'condition' is the definition.
(fettle is a kind of condition)

I don't understand how the rest of the clue works.

(Other definitions for fettle that I've seen before include "Condition (usually fine)" , "Be in fine . . . . . . to be in good condition (6)" , "Condition, trim - sometimes fine" , "A state of fitness and good health" , "Be in fine . . . . . . to be in excellent form" .)

I've seen this clue in The Independent.
