概括
接受前十字带重建 (ACLR) 的患者,四头肌 (QT) 或肌 (PT) 自体移植,在垂直跳跃中表现出类似的生物力学. 这两组都显示了手术肢体的卸载模式,这表明QT可能是一个可行的替代移植.
科学领域:
- 整形外科手术 整形外科手术
- 运动医学 运动医学
- 生物力学 生物力学
背景情况:
- 前交叉带重建 (ACLR) 旨在恢复膝盖功能.
- 四头肌 (QT) 和肌 (PT) 自体移植是ACLR的常见选择.
- 了解移植类型之间的生物力学差异对于优化患者的治疗结果至关重要.
研究的目的:
- 为了比较使用 QT 和 PT 自体移植的 ACLR 患者之间的垂直跳 (DVJ) 降落任务的生物力学.
- 在这些患者群体中评估与DVJ表现相关的功能结果.
主要方法:
- 在手术后6个月至2年内参与的身体活跃的患者 (n=24) 具有初级ACLR (QT=14,PT=10).
- 参与者在生物力学实验室进行DVJ.
- 分析了峰值垂直地面反应力 (VGRF) 和下肢关节动力学和动力学.
主要成果:
- 在QT和PT自移植组之间没有观察到统计学上显著的生物力学差异.
- 这两组在手术肢体中的VGRF峰值明显低于非手术肢体.
- 在每组内比较手术和非手术肢体时,观察到动力变量的中大效果大小.
结论:
- 接受ACLR的患者,无论移植类型 (QT或PT) 是什么,都会在DVJ期间在手术肢体中表现出一种卸载模式.
- 由于QT和PT组之间没有显著的生物力学差异,这表明QT是ACLR可行的替代移植来源.
- 进一步的研究可以探索长期的功能结果和患者报告的满意度.

Bones of the Lower Limb: Femur and Patella
8.2K
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
3.4K
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...
