概括
较高的手术前膝盖屈曲和较大的股骨切除与膝盖置换手术后更糟糕的结果有关. 了解这些因素可以帮助改善经过十字关节保持全膝关节整形术 (CR-TKA) 的患者的结果.
科学领域:
- 整形外科手术 整形外科手术
- 生物力学 生物力学
- 关节塑造研究 关节塑造研究
背景情况:
- 膝盖曲运动范围 (ROM) 是膝盖全关节整形术 (TKA) 后的关键结果指标.
- 曲ROM的恶化可以显著影响患者的功能和满意度.
- 识别ROM损失的预测因素对于优化CR-TKA手术技术和患者选择至关重要.
研究的目的:
- 为了确定与膝盖曲运动范围 (ROM) 显著下降相关的手术前和手术后的风险因素,在十字关节保持全膝关节整形术 (CR-TKA) 后.
主要方法:
- 对129名接受CR-TKA治疗的患者进行了回顾性比较研究,随访2年.
- 根据临床显著下降 (≥9°) 的屈曲ROM,将患者分类为组.
- 后勤回归和ROC曲线分析用于识别相关因素及其切线值.
主要成果:
- 更大的手术前曲ROM (>130.0°),更大的远端中间股骨切除 (DMFR) (>7.5mm),和下部前后翻译在30°曲1年术后 (<5.1mm) 独立地与≥9°的ROM减少有关.
- 这些因素是使用后勤回归和ROC曲线分析来确定的.
结论:
- 术前曲ROM,DMFR和1年的术后前后翻译是CR-TKA后2年曲ROM恶化的显著预测因素.
- 这些发现可以指导外科医生管理患者的期望和手术规划,以改善曲ROM的结果.

01:23Knee 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...

01:10Ankle 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...
