概括
在全膝关节整形术中,功能对齐 (FA) 显示了与机械对齐 (MA) 相似的两年结果,但需要较少的软组织释放. FA可能会使特定的患者群体受益,这些患者具有独特的手术前调整.
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
- 医疗技术 医疗技术 医学技术
背景情况:
- 机械对齐 (MA) 是全膝关节整形术 (TKA) 的标准,但患者的不满仍然存在.
- 功能性对齐 (FA) 通过将动力对齐 (KA) 与骨平衡相结合提供了一个替代方案,旨在恢复原生关节线和软组织平衡.
- 在TKA中,FA与MA的比较数据有限.
研究的目的:
- 在TKA中比较机器人辅助MA和FA之间的患者报告结果和手术指标.
- 评估FA在改善功能结果和TKA后患者满意度方面的有效性.
- 确定潜在的患者亚组,这些亚组可能会从FA中获益更多.
主要方法:
- 一项前性随机对照试验,涉及MA组的121名患者和FA组的123名患者.
- 机器人辅助的TKA使用MA (垂直于机械轴的组件) 或FA (与调整相匹配的本地解剖学) 进行.
- 主要结局是被遗忘的联合评分 (FJS);次要结局包括KOOS,OKS,EQ-5D,以及使用混合模型ANOVA分析的临床措施.
主要成果:
- 在2年后,FJS在MA和FA之间是可比的 (P=0.10).
- 对于FA,软组织释放的次数要少得多 (16%与65%,P<0.001).
- 患有FA的患者报告了更高的KOOS症状 (P=0.01) 和生活质量 (P=0.03) 评分,更愿意推该程序 (94%对82%,P<0.01).
- 患有手术前冠状平面对齐膝盖I型的患者表现出优异的FJS和KOOS-QoL与FA.
结论:
- 在TKA中的FA导致了与MA相似的两年结果,但软组织释放量减少.
- 通过手术前对齐识别的特定患者亚组,FA可能会提供更好的结果.
- FA代表了MA的可行的替代品,可能会提高患者的满意度和功能恢复.

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...
