Jannik Sinner spent ninety-five weeks ranked as the world number one before a right knee injury forced a prolonged absence from competitive tennis, leading to the loss of the top ranking to Alexander Zverev, as Il Messaggero reported.
The Italian player addressed his physical setbacks in a six-minute video titled “Jannik Sinner Unfiltered” posted to his YouTube channel, detailing medical consultations in France and a rehabilitation routine in Monaco, ANSA reported.
The video documents Sinner’s journey to Lyon to consult knee specialist Dr. Sonnery Cottet, accompanied by physical trainer Umberto Ferrara, with orthopedic surgeon Herbert Schoenhuber also visible in the background, Corriere della Sera reported.

Following the Lyon visit, Sinner returned to Monte Carlo to focus on rebuilding muscle mass through daily physical therapy and strength exercises.
In addition to managing the right knee tendon issue involving the iliotibial band, Sinner revealed that he underwent surgery to remove his tonsils, an adult procedure that caused significant weight loss and a noticeable change in facial appearance, ANSA reported.
«Adesso lavoriamo ogni giorno cercando di ricostruire la massa muscolare. Qualche settimana fa mi sono tolto le tonsille e ho perso parecchio peso. Forse si vede anche dal viso, che è piuttosto scavato.
A tonsil infection previously forced Sinner to withdraw from the Paris 2024 Olympic Games.
As Sinner prepares for the upcoming season, coach Darren Cahill reflected on the mental demands of the sport before concluding his five-year tenure with the player at the end of 2026, Il Messaggero reported.

«Nel tennis devi sempre assicurarti di essere al cento per cento.
E poi penso che, quando ricomincerò in Australia, davanti a un po’ di tifosi, sarà bellissimo,» said Jannik Sinner.
