概括

膝关节整形术 (TKA) 患者的结果随着更大的运动范围和在深跪和步进活动期间的特定旋转运动而改善. 实现这些动力学目标可以提高TKA后的患者满意度和功能.

科学领域:

整形外科手术整形外科手术
生物力学生物力学
医疗器械工程医疗器械工程

背景情况:

一部分全膝关节整形术 (TKA) 患者报告不满,特别是对高要求的活动,如深膝跪和步进.
这些活动需要特定的动力学参数,在TKA之后可能会受到损害.

研究的目的:

研究TKA后的步进和深跪任务中的膝盖动力学与患者报告的结果测量 (PROMs) 之间的相关性.

主要方法:

64名TKA患者在至少1年的随访后被评估.
使用光学和3D CAD模型捕捉了步行和深跪的体内动力学.
分析了动力学和PROM (牛津膝关节得分,美国膝关节协会得分,满意度,疼痛) 之间的关联.

主要成果:

较高的牛津膝关节分数与跪下时增加的外部旋转和附加,以及升级时的外部旋转相关.
改善美国膝关节协会的得分与步进过程中更大的内部-外部旋转有关.
增加的外科满意度和减少的疼痛与两个任务期间更大的曲和特定的旋转运动有关.

结论:

完整的运动范围和可控的范围末端旋转是影响TKA后患者结果的关键动力学参数.
未来的TKA植入物设计和康复方案应优先实现这些动力学目标,以提高患者的满意度和功能.

关键词:

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...

Rotation with Constant Angular Acceleration - II

Rotation with Constant Angular Acceleration - II

Kinematics is the description of motion. The kinematics of rotational motion discusses the relationships between rotation angle, angular velocity, angular acceleration, and time. One can describe many things with great precision using kinematics, but kinematics does not consider causes. For example, a large angular acceleration describes a very rapid change in angular velocity without any consideration of its cause. Thus, rotational kinematics does not represent the laws of nature.
The first...
