ABSTRACT

ACL reconstructions were postoperatively evaluated in 102 patients who underwent surgery using an arthroscopically assisted double-incision technique. Augmentation of the distally based semitendinosus and gracilis tendons was done either with the Kennedy ligament augmentation device (LAD) (Group 1 patients, mean follow-up of 108 months) or bone-patellar-tendon-bone graft (Group 2 patients, mean follow-up of 109 months). At follow-up, serial KT-1000 measurements showed ≤ 5 mm side-to-side differences in 70% of Group 1 and 90% of Group 2 patients. No differences were found among patients regarding postreconstruction complications such as loss in motion range, patellofemoral crepitus, osteoarthritis, and muscle disfunction.
