Osteoarthritis of the ankle and foot joints
Osteoarthritis may affect the tibiotalar, subtalar or midfoot joints. The location of pain and the type of ground on which it occurs help identify the responsible joint, and the cause is often post-traumatic.
Clinical context
What you should know
Unlike hip and knee osteoarthritis, ankle osteoarthritis often develops after fractures or instability, including in younger, active adults.
Several joints may look abnormal on radiographs, but treatment must target the true source of pain. Diagnostic injections sometimes have a selective role.
First step
Consultation and assessment
Weight-bearing radiographs show joint space, alignment and deformity. CT clarifies bone and joint anatomy for planning, while MRI is reserved for specific questions about cartilage and soft tissues.
Assessment covers gait, stability, movement in adjacent joints, skin condition, circulation, smoking, diabetes and activity level.
Stepwise treatment
Options are chosen according to the diagnosis and treatment goal
Conservative treatment
- education and tailored exercises for movement, strength and walking tolerance
- stiff-soled or rocker-soled footwear, orthoses and walking aids
- weight management and pain relief after assessing individual risks
- no promises of benefit from intra-articular hyaluronic acid or PRP for ankle osteoarthritis, as current evidence does not show consistent benefit
Medication, injections and devices each have their own indications and contraindications. They are not recommended automatically and do not replace a diagnosis or monitoring of the response.
When surgery is considered
Fusion eliminates painful movement and can be applied to the joint responsible for the symptoms. For the tibiotalar joint, total ankle replacement preserves some movement in carefully selected patients. Alignment, bone quality, ligaments and adjacent joints guide the choice.
Do not delay
Signs that require prompt assessment
- sudden pain and inability to bear weight after injury
- a red, hot and very swollen joint accompanied by fever
- a cold or pale foot, or loss of sensation
In an emergency or if symptoms are severe, call 112 or go to the nearest emergency department.
Frequently asked questions
Concise answers, without blanket promises
Does fusion mean I will no longer be able to walk?
No. The aim is to eliminate painful movement in the affected joint and achieve stable weight-bearing. Walking also depends on the adjacent joints, alignment and rehabilitation.
Is total ankle replacement suitable for everyone?
No. Selection takes account of alignment, stability, bone quality, skin, circulation, neuropathy, activity and osteoarthritis in adjacent joints.
