Both ACL-RSI and K-SES at 3 months were predictive of the IKDC score at 6 months (R2 = 0.411; p = 0.001).

Why the study?

It was unknown whether psychological readiness for sport and knee self-efficacy assessed at 3 months after ACLR predict self-reported functional outcomes, quadriceps strength, and knee running mechanics at 6 months.

Do psychosocial factors at 3 months after ACLR predict 6-month subjective and objective knee outcomes in athletes?

Comparison

Overview

Early ACL-RSI/K-SES scores may aid 6-month RTS prognostication after ACLR; leaves open whether interventions targeting them improve outcomes.

Structured PICO

Do psychosocial factors at 3 months after ACLR predict 6-month subjective and objective knee outcomes in athletes?

P
Population
30 athletes with unilateral anterior cruciate ligament reconstruction (ACLR)
I
Intervention
Psychological readiness for sport (ACL-RSI) and knee self-efficacy (K-SES) assessed at 3 months after ACLR
O
Outcome
Self-reported functional outcomes (IKDC, KOOS), isometric quadriceps strength, and three-dimensional running gait analysis at 6 months after ACLRpatient reported

Psychological readiness and knee self-efficacy at 3 months post-ACLR predict better self-reported functional outcomes, quadriceps strength, and knee mechanics at 6 months.
