SEVENTEEN’s Hoshi Suffers Complete ACL Tear, Faces Surgery and Long Recovery

SEVENTEEN’s Hoshi is facing a lengthy recovery after suffering a complete tear of his anterior cruciate ligament (ACL) during rehearsals for a military performance. The injury has forced the singer to prepare for surgery and is expected to keep him away from activities for a significant period, creating another difficult moment for CARATs during SEVENTEEN’s ongoing military-service era.

Hoshi reportedly injured his knee while rehearsing with a military performance team. Following the incident, he underwent a detailed medical examination and was diagnosed with a complete ACL tear. The injury is considered serious enough to require surgical treatment, meaning his recovery will likely take months rather than weeks.

The timing makes the situation particularly significant for SEVENTEEN. The 13-member group is already navigating a complicated period as multiple members complete South Korea’s mandatory military service. Hoshi himself began his military service earlier this year, meaning fans had already been adjusting to seeing the group operate without its full lineup.

Hoshi is one of SEVENTEEN’s three principal performance leaders and a central member of the group’s Performance Team alongside Jun, The8 and Dino. He is also known for his unusually intense approach to choreography and performance. His stage presence has become one of the defining characteristics of SEVENTEEN, while his creative involvement has extended beyond performing.

The injury therefore affects more than a single schedule. Military performances require physical preparation, and an ACL injury can significantly restrict movement even after surgery. Rehabilitation typically involves gradually rebuilding strength and stability before an athlete can safely return to demanding physical activity.

For SEVENTEEN, the development arrives after an already complicated year. The group’s members have continued releasing music and pursuing individual activities while military enlistments temporarily divide the team. Their ability to maintain a strong group identity despite those absences has become an important part of the current SEVENTEEN story.

Fans will understandably be concerned about Hoshi’s recovery, but the priority now is his health rather than a quick return to the stage.

The exact surgical date and recovery timeline have not yet been fully detailed in the available report.

What fans can expect next: Further updates are likely to focus on Hoshi’s surgery, rehabilitation and eventual return to activities. For now, CARATs will have to wait for medical updates rather than a performance schedule.
