I know the best solution is to plan for knee replacement surgery. It’s never going to be convenient, but one should have the surgery on one’s timetable before the knee becomes unusable or usable only with debilitating pain.

That’s not my question.

Instead, what happens when a knee fails? Is it immediate?

I need a new knee. The pain is worsening by the month, but I can still do most things. I would like to hear how your knee “failed” or when it was obvious you must have it replaced.
