- 整形外科手术 整形外科手术
- 生物机械工程 生物机械工程
背景情况:
- 机械整齐全膝关节整形术 (MA TKA) 经常提高关节线,以解决固定曲收缩 (FFC).
- 不受限制的动力对齐TKA (KA TKA) 使用基于口径的技术,它本质上不提高关节线.
研究的目的:
- 评估不受限制的KA TKA在恢复FFC患者的完全延伸方面的有效性.
- 为了确定KA TKA是否可以在不增加远端股骨切除的情况下实现这一目标.
- 分析骨切除和部部件定位在实现延伸中的作用.
主要方法:
- 对机器人辅助的十字形保持不受限制的KA TKA (n=48) 的回顾性研究.
- 对手术前FFC≥5° (研究组) 与FFC<5° (对照组) 的患者进行比较.

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
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...
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.
