The Italy international has been restricted to just 20 minutes of action this campaign after a horrendous run of bad luck which has seen him suffer a number of injury setbacks.
Now he has revealed he is to undergo surgery to hopefully end his nightmare.
"We are currently trying to solve some problems I have had," he told Sky Sports Italia.
"Luckily I have received the support of my team-mates and the fans. I want to thank them because I wouldn't have been able to carry on without them.
"I have relapsed four times in my rehabilitation, so I think there will have to be a small operation."Hopefully, once that's done, I can return to playing as soon as possible."
The 29-year-old made his only Serie A appearance in the 0-0 draw with Lazio in November.
