概括
后侧状骨偏移 (PCO) 的变化与全膝关节整形术 (TKA) 中的延伸间隙没有相关性. 然而,当PCO在两侧都增加时,增加的屈曲收缩与延伸间隙呈现了反向关系.
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
- 重建性手术是一种重建性手术.
背景情况:
- 后骨偏移 (PCO) 是全膝关节整形术 (TKA) 影响关节力学的一个关键参数.
- 介面和侧面PCO变化与由此产生的延伸差距之间的关系需要进一步研究.
- 了解这些关系对于优化TKA结果至关重要,特别是在曲收缩症患者中.
研究的目的:
- 为了比较介质和侧面PCO的变化及其对TKA延伸差距的影响.
- 为了研究增加中侧和侧侧PCO可能会减少延伸间隙的假设,特别是在曲收缩的情况下.
- 阐明PCO变化,曲收缩和延伸间隙差异之间的关系.
主要方法:
- 通过使用修改的间隙技术,对63名接受移动轴承后方稳定TKA的患者进行了回顾性研究.
- 评估中部和侧面PCO变化 (ΔPCO),后骨切割旋转和间隙差异.
- 基于 ΔPCO 变化和与屈曲收缩 (≥15° vs. <15°) 的相关性分析对不同组间隙差异的比较.
主要成果:
- 在任何一个仅基于PCO变化 (P≥0.05) 的组中都没有观察到显著差距差异.
- 在中侧和侧侧PCO增加 (A组) 和双边PCO减少 (C组) 的组中,在≥15° flexion contracture的患者中,观察到显著更大的差距差异.
- 在曲收缩和延伸间隙之间发现了反向相关性,特别是在中侧和侧侧PCO增加的情况下.
结论:
- 中间和侧面PCO的变化与TKA的延伸差距没有直接相关.
- 曲收缩在延伸间隙中起着重要作用,特别是当PCO在两侧增加时.
- 这些发现表明,控制曲收缩对于实现TKA的最佳延伸差距很重要,特别是在双边PCO增加时.

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...
