Table 3 Raw Isokinetic strength values (normalized to bodyweight). Isokinetic strength values for ACL-R (anterior cruciate ligament reconstruction) participants with Q-LSI (quadriceps limb symmetry index) < .90, ACL-R participants with Q-LSI ≥ .90 and healthy controls. The p-value indicates significance for the group comparison between those that achieve relative quadricep strength symmetry and those that do not, and the effect size indicates the strength of this difference. interpreted as small (0–0.39), moderate (0.4–0.69), and large (0.7 or greater).
