Ankle arthritis is wear of the cartilage in the main ankle joint, where the shinbone (tibia) meets the talus. Unlike hip and knee arthritis, most ankle arthritis follows an injury: in one large series, 70% of arthritic ankles were post-traumatic, often years after a fracture or repeated sprains.1,2 It often affects younger, active people,3 and end-stage ankle arthritis can be as disabling as end-stage hip arthritis.5
- Deep ankle pain, stiffness and swelling, often years after a fracture or sprains1,3
- Diagnosed with weight-bearing X-rays4
- Bracing, shoe changes, activity changes and exercise come first2,7
- PRP was no better than placebo in a randomized trial of ankle arthritis10,11
- For end-stage arthritis, fusion and ankle replacement gave similar results in a large randomized trial18
Causes
- Previous injury: ankle fractures, cartilage injuries and long-standing ankle instability are the most common causes.1,3
- Inflammatory arthritis such as rheumatoid arthritis.1
- Primary (wear-and-tear) osteoarthritis, which is less common in the ankle than in the hip or knee.1,2
- Malalignment: a heel or ankle that tilts in or out loads one side of the joint.3
Symptoms
- Aching pain deep in the front of the ankle, worse with walking, stairs and uneven ground
- Stiffness, especially in the morning or after sitting
- Swelling after activity
- Pain and blocking when bending the foot upward, from bone spurs at the front of the ankle
- A limp or difficulty with longer walks
Diagnosis
Dr. Dold examines the ankle and the alignment of the whole leg and foot, and orders standing (weight-bearing) X-rays, which are the basis of diagnosis.4 A CT scan helps plan surgery, and an MRI can look at cartilage, bone bruising and tendons when X-rays don’t explain the pain. A numbing injection can help confirm that the ankle joint, rather than a nearby joint, is the main source of pain.
Non-surgical treatment
Most people start with non-surgical care, which centers on reducing pain and keeping you active:2,6,7
- Shoes and bracing: rocker-bottom soles, cushioned heels, an ankle brace or a custom ankle-foot orthosis
- Activity changes: swapping impact exercise for cycling, swimming or the elliptical
- Physical therapy for strength, balance and motion
- Weight management to reduce load on the joint
- Anti-inflammatory medicines when safe for you
Injections: what the research shows
- Cortisone: often used for short-term relief of flare-ups.
- Hyaluronic acid (gel): early studies showed pain relief with weekly injections, but the evidence is limited and much of it is borrowed from knee research.8,9
- PRP (platelet-rich plasma): in a well-designed randomized trial of 100 patients, PRP was no better than a placebo injection at 26 weeks or at 1 year.10,11 A pooled analysis that combined several joints reported some pain benefit in the ankle,12 but the higher-quality ankle-specific trial did not support it.
Responses vary, and PRP may still help selected patients, particularly those hoping to delay surgery. Dr. Dold discusses the evidence openly so you can decide whether an injection is worth trying.
Joint-preserving surgery
For earlier arthritis, or arthritis on one side of the joint, the goal is to delay or avoid fusion or replacement:
- Ankle arthroscopy: removing bone spurs and inflamed tissue through small incisions. Results were good or excellent in 77% of ankles with early arthritis and 53% with moderate arthritis.13
- Realignment osteotomy (supramalleolar osteotomy): cutting and realigning the shinbone to shift load to the healthier side of the joint. Across 851 patients, function improved with low complication rates, and about 10% later needed fusion or replacement.14
- Distraction arthroplasty: an external frame that gently separates the joint for several weeks. Some reviews report promising short- to mid-term results,15,17 while others found small improvements and high failure rates,16 so careful patient selection matters.
End-stage arthritis: fusion or replacement?
When the joint is worn out and non-surgical care no longer helps, the two main operations are ankle fusion (arthrodesis) and total ankle replacement (arthroplasty).6,7
In the TARVA randomized trial of 303 patients, both operations improved pain and function similarly at 1 year. Replacement had more wound-healing problems and nerve injuries, while fusion had more blood clots and a 7% rate of symptomatic nonunion.18 Large Canadian studies found similar results: function was comparable, but replacement had more reoperations and complications,19,21 and at long-term follow-up 70% of fusions vs 58% of replacements needed no further surgery.20
Fusion is often favored for younger, heavy-labor patients, and replacement for older, less active patients,22 but each decision depends on your age, activity, alignment, bone quality and the joints around the ankle. If total ankle replacement is the right option for you, Dr. Dold can refer you to a foot and ankle colleague who performs it.
Ankle fusion
Ankle fusion joins the tibia and talus so the painful joint no longer moves. It reliably relieves pain. When the ankle is not badly deformed, it can often be done arthroscopically. Compared with open fusion, arthroscopic fusion has been associated with higher fusion rates, less blood loss and shorter hospital stays,23,24 and better scores at 1 and 2 years.25
After fusion, the joints next to the ankle take on more motion. Whether fusion causes arthritis in those joints is debated,26 but arthritis in surrounding joints appears to increase over time.27 Most people walk well after a fusion, though gait is not completely normal.28
Total ankle replacement
Ankle replacement resurfaces the joint with metal and plastic components so the ankle keeps some motion. It improves pain, function and motion, with benefits shown out to 10 years.29 Replacement gives more ankle motion and a more symmetrical gait than fusion, although neither restores completely normal walking.28
Implants can wear or loosen over time:
- National joint registries report revision-free survival of 80% to 91% at 5 years and 66% to 84% at 10 years.33
- Earlier reviews reported implant survival of 80% to 95% at 8 to 12 years,30 and studies with at least 10 years of follow-up report survivorship from 66% to 94.4%.31
- Revision and reoperation become more common with longer follow-up.32,34
- Obesity was not linked to more early complications,35 but was linked to higher odds of revision.36
If a replacement fails, it can be revised or converted to a fusion, though results of these salvage operations are less predictable.37
Recovery
- Arthroscopy: usually outpatient, with walking in a boot as comfort allows and a return to normal shoes over a few weeks.
- Fusion and replacement: a period of protected weight-bearing in a splint or boot, followed by physical therapy. Full recovery after fusion or replacement takes many months.
Dr. Dold reviews your expected recovery timeline before surgery based on the procedure and your health.
Frequently asked questions
Is ankle arthritis the same as hip or knee arthritis?
Ankle cartilage is thinner and the arthritis is usually caused by a previous injury rather than age alone. Most ankle arthritis is post-traumatic, and it often affects younger people.
Do PRP injections help ankle arthritis?
In a randomized trial of 100 patients, PRP was no better than a placebo injection at 26 weeks or 1 year. Dr. Dold reviews this evidence with you before recommending any injection.
Which is better, ankle fusion or ankle replacement?
Neither is right for everyone. In a randomized trial both improved pain and function similarly at 1 year. Replacement keeps motion but has more reoperations over time; fusion is very durable but stiffens the ankle. Age, activity, alignment and bone quality guide the choice.
How long does an ankle replacement last?
Registry data show that most implants are still in place at 5 years, and many last 10 years or more, but some need revision over time.
Can I walk normally after an ankle fusion?
Most people walk well after a fusion, especially with supportive or rocker-soled shoes. Neither fusion nor replacement fully restores a normal gait.
