Distention following injury causes tissue inflammation (10)

I believe the answer is:

tendonitis

I'm a little stuck... Click here to teach me more about this clue!

'inflammation' is the definition.
(I know that tendonitis is a type of inflammation)

'distention following injury causes tissue' is the wordplay.
'distention' can be anagrammed to 'TENDONITIS'.
Though, I'm unsure how the anagram is indicated.

Can you help me to learn more?

(Other definitions for tendonitis that I've seen before include "painful affliction" , "Painful condition" , "pain" .)

I've seen this clue in The Independent.
