概括
在全膝关节整形术 (TKA) 中,放置在3°或更大的关节对齐的部部件显示出与中性机械对齐 (nMA) 相似的5年生存率. 瓦鲁斯对齐导致更少的修订和干预硬度.
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
- 关节塑造研究 关节塑造研究
背景情况:
- 在全膝关节整形手术 (TKA) 中,部部部位的变位对齐是有争议的,因为人们担心松和修改率.
- 这项研究通过比较 varus 与中性机械对齐 (nMA) 对部件的结果来解决这一争议.
研究的目的:
- 在初级TKA中,将位于3°或更大Varus对齐的部部件的5年生存时间与nMA进行比较.
- 评估两个对齐组之间的并发症,修订和患者报告的结果.
主要方法:
- 530名接受初级TKA的患者进行了回顾性匹配队列研究.
- 265名患有状部件对齐 (机器人辅助) 的患者与265名患有nMA (手动仪器) 的患者匹配.
- 最少5年的随访,分析生存率,并发症,修订和患者报告的结果.
主要成果:
- 在5年内,所有原因的生存率为Varus对齐的98%和nMA的96% (P=0.12).
- 在瓦鲁斯组中没有发生无菌松动;修订量明显较低 (5对14,P=0.02).
- 对硬度的干预在瓦鲁斯组 (3对14,P=0.003) 中明显较小.
结论:
- 在初级TKA中,在有意的小腿部部部件变量对齐和nMA之间观察到类似的中期5年生存率.
- 恢复本地斜关节线和平衡的间隙,并调整关节,证明5年后98%的存活率.

Bones of the Lower Limb: Femur and Patella
2.1K
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

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...
