They say it takes 30-50% more energy to walk for each joint that you are missing. The biggest problem now is that if they try to make these things powered the batteries and electronics just weigh too much. The one powered foot I tested last year weighed 9 lbs. So slap a 10 lb weight on your ankle and go walk around with it. You loose those muscles in your calf with a below the knee amputation.
The C-Leg which is the most advanced knee right now weighs 15-18 lbs depending on which foot they put with it. As lithium battery technology improves the weight of these prosthetics will go down. And this is part of the reason why I volunteer for these studies. I'm hoping at some point I might get to get to wear some new foot that they come out with.
I use to snow ski and Ottobock makes a foot that is made to clip into the ski bindings instead of having to wear that heavy ski boot. It's pretty cool and the VA has said they might send me to a winter sports event for amputees. Of course Covid has "F"d that all up right now.
