摘要

Abstract Following anterior cruciate ligament (ACL) reconstruction limb dominance for performing tasks is not considered when making rehabilitation progression decisions. The purpose of this study was to determine if strength and functional outcomes differ between individuals who injured their preferred or nonpreferred jumping limb and to determine if these same outcomes differ between individuals who injured their preferred or nonpreferred limb used to kick a ball. A secondary purpose was to determine the association of quadriceps strength and single‐leg forward hop performance with patient self‐reported function. Forty individuals with ACL reconstruction (age?=?20.0?±?4.6?years, height?=?174.2?±?12.7?cm, mass?=?71.2?±?12.7?kg, time since surgery?=?5.3?±?0.8 months) were included in the study. Primary outcome measures included, International Knee Documentation Committee Subjective Knee Form (IKDC) scores, quadriceps limb symmetry index (LSI) values, and single‐leg forward hop LSI values. Limb preference was defined two ways, kicking a ball and performing a unilateral jump. There were no significant differences between groups based on injury to the preferred limb to kick a ball for any of the outcome variables. Individuals who injured their nonpreferred jumping limb demonstrated significantly (p?=?0.05, d?=?0.77) lower single‐leg forward hop LSI values (81.1?±?19.5) compared to individuals who injured their preferred jumping limb (94.1?±?12.6), but demonstrated no differences in IKDC scores or quadriceps LSI values. Quadriceps LSI and single‐leg forward hop LSI explained 73 of the variance in IKDC scores, but quadriceps LSI had the strongest association (r?=?0.790). These findings suggests that limb preference influences single forward hop LSI values and should be considered following ACL reconstruction.
