概括
这项研究发现,在接受全膝关节整形手术 (TKA) 的印度患者中,平均后侧状角 (PCA) 明显低于标准的3°外侧旋转. 图像引导的机器人可以帮助复制患者特定的PCA以改善结果.
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
- 放射学 放射学是一门学科.
背景情况:
- 在全膝关节整形术 (TKA) 中,适当的股骨部件对齐对于正常的骨骨 (PF) 动力学至关重要.
- 标准的3°外转相对于后侧状轴 (PC轴) 可能不是普遍适用的.
- 在功能上对齐的膝盖中对患者特定的股骨部件旋转需要进一步调查.
研究的目的:
- 为了检查印度患者的Transepicondylar轴 (TEA) 和PC轴 (后部心状角 - PCA) 之间的关系.
- 在这个人群中确定影响PCA的因素.
- 评估使用图像引导机器人复制患者特定PCA的可行性.
主要方法:
- 对40名患者 (52个膝盖) 的前性评估,这些患者患有原发性关节炎和形变形.
- 基于CT的J计划器用于确定本地PCA.
- 术前和术后评估形状,PF倾斜,PF转移,大腿部部件旋转,形跟踪,以及功能/放射性结果.
主要成果:
- 平均PCA为1.9° (范围:0°-7.3°),大多数膝盖都低于通常的3°.
- 在手术前的骨倾斜平均为5.63°,在手术后降至4.43°.
- 大多数患者获得了优异的功能评分,并发症率低.
结论:
- 研究的印度人群中的PCA与标准的3度外部旋转有显著差异.
- 图像引导的机器人可以识别和复制患者特定的PCA,特别是在可减小的形变形的情况下.

Bones of the Lower Limb: Femur and Patella
8.1K
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...

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...
