'joint complaint' is the definition.
'rheumatism' can be an answer for 'complaint' (rheumatism is a kind of disease). I'm not sure about the 'joint' bit.

'hear summit overturned' is the wordplay.
'overturned' indicates an anagram.
'hear'+'summit'='hearsummit'
'hearsummit' with letters rearranged gives 'RHEUMATISM'.

Can you help me to learn more?

(Other definitions for rheumatism that I've seen before include "ailment" , "Joint affliction" , "Inflammation of the joints" .)

I've seen this clue in The Times and The Sunday Times.
