Artificial ligaments such as the Leeds-Keio ligament are inserted into knee joints to treat cruciate ligament trauma. Three cases of prosthetic ligament failure are reported, showing foreign body granulomatous inflammation around implanted fibres, together with abundant fibre particles within giant cells. It is suggested that intra-operative fibre fragmentation can produce a sufficient quantity of dendritic particles to elicit a granulomatous reaction, which can ultimately lead to ligament instability and failure.
诸如利兹-庆应韧带之类的人工韧带被植入膝关节以治疗十字韧带损伤。报告了3例人工韧带失效的病例,显示植入纤维周围有异物肉芽肿性炎症,同时巨细胞内有大量纤维颗粒。提示术中纤维断裂可产生足够数量的树枝状颗粒,引发肉芽肿反应,最终可导致韧带不稳定和失效。
