概括
整膝关节整形整合正在从机械整合 (MA) 转向像动力整合 (KA) 这样的个性化策略,以改善患者满意度和功能结果. 需要进一步的研究来标准化技术并比较长期生存率.
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
- 医疗器械技术 医疗器械技术
背景情况:
- 机械对齐 (MA) 是全膝关节整形术 (TKA) 的传统标准,旨在实现肢体中性对齐.
- 尽管MA的生存率已被证明,但由于未解决的宪法四肢变异和软组织不平衡,患者的不满仍然很高 (高达20%).
- 这促使开发了替代的,针对患者的特定调整哲学.
研究的目的:
- 审查TKA中不断发展的对齐策略,包括MA,动力对齐 (KA),受限制的KA (rKA),反向KA (iKA),调整的MA (aMA) 和功能对齐 (FA).
- 阐明这些对齐技术的基本原理.
- 呈现和分析每个策略的可用临床结果数据.
主要方法:
- 关于TKA对齐技术的当前文献的综述.
- 检查了MA,KA,rKA,iKA,aMA和FA背后的原则.
- 对与不同对齐方法相关的临床结果和生存率数据的分析.
主要成果:
- 与MA相比,KA及其衍生物 (rKA,iKA) 旨在复制本地关节形态,可能减少软组织释放并改善功能.
- 在极端情况下,rKA和iKA结合了边界,以减轻不稳定的风险.
- 功能调整 (FA),利用机器人辅助和实时平衡,显示出个性化结果的希望,尽管建议对某些调整的MA (aMA) 技术进行谨慎,可能会增加修订风险.
结论:
- TKA调整哲学已经发展到超越传统的MA.患者特定的方法.
- 卡和其变体显示出有希望的中长期结果和可比的生存率.
- 标准化命名法 (特别是FA) 和进行高质量的比较试验至关重要. 未来的方向包括人工智能集成,以实现个性化的对齐改进,而不会影响生存.

Knee Joint
3.4K
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...

Development of the Limb Synovial Joints
2.5K
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
