概括
在中侧骨带重建过程中添加骨结核介质,改善了骨跟踪,但在坐时增加了中侧膝盖压力. 需要进一步的研究来确定最佳的候选患者.
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
- 计算建模计算建模
背景情况:
- 带不稳定通常涉及横向的误导,需要手术干预.
- 中侧骨带 (MPFL) 重建是骨不稳定的常见治疗方法.
- 与MPFL重建相结合的骨结核细胞媒介化的作用需要进一步研究.
研究的目的:
- 为了评估是否添加骨结核中介化MPFL重建减少横向骨在动态活动期间的maltracking.
- 为了确定什么时候在坐等日常活动中,中间骨骨接触压力升高.
主要方法:
- 模拟了七个带有骨不稳定的计算膝盖模型.
- 进行了MPFL重建,随后在每个模型中添加了小腿结核细胞媒介.
- 模拟包括用于动态运动分析的旋转着陆和用于压力分析的膝盖.
主要成果:
- 在旋转过程中,添加小腿结节介质化显著降低了侧面带错位 (截肢偏移指数).
- 在模拟坐过程中,部结核的介质化显著增加了中间骨骨接触压力.
- 在一些单独的MPFL重建模型中发生了带位,但在增加媒介化的情况下较少发生.
结论:
- 虽然骨的介质化改善了动态运动期间的骨跟踪,但它也增加了坐时的介质软骨压力.
- 仅仅MPFL重建可能不会在所有情况下足够地解决带错误跟踪.
- 这些发现表明,通过结合外科手术技术,改善跟踪和增加中间压力之间存在权衡.

Bones of the Lower Limb: Femur and Patella
2.6K
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
1.9K
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...

Muscles that Move the Leg
2.0K
The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...
