  1. ACL injury refers to patients treated with rehabilitation, ACL reconstruction refers to patients treated with reconstruction and rehabilitation, K-SES18 the 18-item version of the Knee Self-Efficacy Scale, RTS returned to sport (defined as present level of physical activity as measured with the Tegner activity scale being ≥ to the level the patient had before the injury)
  2. *follow-up performed within 6 weeks before ACL reconstruction, ap < 0,001, 4 months vs 12 months, bp < 0,001, returned to sport vs not returned to sport
