概括

在前交叉带重建 (ACLR) 后,膝关节关节运动显示逐渐恢复,但在旋转和曲方面存在持久异常. 量身定制的康复对于在手术后一年内优化功能结果至关重要.

科学领域:

整形外科整形外科整形外科
生物力学生物力学
运动医学运动医学

背景情况:

前十字带重建 (ACLR) 是一种常见的手术,用于恢复膝盖的稳定性.
术后康复对于功能恢复至关重要,但最佳策略需要对膝关节关节动力学有更深入的了解.
在ACLR之后,六度自由度 (6DOF) 膝盖动力学的动态变化尚未完全阐明.

研究的目的:

研究在ACLR后一年内患者的6DOF膝关节动力学的动态变化.
将动力学数据与临床分数 (IKDC,KOOS) 相关联,以评估功能恢复.
为优化术后康复策略提供证据.

主要方法:

招募了49名ACLR后患者,在3,6和12个月后进行随访,以及29名健康对照.
使用3D运动捕捉系统收集6DOF膝盖运动数据.
通过IKDC和KOOS得分评估临床功能;使用SPM1D分析动力学数据.

主要成果:

患者在ACLR后3至12个月的IKDC和KOOS得分显著改善.
膝关节动力学逐渐恢复,但仍然存在显著的异常,包括增加的加伸 (冠状),屈曲 (斜) 和内部旋转 (横向) 角度.
与对照组相比,观察到曲和旋转的运动范围减少.

结论:

在ACLR后的膝关节运动恢复是多维和动态的,在手术后的一年内持续存在异常.
恢复模式在不同的运动平面和翻译上有所不同.
建议进行个性化康复,重点关注早期的关节稳定性和以后的旋转/屈曲延伸纠正,以改善长期结果.

Knee Joint

Knee 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...

Bones of the Lower Limb: Femur and Patella

Bones of the Lower Limb: Femur and Patella

The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...
