Ankle arthritis is managed step by step.
- Ankle arthritis is wear of the smooth cartilage that cushions the ankle joint. It most often develops years after an earlier injury.[4][7]
- Care climbs a ladder. Activity changes, supports and medicines come first. An injection may ease pain in selected cases.[1][9]
- Surgery is considered when these no longer cope. Ankle fusion and ankle replacement are the two main operations.[1][9]
- OrthoKinetics is Dr Sean Leo’s professional brand. Clinical consultations and treatment are provided through OrthoSports Orthopaedic & Sports Surgery. Dr Sean Leo is a specialist orthopaedic surgeon who cares for foot and ankle problems.

The ankle is where the leg meets the foot.
The ankle is where the leg meets the foot.
The ankle is where the leg meets the foot.
Two lower-leg bones sit on the talus, the bone beneath them that connects to the foot. Smooth cartilage covers these surfaces so the joint can bear weight with little friction. When that cartilage wears, the joint becomes painful and stiff.
Most ankle arthritis follows an earlier injury.

Most ankle arthritis follows an earlier injury.
Ankle arthritis differs from hip and knee arthritis. It is mostly post-traumatic, which means it follows an earlier injury. Published figures put 56 to 80% of cases after a previous injury, a range across studies rather than one exact number.[4] People are also often younger than those with hip or knee arthritis.[4]
There are three common routes:
- Repeated sprains and long-term instability. Over years, these can damage the cartilage.[14]
- A broken ankle. Arthritis can appear years after a fracture.[13]
- No single remembered injury. Inflammatory conditions, such as rheumatoid arthritis, can also affect the ankle.[7]
An earlier injury makes arthritis possible, not inevitable. It is not a sign that you did something wrong.
What the research figures mean
One long-term study followed people whose ankle fractures were treated with surgery. Advanced arthritis was reported in 36.3% of them at an average of 18 years.[13] That describes a group who had surgery. It is not a forecast for any one person.
An old ankle injury can matter years later.

You may remember an injury from years ago, such as a sprain that kept giving way or a fracture that healed. It is reasonable to wonder whether it is linked to your ankle now.
It can be. Repeated giving way can damage the joint over time.[14] A fracture that healed can still leave the joint surface wearing years later.[13] Completing rehabilitation after any ankle injury matters, as the ankle ligament tear page explains. An old injury is a risk to understand, not a sentence. For the injuries themselves, see the ankle sprain and ankle fracture pages.

Ankle arthritis often follows a familiar pattern:
- Aching pain in and around the joint, often worse with walking, stairs or longer activity.
- Stiffness, especially after rest or first thing in the morning.
- Swelling that comes with activity and eases with rest.
- Movement that feels less smooth over time.
Symptoms can come and go. More than one ankle problem can feel similar, so symptoms alone cannot confirm arthritis.

There are three main types: arthritis after injury (post-traumatic), wear without one remembered injury (osteoarthritis), and inflammatory arthritis, such as rheumatoid arthritis.[7] The ankle’s alignment and stability are also examined, because they change what treatment can achieve.[1] So does the stage. Keyhole options enter only selectively and earlier. Fusion and replacement belong to the stage where simpler measures have failed.[1][9]
When should an arthritic ankle be assessed
When should an arthritic ankle be assessed
When should an arthritic ankle be assessed?
Many people manage an aching ankle themselves for years. These are reasonable reasons to be assessed:
- Pain, stiffness or swelling that persist or keep returning.
- An ankle that increasingly limits walking, work, stairs or recreation.
- A noticeable change in how the ankle moves.
- Wanting to understand your options before deciding anything.
Safety note: This webpage is not an emergency service. No list on this page can rule out a serious problem remotely. Signs that need urgent help are listed in the final section of this page.
Assessment starts with standing X-rays.
Assessment starts with standing X-rays.
Assessment starts with standing X-rays.
Assessment starts with your story: the injury history, how the ankle behaves and what it limits. The examination then checks movement, alignment and stability, because these change what treatment can offer.[1] The first scan is usually a weight-bearing X-ray, taken while you stand so the joint is seen under the load it actually carries. It comes before any advanced imaging.[1]
What MRI and CT add
MRI and CT are useful for working the problem up.[1] They show the bone beneath the joint and the soft tissues around it in more detail. They are added when they answer a useful question.
Simpler measures come first, and many people do well with them.

