膝骨关节炎周围骨髓水肿与股四头肌面积、半月板分级的相关性分析

Correlation Analysis of Bone Marrow Edema Around Knee Osteoarthritis with Quadriceps Area and Meniscus Grade

目的探讨膝骨关节炎(KOA)周围骨髓水肿与股四头肌面积、半月板分级的相关性。方法我院2019年7月至2020年6月诊治的40例KOA患者,采用CT检查计算患者的股四头肌面积,采用磁共振检查进行骨髓水肿分级、半月板分级。采用Pearson法分析KOA患者骨髓水肿与股四头肌面积、半月板分级的相关性。结果与轻度组相比,中、重度组股四头肌面积较小,中度组显著小于重度组,差异具有统计学意义(P<0.05);与轻度组相比,中、重度组半月板分级越高,中度组显著高于重度组,差异具有统计学意义(P<0.05)。骨髓水肿与股四头肌面积呈负相关,差异具有统计学意义(P<0.05),与半月板分级呈正相关,差异具有统计学意义(P<0.05)。结论KOA骨髓水肿与股四头肌面积、半月板分级具有显著相关性。

Objective To explore the correlation between bone marrow edema around knee Osteoarthritis(KOA)and quadriceps area and meniscus grade.Methods From July 2019 to June 2020,40 patients with KOA were diagnosed and treated in our hospital.The area of quadriceps femoris was calculated by CT,and bone marrow edema and meniscus were graded by MRI.Pearson method was used to analyze the correlation between bone marrow edema and quadriceps area and meniscus grade in OA patients.Results Compared with mild group,the quadriceps area in moderate and severe group was smaller,and the difference was statistically significant(P<0.05).Compared with mild group,the meniscus the grade of moderate and the severe group was higher,and the difference was statistically significant(P<0.05).Bone marrow edema was negatively correlated with quadriceps femoris area(P<0.05)and positively correlated with meniscus grade(P<0.05).Conclusion KOA bone marrow edema was significantly correlated with quadriceps area and meniscus grade.
