The total knee arthroplasty (TKA) has been shown to be a successful and cost-benefit procedure in terms of pain improvement in patient with symptomatic knee osteoarthritis. However, almost a 20% of the patients are not satisfied with the result of the surgery.
We have carried out a transversal unicentric cases controls study with clinical cases of the own hospital, obtained by a clinical records revision. A total of 160 patients with a TKA with at least 1 year of follow-up were selected. Demographic variables, functional scales (WOMAC and VAS) and rotation of the femoral component through the analysis of the images obtained by CT scan were collected.
The total was 133 patients that was divided in two groups. A control group and pain group. The Control group was made up of 70 patients with a mean age of 69.59 years (23 men and 47 women) and the pain group was made up of 63 patients with a mean age of 69.48 years (13 men and 50 women). We didn't find difference regarding the analysis of the rotation of the femoral component. In addition, we were not found significant differences when applying a stratification by sex. And, the analysis of the malrotation of the femoral component, previously defining limits of value rotation considered as extreme, in any of the case did not show significant differences.
The results of the study confirm that malrotation of the femoral component had no influence on the presence of pain at a minimum of one year of follow-up after TKA implantation.
全膝关节置换术（TKA）已被证明是一种成功且具有成本效益的手术，对于有症状的膝关节骨关节炎患者，能有效改善疼痛。然而，近20%的患者对手术结果不满意。
我们通过回顾临床记录，对本院的临床病例进行了一项横向单中心病例对照研究。共选取了160例接受TKA且随访至少1年的患者。收集了人口统计学变量、功能量表（WOMAC和VAS）以及通过CT扫描图像分析得出的股骨部件旋转情况。
总计133例患者被分为两组，即对照组和疼痛组。对照组由70例患者组成，平均年龄69.59岁（23名男性和47名女性），疼痛组由63例患者组成，平均年龄69.48岁（13名男性和50名女性）。在分析股骨部件旋转情况时，我们未发现差异。此外，按性别分层时也未发现显著差异。而且，在任何情况下，对股骨部件旋转不良进行分析（预先定义被视为极端的旋转值极限）均未显示出显著差异。
研究结果证实，在TKA植入后至少1年的随访中，股骨部件旋转不良对疼痛的存在没有影响。
