概括
患有膝关节骨关节炎的患者在行走时,肌底脂肪 (IFP) 的形态变化减少. 这种不够的IFP灵活性可能是膝关节OA进展的关键特征.
科学领域:
- 生物医学工程 生物医学工程
- 整形外科 整形外科 整形外科
- 膝盖生物力学 膝盖生物力学
背景情况:
- 膝关节下脂肪 (IFP) 在通过灵活的形态适应来吸收膝关节内的机械应力方面发挥着至关重要的作用.
- IFP在膝关节关节炎 (OA) 的参与是公认的,但其在行走过程中的动态行为仍然在很大程度上未被探索.
研究的目的:
- 为了调查行走过程中肌底脂肪的形态变化是否在患有膝关节关节炎的个体中表现出明显的特征.
- 要确定改变的IFP动态是否是与膝盖OA相关的特定特征.
主要方法:
- 利用超声波来评估12名膝盖骨关节炎患者和12名健康的年轻/老年志愿者在行走时的IFP形态.
- 量化IFP形态变化 (ΔIFP) 作为立场阶段最大接触和初始接触之间的厚度差异.
- 同步超声波与3D运动分析系统评估膝盖动力学和动力学,包括曲角度和时刻.
主要成果:
- 与健康的年轻 (2.1 ± 0.5 毫米) 和老年 (1.8 ± 0.2 毫米) 志愿者相比,患有膝关节骨质炎的患者的 ΔIFP 显著降低 (1.4 ± 0.3 毫米).
- 在健康的年轻人和老年人对照组之间没有观察到 ΔIFP 的显著差异.
- 在所有组中,IFP值和运动参数 (如膝盖曲角度或步行速度) 之间没有发现显著的相关性.
结论:
- 在行走过程中,皮下脂肪的形态变化减少似乎是膝关节骨关节炎的特征.
- 这些发现表明,受损的IFP动态功能可能有助于膝盖OA的病理生理学.

Bones of the Lower Limb: Femur and Patella
2.1K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Knee Joint

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...
