⚡ Quick Answer: Total Ankle Replacement (TAR) Surgery
Total ankle replacement (TAR) is an established surgical treatment for end-stage ankle arthritis that preserves ankle motion while eliminating bone-on-bone pain. It is an alternative to ankle fusion (arthrodesis) for appropriate candidates. Modern implant designs have substantially improved outcomes — 90%+ survivorship at 10 years in well-selected patients. Recovery takes 3–6 months for most functional activities, with full rehabilitation complete at 12 months.

End-stage ankle arthritis is a debilitating condition that affects hundreds of thousands of Americans. For decades, ankle fusion was the only reliable surgical option — but it comes at the cost of eliminating ankle joint motion, which transfers stress to adjacent joints and can cause long-term mid-foot arthritis. Total ankle replacement preserves motion and, in the right patient, produces superior functional outcomes with comparable pain relief.
As a foot and ankle surgeon at Balance Foot & Ankle in Howell and Bloomfield Hills, I evaluate ankle arthritis patients for both replacement and fusion, and help each patient understand which option is most appropriate for their anatomy, activity goals, and health profile.
TAR vs. Ankle Fusion — Choosing the Right Option
| Factor | Total Ankle Replacement | Ankle Fusion |
|---|---|---|
| Joint motion preserved | Yes — 20–30° of dorsiflexion/plantarflexion | No — joint permanently stiffened |
| Best candidate age | 55+ with lower activity demands | Any age; especially younger, active patients |
| Adjacent joint protection | Better — preserves normal load transfer | Adjacent joint OA accelerated over 10–15 years |
| Implant survivorship | ~90% at 10 years (modern implants) | Very durable — no implant to wear out |
| Recovery time | 3–6 months functional; 12 months full | 3–4 months NWB; 6–9 months full recovery |
| Revision options | Implant revision or conversion to fusion | Limited revision options if fusion fails |
Who Is a Good Candidate for TAR?
Ideal TAR candidates are adults over 55 with post-traumatic or osteoarthritic ankle arthritis who have adequate bone stock, a stable ankle alignment (neutral or correctable varus/valgus), intact ligaments, and realistic activity expectations. TAR is not suitable for patients with severe malalignment, avascular necrosis of the talus, active infection, significant peripheral vascular disease, or extremely high physical demands (heavy manual labor, high-impact sports).
The TAR Surgical Procedure
Total ankle replacement is performed through an anterior (front-of-ankle) approach under general or spinal anesthesia. The damaged tibial and talar joint surfaces are precisely resected using cutting jigs, and titanium components are implanted with a polyethylene bearing between them. Modern fixed-bearing and mobile-bearing systems both produce excellent results. Surgery takes approximately 1.5–2.5 hours; most patients go home the same day or after one overnight stay.
Watch: Ankle Sprains — When Chronic Instability Leads to Arthritis
Dr. Tom explains how repeated ankle sprains progress to chronic instability and, ultimately, post-traumatic arthritis that may require surgical intervention:
TAR Recovery Timeline
| Phase | Timeline | Activity |
|---|---|---|
| Immobilization | 0–4 weeks | NWB splint/cast; wound care |
| Progressive WB | 4–8 weeks | Walking boot; PT begins ROM exercises |
| Rehabilitation | 2–6 months | Shoe gear; strengthening; balance training |
| Full activity | 6–12 months | Low-impact sport; cycling; swimming |
Frequently Asked Questions
How long does a total ankle replacement last?
Modern third-generation TAR implants demonstrate approximately 85–92% survivorship at 10 years, with some long-term studies showing good outcomes at 15+ years. Survivorship depends on patient selection, alignment, activity level, and implant system. Failed implants can be revised to a new replacement or converted to ankle fusion in most cases.
Is TAR covered by insurance?
Yes — total ankle replacement is covered by Medicare and most commercial insurance plans when medically indicated for end-stage ankle arthritis that has failed conservative management. Prior authorization is typically required. Our billing team assists with the authorization process. Call (810) 206-1402 for specific insurance questions.
Can I walk normally after total ankle replacement?
Most patients walk with a near-normal gait pattern following successful TAR — a key advantage over ankle fusion, which produces a characteristic stiff-legged gait. Full gait restoration takes 6–12 months of progressive rehabilitation. Most patients report they walk “like a normal person” by month 6–9.
What are the risks of total ankle replacement?
The main risks are wound healing complications (wound breakdown, infection), nerve injury (peroneal nerve branches near the anterior approach), implant loosening, and component subsidence into the bone. The overall serious complication rate with experienced surgeons is approximately 5–10%. Revision to fusion is possible if the implant fails but requires intact bone stock.
TAR vs. fusion — which has better long-term outcomes?
Both procedures produce good long-term outcomes in appropriate candidates. TAR preserves motion and better protects adjacent joints, which matters most in patients who will live with the result for 20–30 years. Fusion is more durable in younger, heavier, or more active patients and has a lower short-term complication rate. The choice requires individualized discussion weighing your age, activity goals, bone quality, and alignment.
