摘要
目的:通过分析伴有内侧半月板半脱位的膝关节MRI影像学改变,探讨内侧半月板半脱位与膝关节损伤的关系。方法:回顾性分析77例内侧半月板半脱位的膝关节MRI表现。结果:①韧带损伤:26例前交叉韧带断裂(4例完全断裂、22例部分断裂),与关节镜诊断完全符合率为88.8%;26例后交叉韧带断裂(3例完全断裂、23例部分断裂),与关节镜诊断完全符合率为95%;17例内侧副韧带损伤(1例Ⅲ级损伤、13例Ⅱ级损伤、3例Ⅰ级损伤);13例外侧副韧带损伤(8例Ⅱ级损伤,5例Ⅰ级损伤);与关节镜诊断完全符合率为90%。②半月板损伤:73例内侧半月板损伤(50例Ⅲ度损伤、13例Ⅱ度损伤、10例Ⅰ度损伤);30例外侧半月板损伤(10例Ⅲ度损伤、8例Ⅱ度损伤、12例Ⅰ度损伤);MRI对半月板诊断结果与关节镜诊断完全符合率为90.5%;46例内侧半月板后根部损伤,与关节镜诊断完全符合率为92.21%。③软骨损伤:68例软骨损伤(1例4级损伤,21例3级损伤,46例2级损伤);与关节镜诊断完全符合率为73%。④骨质增生:40例骨赘形成。结论:半月板半脱位是膝关节韧带损伤、半月板损伤、软骨损伤及骨质增生的重要间接征象。重视MRI内侧半月板半脱位,对于上述膝关节损伤的检出具有重要意义,能够有效防止膝关节骨性关节病的发生与发展。
Objective： To evaluate the relationship between medial meniscus subluxation and knee injury by MRI. Methods： Knee MRI of 77 patients with medial meniscus subluxation was analyzed retrospectively. Results： ①Ligament injury： 26 cases had anterior cruciate ligament rupture （4 complete rupture and 22 partial rupture）, with a consistency of 88.8% with the arthroscopic diagnosis; 26 cases had posterior cruciate ligament rupture （3 complete rupture and 23 partial rupture）, with a consistency of 95.0% with the arthroscopie diagnosis; 17 cases had medial collateral ligament injury （1 grade III, 13 grade II and 3 grade I injury）; 13 cases had lateral collateral ligament injury （8 grade II and 5 grade I injury）, with a consistency of 90.0% with the artbroscopie diagnosis. ②Meniscns injury： 73 cases had medial meniscus injury（50 degree III, 13 degree II and 10 degree I injury）; 30 cases had lateral meniscus injury （10 degree m, 8 degree II and 12 I degree injury）, with a consistency of 90.5% with the arthroscopie diagnosis; 46 cases had posterior root injury of the medial meniscus, with a consistency of 92.21% with the arthroseopic diagnosis. ③Cartilage damage： 68 cases had cartilage damage（1 grade 4, 21 grade 3, 46 grade 2 damage）, with a consistency of 73% with the arthroscopic diagnosis. ④Bone hyperplasia： 40 cases had osteophyte formation. Conclusion： Medial meniscus suhluxation is an important indirect sign of ligament injury, meniscus injury, cartilage injury and osteoarthritis. MRI diagnosis of medial meniscus snbluxation is significant for the detection of knee injuries, and can effectively prevent knee osteoarthritis initiation and progress.
