背景情况:
- 膝关节关节病在严重的血友病中很普遍,由于明显的形态变化,对全膝关节整形术 (TKA) 提出了独特的挑战.
- 了解这些形态差异对于优化血友病患者手术结果至关重要.
研究的目的:
- 为了比较血友膝盖与非血友骨关节炎 (OA) 膝盖的手术内形态特征.
- 为血友病患者提供基于证据的TKA外科手术技术建议.
主要方法:
- 对16名接受TKA的血友病患者进行了形态分析,与18名性别匹配的OA对照进行了比较.
- 在手术期间的测量包括股骨和骨尺寸 (中侧宽度,前后长度) 和间口大小.
- 手术技术的修改和部件尺寸与形态发现相关.
主要成果:
- 与OA膝关节相比,血友膝关节的股骨中侧宽度显著增加,面积比率更高.
- 在血友性膝盖中,介质间口的尺寸显著更大.
- 在血友性膝盖中,基于后状骨轴的外部旋转更大,需要75%的部件大小变化,在68.75%的病例中改变了股骨旋转.
结论:

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...
