He was forced to undergo two operations on the problem and has taken his time to ensure he’s followed the correct rehabilitation programme.
His season is due to get underway on March 8 but he is also expected to feature in Dubai the following week from March 14.
Federer is delighted to finally be heading on tour, as he explained in a video message on Twitter: “So here we are, about to take off for my flight to Doha.
“It’s been a long and hard road, so I’m not at the finish line yet. But it’s good you know. I feel like I’m in a good place, I’ve been practising well.
“Just really pumped up, I hope you guys are going to tune in to watch it.
“I hope I see you again very soon. Take care everybody.”
He is due to return home from the Middle East later this month, in order to give his knee some time to recover before the clay season begins.
Speaking to Bernhard Schar last month, Federer outlined his plans to return in Doha and admitted that his knee now feels much stronger.
“I am satisfied that I can say that I will try again in Doha,” he said.
“I thought about it for a long time, but Australia came a little early for me. I also wanted to come back to a smaller tournament, not the Australian Open. In Doha, the stands will probably be empty.
“I’m not at 100 per cent yet, but almost. That’s why I dare to go back on the tour. I do my sprints, play my training sets. I feel strong, better than in November and December when there was a lot more uncertainty.
“It was important that there had been no setbacks in the past six months. There was always progress, that was positive. I forced the knee, I had to do that too. Now, for the first time, I feel strong enough to take part in a tournament.
“With the stress and the adrenaline, it’s a completely different world.”
