Long-term results of anterior cruciate ligament reconstruction using semitendinosus and gracilis tendons with Kennedy ligament augmentation device compared with patellar tendon autografts

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 < or = 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.
