概括

这项研究发现,ATTUNE全膝关节整形术 (TKA) 在5年内显示出稳定的固定和与PFC-Sigma TKA可比的结果. 没有证据表明部部件迁移增加,这支持人们对ATTUNE TKA.的无菌松动的担忧.

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
放射学放射学是指放射学

背景情况:

对于ATTUNE全膝关节整形术 (TKA) 存在相互矛盾的临床结果.
这项研究比较了凝固的ATTUNE和PFC-Sigma交叉式维护TKA.

研究的目的:

评估ATTUNE与PFC-Sigma TKAs的五年随访结果.
使用射频立体分析 (RSA) 分析组件迁移.
评估临床结果,患者报告的结果措施 (PROM) 和放射性结果.

主要方法:

一个单盲随机受控试验 (RCT) 包括74个初级TKA.
放射立体分析 (RSA) 和PROM在多个时间点收集到60个月.
放射性线条 (RLLs) 被测量在6周,12个月和60个月.

主要成果:

五年后,ATTUNE (0.96毫米) 的大腿部部部件迁移 (MTPM) 比PFC-Sigma (1.37毫米) 低 (p < 0.001).
在ATTUNE (1.12毫米) 和PFC-Sigma (1.25毫米) (p = 0.438) 之间,部成分MTPM是可比的.
在5年后,ATTUNE (20%) 与PFC-Sigma (3%) 的中部部RLL更为普遍,但没有进展.

结论:

ATTUNE TKA表现出稳定的固定,部和部部件的迁移相当于PFC-Sigma在5年.
没有证据表明小腿骨部部件迁移增加,这表明ATTUNE无菌松的风险没有增加.
预计ATTUNE TKA的长期性能将与已建立的PFC-Sigma系统相提并论.

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...

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...
