Fifty-five patients, (30 Rheumatoid Arthritis (RA) and 25 Osteoarthritis (OA], with knee synovial effusion and popliteal cysts, visualized through arthrograms, were studied. A relationship was sought between radiological findings and area of the cysts, measured through a millimeter grid. Ten radiological parameters were graded and summed up to obtain a "total knee score". A "total geode score" was also obtained by scoring, separately, the geodes. In addition two specific indexes were used--for comparison--the erosive index, modified after Berens and Lin, in RA and the Kelligren's index in OA. In RA a statistically significant, inverse correlation was found between the x-ray scores and the area of the cysts, while such a relationship was not observed in OA. However, only a third of the cysts accounted for the inverse relationship in RA. Furthermore, two control groups of RA and OA patients revealed a striking association between degree of radiological damage and frequency of popliteal cysts. Therefore, the hypothesis that popliteal cysts might have a protective effect against the articular-bone damage in RA, can be held only in few cases.
对55例患者进行了研究，其中30例类风湿性关节炎（RA）患者和25例骨关节炎（OA）患者，通过关节造影可观察到膝关节滑膜积液和腘窝囊肿。研究人员探寻了通过毫米网格测量的囊肿面积与放射学检查结果之间的关系。对10个放射学参数进行分级并汇总，以获得“膝关节总分”。还分别对囊肿进行评分，得出“囊肿总分”。此外，为了进行比较，还使用了两个特定指数——RA中经贝伦斯和林修改后的侵蚀指数以及OA中的凯林格伦指数。在RA中，发现X线评分与囊肿面积之间存在统计学上显著的负相关，而在OA中未观察到这种关系。然而，在RA中只有三分之一的囊肿与这种负相关有关。此外，RA和OA患者的两个对照组显示，放射学损伤程度与腘窝囊肿发生率之间存在显著关联。因此，关于腘窝囊肿可能对RA中的关节骨损伤具有保护作用的假设，仅在少数情况下成立。
