［摘 要］ 目的：回顾前交叉韧带重建术后正常移植物不同时期的信号特点及并发症的磁共振成像（magnetic resonance imag⁃
ing，MRI）表现。方法：回顾分析2012年1月—2023年3月在南京医科大学第一附属医院因前交叉韧带重建复查而行MRI 检查
的299例患者的影像学资料，根据移植物并发症在MRI 上的不同表现进行分类，描述其在T1WI和T2WI上的信号表现，并与其
临床症状相结合。结果：在299例患者中，手术后4~6个月T2WI上移植物信号最高。66例（22.07%）出现了移植后并发症，包
括5例（1.67%）胫骨隧道前移，1例（0.33%）胫骨隧道位置稍偏后。16例（5.35%）出现Cyclops病变，10例（3.34%）发生移植物的
再次断裂，1例（0.33%）出现术后感染。33 例（11.04%）在术后不同时间出现移植物隧道内囊性灶。在胫骨隧道前移的患者
中有 2 例同时出现了移植物的再次断裂和 Cyclops 病变。结论：MRI 作为前交叉韧带重建患者术后复查的一种主要方式，发
挥重要作用，它能清晰反映移植物在不同阶段的变化及并发症表现，有早发现早提示的作用，以便临床医生早期采取干预
措施，提高患者术后的生活质量。

［Abstract］ Objective：This study aims to review the magnetic resonance imaging（MRI）features of normal grafts at different stages
of signal characteristics and complications after anterior cruciate ligament reconstruction（ACLR）. Methods：The imaging data of 299
patients who underwent MRI for reexamination after the ACLR at the First Affiliated Hospital of Nanjing Medical University from
January 2012 to March 2023 were reviewed，and were classified according to the different manifestations of graft complications on MRI.
Their signal on T1WI and T2WI was described and combined with their clinical symptoms. Results：In 299 patients，signal was highest
at 4-6 months postoperatively. Post⁃transplantation complications were observed in 66（22.07%），of which 5（1.67%）had an anterior
displacement of the tibial tunnel ，and 1（0.33%）had a slightly posterior position of the tibial tunnel. Cyclops lesion was seen
in 16（5.35%），re⁃rupture of the graft occurred in 10（3.34%），and 1（0.33%）had a postoperative infection. Cystic signal in the tunnel
were present in 33（11.04%）at various times postoperatively. There are 2 patients who underlying anterior displacement of the tibial
tunnel had both re⁃rupture and Cyclops lesion of the graft. Conclusion：MRI plays an important role as a major tool for postoperative
follow ⁃ up of patients after ACLR. It can clearly reflect the changes of the graft at different stages and the manifestation of
complications，providing early detection and warning，so that clinicians can take early interventions to improve the quality of life for
patients after surgery.
