How Long Will My Ankle Replacement Last?

UK National Joint Registry data shows that around 90% of ankle replacements are still working at 5 years and roughly 86% at 10 years — and many continue to function for considerably longer. How long your own ankle replacement lasts depends on the implant, your age and activity level, and the experience of your surgeon.

A total ankle replacement (also called total ankle arthroplasty, or TAR) is an operation for severe ankle arthritis. A foot and ankle surgeon removes the worn, painful surfaces of the ankle joint and replaces them with metal and plastic components that allow the joint to keep moving. For appropriate patients with end-stage ankle arthritis, it is an alternative to ankle fusion.

The main appeal of an ankle replacement is that it preserves movement, which can make walking feel more natural and may protect the neighbouring joints in the foot. The trade-off is that, like any joint replacement, it will not last forever — so understanding its likely lifespan is an important part of deciding whether it is right for you.

The most reliable figures for UK patients come from the National Joint Registry (NJR), which tracks ankle replacements across England, Wales and Northern Ireland. The most recent large analysis reported the following survival rates, where “survival” means the implant is still in place and has not needed to be removed or exchanged:

Figures vary between countries and between implant designs, with some international registries reporting 10-year survival anywhere from roughly 70% to 90%. Newer-generation implants and surgery performed in specialist, higher-volume centres tend to sit at the better end of that range. As a rule of thumb, a contemporary ankle replacement performed by an experienced foot and ankle surgeon should be expected to last at least 10 years, and frequently longer.

Several factors influence the lifespan of an ankle replacement:

• Your age and activity level. Younger, more active patients place greater demand on the implant, which can shorten its working life. Higher-impact activities such as running and jumping accelerate wear.
• Body weight. Higher loads across the joint increase wear over time.
• The implant design. Modern third- and fourth-generation implants have improved survival compared with older designs.
• Surgeon experience and case volume. Ankle replacement is technically demanding. Outcomes are consistently better when surgery is carried out by a specialist foot and ankle surgeon who performs the procedure regularly.
• Bone quality and alignment. Good bone stock and a well-aligned foot and ankle help the implant settle and last.
• The original cause of the arthritis. Post-traumatic, osteoarthritic and inflammatory arthritis can behave differently.

If an ankle replacement loosens or wears out, it does not mean you are out of options. In many cases the worn plastic component alone can be exchanged. In others, the implant can be revised — replaced with new components — or converted to an ankle fusion. Because a small proportion of replacements will eventually need attention, surgeons plan for this from the outset, which is one reason your age at the time of surgery is part of the conversation.

This is one of the most important decisions in foot and ankle surgery, and there is no single right answer. An ankle replacement keeps the joint moving but has a finite lifespan; an ankle fusion is extremely durable but permanently stiffens the joint. The best choice depends on your age, activity level, the condition of your neighbouring joints, and your personal priorities. A detailed assessment with a specialist foot and ankle surgeon is the only way to weigh these factors properly for your situation.
