PURPOSE
To carry out a modern diagnostic survey among patients with a clinical and radiological diagnosis of early osteoarthritis of the knee.
MATERIALS AND METHODS
A magnetic resonance imaging survey was performed on 70 patients (82 knees) with a mean age of 59 years. (range, 40-71 years) who had chronic knee pain, clinical diagnosis of early osteoarthritis of the knee and conventional knee radiographs classified as 1 and 2 on the Kellgren-Lawrence scale.
RESULTS
A variety of different disorders was found; degenerative meniscal lesions with or without ruptures of the anterior cruciate ligament in 70.7% of the knees, osteonecrosis of the femoral and tibial condyles in 9.75%, osteophytes and degenerative articular cartilage lesions in 8.54%, transient osteoporosis in 2.44% and benign neoplasms and cysts in 6.1%.
CONCLUSIONS
The existence of such a heterogenous group of disorders in these "early osteoarthritic knees" may explain failures in treatment and it may justify a modern MRI imaging approach to proper diagnosis.
目的
对临床及影像学诊断为早期膝关节骨关节炎的患者进行一项现代诊断调查。
材料与方法
对70例平均年龄59岁（范围40 - 71岁）的患者（82个膝关节）进行了磁共振成像检查，这些患者有慢性膝关节疼痛，临床诊断为早期膝关节骨关节炎，且传统膝关节X线片在凯尔格伦 - 劳伦斯分级中为1级和2级。
结果
发现了多种不同病症；70.7%的膝关节存在伴有或不伴有前交叉韧带断裂的半月板退变损伤，9.75%存在股骨和胫骨髁骨坏死，8.54%存在骨赘和关节软骨退变损伤，2.44%存在暂时性骨质疏松，6.1%存在良性肿瘤和囊肿。
结论
在这些“早期骨关节炎膝关节”中存在如此异质性的病症组，可能解释了治疗失败的原因，并且可能证明采用现代MRI成像方法进行正确诊断是合理的。
