She knew this day would come when she chose to play a style of badminton like a man.She tio ACL injury, sipeh jialat..same case as mine but mine was left knee during a tournament... it was so painful I was down on court for 10 mins cannot even move. Have to go for knee surgery and long term therapy but can no longer play competitive badminton.
The coach is to blame for encouraging her to move in that direction.
The proper way to play ladies badminton is to play like Rachanok Intanon.
