目的：探讨磁共振成像(MRI)与关节镜测量膝关节软骨缺损面积的一致性。方法选取36例(36膝)因膝关节软骨缺损的入院患者，对照分析其关节镜及术前 MRI 资料。比较 MRI 与关节镜术中测量软骨缺损区面积的一致性。结果MRI 与关节镜均发现膝关节软骨缺损92处，平均每例2.6处。经 MRI 测量，平均每膝的软骨缺损面积为(1.9±1.5)cm2；经关节镜测量，平均每膝的软骨缺损面积为(2.9±2.6)cm2；MRI 与关节镜测量结果之间差异有统计学意义(P <0.001)。MRI 的评估结果低于关节镜测量结果，平均差值为(1.7±1.1)cm2。MRI 测量的面积为关节镜测量结果的70.1%。结论MRI 诊断关节软骨缺损病灶数目上与关节镜具有良好的一致性；可直接或间接反映膝关节软骨缺损面积，定位、定性诊断较为准确。

Objective To explore the consistency of knee articular cartilage defect area by magnetic resonance imaging (MRI)and arthroscopy.Methods Thirty-six patients (36 knees)with knee cartilage lesions were collected in our study.The defect area meas-urement of knee articular cartilage by MRI and arthroscopy was compared.Results A total of 92 lesions were detected by both MRI and arthroscopy with an average of 2.6 defects per knee.Preoperative MRI resultes demonstrated the mean defect area per knee was (1.9±1.5)cm2 ,while arthroscopic measurement after debridement indicated the mean defect area per knee was (2.9±2.6)cm2 , which had significant difference(P <0.001).The area measured by MRI was less than that by arthroscopy,and the mean difference was (1.7 ± 1.1)cm2 .The mean area measured by MRI was 70.1% of that by arthroscopy.Conclusion Arthroscopy and MR have good consistency in the number of articular cartilage defect lesions .MRI can reflect the knee articular cartilage defect area directly or indirectly,and be capable of accurate positioning and qualitative diagnosis.
