概括
这项研究引入了一种全膝关节整形术 (TKA) 的新型股骨切割系统,该系统利用股骨状体作为地标,提高了手术的准确性. 新系统显示了与传统方法相比的可比性,手术时间缩短.
科学领域:
- 整形外科 整形外科 整形外科
- 手术创新 在外科创新.
- 生物机械工程 生物机械工程
背景情况:
- 传统的膝关节关节整形术 (TKA) 的骨髓内指南可能会导致由于进入点的位置不正确而导致不对齐.
- 已经开发出一种新的股骨切割系统,该系统引用了距离和后股骨,独立于股骨道.
- 该系统旨在提高腿部部部件在TKA中的位置的准确性.
研究的目的:
- 为了评估TKA的新股骨切割系统的临床结果.
- 通过使用新的状体参考系统来评估股骨对齐的准确性.
- 为了比较新系统与传统方法之间的手术时间和血液损失.
主要方法:
- 一系列的75个连续的膝盖接受了TKA被纳入.
- 手术后的冠状和角对齐 (α,gamma,部-膝盖-脚角) 在三个月后被测量.
- 所有患者的手术时间和手术内流血量都被记录下来.
主要成果:
- 动力对齐 (KA) TKA (n=60) 和机械对齐 (MA) TKA (n=15) 两组都实现了正常的冠状和斜面对齐.
- 在KA-TKA和MA-TKA组 (213.11 ± 52.73毫升) 之间,手术期间的失血是相似的.
- 与MA-TKA (49.34 ± 4.56 分钟) 相比,KA-TKA (41.11 ± 3.77 分钟) 的手术时间显著缩短 (P < 0.001).
结论:
- 新的股骨切割系统有效地使用远端和后端的股骨形作为地标,用于在TKA中准确切割远端股骨.

Bones of the Lower Limb: Femur and Patella
2.5K
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

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...
