Unlike how easily it is depicted in medias, full-skeleton replacement won't be happening anytime soon, if ever. The main issue with the process would be how to detach and reattach muscles from the original skeleton to the new artificial skeleton, not to mention more delicate organs and tissues like mucosal membranes and the likes.

I'd argue you'd have to use nanite-based technology to reattach the fleshy parts of the body on a near molecular level in order to safety replace a human skeleton with a robotic one.
The other problem is that bones are responsible for growing blood cells and assigning them to the body. A robotic skeleton would need to also have an onboard bone marrow factory and a stem cell processing plant. It would take a massive leap in biomechanical engineering, robotics, and pharmaceutical science before we are close to making something like that.
