: Investigations
Your specialist may request:
- X-rays — weight-bearing ankle and foot X-rays to assess joint alignment and degenerative changes
- MRI — if soft tissue pathology (tendon damage, ligament injury, impingement) is suspected
- Gait analysis — available at some specialist centres, providing detailed information about how you walk and where abnormal forces are being generated
Step 3: Treatment Plan
Treatment depends on the specific problem but typically involves a combination of:
- Physiotherapy — exercise programme, manual therapy, and education
- Orthotics — custom insoles or ankle-foot orthoses
- Footwear advice — appropriate shoe types, modifications
- Pain management — medication, injection therapy, or onward referral to a pain clinic
- Surgery — only when conservative measures have failed and there is a clear surgical target
Exercise and Activity for Adults with Clubfoot Ankles
Staying active is one of the best things you can do for clubfoot-affected ankles. The right exercise maintains joint mobility, strengthens supporting muscles, and manages weight. Recommended activities:
- Swimming — the gold standard for clubfoot ankles. Non-weight-bearing, promotes range of motion, builds strength
- Cycling — low impact, good cardiovascular exercise, adjustable resistance
- Yoga and Pilates — excellent for flexibility, core strength, and balance. Modify poses that require deep ankle dorsiflexion
- Walking — in supportive shoes, on even surfaces. Build up distance gradually
- Strength training — calf raises, ankle dorsiflexion against resistance bands, single-leg balance work
Activities that may require modification:
- Running — high impact through the ankle. If you enjoy running, supportive shoes, softer surfaces (trail/grass), and gradual mileage increases reduce injury risk
- Football and court sports — lateral movements stress the ankle. Ankle braces and thorough warm-up help
- Hiking on uneven terrain — use walking poles for stability and choose supportive ankle boots

Footwear for Adult Clubfoot Ankles
Appropriate footwear makes a measurable difference to comfort and function:
- Firm heel counter — the back of the shoe should hold the heel securely
- Cushioned sole — shock absorption reduces impact forces on the ankle
- Slight heel elevation — 1–2cm reduces the demand on limited dorsiflexion during walking
- Wide fit options — clubfoot-treated feet may be wider than average. New Balance, Brooks, and ASICS offer wider fittings
- Removable insoles — allows custom orthotics to be fitted inside the shoe
- Avoid completely flat shoes (ballet pumps, plimsolls) — these demand maximum ankle dorsiflexion and offer no support
- Different sizes — if your feet are significantly different sizes, some retailers sell odd pairs. Online services like Odd Shoe Finder facilitate this
Frequently Asked Questions
Q: Is it normal to have ankle pain after childhood clubfoot treatment?
A: A degree of stiffness and occasional aching is common and not necessarily a sign of a serious problem. However, persistent or worsening pain, pain that disrupts daily activities, or pain that doesn't respond to simple measures like rest and anti-inflammatories should be assessed by a foot and ankle specialist. Don't assume that pain is something you just have to live with.
Q: I was treated with surgery before Ponseti — are my ankle problems worse?
A: Adults who had posteromedial release surgery (PMR) as children do tend to experience more long-term complications than those treated with the Ponseti method. PMR disrupts more of the ankle's soft tissue structures and can affect blood supply to the talus, leading to earlier degenerative changes. If you had surgical treatment, regular monitoring by a foot and ankle specialist is particularly worthwhile.
Q: Can I get a referral to a clubfoot specialist as an adult?
A: Yes. While clubfoot is primarily managed by paediatric orthopaedic teams, adults with clubfoot-related problems should be seen by an adult foot and ankle orthopaedic surgeon. Ask your GP for a specific referral to foot and ankle rather than general orthopaedics. Some specialist centres have clinics specifically for young adults transitioning from paediatric to adult care.
Q: Will I need surgery as an adult?
A: Most adults with treated clubfoot do not need surgery. Conservative measures (physiotherapy, orthotics, footwear, pain management) are effective for the majority. Surgery is considered when conservative treatment fails and there is a specific, correctable problem — such as impingement requiring debridement, tendon dysfunction requiring repair, or advanced arthritis requiring fusion. See our guide to adult clubfoot surgery for more detail.
Q: Does clubfoot-related ankle arthritis qualify for disability benefits?
A: If ankle problems from childhood clubfoot significantly affect your ability to work or carry out daily activities, you may be eligible for Personal Independence Payment (PIP) or other disability benefits. The assessment focuses on functional limitation rather than diagnosis. See our clubfoot and disability guide for eligibility criteria and application advice.
