Hoshi Tore His ACL. So What Happens Now?
So, Hoshi tore his ACL.
On September 12, Hoshi shared on Weverse that he injured his knee during rehearsal with the Ground Forces performance team and was subsequently diagnosed with a complete anterior cruciate ligament (ACL) tear. He will undergo surgery and focus on treatment and recovery for the time being, meaning he will miss his upcoming commitments with the Army Taekwondo Demonstration Team and the Ground Forces Festival.
And because his discharge was originally expected around March 2027, he had roughly six months of military service left.
Naturally, CARATs are spiraling with questions.
How does something like this happen during a rehearsal?
Was the military workload simply too much?
Can he leave early?
Why are Korean CARATs asking for a civilian hospital?
And perhaps most painfully:
What does this mean for Hoshi as one of SEVENTEEN's central performers?
Let's actually break it down.
1. How the hell can Hoshi tear his ACL during “just a rehearsal”?
The first thing to understand is that an ACL does not need a collision, tackle, or spectacular accident to rupture.
The anterior cruciate ligament is one of the major stabilising structures of the knee. It helps control forward movement of the tibia relative to the femur and contributes significantly to rotational stability.
And ACL injuries can happen without another person touching you.
Non-contact mechanisms are particularly common in sports involving jumping, landing, rapid deceleration and sudden changes of direction. Dance is a surprisingly good example.
A five-year prospective study of elite ballet and modern dancers found that 92% of the ACL injuries observed occurred during single-leg landings after jumps. The researchers also found evidence suggesting that fatigue may contribute to injury risk.
That is important because people sometimes hear “rehearsal” and imagine something relatively gentle.
But a rehearsal can involve hundreds of repetitions of movements that place substantial loads on the knee:
- jumping;
- landing on one leg;
- pivoting;
- rapidly stopping;
- changing direction;
- rotating while the foot is planted;
- and repeatedly absorbing body weight through the same joints.
Taekwondo adds another layer of explosive kicking, jumping, rotation and landing.
The actual injury mechanism can be remarkably unremarkable from the outside.
There may be no dramatic crash.
Sometimes it is simply:
plant - decelerate/rotate - knee moves outside its optimal alignment - ACL fails.
So yes, someone can genuinely tear their ACL during what looks like “just another rehearsal.”
That doesn't tell us exactly what happened to Hoshi. We don't have the specific movement, video, imaging details or biomechanical analysis.
But the general mechanism is absolutely plausible.
2. Was the military workload excessive, and could this have been avoided?
This is where I think it is completely fair to ask questions without pretending we already know the answer.
Hoshi wasn't simply doing ordinary military activities.
He had been serving with the Army Taekwondo Demonstration Team, while also preparing for the Ground Forces performance. His injury reportedly occurred during rehearsal for that performance.
And honestly, I understand why people are looking at this and going:
Why the ever-loving fuck was he still doing all of this?
He had already spent months serving in a physically demanding role. He was preparing for another military performance. He was also approaching the final part of his service.
Saw this edit on IG and it is heartbreaking to watch 😣 his knee alr got injured but he still performed 100% 😣
He's been practicing nonstop not only for the Army Taekwondo Demonstration Unit but also for the Ground Forces Festival. He worked SO HARD 😣
fun fact: it was mingyu himself who came up with his fans’ name “gyuldaengie” 🐶
during a fansign in 2019, a fan asked mingyu what his fans should be called, and he wrote “귤댕이” (gyuldaengie) on their album.
“귤” (gyul) is a cute way of calling gyu (it also means “tangerine” in korean, which fans originally started using to refer to mingyu bc of his naturally warm, golden skin tone)
meanwhile, “댕이” (daengie) is short for “댕댕이” (daengdaengie), an internet slang for “puppy”
so “귤댕이” means we’re mingyu’s puppies 🥰
when seventeen did a surprise raffle for their staff with prizes that each member personally contributed. such a sweet gesture that shows how much they truly appreciate the people who work alongside them. really says a lot about the kind of people they are
