What is ankle replacement done with?

During surgery, the damaged ends of the shin bone and ankle bone are shaped to receive an artificial joint. A metal component is placed at each prepared bone surface, with a mobile plastic bearing between them. The parts are selected and positioned to fit your anatomy and support smooth ankle motion. Some implants use titanium or another medical-grade metal, while the bearing is commonly a strong polyethylene material.

The implant does not replace every structure around the ankle. Ligaments, tendons, muscles, and the surrounding skin still help provide balance and control. Your surgeon may discuss whether the replacement is fixed with bone growth, bone cement, or a combination, depending on the implant design and bone quality.

Before surgery, tell the team about medicines, allergies, previous operations, skin problems, and any dental or other infection concerns. Afterward, follow the planned weight-bearing limits and wound-care instructions. Physiotherapy usually works on swelling control, ankle movement, strength, walking technique, and safe progression from support to independent walking. Do not change activity levels or use impact exercise until your surgical team says the joint is ready.

Seek prompt medical advice for increasing wound redness, drainage, fever, worsening pain, new numbness, or a foot that becomes unusually cold or pale. Sudden calf swelling or pain, chest pain, or shortness of breath needs urgent assessment. These symptoms can have causes unrelated to the implant, so do not wait for a routine appointment.

Ask which implant design and bearing are planned, how the components will be fixed, when you may put weight through the ankle, and which activities may place excess load on the replacement. Ask how follow-up visits will assess movement, alignment, and symptoms.
