概括

没有骨关节炎 (OA) 的膝盖的结构损伤很常见,特别是在骨骨关节 (PF) 关节. 磁共振成像 (MRI) 在六年内揭示了软骨,骨髓病变和脑膜的显著变化,而不考虑OA危险因素.

科学领域:

整形外科和运动医学
放射学和成像学放射学和成像学
类风湿病学类风湿病学

背景情况:

骨关节炎 (OA) 是一种退行性关节疾病,影响着全球数百万人.
早期发现和理解结构变化对于OA管理至关重要.
使用磁共振成像 (MRI) 的纵向研究为膝关节退化提供了洞察力.

研究的目的:

在基线没有放射性OA的个体中使用MRI研究膝关节关节区间的纵向变化.
为了比较结构变化的发生率在中间与侧面的小腿骨 (TF) 和腿骨 (PF) 区.
评估关节炎风险状况对膝盖结构损伤发展的影响.

主要方法:

340名45-55岁的患者 (骨关节炎倡议) 在基线和6年随访期间接受了膝盖MRI扫描.
使用MRI骨关节炎膝盖评分系统评估MRI扫描,以评估软骨,骨,骨髓病变 (BMLs) 和阴茎损伤.
统计分析 (混合效应波桑回归) 将结构变化的风险与各组件和OA风险状况进行了比较.

主要成果:

在6年内,89%的个体出现了增加的软骨损伤,75%出现了新的或恶化的骨髓病变 (BMLs),28%出现了阴道损伤.
与侧侧骨 (TF) 关节相比,骨 (PF) 关节的软骨损伤风险最高 (RR 2.4),骨质细胞 (RR 1.3) 和骨质瘤 (BML) (RR 2.8) 风险最高.
中间TF的阴茎损伤风险高于侧面TF (RR 2.8),有风险的膝盖显示阴茎损伤风险增加 (RR 1.8).

结论:

在大多数最初被归类为Kellgren-Lawrence等级0.0的膝盖中,膝盖结构损伤的进展显著.
这些变化不论是否存在骨关节炎的危险因素都会发生,这突显了广泛的亚临床退化.
骨骨关节是膝盖早期结构变化的主要部位,面临OA风险或发展OA.

Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

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...

Imaging Studies IV: Magnetic Resonance Imaging

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...
