Abstract
We measured muscle strength in 36 patients after anterior cruciate ligament (ACL) reconstruction with autogenous bone-patellar tendon-bone graft. Quadriceps and hamstring isokinetic strength was assessed during concentric contraction at 60 and 180°/s and was measured at 1, 6, 12 and 24 months postoperatively. At 24 months quadriceps muscle strength had recovered to approximately 90% of the level of the uninvolved side, both at 60 and 180°/s. In contrast, hamstring muscle strength had already recovered to approximately 90% at 6 months. Age, gender, activity level, and anterior tibial laxity did not affect the muscle performance. However, the recovery of muscle strength was delayed in patients with anterior knee pain.
Résumé
Nous avons mesuré la force musculaire chez 36 malades après reconstruction du LCA avec auto- greffe "os-tendon rotulien-os". La force isokinétique du quadriceps et des ischio-jambiers a été étudiée pendant la contraction concentrique à 60 et 180 degré/sec et a été mesurée à 1, 6,12 et 24 mois postopératoires. À 24 mois la force musculaire du Quadriceps avait retrouvé approximativement 90% de la force du côté opposé, à 60 et 180 degré/sec. Par contraste, la force musculaire des ischio-jambiers avait déjà retrouvé 90% de sa valeur à 6 mois. L'âge, le sexe, le niveau d'activité, et la laxité tibiale antérieure n'ont pas affecté la performance musculaire. Cependant la récupération de force musculaire a été différée chez les malades avec douleur antérieure du genou.
