I was just literally reading ankle rehab exercises, the tab is still open on my laptop. I suffered the same fate just before Christmas, surgery took a while to arrange due to the holidays, but I also added to my titanium hardware collection. Now two months in, I just graduated from my walking boot, and will start PT next week.
I have been doing some home exercises while I've been down. Mainly upper body and core, since as a cyclist that sometimes get neglected, and I'm happy to say I notice some improvement. I'm looking forward to start spinning the pedals again though.
You, on the other hand, are going to have to take it easy for now. After your surgery dressing comes off, you may feel like you can start messing around, but I recommend you don't. You can start moving the ankle around a bit, but don't try to ride on it.
I did a ten minute roller ride after getting out of my cast. It felt fine, no pain, but later that day my foot really swelled. So try to be patient, and I wish you a speedy recovery.
