Key facts

Foot arthritis at a glance.

The essentials, in plain English - what it is, where it strikes, and how UK clinicians approach it.

  • What it is

    Arthritis affecting joints of the foot - the umbrella covers osteoarthritis, inflammatory arthritis, crystal disease and rarer causes.

  • Common patterns

    First MTP joint (big toe), midfoot and subtalar joints for osteoarthritis; forefoot and MTPs for rheumatoid; big toe for gout.

  • Symptoms

    Joint pain, stiffness, swelling, deformity and difficulty walking - the pattern often points to the cause.

  • Diagnosis

    A structured history plus examination, weight-bearing X-rays, inflammatory markers and, when needed, joint aspiration.

  • Emergency to know

    A hot, red, exquisitely tender single joint with fever is septic arthritis until proven otherwise - same-day assessment.

  • Related guides

    See our pages on foot and ankle osteoarthritis, arthritis (overview), gout and hand arthritis for wider context.

Why this guide matters

The cause changes the plan.

Osteoarthritis, rheumatoid, gout and psoriatic arthritis all cause a painful foot - but the treatments are very different. Getting the label right matters.

  • Pattern points to cause

    One big toe or many joints, symmetrical or asymmetrical, morning stiffness or activity pain - the pattern usually names the disease.

  • Early inflammatory care wins

    Rheumatoid and psoriatic arthritis do far better when disease-modifying drugs are started early - see rheumatology sooner rather than later.

  • Modern surgery has options

    For end-stage disease, fusion, cheilectomy and total ankle replacement all have a place - see our foot and ankle osteoarthritis guide.

Types

The main kinds of foot arthritis.

A quick tour of the causes UK clinicians see most often - and the rarer ones worth naming.

  • Osteoarthritis

    Degenerative or post-traumatic joint wear - most often the 1st MTP (hallux rigidus), midfoot and subtalar joints. See our foot and ankle osteoarthritis page for detail.

  • Rheumatoid arthritis

    Autoimmune, typically symmetrical, forefoot-heavy - drives hallux valgus, hammer or claw toes and rheumatoid nodules. See our arthritis overview.

  • Gout

    Urate crystal disease - podagra (acute inflammation of the 1st MTP) is classic, with tophi in longstanding disease. See our dedicated gout page.

  • CPPD / pseudogout

    Calcium pyrophosphate crystal disease - can mimic gout with acute painful joints and chondrocalcinosis on X-ray.

  • Psoriatic arthritis

    Often DIP joints, with dactylitis (sausage toes), nail pitting and enthesitis - part of the spondyloarthritis family.

  • Reactive arthritis

    Follows a gastrointestinal or urogenital infection - asymmetrical lower-limb joint pain, often with enthesitis and dactylitis.

  • Septic arthritis

    An infected joint - hot, red, exquisitely tender, often with fever. A medical emergency needing joint aspiration and antibiotics.

  • Haemochromatosis

    Iron overload can cause a distinctive small-joint arthropathy affecting the MTPs alongside other joints.

  • Haemophilia

    Recurrent joint bleeds can cause a progressive haemophilic arthropathy - factor replacement and rehab are central.

How the diagnosis is made

From first symptoms to a clear plan.

The steps a UK GP, rheumatologist or foot and ankle specialist will normally follow, in order - so you know what to expect and why.

  1. 01

    Assessing

    History and pattern

    When did it start, how many joints, symmetrical or one-sided, better or worse with rest - the pattern often names the disease.

  2. 02

    Assessing

    Focused examination

    Which joints are swollen or tender, deformities (hallux valgus, hammer toes), gait, skin changes and nails.

  3. 03

    Assessing

    Inflammatory features

    Prolonged morning stiffness, warmth, redness and multi-joint involvement raise the chance of inflammatory arthritis.

  4. 04

    Confirming

    Blood tests

    CRP and ESR for inflammation, rheumatoid factor and anti-CCP for rheumatoid, urate for gout, HLA-B27 for spondyloarthritis when indicated.

  5. 05

    Confirming

    Imaging

    Weight-bearing foot X-rays first; ultrasound for synovitis, tophi or effusions; MRI for early inflammatory disease or unclear cases.

  6. 06

    Confirming

    Joint aspiration

    Reserved for suspected septic arthritis or crystal disease - fluid is examined for cells, crystals and organisms.

  7. 07

    Onward

    Specialist referral

    Rheumatology for inflammatory or crystal disease, foot and ankle orthopaedics or podiatric surgery for structural damage.

Typical timeline: a first visit to a settled plan within a few weeks in most cases.

Symptoms

What foot arthritis actually looks like.

Pain, stiffness, swelling and deformity - and the specific patterns that point towards particular causes.

  • Big-toe pain (1st MTP)

    Classic for osteoarthritis (hallux rigidus) and gout - the joint is stiff, tender and often visibly swollen.

  • Forefoot pain across MTPs

    Pain and swelling across the ball of the foot is a hallmark of rheumatoid arthritis.

  • Midfoot and subtalar stiffness

    Deep, aching pain in the arch or under the ankle - typical of osteoarthritis or post-traumatic arthritis.

  • Deformity

    Hallux valgus (bunion), hammer or claw toes and rheumatoid nodules can develop as the disease progresses.

  • Nail and skin changes

    Pitted or lifted nails and psoriasis plaques suggest psoriatic arthritis, especially with DIP joint pain.

  • Dactylitis (sausage toe)

    A whole toe swollen and tender points strongly to psoriatic or reactive arthritis.

  • Walking difficulty

    Altered gait, difficulty with shoes and pain when weight-bearing are common across all causes.

