Abstract
OBJECTIVES
We assessed the accuracy of an extramedullary guide system for femoral component alignment in TKA.
METHODS
We retrospectively analysed 87 total knee arthroplasties using a newly developed extramedullary guide system.
RESULTS
Correct postoperative coronal plane femoral component, with deviation from neutral alignment by 3° or less, was found in 87% of the study population. The percentages were 100%, 91% and 79% for HKA of 0-3°, 3-10° and >10°respectively.
CONCLUSION
The correct use of the extramedullary guide system allows the restoration of the neutral mechanical axes of the lower limb, especially in cases of limited varus deformity.
摘要
目的
我们评估了一种用于全膝关节置换术（TKA）中股骨组件对线的髓外导向系统的准确性。
方法
我们回顾性分析了87例使用新开发的髓外导向系统进行的全膝关节置换术。
结果
在87%的研究人群中发现术后股骨组件在冠状面正确，与中立对线的偏差在3°或更小。对于髋膝角（HKA）为0 - 3°、3 - 10°和>10°的情况，百分比分别为100%、91%和79%。
结论
正确使用髓外导向系统可恢复下肢的中立机械轴，尤其是在轻度内翻畸形的情况下。
