My ankle was swollen for few weeks after the surgery. Few days after the surgery I forgot to use the compression sleeves, on the operated leg and it really swelled up. I called my doctors office to see if it was normal. They ignored my question completely and asked my about my calf instead. She told me if it’s tight and hurting go to the ER and get checked for a possible blood clot. Luckily, it only cost me the ER fees, and no clot. So please make sure that you rule out the blood clot.
As for as walking is considered, just watch any 4 year old kid to see how they walk. They don’t use heel to toe, instead it’s the whole foot forward and they never straighten their knees. Following that method I was able to walk few miles a day before my tkr, instead of few hundred feet with a bone on bone knee which was completely worn out. This is also called CHI walking. I tried to find a good link for chi walking but unfortunately couldn’t do so. There are too many people pretending to be the experts on the topic with crazy videos.
I’ve told by some serious marathon runners at the gym that they use the whole foot, not the heel to toe.
