The purpose of this study was to evaluate the outcomes for patients younger than 25 years who had anterior cruciate ligament (ACL) reconstructions with allograft tissue.


A total of 52 ACL reconstructions performed with fresh-frozen, nonirradiated tibialis or Achilles allografts in active patients younger than 25 years. Outcome evaluations included the International Knee Documentation Committee (IKDC) objective and subjective forms, KT-1000 arthrometry and Lysholm.


Forty-two patients were available for follow-up at an average follow-up of 65 months (range, 33-99 months). The average age at surgery was 17 years and 7 months (range, 11 years 10 months-24 years 8 months). Objective and subjective data were obtained from 37 patients with 1 requiring revision, and 5 patients had only subjective data. IKDC objective results were 29-A and 5-B. KT-1000 differences were 0 mm for 4 patients, 1 mm for 23, 2 mm for 8, 3 mm for 1, and > 5 mm for 1 patient. The average IKDC subjective score was 90.2 ± 15.0 and average Lysholm score was 90.0 ± 11.


The result of our study found that using nonirradiated Achilles or tibialis tendon allografts for ACL reconstructions in active patients younger than 25 years can achieve good outcomes, with a low rate of failure.
