Implication

Examines biomechanical differences following ACLR in youth, suggesting unique gait patterns and implications for knee health.

Key Points

  • To characterize gait biomechanics in pediatric ACLR patients and compare these profiles with controls and adult ACLR patients.
  • Compared gait biomechanics across three groups: pediatric ACLR, pediatric controls, and adult ACLR.
  • Collected data on vertical ground reaction forces and knee angles during walking.
  • Analyzed associations between biomechanical data and KOOS-Child outcomes using partial correlations.
  • Pediatric ACLR patients showed lesser vertical ground reaction forces compared to both control groups.
  • Pediatric ACLR exhibited a different knee flexion angle throughout the gait cycle compared to controls and adults.
  • Greater midstance vertical ground reaction force was linked to improved quality of life scores in the contralateral limb.
