摘要
目的探讨膝骨关节炎磁共振出现软骨下骨髓水肿样病变(BMLs)的危险因素。方法 41例膝骨关节炎患者纳入研究,采用WORMS法评估膝关节磁共振软骨下BMLs,采用Logistic回归分析BMLs的危险因素。结果体重指数、年龄是膝关节软骨下BMLs的危险因素,体重指数(r=0.437,P=0.004)、年龄(r=0.358,P=0.022)分别与BMLs呈正相关。结论体重指数、年龄是膝骨关节炎软骨下BMLs的危险因素,体重指数、年龄越大,软骨下BMLs也越严重。
Objective To clarify the risk factors for subchondral bone marrow edema- like lesions （BMLs） on magnetic resonance imaging （MRI） in knee osteoarthritis （OA）. Methods Forty one patients with knee OA were included in the study. BMLs on MRI was evaluated according to the WORMS system. Risk factors for BMLs were tested by univariate and multivariate logistic regression analyses. Results Risk factors for BMLs were body mass index （BMI） and age. BMI （r=0.437, P=0.004） and age （r=0.358, P=0.022） respectively showed a positive correlation with BMLs. Conclusion Risk factors for BMLs in knee OA were BMI and age. Higher BMI and older age are associated with more serious BMLs.
