概括
在全膝关节整形术 (TKA) 中,中侧附带带松的增加与较大的形变形有关. 然而,带松的显著变化凸显了膝盖解剖学对于精确的TKA对齐的复杂性.
科学领域:
- 整形外科手术 整形外科手术
- 生物力学 生物力学
- 关节质整术是指关节质整术.
背景情况:
- 膝关节整形术 (TKA) 的目的是恢复膝关节的功能和对齐.
- 了解体内带松对于实现最佳TKA结果至关重要.
- 机器人辅助的TKA允许精确评估关节力学.
研究的目的:
- 在体内评估全膝关节整形术 (TKA) 患者的中间和侧面关节松.
- 为了将关节松与各种TKA对齐参数相关联,包括部-膝盖-脚角,近亲角和远距离的股骨角.
- 在接受机器人辅助TKA的患者中分析这些关系.
主要方法:
- 在805个机器人辅助TKA中使用动态带张力器测量了带张力.
- 患者根据中性到严重的静脉位 (0°至≥14°) 进行分组.
- 在考虑MPTA和LDFA时,在对齐组中比较了中间和侧侧附带带分心.
主要成果:
- 中间附带带的分心随着较大的形变形显著增加 (中性的4.0毫米到≥14°的形变形的8.7毫米).
- 侧侧侧侧带的分心在延伸和屈曲方面都减少,随着变量的增加.
- MPTA和LDFA影响了中间分心能力,但在所有组中都观察到带拉伸的显著变化.
结论:
- 在TKA中增加形变形与增加的中间带分心能力有关.
- 带松的显著跨组和内组变异性突显了膝盖软组织解剖学的复杂性.
- 解剖学TKA不仅需要恢复对齐,还需要原生软组织张力.

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...

Ankle Joint
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...
Stability of structures
In mechanical engineering, the stability of systems under various forces is critical for designing durable and efficient structures. One fundamental way to explore these concepts is by analyzing systems like two rods connected at a pivot point, O, with a torsional spring of spring constant k at the pivot point. This system is similar in appearance to a scissor jack used to change tires on a car. In this case, the arms of the linkage (equivalent to the rods in this system) are entirely vertical,...
