Opposite to my previous standpoint, I'll share my experience briefly so far, to write as objectively as possible.
All went fine so far, I'm doing TSF-tibia 5 cm with Giotikas in Athens. I'm at post op day 3, pain comes and goes, I was standing on my feet with walker yesterday, today was walking already a bit (very slowly, and carefully). The frame is quite heavy, didn't expect it, and I think my muscles are not really built enough just to handle it easily. Knee flexibility is quite good, toes-ankles too, however I feel, that my ankles are quite weak (had injuries when I was younger and playing soccer, mainly sprain, some partial tear), and sore, however I know I'm only post op day 3, still would like to make sure is stable, as lengthening will start in couple of days.
Any opinion experience guys, how to strengthen ankles (the feeling is a bit burning-tiring feeling mixed with a slight spraining sensation when stretched, or dorsiflexed)?
