Juan Martin del Potro will launch his latest comeback at the Delray Beach Open in Florida later this month.
The 27-year-old Argentine shocked Roger Federer to capture the US Open title in 2009, but has been dogged by wrist problems ever since, requiring three operations to repair the damage.
He played only three tournaments in 2014 and just two in 2015, the last of which was in Miami in March, and his world ranking has slumped to 1,041 - he was the world No 4 after winning in New York - as a result.
"I wanted to share the moment and happiness that I feel knowing I will play on a tennis court once again after such a long time," Del Potro, who has won 18 ATP Tour titles, said in a three-minute video message posted on his Facebook page.
"The uncertainties, all the bad moments I had to go through, the many mood swings and really difficult days that make you think about giving up.
"But I have good people who would not let me fall. They were there at the right moments, supporting and helping me.
"They ruled out all thoughts of retirement; they always encouraged me."
The Delray Beach Open takes places from February 15-21.
