概括
总膝盖置换植入物通常与越南妇女的膝盖尺寸不匹配. 这项研究强调了需要更适合的假肢来改善全膝关节整形术患者的结果.
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
- 人体解剖学 解剖学 解剖学
背景情况:
- 膝盖尺寸和全膝关节置换 (TKR) 植入物尺寸之间的不匹配可能导致患者的不理想结果和不满.
- 评估特定的人口群体,如越南妇女,对于优化TKR程序至关重要.
研究的目的:
- 用3D建模来描述越南妇女的膝关节形态.
- 评估目前可用的TKR假肢与这一人口群的本地膝盖解剖学的兼容性.
主要方法:
- 利用全腿CT扫描数据集创建3D膝关节模型.
- 基于机械对齐的模拟股骨和骨切除.
- 切除表面的测量前后 (AP) 和中侧 (ML) 尺寸.
- 分析了六种不同的TKR假肢系统的适合度和覆盖率.
主要成果:
- 分析了40名患有骨关节炎的女性患者 (51-79岁) 的数据.
- 确定了平均偏远大腿骨尺寸 (AP: 63.07 ± 3.05 毫米,ML: 57.46 ± 3.06 毫米) 和靠近骨尺寸 (AP: 48.95 ± 3.01 毫米,ML: 67.14 ± 3.49 毫米).
- 观察到股骨面积比 (ML/AP) 与膝盖尺寸的变化以及骨AP和ML尺寸之间的权衡.
- 发现即使有最佳的不匹配公差 (±1.5 mm AP,±3 mm ML),最好的股骨部件合适度也只有67.5%.
- 最好的部件匹配实现了92.5%的覆盖率,在AP和ML尺寸的±3毫米公差下.
结论:
- 越南妇女的膝盖形态与目前可用的TKR假肢尺寸之间存在重大差异.
- 有明显的临床需要开发专门针对越南妇女的解剖特征的TKR植入物设计.
- 进一步的研究对于设计和验证更适合这个人群的假肢解决方案至关重要.

Bones of the Lower Limb: Femur and Patella
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 neck...
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...
