概括

在全膝关节整形手术中,不对称的骨复苏可能会改变关节机制. 中厚斜骨的厚度增加了骨关节的不良跟踪和中央脊柱压力,可能导致并发症.

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
生物医学研究的研究.

背景情况:

骨关节 (PFJ) 并发症是膝盖全关节整形术 (TKA) 后不满和修复手术的重要原因.
在TKA期间不对称的皮切除可能会对PFJ生物力学和动力学产生不利影响.

研究的目的:

用尸体模型研究状曲对PFJ动力学和接触力的影响.
为了评估不同的骨切除厚度 (中性,中间厚斜,侧面厚斜) 如何影响PFJ机制.

主要方法:

使用11个新鲜冷的尸体膝盖,模拟被动曲和楼梯下降使用机器人系统.
通过光学跟踪和接触力测量PFJ动力学,使用校准的三区传感器.
使用克鲁斯卡尔-瓦利斯试验分析数据,与邦费罗尼调整后期比较.

主要成果:

与中立和侧面厚厚的条件相比,中等厚度的斜面骨表面重新覆盖导致了在被动曲和楼梯下降期间增加中介化和内部旋转.
中央的压力 (C2) 在被动曲过程中在中间厚斜组与侧侧厚斜组相比显著更高,在楼梯下降过程中与中性和侧侧厚斜组相比.
两组之间没有观察到总体复合PFJ力中的显著差异.

结论:

骨曲,特别是中厚曲,改变了PFJ跟踪和区域负荷,即使不增加总关节力,也会增加中心脊压.
建议进行对称形切除,以减轻失踪和焦点过载,从而降低TKA后PFJ相关症状的风险.

Bones of the Lower Limb: Femur and Patella

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...

Knee Joint

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...
