Ankle replacement surgery, or total ankle arthroplasty, is a procedure to address ankle joint issues, and it involves several steps. When other methods are ineffective, this surgery replaces damaged ankle components with artificial components. Here are the typical steps of the surgery:
Anesthesia Application
Before your surgery begins, a specialist will typically administer anesthesia. This is done to manage pain and keep you comfortable during the operation. Different types of anesthesia may be used. General anesthesia puts you into a deep sleep, so you are unaware of the surgery as it happens. Another option is a regional nerve block, which numbs your leg from the knee down. You might be awake but sedated with a nerve block.
The anesthesiologist can discuss the ideal option for you based on your health and the specifics of the surgery. They may ask questions about your medical history and any medications you take. After they administer anesthesia, they typically move you to the operating room once you are ready for ankle replacement. The surgical team prepares the area for the operation.
Incision Operation
A surgeon begins by making an incision on the front or side of your ankle. The location of the incision depends on the surgeon’s preferred approach and your specific anatomy. The surgeon then carefully moves muscles, nerves, and blood vessels aside to access the ankle joint. This provides a clear view of the bones that make up the joint. Retractors help to hold the tissues back, keeping the surgical field open. The team works precisely to expose the area needing repair.
Bone and Cartilage Removal
With the ankle joint exposed, the surgeon removes the damaged bone and cartilage. They use specialized instruments to make precise cuts to the ends of the tibia and talus, the two primary bones forming the ankle joint. A smooth, prepared surface becomes necessary for the new components.
The surgeon carefully measures the amount of bone to remove, ensuring the artificial joint fits correctly. They remove only the damaged sections, preserving as much healthy bone as possible. This part of the process demands precision and attention to detail. The team works together to prepare the bones for the next step.
They may place guides on the bones to direct the surgical saw, helping create the exact shapes needed for the implant components. The surgeon may insert small trial components to check the fit before placing the final implants, verifying alignment and motion. Any necessary adjustments take place at this stage.
Component Insertion
After preparing the bone surfaces, the surgeon inserts the artificial joint components. These components are typically made of metal and plastic. They are designed to mimic the natural movement of the ankle. A plastic liner may be placed between them, and the components are secured in place. This can be done in a few ways:
- Using a special bone cement.
- A “press-fit” method where the bone grows into the component over time.
Once the new components are in place, the surgeon checks the ankle’s movement and stability. At the end, the surgeon closes the incision with sutures or staples. They may apply a sterile dressing and place your ankle in a splint or cast to protect it.
Schedule Ankle Replacement Surgery
An ankle replacement involves several distinct phases, from anesthesia to the final closure. Following your surgeon’s post-operative instructions is a key part of the recovery process. If you are exploring options for ankle pain, the next step is to speak with a specialist. Contact a foot and ankle doctor today to schedule a consultation and discuss your health.
