Abstract

The purposes of this study were: (1) to investigate the relationships between isokinetically tested quadriceps femoris and hamstring strength, the subjects' self-assessment of knee function, and three functional tests, and (2) to determine the strength and functional differences between the surgical and non-surgical limbs. Subjects included 18 males and 27 females aged 18 to 45 years who had undergone anterior cruciate ligament reconstruction. Knee strength was measured at 180, 300, and 450{dollar}\sp\circ{dollar}/second and normalized to body weight, while functional hop data were normalized to height. Significant differences existed between limbs for the single, triple, and cross-over hops, and all, but one, isokinetic extension variable. Moderate to good correlations were found between knee extension values and the single, triple, and cross-over hops. Fair correlations were noted between knee flexors and the triple and cross-over hops. Results suggest clinicians should use both strength and functional measures to determine return to activity.
