摘要(Abstract):
[目的]对骨性关节炎软骨钙化层病理结构进行形态学分析,为临床诊治及预防相关疾病提供理论依据。[方法]标本均来源于临床诊断为膝关节退行性骨关节炎患者,共21例,其中,男1例,女20例。股骨髁负重区取材、修剪、固定后,常规制备石蜡切片,番红O/固绿染色,显微镜观察。[结果]本研究收集的标本平均年龄(65.57±7.43)岁;平均身高(155.38±5.32)cm;体均体重(59.95±8.99)kg;平均病程(13.04±9.66)年。番红O固/绿染色示钙化层病理改变主要为潮线复制、漂移,出现多条潮线结构,钙化层结构明显增厚,最厚处为900多微米;钙化层增厚伴血管长入;非钙化软骨及钙化层纤维样改变;潮线间隙增宽;钙化层及深层软骨缺损。[结论]膝关节退行性骨关节炎钙化层形态结构具有特异性的病理改变。
