Graft utilized in the primary reconstruction, time from initial reconstruction to re-injury, activity at re-injury, time to revision reconstruction, and location of ACL graft tear were recorded.Median patient age at primary ACL reconstruction was 18.5£¿years (range, 13¨C39£¿years). The primary reconstructions included 20 autografts (13 hamstrings, 6 patellar tendons, 1 iliotibial band), 12 allografts (5 patellar tendon, 5 tibialis anterior tendons, 2 achilles tendons), and 2 unknown. The median time from primary reconstruction to re-injury was 1.2£¿years (range, 0.4 ¨C 17.6£¿years). The median time from re-injury to revision reconstruction was 10.4£¿weeks (range, 1 to 241£¿weeks). Failure location could be determined in 30 patients. In the autograft group 14 of 19 grafts failed near their femoral attachment, while in the allograft group 2 of 11 grafts failed near their femoral attachment (p£¿<£¿0.02).When ACL autografts fail traumatically, they frequently fail near their femoral origin, while allograft reconstructions that fail are more likely to fail in other locations or stretch.Level III - Retrospective cohort study %K Anterior cruciate ligament %K Failure %K Location %K Autograft %K Allograft %U http://www.smarttjournal.com/content/4/1/22/abstract
