What Happens During Ankle Replacement Surgery?
It’s the same idea as having most things fixed – worn parts are taken out, and new parts are installed in their place. In surgery, the damaged portions of the lower end of your shin bone (tibia) and the top of your foot bone (talus) are removed. Through a lateral approach, the metal parts of the Zimmer Trabecular Metal Total Ankle implant are attached by placing them tightly against the bones and utilizing special cement to fix portions of the components to the bone. To finish, the fibula will be repositioned with a metal plate and the incision is closed.
What Happens Afterward?
Considering the complexity of your surgery, your doctor will give you specific instructions on wound care, pain control, and when you can resume other activities like walking with both feet.
Generally after surgery, you will be in a well-padded splint for the first 2-3 weeks. You can use a wheel chair or crutches during this time. After that you will transition to a boot, but you will still need to use crutches or a roll-about until your doctor gives you permission to put full weight on your ankle.
