前交叉韧带及其替代物粘弹性性质的实验研究

本研究采用新鲜成人膝关节标本，对前交叉韧带及其转换替代物（髌韧带、髂胫束）进行系统的粘弹性力学性质的实验研究，通过粘弹性力学模型的建立，推导前交叉韧带及髌韧带、髂胫束的本构方程，对韧带的蠕变和松驰现象进行系统的分析。结果表明，韧带的损伤与韧带的生理力学性质有关，髌韧带的粘弹性性质更接近前交叉韧带，关节内髌韧带转换比髂胫束为佳。

EXPERIMENTAL STUDY ON VISCOELASTICITY PROPERTY OF THE ANTERIOR CRUCIATE LIGAMENT AND ITS REPLACEMENT

Using tresh cadaveric knee jiont specimens, the author makes systematic experimental researcheson the ligament viscoelasticity property of the anterior cruciate ligament and its replacements thepatellar ligament and the illiotibial tract. The author establishes the viscoelasticity mechanicalmodel,deduces the constitute equation of the anterior cruciate ligament, the patellar ligament andilliotibial tract, makes systematic analyses of the creep and loose phenomenon of the ligament. Theresults indicate that ligament failure is connected with its biomechanical properties, theviscoelasticity property of patellar ligament is more like that of the anterior cruciate ligament, theintra-articular substitution using the patellar ligament is better than using illiotibial tract.
