Abstract.

We measured torque curve pattern and quadriceps muscle strength with the knee slightly flexed in 48 patients with an anterior cruciate ligament injury, and analyzed the factors associated with reduced quadriceps strength. Strength was measured under isokinetic contraction, and concentric and eccentric contractions were studied. Strength was significantly lower in the injured knee, which also showed abnormal patterns of torque curve. In addition to the rapid downward slope pattern usually associated with concentric contraction, there was a concave pattern during eccentric contraction.

Résumé. Nous avons mesuré le moment de rotation et la force du quadriceps à la flexion légère du genou chez 48 malades ayant une lésion du ligament croisé antérieur (ACL), et a analysé les facteurs associé s à l'affaiblissement de la force quadricipitale. La force des quadriceps a été mesurée sous contraction isocinétique, et les contractions concentriques et excentriques ont été étudiées. La force des quadriceps était considérablement inférieure sur le genou blessé comparé au genou opposé, indemne . Le genou blessé a aussi montré des modèles de moment de rotation distinct des modèles normaux. En plus de la rapide décroissance habituellement rapportée pendant la contraction concentrique, un modèle concave a été observé pendant la contraction excentrique.
