概括
修复性全膝关节整形术 (rTKA) 可能导致下骨 (PB) 和伪PB (PPB). 感染是PB的关键风险因素,影响手术后的运动范围.
科学领域:
- 整形外科手术 整形外科手术
- 生物医学工程 生物医学工程
- 膝盖关节整形手术 膝盖关节整形手术
背景情况:
- 关节高度异常,包括真关节下部 (PB) 和伪PB (PPB),在修复全膝关节整形术 (rTKA) 中存在重大挑战.
- PB是由于骨肌缩短而产生的,而PPB的特征是由于关节直线升高而导致远端骨位移.
- 了解这些疾病的发病率和风险因素对于优化rtka结果至关重要.
研究的目的:
- 为了调查修复膝关节全关节整形术 (rTKA) 后的低膝关节 (PB) 和伪PB (PPB) 的发生率.
- 在rtka患者队列中确定与PB和PPB发展相关的关键风险因素.
- 分析PB和PPB对手术后运动范围的影响,与正常的骨高度相比.
主要方法:
- 进行了由一名外科医生进行的375例rTKA病例的回顾性分析.
- 使用Insall-Salvati和Blackburne-Peel比率来确定PB和PPB,评估了皮带高度.
- 用单变量和多变量回归分析来确定PB和PPB的风险因素.
主要成果:
- 在被研究的RTKA人群中,PB的发病率为24%,PPB为14%.
- 对感染进行了修订的患者表现出明显更高的可能性 (9倍) 发展PB (P = .002).
- 手术前的皮带高度,之前的手术数量和对感染的修复被确定为PB的显著风险因素.
结论:
- 识别风险因素,如手术前骨高度,手术前史和感染,作为检查的指示,对于管理PB和PPB至关重要.
- 这些发现可以指导外科医生解决RTKA.rTKA.的骨高度并发症.
- PB和PPB与运动范围的最小变化有关,与正常骨高度患者的改善不同.

Bones of the Lower Limb: Femur and Patella
4.7K
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...

Knee Joint
3.0K
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...
