Joint effusion

Joint Effusion

Joint effusion, pronounced as /ˈdʒɔɪnt ɪˈfjuːʒən/, is a medical condition characterized by the accumulation of excess fluid in or around a joint. The term is derived from the Latin word 'effusio', which means 'a pouring out'.

Causes

Joint effusion is often caused by inflammation or injury to the joint. Other common causes include arthritis, gout, infection, and tumors. In some cases, joint effusion may also be caused by bleeding into the joint space, a condition known as hemarthrosis.

Symptoms

The primary symptom of joint effusion is swelling in the affected joint. This may be accompanied by other symptoms such as pain, stiffness, and limited range of motion. In severe cases, joint effusion may also cause fever, redness, and warmth in the affected area.

Diagnosis

Diagnosis of joint effusion typically involves a physical examination and imaging tests such as X-ray, MRI, or ultrasound. In some cases, a sample of the joint fluid may be taken for analysis, a procedure known as arthrocentesis.

Treatment

Treatment for joint effusion depends on the underlying cause. This may involve medication to reduce inflammation and pain, physical therapy to improve joint function, or in severe cases, surgery to remove the excess fluid or repair the damaged joint.
