聚对苯二甲酸乙二醇酯LARS韧带是术后修复后交叉韧带所用的LARS韧带残留物。本实验旨在研究兔前交叉韧带重建后聚对苯二甲酸乙二醇酯LARS韧带的组织学特点和超微结构。为此，我们对9只兔(L-LARS组)用覆盖有前交叉韧带残余物的聚对苯二甲酸乙二醇酯LARS韧带替换了原有的前交叉韧带，而对3只兔(LARS组)仅用覆盖有前交叉韧带残余物的聚对苯二甲酸乙二酯LARS韧带进行了移植。与LARS组相比，L-LARS组炎症细胞反应和异物反应更明显。此外，电子显微镜观察显示，L-LARS组LARS纤维附近的组织高度细胞化，基质由细小的胶原纤维(50-100 nm)组成。以上结果提示，聚对苯二甲酸乙二醇酯LARS韧带具有较高的生物相容性，有助于聚对苯二甲酸乙二醇酯LARS表面覆盖受体结缔组织。
Polyethylene terephthalate LARS ligament were the remnant of LARS ligament used for repairing posterior cruciate ligament obtained from operation. We want to study histological characteristics and ultrastructure of polyethylene terephthalate LARS ligament after the reconstruction of anterior cruciate ligament in rabbits. Therefore, we replaced the original ACL with polyethylene terephthalate LARS ligament which was covering with the remnant of ACL in 9 rabbits (L-LARS group), while just only polyethylene terephthalate LARS ligament were transplanted in 3 rabbits (LARS group) with the remnant of ACL. Compared with group LARS, inflammatory cell reaction and foreign body reaction were more significant in group L-LARS. Moreover, electron microscopy investigation showed the tissue near LARS fibers was highly cellular with a matrix of thin collagen fibrils (50-100 nm) in group L-LARS. These above findings suggest the polyethylene terephthalate LARS ligament possess the high biocompatibility, which contributes to the polyethylene terephthalate LARS covered with recipient connective tissues.
