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.
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.
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. A correlation (p < 0.05) between osteophytes at the medial tibial condyle and knee pain was found.
With the presence of marginal osteophytes in the TFJ there is a high prevalence of MR detected cartilage defects in the same joint whether joint space narrowing (< 3 mm) is present or not.
评估经X线片诊断的胫股关节（TFJ）骨赘与（1）磁共振（MR）检测到的同一关节软骨缺损和半月板损伤以及（2）膝关节疼痛之间的相关性。
对59例慢性膝关节疼痛患者（29例男性，30例女性，年龄41 - 58岁，平均50岁）进行双侧TFJ半屈曲位负重前后位X线片检查，评估边缘性和中央性骨赘的存在情况及分级。同一天，在1.0T成像仪上采用质子密度加权和T2加权快速自旋回波序列对患侧膝关节进行MR检查，记录TFJ的软骨缺损和半月板异常情况。询问受试者每个膝关节当前的疼痛情况。
边缘性骨赘对MR检测到的TFJ软骨缺损的敏感度为77%，特异度为83%，阳性预测值为87%；对半月板异常的敏感度为71%，特异度为68%，阳性预测值为71%。发现胫骨内侧髁骨赘与膝关节疼痛之间存在相关性（p < 0.05）。
无论是否存在关节间隙狭窄（< 3mm），TFJ边缘性骨赘的存在与MR检测到的同一关节软骨缺损的高患病率相关。
