目的评价超声在膝关节骨关节炎患者中股骨髁关节面软骨损伤的诊断价值。方法根据国际软骨修复协会软骨损伤的分级标准,对20例膝关节骨关节炎患者膝关节置换术截骨残片的关节面软骨进行了大体肉眼观察和超声检查的对比研究。结果88个含有关节面软骨的股骨远端截骨残片大体肉眼观察发现0、Ⅰ、Ⅱ、Ⅲ、Ⅳ级软骨损伤0、7、31、36、14个,而超声检查显示0、Ⅰ、Ⅱ、Ⅲ、Ⅳ级软骨损伤2、5、26、43、12个。对比统计分析显示结果显著相关(相关系数0.963,P<0.05)。结论超声能准确显示股骨髁远端关节面各级软骨损伤,对于Ⅱ、Ⅲ级软骨损伤超声诊断较肉眼观察更准确、可靠。
Objective To evaluate the diagnostic value of ultrasound in the articular cartilage injury of femoral condyle in patients with knee osteoarthritis. Methods According to the cartilage injury grading standards of the International Society of Cartilage Repair, the macroscopic and ultrasonographic examination of articular cartilage in 20 patients with knee osteoarthritis knee osteoarthritis was performed. Results Eighty-eight cartilage lesions of 0, I, II, III, and IV grade cartilage were necrotic in 0, 1, 3, 3, and 14 cartilage lesions in 88 articular cartilages with distal osteotomy fragments. Ultrasound examination revealed 0, , Ⅲ, Ⅳ grade cartilage injury 2,5,26,43,12. Comparative statistical analysis showed that the results were significantly correlated (correlation coefficient 0.963, P <0.05). Conclusion Ultrasound can accurately display the cartilage injury at all levels of the distal femoral condyle. It is more accurate and reliable to diagnose the cartilage damage of grade Ⅱ and Ⅲ than the naked eye.
