摘要: 采用两种不同方式测试了1组正常年轻男性膝关节前交叉韧带及髌腱的力学特性。结果表明,正常前交叉韧带(ACL)具有不小于2000N的极限拉伸强度,宽度为10mm的中1/3髌腱强度显着高于正常ACL,测试时试件与力线的相对取向影响测试的结果。提出在解剖取向下得出的结果更能反映ACL实际具有的强度。

Abstract: Two different methods were used to examine the biomechanical properties of the anterior cruciate ligament and the central one third patellar tendon. The patients'mean age was 26.The speimens were divided into two groups of four pairs each at random. The results showed that ACLpossessed the strength above 2000 N, the 10 mm wide central one third patellar tendon had the strength that was significantly higher than that of ACL. The relative orientation of the specimens to the line of tensile load affected the results. The authors believe that the results gained under anatomical orientation are more close to the real characteristics of the ACL.

Key words: knee joint ligament, patellar tendon, strength
