概括

这项研究比较了两种修复全膝盖植入物,发现两者都能恢复关节直线高度. 远距离增大可以防止用状体植入物提高关节线. 在测量方面,AP射线图是最可靠的.

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

背景情况:

修复全膝关节置换 (TKR) 旨在恢复关节功能和稳定性.
准确恢复关节直线高度对于最佳的TKR结果至关重要.
不同的植入物设计可能会影响关节线恢复.

研究的目的:

为了比较两种修订TKR植入物设计 (状和旋转链) 对关节直线高度的影响.
评估远端增强在修改TKR期间管理关节直线高度的作用.

主要方法:

追溯分析了19个共存器 (Zimmer NexGen LCCK) 和40个旋转链 (LINK-Endo RHK) 修改TKR的案例.
使用四种经过验证的放射学方法测量修改前和后的关节线和骨高度.
使用配对和不配对的学生t测试进行统计比较,显著性设置为p < 0.05.

主要成果:

在15/19个NexGen病例中使用了远端增生器,但在LINK-Endo RHK组中没有使用过.
两种植入物系统都没有显示出相对于骨的关节线上升的倾向.
尼克斯基因组显示腿部脱,而旋转轮组显示腿部接近关节线.
在评估关节直线高度方面,前后 (AP) 放射图比侧面放射图更可靠.

结论:

状和旋转链修复TKR系统都能有效地恢复关节线高度.
距离增大可以帮助避免在尾类型修订TKR中关节线的升高.
在修改TKR中,AP放射是最可靠的方法来准确评估关节直线高度.

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...

Development of the Limb Synovial Joints

Development of the Limb Synovial Joints

Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...

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...
