The France striker suffered a damaged left tibia in a 2-2 Premier League draw at Everton back in August and underwent surgery four days later.
Giroud was expected to return at the end of December, but Arsenal manager Arsene Wenger last month revealed that the former Montpellier frontman was ahead of schedule with his rehabilitation.
Wenger has had to contend with long-term injuries to Mesut Ozil, Mathieu Debuchy and Laurent Koscielny this season, while Theo Walcott has not yet started a game since his comeback following a serious knee injury.
Danny Welbeck has led the line in the absence of Giroud, while Alexis Sanchez has been prolific since his move from Barcelona but Wenger has limited attacking options in his squad so Giroud's return to fitness will be a major plus.
