The Gunners' club-record signing suffered a partial rupture of the outer band of the left knee joint, which was confirmed by the German Football Federation after Ozil reported for international duty following Arsenal's 2-0 defeat at Chelsea on October 5.
According to the DFB at the time, Ozil would be out for "10 to 12 weeks".
Arsenal subsequently released their own statement insisting no time frame had yet been set for the recovery, which added "(manager Arsene) Wenger knows he will be without Ozil for at least two months".
Ozil was attending the Laureus Media Prize ceremony in Berlin on Wednesday, where he received an award after paying for 23 Brazilian children to have life-saving surgery, and confirmed his return was not expected until mid-January.
"I have already been out for five weeks and will be out for another seven weeks," Ozil said.
"That is a really long time, but that is the way it is in football sometimes
My head is held high and we look forward."
Arsenal have taken on board the information provided by the DFB, but have also conducted their own investigation, with Wenger stressing at the time of Ozil's injury they would have to be patient.
"We have our own specialist giving us his opinion after reading the scan and examining Mesut
We will follow our own recommendations," he said.
Press Association Sport understands Arsenal remain confident Ozil's recover is on schedule, with the plan always for a return early in 2015.
Despite the form of summer signing Alexis Sanchez, Arsenal have struggled for consistency this season, slipping to a 2-1 defeat at Swansea on Sunday which left them sixth in the Barclays Premier League - once again having failed to hold on to a lead after being unable to press home their 3-0 advantage in the Champions League tie against Anderlecht
