I can actually think of a few things that would legitimately qualify for that. For example - a slight labral tear in the shoulder - does not automatically require a surgery. But depending on where the tear is, and how strong the muscles are around it, the person will feel a different impact. You see it all the time in professional sports where they wait until the offseason to get an operation. Certain things can be enough of a gray area, you could probably wrestle-off and get surgery if you lose.
