19 of Medvedev's 21 championships have been achieved on hard courts
A comeback Medvedev claimed his first championship for 882 days with victory over Frenchman Moutet in the tournament championship match.
The Russian, a former number one, has endured a torrid period, winning just a single victory at the major tournaments and experiencing a setback at the US Open.
His varied form on the professional circuit - and issues with his serving in specific - resulted in him falling of the elite rankings and ultimately separating with former mentor Cervara.
Currently working with Johansson and Rohan Goetzke, he has steadily advanced in the last few weeks - culminating in a closely contested three-set triumph over opponent Moutet.
It is the player's first title following the Rome competition and first on a hard surface from that period of that year.
The win also means Medvedev has achieved 21 titles at 21 distinct competitions.
"It's the first time I'm at a competition with my two daughters together, so to get a trophy is really nice," said ranked player Medvedev.
"This title is in tribute of my younger daughter her name, because the initial championship I got when my older daughter her name was born was for her."
The athlete, the 2021 US Open champion, had lost his previous six championship matches, featuring in the German tournament in the past months.
Medvedev's defensive strategy and regular outbursts on the tennis court had caused commentators to question if his ability to compete at the elite level was concluded.
Yet the 29-year-old has altered his approach in the last few weeks, attempting to advance forward and play assertively, reinforced by an better service.
Medvedev came back from a disadvantage in the first set against the difficult opponent, taking 4 of the final five points to gain the advantage.
The pair exchanged breaks in the second set before the Frenchman, attempting for his maiden professional title, seized the initiative to force a third set.
The opponent defended four early-game opportunities in a competitive final set before the Russian broke to fifteen to close out the victory.
Appropriately, the winner earned the win with a point at the front of the court, with Moutet unable to control a return after two hours and 38 minutes.
