Abstract

Twenty Rottweier dogs were included to investigate the biomechanical behaviors of bone-patellar tendon-bone and bone-ACL-bone grafts for ACL reconstruction. Those dogs were further divided into three experimental groups and one control group. The group I was sacrificed three months after ACL reconstruction, the group II, six months and the group III, twelve months. For bone-patellar tendon-bone graft, the mean maximum tensile strength was 117.1 N in the group I, 232.8 N in the group II and 777.4 N in the group III. For bone-ACL-bone autograft, the mean maximum tensile strength was 458.7 N in the group I, 814.4 N in the group II and 1064.1 N in the group III. The mean maximum tensile strength was 1461.7 N in the control group. This study revealed the bone-ACL-bone graft has a better result than bone-patellar tendon-bone graft for ACL reconstruction in the dog model.
