Dicky, mostly afflicted, needs surgery (8)
I believe the answer is:
facelift
'surgery' is the definition.
(I know that facelift is a type of anaplasty)
'dicky mostly afflicted' is the wordplay.
'dicky' indicates anagramming the letters (dicky can mean ill or non-functioning).
'mostly' means to remove the last letter.
'afflicted' with its last letter taken off is 'afflicte'.
'afflicte' is an anagram of 'FACELIFT'.
'needs' acts as a link.
(Other definitions for facelift that I've seen before include "Cosmetic surgery" , "Renovation" , "wrinkle treatment" , "plastic surgery" , "surgical treatment" .)
