概括
关节或膝关节置换手术后的长期体重指数 (BMI) 通常不会显著变化. 虽然许多患者体重波动,但关节整形并不是整体BMI改善的可靠方法.
科学领域:
- 骨科手术
- 代谢健康
- 生物统计学
背景情况:
- 接受关节整形手术 (THA) 和膝关节整形手术 (TKA) 的患者通常的目标是减肥.
- 这些手术后体质指数 (BMI) 的长期变化在很大程度上是未知的.
研究的目的:
- 在初级THA和TKA后的2,5年和10年的BMI变化分析.
- 确定这些关节置换手术后的BMI变化的预测因素.
主要方法:
- 对763名骨关节炎患者 (310名THA,453名TKA) 的回顾性分析,这些患者接受了初级关节整形 (2001-2011).
- 在手术和2,5,10年后收集的BMI数据.
- 用于BMI变化分析和预测因子识别的重复测量ANOVA和多项逻辑回归.
主要成果:
- 在THA和TKA后的2年和5年,平均BMI略有增加,但在10年后恢复到基线.
- 在10年后,27% - 30%的患者的BMI下降了> 5%,而30-32%的BMI增加了> 5%.
- 女性预测THA后BMI增加> 5%,年龄较大预测TKA后降低.
结论:
- 在大多数患者中,关节整形术并没有显著改善整体BMI.
- 在手术后10年,个体BMI的变化可能是显著的 (> 5%).
- 性别和年龄等人口因素可以预测关节置换后临床上显著的体重变化.

01:09Changes in the Appendicular Skeleton with Age
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

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...
