Ankle Replacement Surgery Procedure
Before the procedure, one may need additional imaging tests, like X-rays, CT scan, or MRI. Patient should tell their doctor about all the medicines they take, including over-the-counter medicines like aspirin. Also, tell any recent changes in their overall health, such as a fever.
Ankle replacement surgery requires general anesthesia with a regional nerve block and 1-2 days in the hospital. It is performed through an incision approximately 15 cm (6 inches) long over the front of the ankle.
The worn out joint surfaces are cut away and replaced with a pair of pieces of metal with a piece of hard plastic between them that permits the joint to maneuver freely.
If the calf muscle or Achilles tendon is tight, the surgeon may lengthen it in order to improve the ankle’s range of motion. The surgeon might use screws to stabilize the new joint and keep it positioned properly.
The operation takes between 60 and 90 minutes.
Recovery
The stitches are removed about 2 weeks after surgery. In the days when surgery, it’s necessary to keep your foot elevated the maximum amount as doable so as to cut back swelling.
For about 4-6 weeks from the date of surgery patient should not bear weight on his ankle. After that, he will be transition into a pneumatic boot (it looks like a ski boot with an inflatable liner for additional compression), and encourage to work on range of motion with the ankle. Around 3 months after your surgery, he will transition into a shoe with an ankle brace and may start non-impact activities.
After a year, most patients can return to low-demand activities such as walking, biking, hiking, swimming and using an elliptical trainer. Engaging in high-impact activities, such as running or other sports that have a lot of impact on the ankle, may decrease the life expectancy of the prosthesis in the ankle.
