Ankle Replacement

Ankle replacement replaces damaged ankle joint surfaces with an implant to reduce pain and preserve useful movement.

Ankle replacement, also called total ankle arthroplasty, removes worn joint surfaces and fits shaped implant components inside the ankle. A spacer allows the components to move against each other. Unlike fusion, the operation aims to retain some up-and-down ankle motion. The surgeon chooses the design and fixation method after examining your bones, alignment, activity needs, and imaging.

Ankle pain from the damaged joint may improve after the operation, but early swelling, wound soreness, and stiffness can hide the benefit. You will usually protect the ankle at first, then increase weight-bearing and walking as healing allows. Movement and comfort often build gradually through physiotherapy rather than arriving all at once.

Expected short-term effects include swelling, bruising, stiffness, altered walking, and soreness around the incision. Possible surgical problems include wound trouble, infection, blood clots, nerve irritation, implant loosening, or wear. Contact the surgical team promptly for worsening redness, drainage, fever, calf swelling, or sudden breathlessness.

An ankle replacement is intended as a long-term joint reconstruction, not a course of medication. The implant remains in place unless a later procedure is needed. Follow-up visits and exercise continue after the wound has healed because strength, balance, and safe loading affect how the ankle performs.

The operation treats the ankle joint itself, so pain from nearby tendons, nerves, or the foot may need separate assessment. Implant materials can include metal components and a plastic bearing; a titanium implant may be part of the fixation system. Your orthopaedic team will discuss the exact device and restrictions.

It may be considered for adults with advanced ankle arthritis whose pain and limited movement continue despite measures such as activity adjustment, supportive footwear, medication advice, injections, or physiotherapy. The decision depends on bone quality, ankle alignment, skin condition, activity expectations, and other health factors. A specialist compares replacement with other options for your particular joint.

The team reviews your medicines and prepares the operative leg. Under anaesthesia, the surgeon reaches the ankle through an incision, removes damaged bone and cartilage, prepares the surfaces, and positions the implant components. Alignment and movement are checked before the incision is closed. A dressing and temporary support protect the ankle while the first stage of healing begins.

At first, keep the ankle elevated as instructed and use crutches or another aid. The surgeon sets the pace for moving from protected loading to fuller walking. Later appointments check the wound, movement, alignment, and implant position. Physiotherapy can address calf strength, ankle range, gait, and confidence on uneven ground. Recovery varies with the operation and your starting mobility.

Every operation has risks, including bleeding, infection, anaesthetic reactions, delayed wound healing, nerve symptoms, stiffness, and blood clots. The implant can wear, loosen, shift, or require revision over time. Seek urgent help for chest pain or severe breathing difficulty; contact the team for a hot, increasingly painful wound or a newly swollen calf.

Depending on the joint and your goals, alternatives may include activity changes, a brace, footwear changes, pain treatment, injections, physiotherapy, or ankle fusion. Joint fusion surgery removes movement at the painful joint to create a solid connection, so your specialist will explain the trade-off between motion and stability.

Look for an orthopaedic surgeon who regularly evaluates ankle arthritis and discusses both replacement and fusion. Ask how your bone quality, alignment, skin health, activity goals, and rehabilitation access affect the recommendation. Before booking, clarify the planned implant, weight-bearing instructions, follow-up schedule, and who to contact if recovery changes.
