概括

关节骨关节炎患者在站立时体重分布不均. 整体关节置换平衡了这种负载,改善了关节功能,并表明需要以姿势为重点的物理治疗.

科学领域:

整形外科整形外科整形外科
生物力学生物力学
老年病的医生老年病的医生

背景情况:

关节骨关节炎在老年人中很普遍,通常需要进行全关节置换.
在关节骨关节炎患者的双脚姿势机制尚不清楚.
对于经常休息的老年人来说,了解静止期间的负载分布至关重要.

研究的目的:

在单侧关节骨关节炎患者的双脚姿势期间调查关节和膝关节关节的时刻分布.
评估关节全置换术后一年负荷分布的变化.

主要方法:

在双脚姿势时收集了动力学和动力学数据.
计算了外部部和膝盖引的时刻.
用对称角度评估肢体负荷分布.

主要成果:

在手术前,未受影响的肢体承受了10%的重量,并具有更高的引时刻.
在术后,没有观察到肢体之间的负载分布有显著差异.
部引时刻的变化与地面反应力和部引角度有关;姿势宽度影响了受影响的四肢时刻.

结论:

单侧关节骨关节炎导致在双脚姿势时不对称的机械负载分布.
整体关节置换有效地使四肢之间的负载分配正常化.
预防性治疗应解决双脚姿势,以促进平衡的四肢负荷.

Bones of the Lower Limb: Femur and Patella

Bones of the Lower Limb: Femur and Patella

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

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...
