概括
在全膝关节整形术 (TKA) 后的关节结块综合征在十字形置换植入物中较少见,而不是在后部稳定设计中. 这一发现表明,植入物设计显著影响这种并发症的风险.
科学领域:

背景情况:
- 关节骨和关节骨综合征是全膝关节整形术 (TKA) 后的已知并发症.
- 这些现象的确切原因尚不清楚.
- 了解风险因素对于改善TKA后患者的治疗结果至关重要.
研究的目的:
- 为了比较两个不同的全膝关节关节整形植入体设计之间的关节块综合征的发病率.
- 为了研究植入物设计在TKA后骨块的发展中的作用.

Bones of the Lower Limb: Femur and Patella
2.0K
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
1.3K
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...
