I will spare you the details of my injuries. Let it suffice to say that both knees got shattered. Took a long time, but now I am stronger than ever.
As soon as you can tolerate it, begin to stretch the ankle. As it heals it will easily become capable of bearing weight, the number one problem is avoiding a loss of flexibility. And losing flexibility in the ankle can limit you in many ways.
When you start walking again, do not limp, no matter how much it hurts. You can develop poor motor recruitment patterns that can affect your hamstrings and even your back.
I am sure you will do fine.
