What is arthrocentesis?

Explanation:
Collecting fluid from a joint with a needle and syringe defines arthrocentesis. This procedure withdraws synovial fluid for analysis or to relieve joint swelling, helping diagnose conditions like septic arthritis, inflammatory or crystal-induced arthritis, and to monitor disease. It is not surgical replacement of a joint (that would be arthroplasty), not collection of urine (that would be a urinary sample collection), and not injection into a joint (that would be an intra-articular injection to deliver medication).
