The Queensland Reds player underwent surgery to repair a torn anterior cruciate ligament on Saturday, and will begin his rehabilitation as soon as possible under the guidance of Wallabies physiotherapist and former international prop Cameron Lillicrap.
If Latham is to return to the international stage in June, he will have played just three Tests before the start of the World Cup in September.
But Connolly believes the timetable is a realistic one for the 72-Test veteran.
"We're aiming for the first All Black Test, which is just inside six months," Connolly told the Sunday Mail.
If everything goes to plan, Latham will miss the opening Tri-Nations clash in South Africa, but will then be available for two matches against the All Blacks and one against the Springboks before the World Cup commences.
