Sinner's knee pain continues

Jannik Sinner, the world number one tennis player, has been absent from the sport for an extended period due to recurring knee pain. Former American coach Brad Gilbert, who is close to Sinner's coach Darren Cahill, has expressed concerns about the player's condition.

Treatment without surgery

Sinner has opted for a treatment plan that avoids surgery, following advice from multiple doctors. He has been taking rest days and has been avoiding intense training sessions, but the pain returns when he increases the intensity of his workouts.

Uncertainty about future training

Gilbert has suggested that if Sinner's knee pain continues into December, when he would need to intensify his training for the Australian Open, surgery might become an option. While surgery is generally avoided, modern knee procedures are less invasive than they were 30 years ago.

Cahill's role in the team

Beyond the physical concerns, Gilbert has raised questions about the role of Darren Cahill in Sinner's team. He mentioned that Cahill was informed late about Sinner's decision to withdraw from the Cincinnati Masters 1000, which disrupted Cahill's travel plans.

Communication issues

Gilbert reported that Cahill learned of the withdrawal while preparing to fly to Cincinnati. He was supposed to meet Sinner at the Los Angeles airport but received a last-minute call saying Sinner would not participate. Since then, Cahill has been waiting for updates, which has caused frustration.
