摘要
目的：在膝关节尸体标本上测量前交叉韧带（ACL）止点的形态大小,探讨重建ACL时骨道直径的最佳选择。方法：解剖26具新鲜冷冻的膝关节尸体标本,标记ACL股骨和胫骨止点边界和前内束（AM）和后外束（PL）的分界。确定ACL、AM和PL纵轴并测量其长度,经过纵轴中点作其垂线,沿垂线测量止点宽度,该宽度则为重建骨道的最大直径。结果：测量值用均数（第25百分位数～第75百分位数）表示。ACL、AM和PL胫骨止点纵轴宽度分别为9.06（7.65～9.88）mm,8.47（6.85～9.23）mm和6.43（5.01～7.88）mm;其股骨止点纵轴宽度分别为10.31（8.75～11.50）mm,8.60（7.79～9.23）mm和6.74（5.54～8.00）mm。根据解剖重建和胫骨、股骨骨道相一致的原则,依据镜下测量结果,决定ACL重建时骨道直径。单束重建骨道直径可从7.5 mm到9.5 mm,均值为9 mm。双束重建AM骨道直径可从6.5 mm到9.0 mm,均值为8 mm;PL骨道的直径可从5.0 mm到7.5 mm,均值为6 mm。
Objective To measure the morphology of anterior cruciate ligament（ACL）insertion in human cadaver knee,and to optimize the diameter of tunnel in ACL reconstruction.Methods Twenty six human cadaver knees were dissected,periphery of ACL and boundary of anteromedial（AM）bundle and poteriolateral（PL）bundle in femoral and tibial attachments were marked,and major axis of footprint of ACL,AM and PL were confirmed and its length were measured.The vertical line through the midpoint of the major axis was identified,and thus the width of footprint was measured along this vertical line,which was used as the maximum diameter of tunnel.Results The widthes of ACL,AM,and PL in tibal attachment were 9.06（7.65~9.88）mm,8.47（6.85~9.23）mm and 6.43（5.01~7.88）mm,respectively.In femoral attachment,they were 10.31（8.75~11.50）mm,8.60（7.79~9.23）mm and 6.74（5.54~8.00）mm,respectively.Conclusion According to principle of anatomic ACL reconstruction and consistency of femoral and tibial tunnel,the diameter of tunnel should be determined by intraoperative measurement.The diameter of tunnel range of single-bundle ACL reconstruction was from 7.5 mm to 9.5 mm（averagely 9 mm）,and in double-bundle ACL reconstruction,the diameter of AM tunnel was from 6.5 mm to 9.0 mm（averagely 6mm）.
