The 28-year old was allowed home to the Ivory Coast to continue his rehab, with the blessing of the coaching staff.
Now, the Ivorian is keen to get back and perform on the pitch in order to repay that trust placed in him.
"The club and the gaffer trust me," Gradel said.
"They didn't have to let me go home so to for them to do that means a lot to me.
"I had some time to see my family, it was a good time to see them but it was hard being away from my team-mates. It is very important to be happy while you're doing your rehab too, it was hard work but I had my family around me.
"The fans have been great with me, sending my lots of positive messages. I'm so happy to be back, it's a good feeling and now I want to get fit and give my all on the pitch to repay the faith put in me."
Back at the club, Gradel reflected on a tough time since he injured his knee back in August.
Besides from reflecting on a negative time in his career, the winger is looking forward to the future and has the strong belief that the Cherries will stay in the Barclays Premier League this campaign.
"It was a hard time of course," Gradel continued.
"You have to think positively, of the good times, to make you feel stronger. I thought back to when I won the African Cup of Nations, thinking of the day we won it and the day we went home and everyone was on the street going crazy.
"Things like that give you the strength to step up and carry on.
"The club sent me every game on email so I’ve been watching the games and I've been impressed. The players have been developing so well and we've signed some very good players too.
"We've been on a good run and have to keep that going. When I see how the team play at the moment and the players we've brought in, I'm confident that next season we'll be in the Premier League.
"The club moving in the right direction."
