概括
患者年龄在全膝关节整形术 (TKA) 后显著影响冠状元对齐变化. 较年轻的患者经历了静脉漂移,而较年长的患者显示出最小的对齐移动,这对于手术规划至关重要.
科学领域:
- 整形外科手术 整形外科手术
- 生物机械分析分析
- 放射性成像 放射性成像 放射性成像
背景情况:
- 冠状元对齐对于全膝关节整形术 (TKA) 的结果至关重要.
- 了解TKA后的姿势对齐变化对于长期功能至关重要.
- 患者年龄对TKA后冠状元对齐转移的影响需要进一步调查.
研究的目的:
- 为了确定患者的年龄是否能缓和冠状-膝-脚 (HKA) 对齐,在TKA后,卧卧和站立的位置之间发生了变化.
- 评估年龄对膝关节置换手术后姿势调整变化的程度的影响.
主要方法:
- 一项涉及113名患者的横截面研究,这些患者接受了骨关节炎的初级TKA.
- 为了测量姿势变化 (ΔHKA),在仰卧和站立的位置进行了标准化的全身射线图.
- 带有限制立方线的线性混合效应模型分析了年龄和 ΔHKA 之间的关联,对共变量进行调整;对老年患者进行了等效测试.
主要成果:
- 年轻的患者表现出显著的立体漂移 (2-3°),随着年龄的增长而减少.
- 观察到一个显著的年龄位置相互作用 (p=0.011).
- 60岁及以上的患者的平均DHKA值为-0.01°,统计学上相当于没有变化,在±1°的范围内.
结论:
- 在TKA后的姿势冠状元对齐变化显著取决于患者的年龄.
- 年轻的TKA患者表现出可测量的静脉漂移,而老年患者表现出可以忽略的对齐变化.
- 患者年龄是一个关键因素,在规划手术内对齐策略时需要考虑,以获得最佳的TKA结果.

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

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...

01:29Bone Disorders
5.1K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
