The article discusses infection risk. Infection risk is an inherent part of the total risk associated with any medical procedure. It is not separable -- you cannot use an implant if it is not implanted.
Infection always has and likely always will be a risk when you open up a human. Evaluating, understanding, and measuring those risks is the only way we can begin to mitigate them.
On the bright side, recent medical technology has also brought us a lot of minimally or non-invasive procedures. Those generally have much lower (sometimes almost zero) risks of infection.
