Biomechanical Study of Bone-Patellar Tendon-Bone and Bone-ACL-Bone Grafts
骨－髕骨韌帶－骨與骨－前十字韌帶－骨移植之生物力學研究
摘要
本研究探討骨－髕骨韌帶－骨與骨－前十字韌帶－骨作為前十字韌帶重建的移植材料的生物力學特性，研究方法以20隻Rottweier狗為實驗對象，其中18隻為實驗組，2隻為控制組，實驗組又區分為第一組：重建後三個月；第二組：六個月；第三組：十二個月犧牲做拉伸實驗以比較這兩種移植材料的最大抗拉強度。在骨－髕骨韌帶－骨組最大的抗拉強度三個月為117.1牛頓、六個月為232.8牛頓、十二個月為777.4牛頓；在骨－前十字韌帶－骨組最大的抗拉強度三個月為458.7牛頓、六個月為814.8牛頓、十二個月為1064.1牛頓；而控制組前十字韌帶最大抗拉強度為1461.7牛頓。本研究證實骨－前十字韌帶－骨作為前十字韌帶的重建材料比骨－髕骨韌帶－骨在生物力學的特性上較佳。

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.
