When Is Ankle Arthroplasty Considered?

The operation may be considered for severe ankle arthritis that still limits activity after nonsurgical treatment. A foot and ankle surgeon evaluates bone quality, alignment, circulation, and nerve function. Some conditions make an implant less suitable. Ankle fusion may be discussed as another surgical option.

How Is the Ankle Joint Replaced?

The surgeon reaches the ankle through an incision at the front or side of the joint. Damaged cartilage and bone surfaces are removed. Metal and plastic components are fitted to recreate the moving joint surfaces. Additional work may be needed to correct ankle alignment.

What Happens During Recovery?

A splint, cast, or boot protects the ankle after surgery. Patients generally avoid putting weight on the operated foot during early healing. Weight bearing and physical therapy begin according to the surgeon's assessment of the wound and implant. Recovery can continue for several months.

What Are the Risks of Ankle Arthroplasty?

Risks include infection, blood clots, nerve injury, and wound healing problems. A bone near the implant can fracture during or after surgery. Implant parts may loosen or wear over time. Further surgery may be needed if the replacement fails.

Frequently Asked Questions About Ankle Arthroplasty

Is ankle arthroplasty the same as ankle replacement?

Yes. Ankle arthroplasty is the medical term for replacing damaged ankle joint surfaces with an implant.

Does ankle replacement preserve movement?

It is designed to retain ankle motion while relieving pain. The amount of movement afterward varies by patient.

How does ankle replacement differ from fusion?

Replacement uses an artificial moving joint. Fusion joins the ankle bones so that joint no longer moves.

Can I walk on the ankle right after surgery?

Patients commonly need a period without weight bearing. The surgeon determines when it is safe to begin putting weight on the foot.
