摘要

背景:尽管前交叉韧带(ACL)修复手术技术有所进步,但仍有相当一部分患者在术后出现持续的膝盖疼痛/不稳定。目的:评估磁共振成像(MRI)上股骨/胫骨隧道的位置,并将其与ACL移植物完整性/移植物相关并发症的相关性。研究设计/设置:这是一项在阿曼马斯喀特Burjeel医疗中心进行的横断面研究。材料和方法:研究期间为2015年11月至2017年6月,使用飞利浦Ingenia 1.5特斯拉MRI机器。本研究共招募了30名男性患者,年龄从20岁到43岁不等,他们在ACL重建后1年出现膝盖疼痛/不稳定。结果:在30例患者中,10例(33.33%)患者在MRI上有完整的移植物。在其余20例患者中,15例(50%)患者出现移植物撞击,3例(10%)患者出现移植植物撕裂,其余2例(6.67%)患者出现具有异常高T2信号的移植物拉伸。在本研究中未处理的少数患者中,出现了膝关节前间隙局灶性关节纤维化和胫骨隧道囊肿的相关表现。在20例移植物异常患者中,3例(15%)股骨隧道异常,16例(80%)胫骨隧道部分或完全位于Blumensaat延长线的MRI等效线之前,1例(5%)两个隧道均正常。结论:股骨/胫骨隧道的位置是ACL重建患者术后移植物完整性的最重要决定因素。

Location of femoral/tibial tunnels in anterior cruciate ligament reconstruction and their impact on graft integrity: Magnetic resonance imaging review
Context: Despite advances in surgical techniques for anterior cruciate ligament (ACL) repair, a significant proportion of patients encounter persisting pain/instability of the knee postoperatively. Objectives: To assess the location of femoral/tibial tunnels on magnetic resonance imaging (MRI) and to correlate the findings with the ACL graft integrity/graft-related complications. Study Design/Settings: This was a cross-sectional study done at Burjeel Medical Centre, Muscat, Oman. Materials and Methods: The study period was between November 2015 and June 2017 on Philips Ingenia 1.5 Tesla MRI machine. A total of 30 male patients, age ranged from 20 to 43 years who presented with knee pain/instability 1 year postreconstruction of ACL, were recruited for the study. Results: Of 30 cases, 10 (33.33%) patients had an intact graft on MRI. Of the remaining 20 patients, graft impingement was noted in 15 patients (50%), graft tear in 3 cases (10%), and graft stretching with abnormal high T2 signal in the remaining 2 cases (6.67%). Associated findings of focal arthrofibrosis in the anterior knee joint space and tibial tunnel cysts were encountered in few patients who were not dealt with in this study. Out of 20 patients with graft abnormality, femoral tunnel was abnormally located in 3 (15%), tibial tunnel was located anterior to the MRI equivalent of Blumensaat's extension line partly or completely in 16(80%) and both tunnels were normally located in 1(5%). Conclusion: The location of the femoral/tibial tunnels is the most important determinant factor of postoperative graft integrity in ACL reconstruction patients.
