摘要

目的：探讨膝关节半月板损伤MRI分级与半月板突出的相关性。方法：回顾性分析420例有膝关节症状病人的膝关节MRI表现，进行半月板损伤MRI分级评价及半月板突出大小的测量，统计分析膝关节半月板损伤MRI分级与半月板半脱位之间的相关性。结果：420例病人，包括内外侧共840个半月板。MRI分级0级128个，其中半脱位4个；I级258个，半脱位44个；II级149个，半脱位25个；III级305个，半脱位81个。半月板MRI分级和是否发生半月板半脱位之间存在相关性（χ2＝34.074，P<0.01），I～III级的发生率高于0级，I、II级之间差别不大，III级高于I、II级。在154例脱位半月板中，内侧半月板98个，外侧半月板56个，两者之间的差别有显著统计学意义（χ2=14.026，P＜0.01）。结论：膝关节半月板MRI分级与半月板半脱位密切相关。

Abstract

Objective: To explore the correlation between the grade of meniscal laceration and meniscal subluxation on MRI. Methods: MRI of 420 cases with symptoms in the knees were evaluated retrospectively, classifying the degree of the injury and measuring the width of meniscal protrusion, and analyzing statistically the correlation between the grade of meniscal injury and meniscal subluxation. Results: Among the 420 cases, including 840 lateral and medial menisci, 128 cases were graded as 0 degree, 4 of them associated with meniscal subluxation; 258 cases were graded as I degree, 44 of them associated with meniscal subluxation; 149 cases were graded as II degree, 25 of them with meniscal subluxation; 305 cases were graded as III degree, 81 of them with meniscal subluxation. Between the laceration on MRI and meniscal subluxation existed dependability(χ2＝34.074, P<0.05). I～III degree was higher than 0 degree; there was no obvious difference between I and II degree; III degree was higher than I and II degree. Among the 154 cases of meniscal subluxation, 98 cases were medial meniscus, 56 cases were lateral meniscus, the difference in incidence have statistical significance. Conclusion: There is high dependability between the classification of laceration on MRI and meniscal subluxation.
