Extra-Articular Effusion is a medical condition involving the accumulation of fluid outside a joint. Understanding this condition is crucial for timely diagnosis and effective management. This guide provides detailed information about Extra-Articular Effusion, including its definitions, causes, symptoms, diagnostic methods, treatments, and more
Extra-Articular Effusion refers to the buildup of fluid in areas surrounding a joint, but not within the joint itself. Unlike joint effusion, which occurs inside the joint capsule, extra-articular effusion affects the tissues and structures adjacent to the joint, such as bursae, tendons, and ligaments.
Pathophysiology
Structure
Understanding the structure around a joint helps explain how extra-articular effusion occurs. Joints are surrounded by various structures:
- Bursae: Small fluid-filled sacs that reduce friction between tissues.
- Tendons: Connect muscles to bones.
- Ligaments: Connect bones to other bones, providing stability.
When inflammation or injury affects these structures, fluid can accumulate outside the joint capsule, leading to extra-articular effusion.
Blood Supply
Blood vessels supply nutrients and oxygen to joint tissues. Inflammation can increase blood flow to these areas, leading to fluid leakage into surrounding tissues.
Nerve Supply
Nerves around the joint can become irritated due to inflammation or fluid buildup, causing pain and discomfort.
Types of Extra-Articular Effusion
- Bursal Effusion: Fluid accumulation in bursae.
- Tendinous Effusion: Fluid around tendons.
- Ligamentous Effusion: Fluid around ligaments.
- Subcutaneous Effusion: Fluid under the skin near the joint.

Here are 20 potential causes of Extra-Articular Effusion:
- Trauma or Injury: Sprains, strains, or fractures.
