概括

在严重的膝关节骨关节炎 (OA) 中,骨关节内脂肪 (IFP) 刚度,而不是尺寸,更高,并且与膝关节症状恶化相关. 这表明IFP度可能是管理膝关节OA的目标.

科学领域:

整形外科整形外科整形外科
放射学放射学是一门学科.
生物医学工程生物医学工程

背景情况:

膝关节骨关节炎 (OA) 是一种导致疼痛和残疾的退行性关节疾病.
膝盖内脂肪 (IFP) 是一个关节内结构,可能在膝盖骨关节炎的发病过程中发挥作用.
了解IFP与OA严重程度相关的特性对于开发新的管理策略至关重要.

研究的目的:

为了研究皮下脂肪 (IFP) 刚性和大小以及膝关节骨关节炎 (OA) 严重程度之间的关联.
确定IFP特性与OA患者膝盖症状之间的关系.

主要方法:

超声波被用来测量IFP剪切模量 (刚度) 和厚度 (大小) 在93名参与者 (66名膝盖OA,27名对照).
参与者被分为控制,轻度OA (KL等级2) 和严重OA (KL等级3-4) 组.
用膝关节社会得分 (KSS) 评估膝关节症状,回归分析探讨了IFP属性和症状之间的关联.

主要成果:

与对照组相比,在严重的OA组中,infrapatellar脂肪的剪切模块显著更高.
在任何组之间都没有观察到IFP厚度的显著差异.
更高的IFP度与更严重的膝关节OA症状 (更高的KSS分数) 有很强的相关性.

结论:

在严重的膝盖骨关节炎中,皮下脂肪的刚性升高.
增加的IFP度与较大的膝盖症状严重程度有关.
IFP硬度是评估的潜在生物标志物,也是膝关节OA管理的治疗目标.

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...

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...
