摘要
目的探讨膝骨关节炎(OA)患者磁共振成像(MRI)骨髓病变(BML)的发生率及其危险因素。方法 104例膝OA患者,详细记录患者一般情况,测量身高、体重、骨密度等,并行受累膝关节MRI,对各部位(股、胫骨内外侧)分别进行BML评级(0~3级)。分析膝OA患者BML的发生情况及相关影响因素。结果 63例膝OA患者发生BML(BML组),发生率60.6%;41例未发生BML(无BML组);各部位(股、胫骨内外侧)BML的发生率比较差异无统计学意义(P>0.05)。BML组与无BML组之间年龄、病程、体重指数(BMI)比较差异有统计学意义(P<0.05)。单因素Logistic回归分析显示:年龄、病程及BMI与BML相关;进一步多因素Logistic回归分析显示BMI(OR=2.019,95%CI=1.077~3.784)、年龄(OR=1.063,95%CI=1.006~1.122)为发生BML的危险因素。结论膝OA患者MRI中BML的发生率达60.6%,BMI、年龄可视为BML发生的危险因素,且BMI作为可调节的因素,在膝OA的预防和治疗中可能有着重要的意义。
