The problem being treated
End-stage ankle arthritis causes pain and stiffness with every step.
Related conditions: Foot & Ankle Arthritis.
When surgery may be appropriate
- End-stage ankle arthritis that limits daily life despite bracing and injections
- Adequate bone quality and alignment
- Good circulation and no active infection
Replacement may not suit patients with severe deformity, poor bone quality, neuropathy, active infection, or very high-impact activity goals. Ankle fusion remains an excellent option for many of these patients.
How the procedure works
- Damaged joint surfaces are removed from the tibia and talus.
- Metal components are fixed to each bone, with a plastic bearing between them.
- Alignment problems are corrected at the same time when needed.
Typical restrictions after surgery
- Splint and non-weight-bearing initially
- Progressive weight-bearing in a boot
- Physical therapy
Your surgeon will give instructions specific to your procedure; these are general guidelines only.
General recovery phases
- Weeks 0–2Splint; wound healing.
- Weeks 2–6Boot; weight-bearing progressed as directed.
- Weeks 6–12Physical therapy for motion and strength.
- Months 3–12Return to low-impact activities such as walking, cycling, and golf.
Frequently asked questions
How long does an ankle replacement last?
Modern implants are designed to last many years, but lifespan varies with activity, alignment, and bone quality.
Replacement or fusion?
Replacement preserves motion; fusion is very durable. The decision depends on your anatomy, health, and goals.
Outcomes vary from patient to patient. This page is educational and does not replace a consultation; candidacy is determined after an examination and imaging.
