概括
在型关节骨关节炎中,全关节置换 (TAR) 有效地恢复了亚关节的对齐. 这种手术通过重新定位骨来改善后脚的生物力学,为患有这种疾病的患者提供了潜在的解决方案.
科学领域:
- 整形外科手术 整形外科手术
- 生物力学 生物力学
- 骨关节炎的研究研究.
背景情况:
- 瓦鲁斯脚关节性骨关节炎经常与周围关节的不稳定性有关.
- 这种不稳定性会导致异常的下关节定位.
研究的目的:

1.7K
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...

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...
