概括

膝关节冠状平面对齐 (CPAK) 在全膝关节整形术 (TKA) 中对带关节缺口的预测能力有限. 直接测量关节间隙对于准确的手术规划和改善TKA结果至关重要.

科学领域:

整形外科手术整形外科手术
生物机械分析分析
医学成像医学成像

背景情况:

延伸和曲的最佳中侧平衡对于成功的全膝关节整形术 (TKA) 至关重要.
目前的膝盖分类工具,如膝盖冠状平面对齐 (CPAK),不包括关节的软组织形状.
了解骨骨关节间隙对于TKA规划至关重要.

研究的目的:

为了评估跨不同CPAK表型的thibiofemoral差距测量的变化.
检查手术前骨关节间隙与算术膝脚角 (aHKA) 和关节直线斜率 (JLO) 之间的关系.

主要方法:

通过CT扫描和分心X线图,对433个膝盖进行了回顾性分析.
为了获得解剖学测量 (aHKA,JLO),创建了3D骨模型.
骨细胞校正算法用于计算延伸和曲的中间和侧面关节间隙;ANOVA用于比较CPAK组.

主要成果:

在CPAK组I/III和II/III之间发现了关节间隙的统计学上显著的,尽管很小的差异.
在aHKA和关节间隙之间观察到较弱的相关性 (r ≤ ≈0.32 ),而对于JLO (r ≤ ≈0.15 ) 则更弱.
多变量回归解释了aHKA (10.2%) 和JLO (1.4%) 的最小差异.

结论:

在TKA.中,CPAK对手术前的骨关节缺口具有有限的预测价值.
直接评估关节缺口对于有效的手术规划至关重要.
未来的研究应该将关节间隙测量与骨形态进行整合,以实现个性化的TKA.

Functional Classification of Joints

Functional Classification of Joints

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

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 Classification of Joints

Structural Classification of Joints

Joints, also known as articulations, are classified based on their structural characteristics, i.e., based on whether the articulating surfaces of the adjacent bones are directly connected by fibrous connective tissue or cartilage, or whether the articulating surfaces contact each other within a fluid-filled joint cavity. These differences serve to divide the joints of the body into three structural classifications.
A fibrous joint is where the adjacent bones are united by fibrous connective...
