What Is Ankle Osteoarthritis?
Ankle osteoarthritis is degenerative wear of the ankle joint, causing pain, stiffness, and joint swelling. ¹ NICE Guideline NG226, Osteoarthritis in over 16s: diagnosis and management, provides the framework for diagnosing and managing osteoarthritis across the UK, and applies directly to ankle osteoarthritis as part of its broader scope. ²
A Genuinely Important Difference From Hip and Knee Osteoarthritis
This is the single most important thing to understand about ankle osteoarthritis, and it's quite different from what you might expect based on the hip and knee. Most research on osteoarthritis has focused on the hip and knee, where post-traumatic osteoarthritis (caused by a previous injury) accounts for around 8% and 12% of cases respectively. ³ Ankle osteoarthritis tells a dramatically different story, up to 70% of ankle osteoarthritis cases may be associated with a previous ankle injury, with trauma being the most influential risk factor overall, causing roughly 70 to 80% of cases. ³ ⁴
This makes genuine biological sense too. The ankle joint actually has high articular congruence (the joint surfaces fit together very precisely) with thin cartilage and a better repair capacity than the hip or knee, but trauma alters the joint surface and changes how load is transmitted through the joint, setting the stage for degeneration even in a joint that is otherwise relatively well-protected. ⁴ Genuinely strikingly, patients with post-traumatic ankle osteoarthritis tend to present with advanced disease around 14 years earlier than those with non-traumatic ankle osteoarthritis. ⁴
Common Signs and Symptoms
Pain, particularly with weight-bearing and activity
Stiffness, often worse after rest
Joint swelling
Reduced range of movement
A history of previous ankle injury, particularly a significant sprain or fracture, in the majority of cases
Risk Factors
Previous ankle trauma, by far the dominant risk factor for ankle osteoarthritis specifically, particularly malleolar (ankle) fractures and significant ankle ligament injuries ³ ⁴
Ankle sprains, recognised as a leading cause of post-traumatic ankle osteoarthritis, despite being one of the most common musculoskeletal injuries overall ⁵
Joint malalignment and articular incongruity following injury, contributing factors in the development of post-traumatic disease ⁶
Inflammatory processes triggered by joint injury, inflammation following intra-articular ankle fractures has emerged as a genuine contributor that may speed up the progression toward osteoarthritis ⁶
Inflammatory conditions, such as rheumatoid arthritis ⁴
Joint instability and overload, recognised contributing factors alongside trauma ⁴
Having three or more risk factors together, research following patients for 18 years after ankle fracture found that having three or more risk factors gave a 60 to 70% probability of developing post-traumatic osteoarthritis, highlighting how these factors compound ⁷
What to Look Out For
Please seek prompt medical assessment if you experience:
Sudden, significant swelling, redness, or warmth around the ankle (possible infection)
Inability to bear weight following an injury
A visible deformity
Fever alongside ankle pain
Rapidly worsening symptoms not following the usual gradual pattern
How Is It Diagnosed?
Symptoms are often non-specific, pain, stiffness, and joint swelling, similar to osteoarthritis affecting other joints. ¹ Clinical assessment, alongside X-ray where appropriate, helps confirm the diagnosis and the severity of joint changes, particularly given how important previous trauma history is to understanding the likely cause in this specific joint.
Myths vs Facts
"My ankle arthritis is just from getting older." Possibly, but genuinely less likely than you might think compared to hip or knee arthritis. Given that up to 70% of ankle osteoarthritis cases are linked to a previous injury, it's well worth us understanding your history of ankle sprains or fractures, even ones from many years ago, as part of getting the full picture.
"That ankle sprain I had years ago has nothing to do with this." It may well have everything to do with it. Ankle sprains are a recognised leading cause of post-traumatic ankle osteoarthritis, and the joint changes following an injury can take many years to fully develop into symptomatic arthritis.
How We Can Help
NICE guidance for osteoarthritis emphasises education, exercise, and non-drug approaches as the foundation of management, with manual therapy considered as a genuine adjunct to exercise specifically for hip and knee osteoarthritis. ² Whilst NICE's specific manual therapy recommendation focuses on hip and knee, the same core principles of exercise-led management with supportive manual therapy apply sensibly to the ankle.
Osteopathic manual techniques and manual therapy: addressing restriction and compensatory tension around the ankle, foot, and lower limb, supporting an active exercise programme.
Deep tissue and sports massage: targeted soft tissue work for the muscles surrounding the ankle, supporting overall function and comfort.
Medical acupuncture and cupping: used alongside exercise-based treatment to support pain management.
Education and self-management support: research evaluating combined education and exercise programmes specifically for ankle osteoarthritis has been developed in direct reference to NICE's broader osteoarthritis guideline, reflecting growing recognition that this approach, well-established for the hip and knee, has genuine relevance for the ankle too. ⁸
Exercise: A Genuinely Important Part of Treatment
Exercise has a well-established evidence base across osteoarthritis of the hip and knee, and research is increasingly extending this same approach to the ankle specifically. ⁸
Range of motion and mobility exercise: supporting joint mobility and reducing stiffness.
Strengthening exercise: targeting the muscles surrounding the ankle to better support the joint, particularly relevant given how often post-traumatic instability contributes to ankle osteoarthritis.
Quadriceps and lower limb muscle function: research into post-traumatic osteoarthritis more broadly has highlighted how persistent muscle dysfunction following a joint injury can be a genuine contributing risk factor for long-term joint problems, reinforcing why addressing strength after any significant ankle injury matters, not just managing the original injury itself. ⁹
Balance and proprioceptive training: particularly relevant given the strong link between previous ankle ligament injury and instability in the development of ankle osteoarthritis.
Your practitioner will guide a structured, individualised exercise programme appropriate to your specific history and presentation.
What to Expect at Your First Appointment
We will take a thorough history, paying particular attention to any previous ankle injuries, even ones from many years ago, given how strongly these are linked to ankle osteoarthritis specifically. We will carry out a hands-on assessment of your ankle's range of movement, strength, and stability. We will explain clearly what we find and build an evidence-based treatment plan centred on exercise, with manual therapy used as a genuine adjunct.
Frequently Asked Questions
Do I need a scan? Clinical assessment is often the starting point, with X-ray imaging used where appropriate to confirm the diagnosis and assess the extent of joint changes.
Why are you asking about an ankle sprain I had years ago? Because it's genuinely relevant. Previous ankle injury is by far the dominant risk factor for ankle osteoarthritis, far more so than in the hip or knee, and understanding your injury history helps us build the most appropriate treatment plan.
Will I need surgery? Not necessarily, particularly in earlier stages. Conservative, exercise-based management remains an important first-line approach, in line with broader osteoarthritis treatment principles.
Could my old ankle sprain still be causing problems even though it felt fully healed? Yes, genuinely. The joint changes that lead to post-traumatic osteoarthritis can take many years to fully develop, which is exactly why thorough rehabilitation after any significant ankle injury matters so much.
