Total Ankle Replacement
Ankle arthritis can be treated with total ankle replacement, also known as total ankle arthroplasty, a surgical procedure commonly used by foot and ankle orthopaedic surgeons. Arthritis can result from normal aging or injuries such as a broken ankle or dislocation, which eventually lead to cartilage loss, pain, and deformity.
During a total ankle replacement procedure, the damaged ankle joint is removed and replaced with an artificial implant made of plastic and metal. The primary objective of this procedure is to provide pain relief while maintaining ankle motion, enabling patients to experience less pain and better function during physical activity.

What happens during surgery?
During ankle replacement surgery, the patient is typically placed under general anaesthesia or a nerve block. To minimize bleeding and facilitate visualization during the procedure, the surgeon applies a tourniquet. Depending on the type of implant being used, the surgeon will approach the ankle from the front or the side. They will then cut the bone and install the metal and plastic components that replicate the ankle joint. In some cases, additional procedures may be necessary to properly align the foot and ankle and correct any deformities. The surgeon will then use stitches or staples to close the incisions and apply a splint.
How to prepare?
Here are some tips to prepare for ankle replacement surgery:
- Follow your surgeon’s instructions: Your surgeon will give you specific instructions for how to prepare for your surgery.
- Quit smoking: Smoking can slow down the healing process and increase the risk of complications during and after surgery.
- Get in shape: Strengthening your muscles and improving your overall health can help you recover from surgery more quickly.
- Arrange for help at home: You will need assistance with daily tasks during the first few weeks after surgery. Plan to have someone available to help you during this time.
- Prepare your home: Make sure your home is safe and accessible for you after surgery.
- Stock up on supplies: Surgeon may recommend certain supplies such as ice packs, bandages, and a shower chair.
- Follow fasting instructions: Surgeon may instruct you to stop eating and drinking for a certain amount of time before surgery.
After Total Ankle Replacement surgery?
After a total ankle replacement surgery, the patient needs to be non-weightbearing for a variable period in a cast or boot to allow the implants to heal in place. The procedure is typically done in the hospital, and the patient may stay for several nights. Elevation is crucial for many days after the surgery to manage swelling and promote wound healing. Once the surgical wounds are healed, some foot and ankle orthopaedic surgeons may allow the patient to start gentle range-of-motion exercises, even if they are non-weightbearing. Weightbearing usually starts a few weeks after surgery, depending on the X-ray results showing good healing.
