摘要
目的:研究探讨MRI诊断膝关节侧副韧带损伤的影像学特征、分级情况。方法:收集膝关节侧副韧带损伤的患者24例作为研究对象,采用MRI对其损伤位置进行扫描诊断,观察分析患者的影像学特征,并对患者行关节镜检查,将MRI的诊断结果与关节镜诊断结果进行对照比较,计算MRI诊断的准确率。结果:经MRI检查,24例患者中共检出膝关节侧副韧带损伤29条。分别包括胫侧副韧带损伤和腓侧副韧带损伤以及双侧副韧带同时损伤等三种情况,分别有20条、7条和2条。根据膝关节韧带损伤情况分级可见Ⅰ级膝关节侧副韧带损伤、Ⅱ级膝关节侧副韧带损伤、Ⅲ级膝关节侧副韧带损伤分别有16条、8条和5条。以关节镜检查结果为标准,MRI总的检查准确率为89.7%,3条韧带部分纤维断裂被误诊为完全断裂。患者的并发症检出情况为,14例检出关节积液,4例检出半月板损伤,5例(6条)检出前交叉韧带损伤,4例(6条)检出后交叉韧带损伤,1例患者检出骨折。结论:MRI诊断膝关节侧副韧带损伤的空间分辨率好、准确率高,值得临床推广应用。
Objective:To research and explore the imaging features and the classification of lateral collateral ligament injury of knee joint with the use of MRI.Method:24 patients with injury of lateral collateral ligament of knee joint were chosen as the objective of study.Their injured areas were scanned with the application of MRI.Then, their imaging features were researched and analyzed.The patients were also given arthroscopy.At last, the diagnosis of MRI was compared with that of arthroscopy.At the same time, the accuracy of MRI diagnosis was calculated.Result:Through MRI, 29 pieces of lateral collateral ligament injury of knee joint were detected in the 24 patients., included three conditions,the tibial collateral ligament injuries of 20 pieces,lateral collateral ligament injury of 7 pieces and dual lateral collateral ligament injury of 2 pieces.According to injury of knee lateral collateral ligament injury class,class Ⅰ knee ligament were 16 pieces,class Ⅱ lateral collateral ligament of knee joint injury were 8 pieces,class Ⅲ the ruptured collateral ligament of the knee joint were 5 pieces.With arthroscopy result as the standard, the overall accuracy rate of MRI was 89.7%,3 pieces of ligament fiber breakage misdiagnosed as completely broken.The patients complications were joint effusion of 14 cases,meniscus injury of 4 cases, anterior cruciate ligament injury of 5 cases(6 pieces), after cruciate ligament injury of 4 cases(6 pieces), and fracture of 1 case.Conclusion:With good space resolution and high accuracy during the diagnosis of lateral collateral ligament injury of knee joint, MRI should be spread.
