膝盖位错位显著增加了对中间侧带重建 (MCLR) 的力. 考虑使用MCLR进行骨切除术,以防止形形≥5°,以防止移植失败.
科学领域:
- 整形外科手术 整形外科手术
- 生物力学 生物力学
- 运动医学运动医学
背景情况:
- 中间附带带 (MCL) 损伤通常需要重建 (MCLR).
- 膝盖位对齐可能会影响MCLR的生物力学完整性.
研究的目的:
- 量化作用于单束MCLR的力量,与不同程度的膝盖关节对齐有关.
- 在动态负载条件下评估形变形对MCLR的影响.
主要方法:
- 八个人类尸体的膝盖经历了动态的瓦尔古斯负荷.
- 使用腿筋自移植进行了单捆MCLR.
- 中间开口骨切除术逐渐引入0°至10°的,在不同的曲角度测量MCLR力.
主要成果:
- 在所有测试的膝盖曲角度 (p < 0.05) 上,增加的状错位显著增加了对MCLR的力.
- 在 5° valgus 处,MCLR 力量在 16.2 N 到 18.5 N 之间.
- 在10° valgus,MCLR力增加到29.4 N至40.0 N的范围内.
结论:
- 形膝关节不整齐大大增加了重建的中间附带带的压力.
- 对于具有≥5°形变形的慢性中部不稳定性,建议与MCLR同时进行骨质切除,以增强移植保护并降低失败率.
