Note
Visited physio - haven't exactly followed the exercise plan to the letter over the last 4 weeks but I've been working the ankle fairly hard none-the-less. It's understandable that once I was actually allowed to actively use the joint that I basically have been at every opportunity, constantly playing with it! Plus...
It was a consideration that we were moving house at the end of January when they offered me the operation, 2.5 months probably just enough time post-op to be able to do it without risking the ankle too much. We had lots of help and I put the boot on to help whenever I was working indoors. Also took regular breaks and iced it a lot.
So the end result is that progress is good and I have a new set of harder exercises to take away with me.
