PURPOSE
To compare the measured resection technique and the gap balancing technique for correction of the femoral rotational alignment.
METHODS
57 women and 6 men (mean age, 70 years) with end-stage osteoarthritis and <15º malalignment and <10º flexion contracture of the knee underwent primary total knee arthroplasty through the medial approach using the measured resection technique (n=34) or the gap balancing technique (n=29). Femoral rotational alignment was evaluated before and 7 days after surgery using computed tomography by referencing the 2 posterior condyles to the transepicondylar axis.
RESULTS
The 2 groups did not differ significantly in terms of correction of the femoral rotational alignment (3.4º ± 1.4º vs. 3.5º ± 3.1º, p=0.817).
CONCLUSION
The measured resection and the gap balancing techniques achieved comparable correction of femoral rotational alignment.
目的
比较测量截骨技术与间隙平衡技术在纠正股骨旋转对线方面的效果。
方法
57名女性和6名男性（平均年龄70岁），患有终末期骨关节炎，膝关节畸形小于15°，屈曲挛缩小于10°，通过内侧入路采用测量截骨技术（n = 34）或间隙平衡技术（n = 29）进行初次全膝关节置换术。术前及术后7天采用计算机断层扫描，通过将两个后髁与经髁间轴进行参照来评估股骨旋转对线情况。
结果
两组在股骨旋转对线的纠正方面无显著差异（3.4°±1.4°对3.5°±3.1°，p = 0.817）。
结论
测量截骨技术和间隙平衡技术在股骨旋转对线的纠正方面效果相当。
