Table 3 Between-group comparisons based on group medians (Quartile 1, Quartile 3) for knee abduction maximum, knee adduction maximum, knee abduction/adduction range, and knee movement units in the frontal plane during the Rise and Down phases of the One-leg rise. P-values (p) and effect sizes (r) are provided for all significant results

From: One-leg rise performance and associated knee kinematics in ACL-deficient and ACL-reconstructed persons 23 years post-injury
