概括
这一元分析没有发现动力对齐对全膝关节关节整形术 (TKA) 的机械对齐有临床重要的益处. 患者的结果和运动范围没有显著改善,这表明动力学对齐还不应该被广泛采用.
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
- 临床结果研究研究的临床结果.
背景情况:
- 关于动力对齐与机械对齐在全膝关节整形术 (TKA) 中的优越性存在争论.
- 虽然一些评论表明动力学对齐可能是首选的,但观察到的差异可能不会转化为患者感知到的结果或耐久性的改善.
- 最小临床重要差异 (MCID) 对于评估患者观察到的结果得分变化的意义至关重要.
研究的目的:
- 为了确定TKA中的动力学对齐是否与机械对齐相比,提高了临床上重要的边际,改善了患者报告的结果措施 (PROMs).
- 为了评估TKA中的动力调整是否与机械调整相比,改善了临床上重要的运动范围 (ROM).
主要方法:
- 随机对照试验 (RCT) 的系统审查和元分析,比较动力与机械对齐TKA,通过Medline和Embase数据库确定.
- 包括12个RCT与1033名患者 (平均年龄68岁);使用Cochrane风险偏差工具评估偏差风险.
- 提取和聚合PROM (牛津膝关节分数[OKS],遗忘关节分数[FJS],WOMAC,EuroQol 5域) 和ROM的数据,在可能的情况下将分数转换为通用尺度.
主要成果:
- 对于功能分数 (例如,OKS,WOMAC) 的动力和机械对齐TKA之间没有发现临床重要差异,平均差异不超过MCID.
- 在两个对齐组之间没有观察到FJS,EuroQol5域VAS得分或ROM (延伸和曲) 的显著差异.
- 观察到的结果的统计差异通常太小,患者无法注意到或认为具有临床意义.
结论:
- 这一元分析表明,基于目前的RCT证据,动力学对齐对TKA的机械对齐没有临床上重要的益处.
- 鉴于缺乏患者可感知的优势,以及与动力学对齐相关的额外成本,时间和潜在风险,不建议广泛采用.
- 需要进一步的精心设计的RCT来证明动力学对齐的明显优势,才能在临床实践中得到广泛采用.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

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...
