Compared to the wear a human body inflicts on a foot sole, a mechanical prosthetic not only wears down the metal at the foot sole, but also wears down the severed bone at the transplant site; in the short term this may not show anything, but over time the problem becomes serious.
The friction between metal and bone causes both to undergo secondary wear without anyone noticing; as time goes on, the gap between them widens, and accidents arise naturally.
At the same time, one has to mention that the water and oxygen in the blood within the human body are also accelerating the oxidation of the metal — this is a materials problem.
