Partey has been restricted to just six matches for Arsenal since arriving from LaLiga side Atletico Madrid in a £45million deal three months ago.
Only one of those appearances has come in the last two months, having aggravated a thigh injury in Arsenal's 2-0 loss to London rivals Tottenham in December.
However, Partey is back in contention for Thursday's Premier League clash with Crystal Palace and Arteta is excited to be able to call upon one of his key men once again.
"I think he's got a different presence - he brings something different to the team," Arteta said. "It's not just about his talent, it's not just about his physicality, it's who he is as a person.
"He makes players better around him and that's a big, big quality.
