Quick Answer
Total ankle replacement (TAR) is a joint-preserving surgical option for end-stage ankle arthritis that maintains ankle motion while eliminating pain. Unlike ankle fusion which locks the joint, TAR implants an artificial joint that mimics natural ankle movement. Dr. Tom Biernacki at Balance Foot & Ankle evaluates ankle arthritis patients for replacement candidacy and provides comprehensive surgical care.
What Is Total Ankle Replacement?
Total ankle replacement involves removing the damaged articular surfaces of the tibia and talus and replacing them with metal and polyethylene components that recreate the ankle joint’s natural gliding motion. Modern fourth-generation TAR designs use anatomically shaped components, porous metal coatings for biological fixation, and mobile-bearing polyethylene inserts that distribute forces more evenly.
TAR is indicated for patients with end-stage ankle arthritis—Grade 3 or 4 on the Kellgren-Lawrence scale—who have failed conservative management including bracing, orthotics, injections, and activity modification. The primary advantage over ankle fusion is preservation of sagittal plane motion that allows a more natural gait pattern.
The procedure has evolved dramatically over the past decade. First-generation implants from the 1970s-80s had unacceptably high failure rates. Current designs achieve 90-95% implant survival at 5 years and 80-85% at 10 years, making TAR a viable long-term solution for properly selected patients.
Total Ankle Replacement vs Ankle Fusion
Ankle fusion (arthrodesis) eliminates all ankle joint motion by fusing the tibia to the talus, creating a stable but stiff joint. While fusion reliably eliminates pain, the loss of motion transfers stress to adjacent joints—the subtalar and talonavicular joints—accelerating arthritis in these joints at a rate of 2-3% per year.
Total ankle replacement preserves approximately 75-80% of normal ankle dorsiflexion and plantarflexion, enabling a more natural gait, easier stair climbing, and better function on uneven terrain compared to fusion. TAR patients consistently score higher on functional outcome measures and report greater satisfaction with daily activities.
However, fusion remains the preferred option in certain situations: patients under 50 with high physical demands, heavy laborers, patients with significant ankle deformity or bone loss, those with active infection, neuropathy causing sensory loss, or inadequate soft tissue coverage. Ankle fusion has a 95%+ union rate and provides reliable lifetime pain relief.
Who Is a Good Candidate for Ankle Replacement?
The ideal TAR candidate is over 50 years old with end-stage ankle arthritis, moderate activity level, good bone quality, stable ankle ligaments, correctable alignment, and adequate soft tissue coverage. Post-traumatic arthritis from previous ankle fractures is the most common indication, followed by primary osteoarthritis and inflammatory arthritis.
Body mass index below 30 is preferred because excess weight increases the mechanical stress on the implant and accelerates polyethylene wear. However, BMI alone should not exclude a patient—overall health, bone quality, and activity level are equally important considerations.
Contraindications to TAR include active ankle infection, severe osteoporosis, Charcot neuropathy, significant talar avascular necrosis, severe coronal plane deformity exceeding 15 degrees that cannot be corrected at the time of surgery, and peripheral vascular disease with inadequate healing potential.
The Surgical Procedure and Modern Implant Designs
TAR surgery is performed through an anterior ankle incision with the patient under general or regional anesthesia. The damaged tibial and talar surfaces are cut using precision alignment guides, and the implant components are press-fit into the prepared bone surfaces. Patient-specific instrumentation using pre-operative CT scans improves component positioning accuracy.
Modern implant designs fall into two categories: fixed-bearing and mobile-bearing. Fixed-bearing implants (like the STAR and Infinity) have the polyethylene liner locked to the tibial component, while mobile-bearing designs (like the Salto Talaris) allow the liner to move between components. Both designs show comparable mid-term results.
Concurrent procedures are commonly performed alongside TAR. Up to 60% of TAR surgeries include additional procedures such as Achilles tendon lengthening, lateral ligament reconstruction, subtalar fusion, or osteotomy to correct alignment and optimize implant function and longevity.
Recovery and Rehabilitation After Ankle Replacement
The first 2 weeks involve strict elevation, wound care, and non-weight-bearing in a splint. Incision healing is critically important because the anterior ankle has limited soft tissue coverage, making wound complications a significant concern. Patients should plan for complete non-weight-bearing during this initial phase.
Weeks 2-6 transition to a walking boot with gradual progressive weight-bearing. Physical therapy begins with gentle ankle range of motion exercises to prevent stiffness while protecting the healing bone-implant interface. The goal is to establish functional range of motion early while respecting the biological healing timeline.
Full recovery takes 4-6 months, with continued improvement in strength and function for up to 12 months. Most patients achieve 10-15 degrees of dorsiflexion and 20-25 degrees of plantarflexion. Return to low-impact activities like walking, cycling, swimming, and golf is expected. High-impact sports are generally discouraged to protect implant longevity.
Long-Term Outcomes and Implant Longevity
Current total ankle replacement implants demonstrate 90-95% survival at 5 years and 80-85% at 10 years in published registries. Patient satisfaction rates consistently exceed 85%, with most patients reporting significant pain relief and improved function compared to their pre-surgical state.
The primary mode of implant failure is polyethylene wear and periprosthetic osteolysis, where bone surrounding the implant gradually weakens. Annual follow-up X-rays monitor for early signs of loosening or wear, allowing proactive intervention before catastrophic failure occurs.
If a TAR ultimately fails, revision options include implant revision with new components if bone stock is adequate, or conversion to ankle fusion as a salvage procedure. Conversion to fusion after TAR is technically more challenging than primary fusion due to bone loss, but achieves reliable pain relief in most cases.
⚠️ Red Flags: When to See a Podiatrist Immediately
- Ankle pain at rest and during sleep that is not relieved by any conservative treatment
- Ankle stiffness and grinding that prevents normal walking mechanics
- Progressive visible deformity of the ankle with increasing instability
- Inability to perform daily activities due to ankle arthritis pain
The Most Common Mistake
The most common mistake patients make is assuming that ankle fusion is the only surgical option for ankle arthritis. While fusion was the historical gold standard, modern total ankle replacement provides a viable motion-preserving alternative for properly selected patients. Equally problematic is seeking TAR when fusion would be the more appropriate and durable option. The key is thorough evaluation to match the right procedure to the right patient.

Frequently Asked Questions
How long does a total ankle replacement last?
Current implant designs show 90-95% survival at 5 years and 80-85% at 10 years. Younger, more active patients may wear out implants faster. If a replacement eventually fails, it can be revised or converted to an ankle fusion.
Can I run after total ankle replacement?
High-impact activities like running are generally discouraged after TAR to protect implant longevity. Walking, cycling, swimming, golf, and hiking on moderate terrain are encouraged.
Is total ankle replacement covered by insurance?
Yes, TAR is covered by most insurance plans and Medicare when medically necessary for end-stage ankle arthritis. Pre-authorization may be required. Out-of-pocket costs depend on your plan’s deductible and co-insurance.
How do I know if I need replacement or fusion?
The choice depends on your age, activity level, bone quality, deformity severity, and goals. Dr. Biernacki evaluates all factors and recommends the procedure most likely to provide the best long-term outcome for your specific situation.
The Bottom Line
Total ankle replacement is a proven, motion-preserving option for end-stage ankle arthritis in properly selected patients. Modern implants provide reliable pain relief and functional improvement while avoiding the adjacent joint degeneration associated with ankle fusion.
