概括
调查后脚和前脚变动对膝盖生物力学的影响,发现全脚变动显著减少膝盖中间位移和膝盖外附动力. 最佳的内设计可能有利于膝关节骨关节炎患者.
科学领域:
- 生物力学 生物力学
- 整形外科 整形外科 整形外科
- 运动医学 运动医学
背景情况:
- 侧内传统上旨在减少膝关节外接引力时刻 (EKAM).
- 后脚和前脚变动对膝盖位移和脚部压力的特定生物力学影响尚未完全理解.
- 了解这些影响对于优化内设计,以应对膝关节关节炎等疾病至关重要.
研究的目的:
- 调查不同程度的后脚和前脚变动对膝盖位置和旋转移位的影响.
- 分析不同变化条件下的足部压力分布和脚部不适的变化.
- 为了确定反转角和EKAM时刻臂的下降之间的关系.
主要方法:
- 26名健康参与者站在受控姿势中.
- 从0到10度以2度的增量进行后脚转变.
- 前脚的反转角度从0度到后脚的反转角度分别增加2度.
- 在每个角度测量了膝盖中位移,EKAM瞬间臂,脚部压力和脚部不适.
主要成果:
- 只有后脚和整个脚的变形都显著增加了膝盖中间位移,并减少了EKAM的动力臂.
- 与仅用于后脚的变形相比,全脚变形对膝盖位移和EKAM时刻臂减小的效果更为明显.
- 在每一个后脚转动角度上增加前脚转动,进一步增强了中间膝盖位移和EKAM时刻臂减小.
- 侧面前脚压力随着前脚更高的转向角度显著增加,特别是在更大的后脚转向角度.
- 脚部不适随着更高的反转角度而升级,特别是在整个脚的反转角度和更高的后脚反转角度.
结论:
- 后脚和整个脚的变形显著改变了膝盖的生物力学,通过增加中间位移和减少EKAM动力臂.
- 优化的内配置,特别是6-10度的后脚变动与前脚变动相对于后脚角度的40-60%相结合,可以提供卓越的生物力学支持.
- 这些发现表明,通过定制的内设计,结合特定的变形参数,可以改善膝关节骨关节炎的管理.

Muscles of the Leg that Move the Foot and Toes
1.5K
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....

Knee Joint
1.8K
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...

Ankle Joint
1.6K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Bones of the Lower Limb: Femur and Patella
2.5K
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...

Bones of the Lower Limb: Tibia and Fibula
3.5K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
