目的：评估髌股关节（PFJ）轴位和侧位X线诊断骨赘与（1）磁共振（MR）检测同一关节软骨缺损和（2）膝关节疼痛之间的相关性。年龄41-58岁，平均50岁。评估骨赘的存在和分级。同一天，在1.0 T成像仪上，采用质子密度和T2加权快速自旋回波序列在矢状面和轴位对信号膝关节进行MR检查。观察到PFJ中的软骨缺损。受试者被问到目前的膝关节疼痛为每个knee.Results-Osteophytes在PFJ有一个特异性变化之间的59和100%和MR检测软骨缺损的阳性预测值之间的74和100%。股骨转子外侧骨赘的相应值均为100%。在PFJ中，狭窄（
Objective-To assess the correlation between radiographically diagnosed osteophytes in the axial and lateral view of the patellofemoral joint (PFJ) and (1) magnetic resonance (MR) detected cartilage defects in the same joint and (2) knee pain.Methods-Fifty seven pepole with chronic knee pain, (aged 41-58 years, mean 50 years) were examined with axial and lateral radiograms when standing of the right and the left PFJ. The presence and grade of osteophytes was assessed. On the same day, a MR examination was performed of the signal knee with proton density and T2 weighted turbo spin-echo sequences in the sagittal and axial view on a 1.0 T imager. Cartilage defects in the PFJ were noted. The subjects were questioned for current knee pain for each knee.Results-Osteophytes at the PFJ had a specificity varying between 59 and 100% and a positive predictive value between 74 and 100% for MR detected cartilage defects. The corresponding values for osteophytes at the lateral aspect of the femoral trochlea were both 100%. In PFJ with narrowing (
