目的 评价高频超声对创伤性膝关节滑膜炎诊断及观察疗效的价值。方法 回顾性分析42例创伤性膝关节滑膜炎患者的临床资料,分析其高频超声(超声组)声像图表现,并将患者滑膜厚度、关节积液测量值与X线平片(X线组)及磁共振(MRI组)做比较。结果 创伤性滑膜炎急性期滑膜厚度、关节腔积液的数值,超声组为(4.1±1.4)mm、(15.8±3.7)mm,X线组为(1.9±0.5)mm、(9.4±2.0)mm,MRI组为(4.2±1.2)mm、(16.2±4.1)mm。超声组与X线组比较均有统计学差异(P＜0.05),与MRI组比较均无统计学差异。治疗前后滑膜厚度、关节腔积液及滑膜内血流信号高频超声测值比较有统计学差异(P＜0.05)。结论 高频超声在诊断创伤性膝关节滑膜炎、判断病情和随访中有较高的应用价值。

Objective To study the diagnosis value of high-frequency ultrasonography in the gonarthromenigitis caused by army training. Methods A total of 42 patients with gonarthromenigitis caused by army training were collected to retrospective analysis. The ultrasonographic characteristics of gonarthromenigitis were analyzed and compared with those of X-rays and knee magnetic resonance imaging (MRI). Results In ultrasound group, X-rays group, MRI group of acute traumatic synovitis, the synovial membrane thickness, articular cavity effusion quantity were (4.1?1.4) mm,(15.8?3.7) mm;(1.9?0.5) mm,(9.4?2.0) mm;(4.2?1.2) mm,(16.2?4.1) mm, respectively. The difference of detection rates between ultrasound group and X-rays group was significant(P<0.05), yet the difference between ultrasound group and MRI group was not significant. Before and after treatment those of high frequency ultrasound in synovial measurements were statistically significant(P<0.05). Conclusions High frequency ultrasound in the diagnosis of traumatic synovitis, judging condition and follow-up has high application value.
