解剖位点中心定位重建前交叉韧带膝关节多屈曲角度韧带长度的测量及意义

Measurement of anatomical sites to locate the center of reconstruction of the anterior cruciate ligament of knee flexion angle ligament length and its significance

目的探讨解剖位点中心定位重建前交叉韧带在膝关节多屈曲角度韧带长度及意义。方法 2011年8月-2012年6月对35例前交叉韧带损伤患者施行关节镜下前交叉韧带重建时,分别测量前交叉韧带股骨附丽点中心对胫骨解剖附丽点中心在膝关节0°、30°、90°和120°多屈曲角度时的长度,并了解其与身高的关系。结果解剖中心定位重建前交叉韧带不等长,前交叉韧带屈膝0°时长度与屈30°、90°和120°时差异有显著性,而屈30°、90°和120°时韧带之间长度差异无显著性。前交叉韧带屈膝0°时长度为（26.1±4.8）mm,而屈30°、90°和120°时韧带长度为（23.9±4.5）mm（α=0.05,P〈0.001）。屈膝0°时韧带长度较屈30°、90°和120°时韧带长度长约2.2 mm左右。解剖中心定位重建前交叉韧带与身高有关,直线回归方程为前交叉韧带长（Y）与身高（X）的关糸：Y=-4.1097＋0.039X（α=0.05,P〈0.001）。结论前交叉韧带解剖附丽点中心定位重建膝关节多屈曲角度时韧带不等长,膝关节伸直时韧带较紧张,屈膝后略有放松,各屈曲角度韧带长度无明显差异,韧带长度与身高正相关,在韧带重建定位及固定时需充分考虑。

[Objective] To investigate the anatomic sites to locate the center of reconstruction of the anterior cruciate ligament in knee flexion angle ligament length and its significance. [Methods] From 2011 August to 2012 June 35 eases patients with cruciate ligament injury before arthroscopie reconstruction of the anterior cruciate ligament, ligament femoral attachment point center anatomical attachment dot center in the knee joint of 0°, 30°, 90°, 120° multi flexion angle when the length of the tibia were measured on the cross, and to understand its relationship with height. [ Results ] The anatomic center positioning of anterior cruciate ligament reconstruction with unequal, anterior crueiate ligament knee flexion 0° length and bend 30°, 90°, 120° had significant difference, while flexion 30°, 90°, 120° ligament length no statistical difference between them. Length of anterior erueiate ligament of knee at 0° is （26.1±4.8） mm. With the flexion 30°, 90°, 120° ligament length was （23.9±4.5） mm （=0.05, P 〈0.001）. At 0° length was longer than 30°, 90°, 120° of ligament length was about 2.2 mm. The anatomical location of anterior erueiate ligament reconstruction with height, the linear regression equation for anterior eruciate ligament length （Y） and height （X） of the relationship： Y=-4.1097±0.039X （ct =0.05, P 〈0.001）. [ Conclusion ] Anterior cruciate ligament reattaeh-ment point center positioning reconstruction of knee flexion angle ligaments unequal, ligament is strained knee extension, slightly relaxed down, there is no significant difference between flexion angle ligament length, length and height are related, considering the ligament reconstruction positioning and fixing time.
