Joint effusion

In musculoskeletal (MSK) ultrasound, a joint effusion refers to the abnormal accumulation of fluid within a joint capsule. This finding is crucial for diagnosing various conditions, including inflammatory arthritis, trauma, infection, or degenerative joint disease. Ultrasound offers a real-time, non-invasive method to detect, quantify, and characterize joint effusions, aiding in accurate clinical assessment and guiding aspiration or injection procedures.

Detecting a joint effusion via ultrasound is highly valuable in medical practice. Its ability to differentiate fluid from synovial hypertrophy and to identify associated pathology, such as synovitis or osteophytes, makes it an indispensable tool for musculoskeletal diagnosis and management. Timely identification and characterization improve patient outcomes.
