Wow that image looks completely primitive, like something out of Bioshock. I’m actually surprised our medical system is not able to do something better than that.
Natural isn't good. Rotationplasty is way, way better than any of the alternatives (amputation, transderal prosthesis etc). It involves reattaching the foot to the knee backwards so that the ankle acts like a new knee.

You walk almost naturally and keep more strength than any electronic prosthesis. It's has less pain than an amputation and no phantom limb sensation. It may look primitive, but it's far and away superior to anything else right now.
