概括

固定轴承 (FB) 单隔膜膝关节整形术 (UKA) 与本土膝关节相比,显著扩大侧面隔膜关节空间,而移动轴承 (MB) UKA显示的结果更接近自然膝关节生物力学. 这对理解潜在的UKA并发症有影响.

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
医疗成像医学成像

背景情况:

骨关节炎在侧腔部的进展是经过中部单隔膜膝关节关节整形术 (UKA) 修订后的已知并发症.
之前对骨关节接触的分析是有限的;需要全面了解膝盖运动期间的关节空间.
固定轴承 (FB) 和移动轴承 (MB) 的UKA设计可能会以不同的方式影响横隔间关节空间动态.

研究的目的:

在接受FB或MB UKA的患者中,在单腿冲刺期间动态地绘制侧面隔间关节空间.
为了将这些关节空间与对侧本土膝盖的空间进行比较.
为了测试后UKA膝盖的假设,与本地膝盖相比,关节空间呈现显著变化.

主要方法:

计算机断层扫描从12名单边中间FB UKA患者和11名单边中间MB UKA患者获得.
一个双光镜成像系统捕获了单腿肺部,用于动作可视化的2D到3D注册.
在部和大腿部表面的侧侧关节空间被计算和绘制为本地,FB UKA和MB UKA膝盖.

主要成果:

与本地膝关节相比,FB UKA膝关节的中间,侧面,中心和后部关节空间显著增加 (p <0.05).
MB UKA膝盖仅在中央和后部关节空间 (p <0.05) 中表现出显著增加.
与MB UKA相比,FB UKA导致中间,中央和后关节空间的增加更大;与骨对齐和患者报告的得分发现了相关性.

结论:

动态关节空间分析可以更深入地了解UKA之后的接触力学.
FB UKA导致关节空间扩大,而MB UKA保持更接近本地膝关节配置的关节空间.
这些发现对于理解和潜在地减轻与UKA相关的术后并发症至关重要.

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...

Structural Joints: Synovial Joints

Structural Joints: Synovial Joints

Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...

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...
