概括
测量在全膝关节整形术 (TKA) 中插入试验组件所需的力并不可靠地表明正确的组件厚度. 这种推力方法无法确定所有TKA设计的最佳插入厚度.
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
- 生物力学 生物力学
背景情况:
- 膝关节整形术 (TKA) 的目的是恢复本地膝关节功能.
- 准确的插件厚度对于防止硬或不稳定至关重要.
- 目前用于确定插件厚度的方法包括主观松度评估和定量度,但有局限性.
研究的目的:
- 调查测量试验插件放置期间推力力量的潜力,作为一种用于确定TKA中正确的脚插件厚度的新方法.
- 为了评估峰值推力是否与动力调整的TKA中的插件厚度相关.
主要方法:
- 这项研究涉及30名接受动力调整TKA的患者.
- 测量了试验插件的推力,这些插件比外科医生确定的正确厚度薄1毫米,比外科医生确定的正确厚度厚1毫米.
- 使用了一种特定的TKA插件设计,具有中间球合性和后十字带保留.
主要成果:
- 平均峰值推力为127±104 N (1毫米更薄),127±95 N (正确),以及144±96 N (1毫米更厚).
- 在测试的插件厚度 (p=0.3210) 中,平均峰值推力没有统计学上显著的差异.
- 测量的力不能在正确和不正确的插入厚度之间进行一致的区别.
结论:
- 测量用于安装骨试验插件所需的峰值力不是确定TKA中正确插件厚度的可靠方法.
- 这种推力力方法不适合所有插件设计,特别是那些具有中间球入插孔一致性的插件.
- 可能需要进一步的研究来探索优化TKA插件选择的其他客观措施.

01:16Bones of the Lower Limb: Femur and Patella
2.4K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

01:10Bones of the Lower Limb: Tibia and Fibula
3.2K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

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...
