The athlete entered the previous US Open as the 26th seed.
Stefanos Tsitsipas has revealed he thought about ending his career because of debilitating back issues during the season.
At 27 years old, the player once ranked as high as third globally, was a finalist against Novak Djokovic in the finals of the 2021 French Open and the 2023 Australian Open.
Currently placed 36th in the world following minimal competition since his early exit in New York this past summer, Tsitsipas indicated that ongoing treatment is finally showing positive results.
"I'm most excited is to observe how my training holds up under actual training concerning my back," commented Tsitsipas.
"The biggest fear was whether I could complete an encounter," the athlete continued, explaining the pain had troubled him "for the past six to eight months."
"I kept asking, 'Am I able to play in another match without discomfort?'"
"It was genuinely scary after the defeat at the US Open [to Germany's Daniel Altmaier]. I could not to walk for two days. That's when you begin to question your career's future."
He also reported being content with his current recovery plan following the completion of an extended period of off-season preparation completely pain-free.
He is scheduled to compete for Greece at the team event, where they face Naomi Osaka's Japan and the British team captained by Raducanu. The competition takes place in Perth and Sydney in early January, just before the season's first major.
"The greatest victory next season is to not have concerns about finishing matches," he stated.
"It is incredibly encouraging to know you completed a pre-season in good health – I hope it continues. I aim to perform during the upcoming season and for the team championship.
"The effort is invested. The crucial element is total belief that I can return to where I was. I will try all means to make it happen."
