概括
与那些单独患有KOA的人相比,患有腿骨转移截肢和膝关节关节炎 (KOA) 的人在完整的肢体中表现出更大的四头肌强度. 这表明截肢者可能需要增加力量来维持日常功能并保护他们的膝关节.
科学领域:
- 生物力学 生物力学
- 整形外科 整形外科 整形外科
- 康复科学 康复科学 康复科学
背景情况:
- 下肢截肢增加了对侧肢膝关节骨关节炎 (KOA) 的风险.
- 有限的研究存在于KOA和截肢患者的力量特征.
研究的目的:
- 为了比较KOA患者的下肢强度,有或没有单边转骨截肢 (TF).
主要方法:
- 一项描述性实验室研究比较了7名单边TF截肢和KOA的参与者与9名KOA (对照) 的参与者.
- 用KOA对受影响的肢体进行了强度测试,并分析了质量正常化的强度变量.
- 膝盖损伤和骨关节炎结局得分 (KOOS) 用于测量主观功能.
主要成果:
- 与对照组相比,移截肢组的平均和峰值异动力学四头体扭矩和平均异动力学四头体功率显著增加.
- 两组之间在同度膝盖延伸器或曲器强度上没有发现显著差异.
- 对照组在KOOS总和症状得分上报告主观功能明显差.
结论:
- 与KOA的对照人群相比,患有TF截肢和KOA的个人在完整的肢体中表现出优越的异动力膝盖延伸器强度.
- 截肢者可能需要更高的异动力学强度来进行日常活动,这可能表明需要更高的强度值来防止膝关节软骨退化.

01:16Bones of the Lower Limb: Femur and Patella
4.8K
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...

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...
