目的：评估胫股关节（TFJ）中放射学诊断的骨赘与（1）磁共振（MR）检测到的同一关节中的软骨缺损和软骨病变以及（2）膝关节疼痛之间的相关性。方法：59例慢性膝关节疼痛患者，男性29例，女性30例。年龄41-58岁，平均50岁。评估边缘和中央骨赘的存在和分级。同一天，在1.0 T成像仪上使用质子密度和T2加权快速自旋回波序列对信号膝关节进行MR检查。观察到TFJ中的软骨缺损和软骨异常。受试者被问到目前的膝关节疼痛为each knee. Results-Margin骨赘有一个敏感性为77%，特异性为83%，和阳性预测值为87%的MR检测软骨缺损的TFJ和一个敏感性为71%，特异性为68%，和阳性预测值为71%的骨骼异常。相关性（p
Objective-To assess the correlation between the presence of radiographically diagnosed osteophytes in the tibiofemoral joint (TFJ) and (1) magnetic resonance (MR) detected cartilage defects and meniscal lesions in the same joint and (2) knee pain.Methods-Fifty nine people, 29 men and 30 women, with chronic knee pain (aged 41-58 years, mean 50 years) were examined with posteroanterior weightbearing radiograms in semiflexion of both TFJ. The presence and grade of marginal and central osteophytes were assessed. On the same day, an MR examination was performed of the signal knee with proton density and T2 weighted turbo spin-echo sequences on a 1.0 T imager. Cartilage defects and meniscal abnormalities in the TFJ were noted. The subjects were questioned for current knee pain for each knee.Results-Marginal osteophytes had a sensitivity of 77%, specificity of 83%, and positive predictive value of 87% for MR detected cartilage defects in the TFJ and a sensitivity of 71%, specificity of 68%, and positive predictive value of 71% for meniscal abnormalities.
