概括

骨髓病变 (BMLs) 随着时间的推移,在中部开式高骨切除术 (MOWHTO) 后减少. 这种BMLs的减少与两年后患者报告的改善结果 (PROMs) 相关联,位对齐是关键因素.

科学领域:

  • 整形外科手术 整形外科手术
  • 放射学 放射学是一门学科.
  • 生物医学工程 生物医学工程

背景情况:

  • 骨髓病变 (BMLs) 在膝关节关节炎中很常见,可能会影响患者的治疗结果.
  • 中部开高骨切除术 (MOWHTO) 是一种手术程序,用于纠正膝关节骨关节炎中的位不整.
  • 了解MOWHTO后的BMLs自然史对于预测治疗成功至关重要.

研究的目的:

  • 追踪术前骨髓病变 (BMLs) 发生的连续变化,经过中部开口高骨切除术 (MOWHTO) 长达两年.
  • 为了确定手术后的BML变化是否影响患者报告的结果指标 (PROMs) 在两年后续.
  • 为了确定与MOWHTO后手术后的BML变化相关的因素.

主要方法:

  • 对从接受MOWHTO治疗膝关节骨关节炎的患者前性收集的数据进行回顾性分析.
  • 进行了手术前和手术后的3,6,18和24个月的连续MRI扫描,以评估BML程度.
  • 患者报告的结果措施 (PROMs) 在术前和术后进行了评估,并分析了临床上重要的最小差异.
  • 线性混合模型被用来分析BML和PROM随时间的推移之间的关联.
  • 评估了影响BML变化的因素.

主要成果:

  • 在80.8%的患者中存在手术前的BML.
  • 经手术后,在骨和骨中部观察到BMLs的显著下降,持续减少至24个月.
  • 很高比例的患者在整体WOMBAT和KOOS亚尺度中实现了临床重要差异的最小值.
  • 手术后的BML减少与24个月后更好的PROM显著相关.
  • 规范校正 (2°-5°) 是MOWHTO后BMLs降低的一个重要因素.

结论:

  • 手术前的骨髓病变 (BMLs) 经过中部开口高骨切除术 (MOWHTO) 显示随着时间的推移逐渐减少.
  • 在MOWHTO后BMLs的减少与两年后患者报告的改善结果 (PROMs) 有显著的相关性.
  • 实现手术后的关节对齐是MOWHTO后 BMLs 降低的一个关键因素.
