In a prospective clinical study of 54 patients with acute anterior cruciate ligament instability, 56 artificial ligaments made of polyethylene terephthalate (Trevira hochfest) were implanted to restore knee stability. The average follow-up of these artificial knee ligaments was 40.2 (12-79) months; five implants (10%) had to be explanted due to failure after an average of 17.8 (6-50) months. All explants were examined by histological and ultrastructural methods in a device retrieval analysis. With regard to short- and medium-term artificial ligament failure in the human knee joint, a non-isometric surgical implantation technique, inappropriate strain during rehabilitation and implant fatigue and wear were responsible for ligament failures.
在一项针对54例急性前交叉韧带不稳定患者的前瞻性临床研究中，植入了56条由聚对苯二甲酸乙二酯（特瑞维拉高强度）制成的人工韧带以恢复膝关节稳定性。这些人工膝关节韧带的平均随访时间为40.2（12 - 79）个月；5例植入物（10%）因失败在平均17.8（6 - 50）个月后不得不取出。在器械取出分析中，所有取出物均通过组织学和超微结构方法进行检查。关于人体膝关节人工韧带的短期和中期失败，非等距手术植入技术、康复期间不适当的应变以及植入物疲劳和磨损是韧带失败的原因。
