概括
一个新的分类,基于限制边界的膝盖冠状平面对齐 (Rb-CPAK),更好地识别需要在全膝关节整形术中进行限制的膝盖. 关节线斜率本身不足以确定限制需求.
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
- 医疗成像医学成像
背景情况:
- 膝盖冠状平面对齐 (CPAK) 分类有助于理解腿部对齐和关节线斜率 (JLO) 的膝盖表型.
- 现有的CPAK边界在适应受限动力调整全膝关节整形术 (rKA-TKA) 时有所不同.
- 需要对CPAK边界进行重新评估,以便rKA-TKA定义基于限制边界的CPAK (Rb-CPAK).
研究的目的:
- 为rKA-TKA提出和验证修改后的CPAK分类 (Rb-CPAK).
- 评估Rb-CPAK在识别需要手术限制的膝盖方面的有效性.
- 评估JLO与rKA-TKA限制的必要性之间的相关性.
主要方法:
- 分析了2020年5月至2022年3月期间接受rKA的95名患者的143个膝盖.
- 定义了Rb-CPAK标准:aHKA (6° varus到3° valgus),MPTA (0°到6° varus),LDFA (0°到5° valgus) 和JLO (169°到180°).这些标准包括:aHKA (6° varus到3° valgus),MPTA (0°到6° varus),LDFA (0°到5° valgus) 和JLO (169°到180°).
- 术前和术后的对齐被分类使用原始CPAK和Rb-CPAK.
主要成果:
- 在原始CPAK和Rb-CPAK之间的术前和术后分布中观察到显著差异 (p < 0.0001).
- 手术后的Rb-CPAK主要导致中性AHKA (116/143膝盖),减少MPTA变量和稳定的LDFA.
- 78个中性JLO的膝盖需要MPTA或LDFA纠正;64%的中性JLO病例在术后属于MPTA/LDFA范围.
结论:
- 在rKA-TKA.中,Rb-CPAK修改有效地识别了需要限制的膝盖.
- 根据Rb-CPAK标准,限制协议被适当执行.
- JLO不是限制的可靠指标;需要对个别的LDFA和MPTA进行评估.

Functional Classification of Joints
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 group...
