Limb Symmetry Index (LSI) was used to express side-to-side differences in per cent using the non-injured leg as the control.

Quadriceps strength and lower-extremity performance were impaired for the injured leg compared with the non-injured leg (p&lt;0.001), with a mean difference of 13% in quadriceps strength and between 8% and 13% in lower-extremity performance.
