Associations Between Side-to-Side Differences (ACLR—Contralateral) in Kinematic Variables During Walking at Baseline Testing 2 Years Post-ACL Reconstruction and Changes in Lysholm and KOOS Pain and QOL Subscales From 2 to 8 Years Post-ACL Reconstruction

	Side-to-Side Difference (ACLR—Contralateral) in Kinematic Variable

Change in Patient-Reported Outcome Scale	Average KFA in Stance	Average VV Angle in Stance	Average IE Rotation Angle in Stance	Average Anterior FD in Stance
Lysholm	−0.30 (0.258)	−0.65 (0.006)	−0.37 (0.157)	0.58 (0.019)
KOOS pain	−0.20 (0.486)	−0.38 (0.165)	−0.15 (0.588)	0.31 (0.266)
KOOS QOL	−0.08 (0.768)	−0.15 (0.586)	−0.08 (0.795)	0.10 (0.731)

Pearson correlation coefficients (p-values) are presented. Bold indicates significance at the α =0.05 level. For kinematic variables, positive indicates flexion, varus rotation, external rotation, and anterior femoral displacement. KFA, knee flexion angle; VV, varus-valgus; IE, internal-external; FD, femoral displacement.
