OBJECTIVES
Determine the stability of tibial and femoral components of 20 cementless knee arthroplasties with rotating platform.
METHODS
The 20 patients (20 knees) underwent an analysis of dynamic radiographs with an image amplifier and maneuvers of varus and valgus which were compared to static frontal and lateral radiographs of the knees and analyzed by two experienced surgeons in a double-blind way.
RESULTS
We could observe in this study that both methods showed very similar results for the stability of the tibial and femoral components (p<0.001) using the Kappa method for comparison.
CONCLUSION
The tibial component was more unstable in relation to the femoral component in both static and dynamic studies. Level of Evidence IV, Case Series.
目的
确定20例旋转平台非骨水泥型膝关节置换术中胫骨和股骨组件的稳定性。
方法
20例患者（20个膝关节）接受了使用影像增强器的动态X线片分析以及内翻和外翻操作，将其与膝关节的静态正位和侧位X线片进行比较，并由两名经验丰富的外科医生以双盲方式进行分析。
结果
在本研究中，我们观察到使用Kappa方法进行比较时，两种方法在胫骨和股骨组件稳定性方面显示出非常相似的结果（p<0.001）。
结论
在静态和动态研究中，胫骨组件相对于股骨组件都更不稳定。证据等级IV，病例系列。
