概括
患有骨质疏松症的患者在全膝关节关节整形术 (TKA) 后有更高的修复手术风险,特别是围围假肢骨折. 这项研究强调了需要解决TKA患者的骨质疏松症,以改善结果.
科学领域:
- 整形外科手术 整形外科手术
- 骨代谢障碍 骨代谢障碍 骨代谢障碍
- 生物统计学 生物统计学
背景情况:
- 在全膝关节整形术 (TKA) 后,骨质疏松症的风险尚不清楚.
- 这项研究旨在比较手术前骨质疏松症TKA患者的修复手术风险.
研究的目的:
- 评估骨质疏松症患者TKA后修复手术的5年累积风险.
- 为了确定与骨质疏松症相关的修复手术的具体原因.
主要方法:
- 对国家行政索赔数据库 (2010-2021) 的分析,包括418,054名初级TKA患者.
- 检查了所有原因的5年复查发生率,周围假肢骨折 (PPF),无菌松动和周围假肢关节感染 (PJI).
- 多变量Cox比例危险模型用于评估风险,报告危险比率 (HRs) 和95%置信区间 (CI).
主要成果:
- 患有骨质疏松症的患者具有更高的全因复查风险 (HR 1.1).
- 骨质疏松症患者的最高风险是PPF (HR 1.8),其次是PJI (HR 1.2) 和无菌松动 (HR 1.2).
- 骨质疏松症与肥胖患者中较高的PJI和无菌松动率有关.
结论:
- 在调整了混因素后,骨质疏松症显著增加了TKA后PPF修订的5年风险 (几乎是2倍).
- 在患有骨质疏松症的患者中,所有原因,无菌松动和PJI的修订风险略有增加.
- 肥胖可能会影响骨质疏松症和复查风险之间的关联;对骨质疏松症治疗的进一步研究是有必要的.

Knee Joint
1.9K
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...

Bone Disorders
3.6K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
