概括
计算机导航全膝关节整形术 (CN-TKA) 对膝关节形有效,显示了与膝关节相似的早期临床结果. 这种导航技术确保了精确的组件放置和良好的软组织平衡在valgus膝盖病例.
科学领域:
- 整形外科手术 整形外科手术
- 生物医学工程 生物医学工程
- 医疗成像医学成像
背景情况:
- 计算机导航全膝关节整形术 (CN-TKA) 提高了骨切割,软组织平衡和部件定位的精度.
- 需要进一步研究CN-TKA对纠正膝关节形的疗效.
研究的目的:
- 为了评估CN-TKA在形膝盖形的适用性.
- 为了比较CN-TKA在valgus膝盖和varus膝盖中的结果.
主要方法:
- 分析了74个保持十字体的CN-TKA (20个valgus,54个varus).
- 在各种压力条件下评估了手术内关节松.
- 手术后的放射学参数 (HKA,FTA等) 和临床分数 (KOOS,Lysholm) 在一年后进行测量.
主要成果:
- 与关节膝关节相比,Varus膝关节在全延伸方面表现出明显更大的横向松 (p=0.011).
- 瓦尔古斯膝盖在90°屈曲时表现出明显更大的中间松度,而不是瓦鲁斯膝盖 (p=0.004).

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...
