Implication

Randomized trial assesses gait kinematics in pediatric patients post-ACLR, highlighting rehabilitation needs.

Key Points

  • This study aims to evaluate the impact of ACL reconstruction on kinematic gait patterns in pediatric patients.
  • Participants aged 12–18 years with isolated ACL tears underwent pre- and post-operative 3D gait analysis.
  • Kinematic parameters were compared using SPM1d analysis across ACL-deficient, post-ACLR, contralateral, and healthy limbs.
  • Prior injuries and neuromuscular conditions were exclusion criteria.
  • Both ACLD and ACLR limbs showed increased knee flexion during 1–55% of stance phase versus controls (p=0.0001).
  • ACLD limbs exhibited increased external tibial rotation (13–18%) compared to controls, indicating a pivot-shift avoidance strategy.
  • No significant improvements in sagittal kinematics were seen between pre- and post-operative assessments.
