Mean data reported as a percentage of body weight × height for ACL reconstructed (ACLR) knees, non-reconstructed contralateral knees, and healthy control knees, with regions of statistical significance (p < 0.05) indicated: ACLR vs. control [*], contralateral vs. control [+], ACLR vs. contralateral [^].
