摘要
目的 探讨二维超声、能量多普勒和彩色多普勒对膝关节骨性关节炎诊断的临床价值。对象和方法 :83例 (118个膝关节 )膝关节骨性关节炎患者和 61例 (61个膝关节 )对照组均接受了临床、实验室、X线、超声的检查。结果 ⑴超声显示出对照组和病例组的滑膜厚度和软骨厚度存在显著差异 (P <0 0 1) ;⑵超声显示出对照组中膝关节软骨厚度随年龄的增长而逐渐变薄 ,这一变化趋势在 60岁以后尤为明显 ;⑶高频超声检测出关节软骨轻度病变 9个膝关节 (7 63 % )、中度病变 5 6个膝关节 (4 7 46% )、重度病变 5 3个膝关节 (4 4 92 % ) ,而X线无直接征象。结论 高频超声因对关节软骨的清晰度、软骨表面轮廓的光滑度以及软骨厚度和软骨的完整性分辨力较高 ,可以显示膝关节骨性关节炎软骨表面粗糙、磨损、软骨变薄、软骨厚度改变、软骨透声变化等一系列病理改变 ,因此认为 ,高频超声可以作为辅助诊断关节软骨病变的检查工具。
Objective To evaluate the role of two-dimensional ultrasound, conventional color and power Doppler ultrasound in the diagnosis of knee osteoarthritis. Methods Eighty-three patients with knee osteoarthritis (118 knee joints) and 61 healthy subjects as a control received clinical, laboratory and ultrasound examinations. Results A higly significant difference in the thickness of knee articular cartilage between the patients and controls was found by ultrasound examination(P<0.01). The attenuating tendency of knee joint cartilage thinkness with age was displayed by ultrasound examination in healthy subjects, especially in more than 60 years old people. Nine(7.63%) cases of mind, 56(47.46%) cases of moderate and 53(44.92%) cases of severe lesions of knee articular cartilage were observed by real-time high-frequency ultrasound. Conclusion High-frequency ultrasound could find a series of pathological changes of articular cartilages in knee osteoarthritis, such as coarseness, abrasion and attenuation of the articular cartilage, and may be a supplementary tool for detecting the pathological lesions of articular cartilage.
