Table 4.
Sagittal plane interlimb asymmetries (determined by the difference in the mean values of the uninvolved and involved limbs for each group) exceeding MCID values [31] existed across both groups, as indicated by the check marks (√)*

*Note the larger number of asymmetries that was present at 1 versus 2 years postoperatively; MCID = minimal clinically important difference; SAP = strength, agility, and secondary prevention treatment group; SAP+PERT = SAP + perturbation training group; pKFA = peak knee flexion angle.
