概括
膝关节冠状平面对齐 (CPAK) 分类不能可靠地预测膝关节骨关节炎的部斜率,尽管一些组之间的统计差异. 全面的3D评估对于外科手术规划至关重要.
科学领域:
- 整形外科手术 整形外科手术
- 生物医学工程 生物医学工程
- 放射学 放射学是一门学科.
背景情况:
- 膝盖冠状平面对齐 (CPAK) 分类系统根据四肢对齐和关节线倾斜性定义了九种表型.
- 了解CPAK表型和部斜率对于优化全膝关节整形术 (TKA) 规划至关重要.
- 这项研究旨在探索CPAK分类与膝关节骨关节炎患者的中部部斜率之间的关系.
研究的目的:
- 调查膝关节冠状平面对齐 (CPAK) 分类与中侧部斜率之间的相关性.
- 为了确定CPAK表型是否可以预测与全膝关节整形相关的斜腰平面形态.
主要方法:
- 从535名骨关节炎患者中对581个膝盖进行了回顾性分析,这些患者接受了初级TKA.
- 用三维计算机断层扫描 (3D CT) 成像来测量冠状腺对齐和中部骨斜率.
- 统计分析包括多重线性回归,皮尔森相关性和Tukey后期测试的单向ANOVA.
主要成果:
- 多重线性回归显示,冠状线对齐 (CPAK) 和部斜率 (r2 = 0.0233) 之间的相关性很小.
- CPAK分类和关节线斜率解释了只有2.33%的部斜率差异.
- 虽然ANOVA在某些CPAK组 (例如I组与V组和VII组) 之间发现了部斜率的统计学上显著差异,但效应大小非常小.
结论:
- 在骨关节炎膝盖中,CPAK分类和部斜率之间没有临床意义上的关系.
- 观察到的统计差异在测量变化范围内,不会显著影响TKA结果.
- 单靠CPAK分类就不足以预测角平面形态;为了手术规划,需要进行全面的3D评估.

What is Variation?
18.4K
Apart from the measures of central tendency, distribution, outliers, and the changing characteristics of data with time, an important characteristic of any data set is its variation or spread. In some data sets, the data values are concentrated closely near the mean; in others, the data values are more widely spread out from the mean.
The range, standard deviation, standard error, and variance are the different measures of variation.
Range: The range is the difference between its maximum and...

Variation
8.0K
An important characteristic of any set of data is the variation in the data. In some data sets, the data values are concentrated closely near the mean; in other data sets, the data values are more widely spread out from the mean. The most common measure of variation, or spread, is the standard deviation, which is the square root of variance.
When independent and dependent variables are plotted on a scatter plot, the slope of a line is a value that describes the rate of change between the two...

Knee Joint
3.2K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Conservative Site-specific Recombination and Phase Variation
6.8K
Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.
The recognition sites for Cre recombinase called LoxP...

Variation: Normal Distribution, Range, and Standard Deviation
28.2K
In the field of psychology, there are several ways to organize measurements of a trait, feature, or characteristic (i.e., variables). Qualitative data, such as ethnicity, can be tabulated into a frequency count to provide information about the proportion, as well as the variety of groups in a sample or population. On the other hand, researchers can perform a wider set of calculations on quantitative data. The mean, mode, and median, for instance, are central tendency measures to identify a...

Variation of Atmospheric Pressure
4.1K
Change in atmospheric pressure with height is particularly interesting. The decrease in atmospheric pressure with increasing altitude is due to the decreasing gravitational force per unit area as we move away from the surface of the earth.
Assuming the air temperature is constant at a given altitude and that the ideal gas law of thermodynamics describes the atmosphere to a good approximation, one can find the variation of atmospheric pressure with height.
Let p(y) be the atmospheric pressure at...
