概括
高骨切除术 (HTO) 在骨关节炎患者中有效改善膝盖对齐和行走功能. 非手术治疗没有改善,但在HTO后,一些运动功能偏差可能会持续存在.
科学领域:
- 整形外科手术 整形外科手术
- 生物力学 生物力学
- 膝关节骨关节炎研究研究
背景情况:
- 中间膝关节骨关节炎和肌不整齐明显损害了运动功能.
- 非手术治疗往往只能为这些情况提供有限的改善.
- 高骨切除术 (HTO) 是纠正膝关节对齐的一种手术选择.
研究的目的:
- 评估高骨切除术 (HTO) 对步态参数,运动学和运动学的影响.
- 为了比较HTO结局与非手术保守治疗在患有中枢膝关节骨关节炎和位不整的患者.
- 评估在行走,爬楼梯和下降期间的功能恢复.
主要方法:
- 一项前性随机病例对照研究,涉及49名患有膝关节中部关节炎和位错位的患者.
- 患者被随机分配到接受开式HTO (外科组,n=25) 或接受保守治疗 (保守组,n=24).
- 在基线和随访时进行了行走分析和放射性评估,对20名健康受试者进行了对照.
主要成果:
- HTO显著纠正了腿角,使其恢复到与健康对照组相似的水平 (8.3°至0.9°,p < 0.001).
- 恢复了膝盖和脚 adduction,在运动任务期间关节时刻显著改善 (p <0.05).
- 保守派组没有表现出功能上的改善;一些残留的运动偏差在HTO后仍然存在,行走速度/步伐长度没有显著变化.
结论:
- 高骨切除术有效地恢复膝盖对齐,并改善中枢膝关节骨关节炎患者的主要运动功能参数.
- 非手术保守治疗没有显著改善研究的参数.
- 在HTO后持续的运动功能偏差表明,一些生物力学适应可能会在手术后继续存在.

Bones of the Lower Limb: Tibia and Fibula
8.9K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

Knee Joint
3.1K
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...
