概括

在全膝关节整形术 (TKA) 中的旋转不匹配在卧卧姿势中可能被低估,影响患者的结果. 谨慎的部件放置至关重要,特别是严重的形变形,以避免站立位置的不良对齐并改善结果.

科学领域:

整形外科手术整形外科手术
生物医学工程生物医学工程
放射学放射学是一门学科.

背景情况:

组件旋转对齐对于成功的全膝关节整形术 (TKA) 是至关重要的.
在仰卧姿势中评估旋转不匹配可能不会准确地反映站立的对齐.
手术前的变形会影响手术内部件的定位.

研究的目的:

为了评估TKA组件在仰卧与站立的位置之间的旋转不匹配.
调查站立姿势轮转不匹配对患者报告结果测量 (PROM) 的影响.

主要方法:

对中枢膝关节骨关节炎的71个TKA进行了分析.
旋转不匹配的测量是使用3D到2D图像登记在仰卧和站立的X线图.
用CT扫描来验证组件对齐,并使用膝关节社会得分 (KSS 2011) 评估PROM.

主要成果:

总体而言,卧卧和站立的位置之间的旋转不匹配是相似的.
15%的患者高估了不匹配的仰卧位置,而23%的患者低估了不匹配的仰卧位置 (大不匹配的站立).
低估的不匹配与严重的手术前形变形和明显较差的PROM相关 (KSS 2011分数较低).

结论:

"低估组"在临床上具有意义,因为手术是在卧底进行的.
严重的手术前形变形需要仔细注意,以避免在站立姿势中出现扭转.
防止站立姿势的旋转不匹配是TKA后患者有利结果的关键.

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 group...

Ankle Joint

Ankle Joint

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
