I'm looking at my wife's prosthetic leg as I write this. I'm not in a position right now to take a picture of it, but it is what it is. She's slowly learning to walk with it, but the skin on her stump has to toughen up some more. It all takes a lot of time. She goes to physical therapy twice a week now where they have her walking on it for about 45 minutes. She can wear it for a half hour a day at home. Eventually the time worn will get longer. She's hopes to be walking on it by the time our son gets married at the end of March.
I have a knee brace that I have to wear do to a major injury and knee surgery a couple years ago.
