The purpose of this study is to characterize quadriceps function and squat biomechanics during the early strengthening phase in adolescent patients undergoing a standardized combined neuromuscular electrical stimulation (NMES) and blood flow restriction (BFR) rehabilitation protocol

NMES is applied when patients perform quadriceps strengthening exercises. BFR is applied during compound exercises.
Standard physical therapy (week 1-16) includes interventions for typical impairments following ACLR. The initial phase will focus on pain and effusion control, restoration of knee range of motion, followed by gait normalization, lower extremity strength training, then running and plyometrics.
