Abstract：
UNASSIGNED: In total knee replacement component alignment is a very crucial parameter to achieve better clinical outcomes. Only a few studies exist in the literature on the association between sagittal alignment of components and clinical outcomes. The study aimed to measure the functional outcome and association between the sagittal alignment of total knee replacement components and their clinical outcome.
UNASSIGNED: Prospectively we collected data of 81 knees (cases) following total knee replacement. The sagittal femoral angle, anterior and posterior tibial slopes were assessed on 2nd postoperative week using a lateral radiograph. Based on these measures 2 groups were made. Group A comprises of the femoral component which was further divided into A1 (41 cases) and A2 (40 cases) based on the component\'s sagittal femoral angle in flexion or extension.Group B comprises of Tibial component subgrouped based on the degree of Tibal angle as the posterior tibial slope or anterior tibial slopes. The B1 subgroup has posterior tibial slope of more than 5° (23 cases), B2 posterior tibial slope within 5° (53 cases), and B3 anterior tibial slope (5 cases). Preoperative and follow-ups at one month, 6 months, and 3 year; the functional assessment was performed using the American Knee Society score and Oxford knee scores. The duration to raise the leg straight (in days) was also measured.
UNASSIGNED: 52 patients (81 total knee replacement cases) with a mean age of 62.88 ± 8.21 were enrolled. Results showed significant improvement in mean American Knee Society score (preoperative 32.91 ± 2.61 to 86.68 ± 2.52 postoperatively at 3 years; P < 0.001) and mean Oxford knee score (preoperative 34.69 ± 1.06 to 19.20 ± 1.91 postoperatively at 3-years; P < 0.001). The correlation of American Knee Society score between the femoral component angle and tibial component angle suggested that the maximum correlation was between Group A2 (Femoral angle = 91 to 95) and Group B2 (Tibal angle = 86 to 90), with p-value <0.0001.
UNASSIGNED: There is a positive association between the proper sagittal alignment of femoral component and tibial component in total knee replacement with clinical outcome. The functional outcome (in terms of mean American Knee Society score) is better when the femoral component is positioned in extension and the posterior tibial slope of less than 5° is achieved.

摘要：
■在全膝关节置换组件对准是实现更好临床结果的非常关键的参数。在文献中，只有少数研究关于成分的矢状排列与临床结果之间的关联。该研究旨在测量全膝关节置换组件的矢状排列与其临床结果之间的功能结果和关联。
■我们收集了全膝关节置换后81个膝关节（病例）的数据。股骨矢状角,术后第2周使用外侧片评估胫骨前后斜度。基于这些措施，进行了2组。A组包括股骨组件，根据组件的屈曲或伸展矢状角将其进一步分为A1（41例）和A2（40例）。B组包括胫骨组件，该组件根据胫骨后角或胫骨前角的角度进行分组。B1亚组胫骨后倾角大于5°（23例），B2胫骨后坡5°以内（53例），B3胫骨前斜度(5例)。术前和随访一个月，6个月,和3年;使用美国膝关节协会评分和牛津膝关节评分进行功能评估。还测量了伸直腿的持续时间(以天为单位)。
■52例患者（81例全膝关节置换病例），平均年龄为62.88±8.21。结果显示，美国膝关节协会平均评分（术前3年为32.91±2.61至86.68±2.52；P<0.001）和牛津膝关节平均评分（术前3年为34.69±1.06至19.20±1.91；P<0.001）均有显着改善。股骨组件角度与胫骨组件角度之间的美国膝关节协会评分的相关性表明，最大相关性在A2组（股骨角度=91至95）和B2组（胫骨角度=86至90）之间。p值<0.0001。
■在全膝关节置换中，股骨组件和胫骨组件的正确矢状排列与临床结果之间存在正相关。当股骨组件处于伸展位置并且胫骨后倾角小于5°时，功能结果（就美国膝关节协会的平均评分而言）更好。
