概括
在全膝关节整形术 (TKA) 中,功能对齐 (FA) 更频繁地导致中间枢纽运动模式,而不是调整的机械对齐 (aMA). 这种中间枢纽模式与手术后一年患者报告的优异结果有关.
科学领域:
- 整形外科手术 整形外科手术
- 生物机械工程 生物机械工程
- 机器人在医学中的机器人
背景情况:
- 膝关节整形术 (TKA) 的目的是恢复自然的膝关节功能.
- 原生膝盖 flexion 涉及一个中枢的轴心模式,由于骨在骨平原上的差异性回滚.
- 目前的TKA对齐技术包括功能对齐 (FA) 和调整机械对齐 (aMA).
研究的目的:
- 为了比较使用FA与aMA的TKA的动态模式和临床结果.
- 为了确定个性化对齐技术是否会影响TKA中观察到的动力学模式.
- 评估12个月内手术内动力学模式和患者报告的结果指标 (PROM) 之间的关系.
主要方法:
- 一项随机对照试验,涉及60名患者,他们接受机器人辅助的TKA,使用FA (n=29) 或aMA (n=31) 使用十字状支 (CR) 植入物.
- 膝关节动力学的手术内评估,使用试验压力计来记录运动范围内的股骨部件接触点.
- 对接触压力的测量和在12个月后期对PROMs的评估.
主要成果:
- 在58.6%的病例中,FA-TKA组表现出中间枢纽,而aMA-TKA组的比例为19.4% (p < 0.001).
- 侧向旋转模式在aMA-TKA组 (35.5%) 比FA-TKA组 (3.4%) 更常见.
- 患有中枢转运动模式的患者报告了一年PROM优异,而侧向转患者的Kujala分数较低.
结论:
- 与aMA相比,功能对齐 (FA) CR-TKA更频繁地通过软组织平衡产生一个手术期间的中间枢纽动力学模式.
- 调整后的机械对齐 (aMA) 与侧向旋转动力学模式的更高发生率有关.
- 术内动力学模式,特别是中间枢纽,与TKA患者改善的临床结果相关.

Functional Classification of Joints
Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

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 group...
