Previously the biomechanical properties of the bioabsorbable poly-L: /D: -lactide (PLDLA) 96/4 suture were found suitable for flexor tendon repair. In this study, three PLDLA suture strands were bound together parallel to each other side-by-side to form a triple-stranded bound suture and the modified Kessler tendon repair was performed. The biomechanical properties of the PLDLA repair in porcine extensor tendons ex vivo were investigated with static and cyclic tensile testing. In both biomechanical tests, the strength of the PLDLA repair achieved the estimated forces needed to withstand active mobilization.
先前发现可生物吸收的聚-L:/D:-丙交酯(PLDLA)96/4缝线的生物力学特性适用于屈肌腱修复。在本研究中,将三根PLDLA缝线彼此平行并排绑在一起,形成三股捆绑缝线,并进行改良的凯斯勒肌腱修复。通过静态和循环拉伸试验研究了PLDLA修复猪伸肌腱的生物力学特性。在这两种生物力学测试中,PLDLA修复的强度均达到了承受主动活动所需的估计力。