Most people with ankle arthritis respond to non-surgical care, at least initially.[9] The ladder runs from simplest to most selective:
- Activity change. Swap high-impact choices for lower-impact ones, and pace yourself.[9]
- Footwear and supports. Cushioned shoes and boots laced above the ankle can help.[10] An ankle-foot orthosis is a structured brace that supports the ankle and foot. It is an effective conservative option.[1]
- Walking aids. A stick can help you walk further comfortably.[10]
- Medicines. Simple painkillers and anti-inflammatory medicines are used, and a combined approach matters.[9][1]
- Weight. Where relevant, this is about load on the joint, not blame.[10]
- An injection in selected cases. A corticosteroid injection into the joint can ease pain for a period.[1] It is sometimes also used to help show where the pain comes from.[11] It is not a cure and does not restore worn cartilage. Other injections, such as hyaluronic acid, did not gain consensus support, so their role is uncertain.[1]
- Exercise and physiotherapy. The specialist panel could not agree on the role of exercise in ankle arthritis.[1] It is a discussion for your situation, not a proven treatment.
Surgery is considered when simpler measures no longer cope.

Surgery is considered when simpler measures no longer cope.
Most people with ankle arthritis never need surgery. It is discussed when simpler measures no longer keep symptoms manageable and the joint is substantially worn. Three ideas exist:
- Keyhole surgery (ankle arthroscopy) uses a small camera and instruments through small cuts. It may help selected earlier-stage problems.[9] The specialist panel did not agree that it treats ankle arthritis itself, so its role is limited.[1]
- Realignment osteotomy repositions bone to shift load away from the worn area. It may relieve symptoms in selected alignment problems.[1]
- Fusion or replacement are the two main operations when the joint is worn out and non-surgical care has failed.[9]
Structure / Patient / Goal
Structure / Patient / Goal
Deciding together
Structure / Patient / Goal
S
Structure: what is affected?
Structure is how much of the joint surface is worn, the ankle’s alignment and stability, and the joints around it.
P
Patient: how does it affect you?
Patient means you as a whole person. Your age, activity, health, work and preferences all shape which options are reasonable.
G
Goal: what are you hoping to return to?
Goal is what “better” means to you, such as walking comfortably, returning to work or recreation, or simply relying on your ankle.
Your plan
No single factor decides treatment alone.
Preserving, fusing and replacing the ankle are different aims.
Preserving, fusing and replacing the ankle are different aims.
Preserving, fusing and replacing the ankle are different aims.
These three paths aim at different things. None is right for everyone.
- Preserving keeps your own joint while managing symptoms, through the ladder above and, in selected alignment problems, a realignment osteotomy.[1] It does not restore worn cartilage.
- Fusing (ankle fusion, or ankle arthrodesis) aims for reliable pain relief by removing the worn joint. The ankle is then stiff, but characteristically more comfortable.[9]
- Replacing (total ankle replacement) aims to keep the joint moving by resurfacing it.[9]
| Fusion | Replacement | |
|---|---|---|
| What it is | The worn surfaces are removed and the bones unite into one.[9] | The worn surfaces are replaced with artificial components.[9] |
| Motion afterwards | The ankle is stiff. The foot’s other joints keep about half of its up-and-down motion.[9] | Studies find better range of motion than after fusion.[3] |
| Durability considerations | About 1 in 10 did not unite in the classic review. Neighbouring joints may carry more stress.[2][6] | Pooled modern data show about 93% implant survival at five years or more. Older designs did less well.[4][2] |
| Typical discussion points | It generally cannot be changed to a replacement later.[11] | Higher complication and reoperation rates than fusion. It suits selected patients.[3][11] |
Head to head. Direct comparisons find no significant difference in overall outcome scores, pain, gait or satisfaction.[3] Replacement shows better function scores and range of motion. Fusion shows lower complication and reoperation rates.[3] No randomised trials exist, so these are observational comparisons.[6]
Who tends to suit which. Replacement generally suits older, lower-demand patients without major deformity or instability. Suitability is assessed individually.[11]
Each operation works in a different way.

Each operation works in a different way.
Fusion removes the worn joint surfaces and fixes the bones together until they unite. It can be done open or with keyhole assistance. Both are established approaches.[1]
Replacement resurfaces the joint with artificial components. Implants come in fixed-bearing and mobile-bearing designs. No one yet knows whether one is better.[9] Techniques vary, and nothing here is a surgical plan.
Recovery after either operation is staged and protected.

