SD standard deviation, IKDC-SKF International Knee Documentation Committee Subjective Knee Form
^aFor the IKDC-SKF, sample size for Follow-up was n=16 for the Control Group and n=15 for the Sleeve Group
**For hop distance, quadriceps and hamstrings peak torque, interaction effects for injured leg with sleeve at follow-up (three-way interaction) and interaction effect for sleeve at follow-up (two-way interaction) are presented as ratios of the geometric means
