Total ankle joint replacement

Total ankle joint replacement, also known as ankle arthroplasty, is a surgical treatment for people with advanced ankle arthritis. Arthritis occurs when the cartilage that cushions the ankle joint wears away, causing pain, stiffness, swelling and reduced mobility. This can make everyday activities such as walking, standing and climbing stairs very difficult.

Ankle replacement surgery involves removing the damaged joint surfaces and replacing them with artificial components designed to move smoothly and mimic the function of a healthy ankle.

Your surgeon may recommend ankle replacement if:

• You have severe ankle pain that does not improve with non-surgical treatments
• Arthritis significantly affects your mobility and quality of life
• The ankle joint is stiff or painful despite physiotherapy, medication or injections

Unlike ankle fusion surgery, ankle replacement aims to preserve movement in the joint, which can help maintain a more natural walking pattern.

Who is a Candidate

Total ankle replacement is typically offered to patients who have:

• End-stage ankle arthritis (post-traumatic, osteoarthritis, or inflammatory arthritis)
• Persistent pain and disability despite conservative management (physiotherapy, bracing, injections)
• Good bone quality and alignment (minimal deformity or correctable deformity)
• Low to moderate activity demands

It is generally less suitable for:

• Younger, high-impact or very active patients
• Severe deformity, infection, poor soft tissue, or neuropathy (e.g. Charcot joint)
• Severe osteoporosis or vascular disease.

Recovery Timeline

(May vary with provider)

• 0–2 weeks: Immobilisation in a splint or cast; non-weight-bearing
• 2–6 weeks: Transition to boot; gradual partial weight-bearing
• 6–12 weeks: Progression to full weight-bearing; begin physiotherapy
• 3–6 months: Improved strength, mobility, and function
• 6–12 months: Maximal recovery and functional outcome.

Full recovery varies depending on patient health and rehabilitation compliance.

Benefits

• Significant pain relief
• Preservation of ankle motion (unlike ankle fusion)
• Improved gait and function
• Reduced stress on adjacent joints, lowering the risk of secondary arthritis.

Risks

• Infection or wound healing problems
• Implant loosening or failure over time
• Nerve or blood vessel injury
• Blood clots
• Reduced implant lifespan (possible need for revision surgery)

This is just an outline. Your specialist orthopaedic surgeon will be able to talk to you about these issues in more detail and make sure that there is informed consent.

Total ankle replacement is an effective option for selected patients with end-stage ankle arthritis, offering pain relief and motion preservation. However, careful patient selection is essential due to implant longevity and complication risks.