Recovery
Recovery after either operation is staged and protected.
Recovery is measured in months. It is judged by how healing and function progress, not by a fixed date.
After fusion, typical UK-service guidance describes about three months in a cast or boot, with weight returning gradually as X-rays confirm healing. Exact plans vary by technique, surgeon and patient, and your treating team sets yours.[9][10][11] After replacement, one NHS trust’s leaflet describes a plaster splint after the operation, no weight on the leg for 2 to 3 weeks, a walker boot from about 2 weeks and full weight bearing by 6 to 8 weeks, with improvement over about twelve months.[15] Plans differ between services.
The typical fusion timetable in UK-service guidance
- Hospital stay: around 1 to 3 days.[12][11]
- Weight: none on the ankle for roughly the first 4 to 6 weeks, then progressive loading.[10][9]
- X-ray checks: around 3 months.[11]
These are typical UK plans, not a Singapore timetable.
The foot and ankle surgery recovery page explains recovery stage by stage.
Risks and complications
Risks and complications
Risks and complications
Both operations carry real limits.
Fusion. The bones may not unite. In the classic systematic review, about 10% did not unite and about 9% needed further surgery, mostly for that reason.[2] Studies varied a lot, so these are a guide. The ankle is permanently stiff and walking mechanics change. Neighbouring joints carry more stress, and arthritis can develop in them over time, a recognised concern rather than a certainty.[6] A fusion generally cannot be changed to a replacement later.[11]
Replacement. Complication and reoperation rates are significantly higher than after fusion.[3] Implants can loosen or wear, and survival figures become less predictable beyond ten years.[4] It is not right for everyone.[11]
Both. Time with the leg immobilised carries a risk of blood clots, which is why clot prevention is used.[9] No result is guaranteed.
Both operations relieve pain; each carries its own trade-offs.
Both operations relieve pain; each carries its own trade-offs.
Both operations relieve pain; each carries its own trade-offs.
Fusion. Once the bones unite, fusion reliably relieves pain. UK patient information from one NHS trust says about 9 in 10 people can expect a significant improvement in pain, mobility and quality of life.[12] That is one service’s figure, not a promise.
Replacement. Pooled data on implants from 2013 onwards, with at least five years of follow-up, put overall survival at about 93%.[4] Older designs did less well: about 78% at five years and 77% at ten in a 2007 review, and 85.9% and 71.1% in a review of one older implant.[2][5] Predictions become less reliable beyond ten years.[4]
Together. Overall outcomes, pain and satisfaction are similar between the two.[3] Every figure is an average with a date on it, not a personal promise.
OrthoKinetics Recovery Reflection
Recovery reflection
If your ankle has been negotiating with you for years, what is it asking of you this month?
An arthritic ankle is rarely a sudden event. It is more often a long conversation, carried on through every step and stair. What have you been asking of it? What might it be asking of you?
What would it mean to measure this ankle against the life you still want to walk through?
A worn joint cannot be young again. A life that keeps working is a different measure.
An arthritic ankle is not finished. It is negotiating.

Questions people often ask
Common ankle arthritis questions
Common ankle arthritis questions
Can an old ankle sprain or fracture lead to arthritis years later?
Sometimes. Repeated sprains and long-term instability can damage the cartilage over years, and a broken ankle can lead to arthritis years later. Published figures put 56 to 80% of ankle arthritis after a previous injury. It is possible, not inevitable.[4][13][14]
What does ankle arthritis feel like?
It often brings aching pain in and around the ankle, worse with walking, stairs or longer activity. Stiffness after rest is common, and swelling can come with activity and ease with rest.
What can I do for ankle arthritis without surgery?
Most people respond to simpler measures, at least initially. These include changing activity, supportive footwear or an ankle-foot orthosis, walking aids and medicines. A corticosteroid injection may ease pain in selected cases.[1][9][10]
Do injections help ankle arthritis?
A corticosteroid injection can ease pain for a period, and it is sometimes used to help show where pain comes from. It does not cure arthritis or restore cartilage. Other injections, such as hyaluronic acid, did not gain consensus support.[1][11]
What is the difference between ankle fusion and ankle replacement?
Fusion removes the worn joint so the bones unite. It relieves pain but leaves the ankle stiff. Replacement resurfaces the joint so it keeps moving. Overall outcomes are similar, with replacement offering more motion and fusion showing fewer complications.[3][9]
Can I walk normally after an ankle fusion?
The ankle itself no longer bends, but the foot’s other joints keep about half of its up-and-down motion. Walking mechanics change, and a rocker sole may help. How well you walk afterwards varies from person to person.[9][10][11]
How long does an ankle replacement last?
No one can say for an individual. In pooled data on modern implants, overall survival was about 93% at five years or more. Older designs had lower figures, and predictions become less reliable beyond ten years.[2][4][5]
Who is suitable for an ankle replacement?
Replacement generally suits older, lower-demand patients without major deformity or instability. It is usually not advised with severe deformity, marked instability, previous ankle infection or collapse of the talus. “Usually under 45” is only an indicative guide.[11]
Is keyhole surgery an option for ankle arthritis?
Sometimes, in a limited way. It may help earlier-stage problems, such as loose fragments or bone spurs. The specialist panel did not agree that it treats ankle arthritis itself.[1][9]
Is ankle replacement an established operation?
Yes. In the UK, NICE lists total ankle replacement as an established procedure, so it is a mainstream operation, not an experimental one.[8]
Costs and insurance
Costs and insurance
Practicalities
Cost, MediSave and insurance
A cost estimate for surgery can be given only after a consultation and assessment, once a surgical plan has been developed. Each individual condition is unique — implants used, time taken, and other factors contribute to the overall estimate. The estimate will be provided to you by the clinic should you decide on surgical management, and will also be used to assist in obtaining pre-authorisation from insurance where applicable.
A surgical estimate separates surgeon, anaesthetist, hospital or facility, implant and consumable costs, and the MOH publishes national fee benchmarks for common procedures. For how costs, MediSave and insurance work in Singapore, see Costs, insurance and MediSave, explained.
Insurance panels. Dr Sean Leo, Orthopaedic Surgeon, is on the specialist panels of Great Eastern (GE Panel), HSBC Life (HSBC Life Shield) and Singlife (Singlife Shield), and on the Prudential Panel. AXA Insurance Singapore became part of HSBC Life in 2023, and former AXA Shield plans are now HSBC Life Shield plans.
Corporate health plans. Dr Leo is on the panels of both Alliance Medinet and iXchange, which administer medical benefits for many company health plans. If your company plan uses either panel, you can see Dr Leo as a panel doctor.
If your company uses a different panel. Some company plans still let you see a doctor of your choice outside their panel, then claim reimbursement. This varies from plan to plan, as may the co-payment, so please check your benefits with your company’s HR department.
Panel arrangements change from time to time, so please confirm with your insurer or your company’s plan administrator before your appointment.
Dr Leo is on the panels shown. If your insurer is not listed, you may ask whether co-management with an Orthosports surgeon partner on that panel is clinically and administratively appropriate. Orthosports surgeon partners are collectively on the panels of all Shield plans.
Specific benefits, pre-authorisation, reimbursement and cashless treatment depend on the individual policy and insurer approval and are not guaranteed.
Ask the clinic team for current information about fees, panel status, pre-authorisation and expected payment arrangements. Insurance coverage and out-of-pocket costs depend on the individual policy and the insurer’s decision; no coverage is guaranteed.

