概括
患有膝关节关节炎的患者表现出较差的下肢冠状元对齐对称性. 逆侧肢是不可靠的指导全膝关节整形术 (TKA) 冠状位置由于低的一致率.
科学领域:
- 整形外科手术 整形外科手术
- 生物机械分析 生物机械分析
- 放射性成像学成像学
背景情况:
- 膝关节关节炎 (OA) 显著影响下肢生物力学.
- 精确的冠状元对齐对于成功的全膝关节整形术 (TKA) 结果至关重要.
- 反侧肢体对称性通常被假定为外科计划.
研究的目的:
- 为了评估膝盖OA患者下肢冠状元对齐的对称性.
- 为了确定相对侧肢是否可以可靠地指导TKA冠状位置.
- 评估手术肢体和逆侧肢体之间的TKA对齐一致率.
主要方法:
- 多中心,横截面的观察性研究.
- 在76名膝关节骨髓炎患者的手术前全腿支力X射线图的分析.
- 测量放射性参数 (例如HKA,CPAK,FMA,TMA) 和评估冠状元对齐对称性.
主要成果:
- 对于关节 - 膝盖 - 脚 (HKA) 分类的低操作-对抗对应度 (57%).
- 根据手术膝盖的对齐情况,一致性有显著的变化 (中性:81%, varus:58%, valgus:27%).
- 膝盖冠状平面对齐 (CPAK) 和表型分类显示出差的一致性 (分别为38%和11%).
结论:
- 在膝盖骨关节炎患者的下肢冠状元对齐中存在显著的不对称性.
- 反侧四肢对齐不是TKA冠状位置的可靠参考.
- TKA手术规划不应该仅仅依赖于对侧肢数据来进行冠状元对齐.

Bones of the Lower Limb: Femur and Patella
4.8K
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...

Eccentric Axial Loading in a Plane of Symmetry

Eccentric axial loading occurs when an axial load is applied away from the centroidal axis of a structural member. This scenario is common in engineering, where structural elements may not be directly aligned due to various design or functional requirements.

Knee Joint
3.1K
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...
