概括
在全膝关节整形术 (TKA) 中的动力对齐 (KA) 显示了与机械对齐 (MA) 的中期结果相似的结果. 虽然KA可能提供统计学上显著的患者报告的益处,但临床意义各不相同,长期数据有限.
科学领域:
- 整形外科手术 整形外科手术
- 生物机械工程 生物机械工程
- 临床结果研究研究
背景情况:
- 全膝关节整形术 (TKA) 是一种常见的治疗晚期膝关节关节炎的手术.
- 存在两个主要的对齐哲学:用于中性四肢轴的机械对齐 (MA) 和用于本地膝盖恢复的动力对齐 (KA).
- 在TKA中,KA和MA之间的中期结果比较需要进行系统的评估.
研究的目的:
- 在初级全膝关节整形术 (TKA) 中,系统地审查和评估动力对齐 (KA) 与机械对齐 (MA) 的中期结果 (≥2年) 的比较.
- 评估患者报告结果 (PROMs),运动范围 (ROM),X线图对齐,步态,并发症和生存率的差异.
主要方法:
- 对电子数据库 (MEDLINE,Embase,Cochrane CENTRAL) 和谷歌学者进行系统审查.
- 包括16项评估中期结果的初级比较研究.
- 评估PROMs,ROM,X光线对齐,步态参数,并发症和植入物存活率.
主要成果:
- 在KA和MA之间,中期ROM是可比的.
- 在一些PROM (牛津膝关节得分,WOMAC) 中,KA显示了统计学上显著的改善,尽管临床意义各不相同.
- 放射性对齐与KA哲学一致,没有不良影响;步态差异是不可重现的;修订率低 (0-2%),对生存率的比较能力有限.
结论:
- 动力对齐 (KA) 在初级全膝关节整形术 (TKA) 中实现的中期临床结果与机械对齐 (MA) 一般相似.
- 虽然一些研究报告了KA的统计学上显著的PROM改善,但这些可能不会始终达到最小的临床重要差异.
- 对KA的长期耐用性数据有限,需要进一步调查无菌松风险.

Design Example: Alignment of a Road Line Using GIS
351
The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...

Aligning actions are communicative strategies individuals employ to maintain social harmony and preserve personal identity in the face of potential disruptions to social norms. These actions are particularly important in managing social impressions when one's behavior might be seen as inappropriate, incompetent, or morally questionable.Types of Aligning ActionsThe three principal types of aligning actions are disclaimers, accounts, and apologies.DisclaimersDisclaimers are preventive; they are...

Mechanical Protein Functions
5.7K
Proteins perform many mechanical functions in a cell. These proteins can be classified into two general categories- proteins that generate mechanical forces and proteins that are subjected to mechanical forces. Proteins providing mechanical support to the structure of the cell, such as keratin, are subjected to mechanical force, whereas proteins involved in cell movement and transport of molecules across cell membranes, such as an ion pump, are examples of generating mechanical force.

Long-term Depression
33.3K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Review and Preview
8.4K
In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
