All data reported as mean (95% Confidence Interval)
RTS-PASS=ACLR cohort that passed return to sport criteria, RTS-FAIL=ACLR cohort that failed return to sport criteria, CTRL=uninjured control group, IC= Initial Contact, WA= Weight Acceptance, KFA= Knee Flexion Angle, vGRF= Vertical Ground Reaction Force, KEM= Internal Knee Extension Moment,
a
Indicates a statistically significant main effect for limb
b
Indicates a statistically significant group x limb interaction, see Figure 1 for additional comparisons
