概括

膝关节整形术 (TKA) 改善了步态和日常生活活动 (ADLs),可能会预防跌倒. 然而,逆侧膝关节骨关节炎 (KOA) 可能会对TKA后的步态改善产生负面影响.

科学领域:

整形外科整形外科整形外科
生物力学生物力学
老年学是一门学科.

背景情况:

膝关节关节炎 (KOA) 严重损害了步态和平衡,增加了跌倒的风险,并阻碍了日常活动.
膝关节整形术 (TKA) 是一种常见的手术,用于缓解KOA症状并改善功能.
反侧膝关节状况对TKA后步态恢复的影响仍未得到充分研究.

研究的目的:

为了研究TKA后的步态变化,与对侧膝盖的KOA严重程度相关.
评估TKA对步态对称性,均性和步数的影响.
检查TKA在防摔方面的潜力,考虑到对侧膝盖状况.

主要方法:

在TKA后1年对53名患者进行前性研究.
使用智能手机软件测量的步行参数 (对称性,均性,步骤).
使用重复测量ANOVA进行统计分析;植入物类型 (CR与PS) 和逆侧膝关节状况之间的比较.

主要成果:

与手术前和手术后3周的测量相比,TKA后1年行走参数显著改善 (p < 0.05).
十字状保持 (CR) 和后部稳定 (PS) 植入物之间,步态对称性和均性的改善类似.
术前对称性和均性随着对手KOA等级的增加而下降,即使在TKA后;步数不受影响.

结论:

TKA增强膝盖功能,步态模式和日常生活活动,有助于预防跌倒.
逆侧膝关节骨关节炎甚至在TKA后也会对步态参数产生负面影响.
非手术膝盖的状况是TKA在改善步态和降低跌倒风险方面的整体成功的关键因素.

Fractures: Bone Repair

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

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...

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...