  • Red flag - hot, swollen single joint

    A single hot, red, extremely tender joint with fever is septic arthritis until proven otherwise - go to A&E.

Treatment

How foot arthritis is treated in the UK.

A stepped plan - footwear and physio first, then targeted drugs by disease type, and surgery when structure has failed.

  • Footwear and orthotics

    Stiff-soled shoes, rocker soles and custom orthotics can offload painful joints and are often the first practical win.

  • Physiotherapy

    Targeted strengthening, mobility and gait retraining help most causes of foot arthritis.

  • Simple analgesia and topicals

    Paracetamol and topical NSAIDs are a sensible start, escalating to oral NSAIDs if safe.

  • Cortisone injection

    A guided steroid injection into a painful joint can settle inflammation and buy time for other measures.

  • DMARDs for inflammatory disease

    Rheumatoid and psoriatic arthritis need disease-modifying drugs (methotrexate, sulfasalazine) or biologics under rheumatology.

  • Urate-lowering therapy

    Allopurinol or febuxostat prevents gout attacks - started once flares are controlled and continued long-term.

  • Colchicine and NSAIDs for flares

    Short courses of colchicine, NSAIDs or steroids settle acute gout and pseudogout attacks.

  • Foot and ankle surgery

    Cheilectomy, arthrodesis or replacement (including total ankle replacement) is considered when non-surgical care fails.

Red flags

When foot arthritis needs urgent attention.

Most foot arthritis is managed in primary and outpatient care. These are the situations where a specialist opinion is needed quickly.

  • Hot, red, exquisitely tender single joint

    Especially with fever or feeling unwell - septic arthritis is an emergency needing same-day assessment and joint aspiration.

  • Rapid deformity or joint collapse

    Sudden change in shape of the foot, especially in diabetes, can be Charcot arthropathy - needs urgent orthopaedic review.

  • New inflammatory pattern

    Multi-joint pain with prolonged morning stiffness, swelling and fatigue needs prompt rheumatology referral.

  • Dactylitis or enthesitis

    Sausage toes or heel-insertion pain point to spondyloarthritis - early diagnosis changes long-term outcomes.

  • Tophi

    Firm nodules on joints or the ear suggest longstanding gout - urate-lowering therapy is usually indicated.

  • Neurovascular compromise

    Numbness, weakness or cold, pale toes alongside joint pain needs urgent assessment.

  • Ulceration in inflammatory arthritis

    Skin breakdown over rheumatoid nodules or deformed joints risks deep infection - see a specialist promptly.

  • Unexplained weight loss and joint pain

    Systemic features with joint pain deserve early investigation for inflammatory or systemic disease.

  • Failure of first-line care

    Persistent, disabling pain despite footwear, physio and simple analgesia is a signal to escalate.

Living with it

A treatable condition, with a clear ladder.

Four things that make the biggest difference day to day - the right shoes, gentle movement, a bit of weight management and knowing when to step up care.

A quiet reminder

Consistency beats intensity, every time.

Small, steady habits kept up for months do more for a painful foot than a heroic week that doesn’t last.

  1. 01 Shoes

    Get the footwear right

    Stiff soles, a wide toe box and cushioning make more difference than most medicines - a podiatry review is often the highest-value step.

  2. 02 Move

    Keep moving, gently

    Low-impact activity (cycling, swimming, walking) preserves joints and mood. Total rest usually makes stiffness worse.

  3. 03 Weight

    Small weight changes matter

    Each kilogram lost eases the load on every joint below the waist - a modest change pays back daily.

  4. 04 Escalate

    Don’t accept slow decline

    If pain, deformity or walking are worsening, ask for imaging and specialist review - modern care can change the trajectory.

Frequently asked

Everything we get asked about foot arthritis.

Quick answers on causes, diagnosis, red flags and what UK treatment actually looks like.

  • What is foot arthritis?

    It is the umbrella term for arthritis affecting the joints of the foot. The most common causes are osteoarthritis (wear and post-traumatic), rheumatoid arthritis, gout and psoriatic arthritis - each has a typical pattern and its own treatment ladder.

  • Which joints are usually affected?

    Osteoarthritis most often hits the big-toe joint (1st MTP), the midfoot and the subtalar joint. Rheumatoid arthritis typically affects the forefoot and MTP joints symmetrically. Gout classically flares in the big toe (podagra). Psoriatic arthritis often involves the DIP joints and causes dactylitis.

  • How is it diagnosed?

    By history and examination, weight-bearing X-rays, and blood tests (CRP, ESR, rheumatoid factor, anti-CCP, urate, HLA-B27 when indicated). Ultrasound and MRI help in early inflammatory disease, and joint aspiration is used for suspected septic arthritis or crystal disease.

  • Is foot arthritis curable?

    It is not usually curable, but it is very treatable. Inflammatory arthritis controlled early with DMARDs can be effectively suppressed, gout can be prevented with urate-lowering therapy, and osteoarthritis is managed with footwear, physiotherapy, injections and, when needed, surgery.

  • When should I worry about a hot, swollen toe?

    A single hot, red, exquisitely tender joint - especially with fever - should be assessed the same day. Septic arthritis is an emergency, and acute gout, while less dangerous, also needs prompt treatment.

  • What treatments actually help?

    Footwear and orthotics, physiotherapy, weight management and topical or oral NSAIDs help most people. Cortisone injections settle flares. Inflammatory disease is treated with DMARDs and biologics under rheumatology; gout with urate-lowering therapy; advanced structural damage with foot and ankle surgery, including fusion or replacement.
