概括
一个高算术-膝盖-脚角 (aHKA) 大于180°是一个风险因素,为valgus不对齐后移动轴承单膝关节整形手术 (UKA). 为了减轻这种风险,外科医生应对手术前aHKA超过180°的患者保持谨慎.
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
- 放射学 放射学是一门学科.
背景情况:
- 瓦尔古斯位不整是膝关节骨关节炎进展的常见原因,在移动轴承后的侧膝关节隔间单隔膝关节关节整形术 (UKA) 后.
- 数学-膝-脚角 (aHKA),是膝盖冠状平面对齐 (CPAK) 分类的一部分,可以表明关节炎膝盖的宪法对齐.
研究的目的:
- 为了研究算术-膝-脚角 (aHKA) 和随着移动轴承UKA的出现的错位的发生之间的关系.
主要方法:
- 在2019年1月至2022年8月期间接受UKA的200个膝盖的回顾性分析.
- 放射测量包括手术前和手术后的关节 - 膝盖 - 脚角 (HKA),机械近接角 (MPTA) 和机械侧向远距离股骨角 (LDFA).
- 患者被分为 (术后HKA> 180°) 和非 (术后HKA ≤ 180°) 组. 统计分析包括斯皮尔曼相关性,曼-惠特尼U测试,奇平方测试,费舍尔的精确测试和多重物流回归.
主要成果:
- 在200个膝盖中,28个位于团组,172个位于非团组.
- 在aHKA和术后HKA之间发现了正相关性 (r=0.693,p<0.001).
- 多重后勤回归确定了手术前的aHKA> 180°作为术后错位的显著风险因素 (OR=5.899,p=0.028).
结论:
- 在移动轴承UKA中,aHKA与手术后对齐有显著的相关性.
- 手术前的aHKA超过180°,增加了手术后 valgus不对齐的风险.
- 在手术前aHKA> 180°的患者中,手机轴承UKA应谨慎进行.

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...
