Values are median (IQR). All questions are rated on a 1–7 Likert scale from 1=low/do not agree/inadequate to 7=high/agree/adequate. Groups are based on whether the respondent had used Knee Control+ (users Knee Control+), Knee Control or the 11+ (users other IPEP) or if they had not used a complete injury prevention programme during the 2021 season (non-users). Non-users did not use a complete injury prevention programme but many used some exercises.
