What can cause tpr?

I’m relatively new to fostering. I’ve had a few placements pulled from their homes do to drug use and I’m aware that sometimes the court comes up with an in home plan or a plan for the parents to get things back on track before the child can go back home. My most recent placement was pulled due to abuse in the home but no concerns of drugs. My question now is can a child ever go back to their home if they were pulled for physical abuse?
