What causes fluid to leak from joints?

Summary. Excess fluid around a joint—called an effusion—affects larger joints, such as the knee. A joint effusion can occur as a result of injury, infection, or different types of arthritis. In many cases, fluid can be drained, and steps taken to address the cause (such as antibiotics for an infection).

What does infected joint fluid look like?

Normal synovial fluid is clear and colorless or straw-colored. Abnormal fluid may look cloudy, opaque, and/or differently colored. For example, cloudy fluid may indicate an infection, and pink or reddish fluid may indicate the presence of blood.

Can synovial fluid get infected?

Septic arthritis is an infection in the joint fluid (synovial fluid) and joint tissues. It occurs more often in children than in adults. The infection usually reaches the joints through the bloodstream. In some cases, joints may become infected because of an injection, surgery, or injury.

What does a yellow orange color of joint fluid indicate?

Normal joint fluid is clear and colorless. Red or red-tinged fluid indicates hemorrhage in the joint associated with trauma or inflammation or hemorrhage that has occurred during the collection process. Xanthochromia is a yellow-orange discoloration that indicates prior hemorrhage and hemoglobin breakdown.

What color should fluid drained from knee be?

Normal synovial fluid is straw-colored, clear, and slightly sticky or stringy. Abnormal synovial fluid may be cloudy and thicker or thinner than normal fluid. Cloudiness could mean there are crystals, excess white blood cells, or microorganisms in the fluid.

What does it mean when you have purulent drainage in your wound?

This type of drainage often indicates infection of the wound. The reason that purulent drainage is off-color and thick relates to pathogenic microorganisms and dying bacteria, as well as inflammatory and white cells invading the infected area.

What’s the difference between pus and purulent exudate?

Drainage is not the same as purulent exudate, the medical term for pus. In fact, a wide variety of types of drainage are often normal, and are not pus, but are misidentified as pus. Actual pus is drainage that is full of dead white blood cells that rush to the site to help the body fight the infection.

Why do I have fluid coming out of my wound?

You may notice clear fluid or fluid with a pink or yellow tint draining from the broken skin or the surgical site if you had an operation. These are part of the healing process that your body deploys when you get injured. The fluids carry proteins, sugars, and white blood cells that are critical to repairing the injury.

What are the diagnostic criteria for a chyle leak?

The diagnosis of a chyle leak is often subjective, and diagnostic criteria may vary. To confirm that a fluid is chylous, the lipid content should be greater than that of plasma and the protein should be more than half of that of plasma (1).