Final next step
Reading about a problem is a starting point. An assessment brings together the history, an examination where needed and any useful tests, and helps you and your clinician decide what to do next. How much physical examination is needed is a matter of clinical judgement. It may be limited when pain makes an examination unreliable, or when imaging clearly shows a problem that matches the symptoms, such as a fracture seen on an X-ray or an MRI scan that clearly shows an injury consistent with the symptoms. The Singapore Medical Council and the UK General Medical Council both allow remote medical consultations, where a physical examination is not possible, with safeguards: the doctor must be clear about the limits of an opinion formed without an examination, and whether an in-person examination is needed, or referral to other services, is left to the clinical judgement of the attending doctor.
Signs that need urgent help
Some symptoms should not wait for a routine appointment. Each item below says where to go.
After an injury
- The ankle or foot sits at an odd angle, a bone is showing, there is a deep cut, you are in severe pain, or the toes look blue or white or feel numb. Go to an emergency department or call 995.
- You felt a sudden pop or sharp pain at the back of the heel or calf, and pushing off or rising onto your toes is difficult. Arrange an urgent same-day assessment.
- It is very painful or the pain is getting worse, the swelling or bruising is large or spreading, or it hurts to put weight on the ankle or foot. Arrange an urgent same-day assessment.
At any time
- A joint, such as the ankle, is suddenly very painful, hot, red and swollen, especially with a fever or feeling generally unwell. Go to an emergency department or call 995.
- One calf or thigh is newly painful and swollen. Arrange an urgent same-day assessment. If you also feel short of breath or have chest pain, call 995.
If you have diabetes
- You have a foot sore and a fever or feel very unwell, or the foot is cold, pale or blue. Or skin on the foot or toes has turned black, or a sore looks deep, or there is pus or redness spreading up the foot. Go to an emergency department or call 995.
- You have a new foot sore, or a foot that is hot, swollen, changed in colour or leaking fluid, without the signs above. Arrange an urgent assessment within 24 hours.
If you are admitted by the doctor at the urgent care centre of one of these private hospitals, the Parkway Pantai hospitals (Mount Elizabeth Orchard, Mount Elizabeth Novena, Gleneagles and Parkway East), Farrer Park Hospital and Thomson Medical Centre, you may ask for Dr Sean Leo to be your attending orthopaedic surgeon. If you are instead discharged and referred for orthopaedic follow-up, you may contact the clinic to arrange an appointment. Both are subject to the hospital’s admission processes and to Dr Leo’s availability.
