Abstract

Nanomaterials are solid systems composed of 1–100 nm particles. These systems usually include nanomaterial sensors, nanomolecules, imaging technology, drug transportation, and DNA delivery. Therefore, nanomaterials are widely used in biomedicine, biochemical analysis, mechanics, and magnetism. Based on the above background, this paper mainly studies the application of nanomaterials in the repair of basketball sports ligament injury. In this paper, the nanomaterials used in medical treatment were analyzed, and the polyacrylonitrile based carbon fiber was selected to replace the anterior cruciate ligament (ACL). In this paper, based on polyacrylonitrile based carbon fiber for ACL replacement surgery in rabbits, the drawer test, IKDC score, and Lysholm score were compared between the rabbits after operation and those in the control group. The experiment proved that the function of the left knee joint was gradually restored after the ACL was excised and replaced by polyacrylonitrile based carbon fiber. After 8 weeks, the function of the left knee joint recovered 90%, which proved the feasibility of polyacrylonitrile based carbon fiber in the repair of anterior cruciate ligament injury.

摘要

纳米材料是由 1-100 nm 颗粒组成的固体系统。这些系统通常包括纳米材料传感器、纳米分子、成像技术、药物运输和 DNA 输送。因此，纳米材料在生物医学、生化分析、力学、磁学等方面有着广泛的应用。基于以上背景，本文主要研究纳米材料在篮球运动韧带损伤修复中的应用。本文对用于医疗的纳米材料进行了分析，选择聚丙烯腈基碳纤维代替前交叉韧带（ACL）。本文基于聚丙烯腈基碳纤维用于兔前交叉韧带置换手术，比较了手术后兔与对照组兔的抽屉试验、IKDC评分和Lysholm评分。实验证明左膝关节功能在前交叉韧带切除后用聚丙烯腈基碳纤维替代后逐渐恢复。8周后，左膝关节功能恢复90%，证明聚丙烯腈基碳纤维修复前交叉韧带损伤的可行性。
