arthrocentesis

[ahr″thro-sen-te´sis]

surgical puncture of a joint cavity for aspiration of fluid.

ar·thro·cen·te·sis

(ar'thrō-sen-tē'sis),

Aspiration of fluid from a joint performed by needle puncture.

[arthro- + G. kentēsis, puncture]

arthrocentesis

/ar·thro·cen·te·sis/ (ahr″thro-sen-te´sis) puncture of a joint cavity with aspiration of fluid.

arthrocentesis

[är′thrōsintē′sis]

Etymology: Gk, arthron + kentesis, pricking

the puncture of a joint with a needle and the withdrawal of fluid, performed to obtain samples of synovial fluid for diagnostic purposes. It may also be used to instill medications and to remove fluid from joints to simply relieve pain. A local anesthetic is usually administered; surgical asepsis is observed in the procedure. Normal synovial fluid is a clear, straw-colored, slightly viscous liquid that forms a white, viscous clot when mixed with glacial acetic acid; if inflammation is present, as in rheumatoid arthritis, the fluid is watery and turbid, and its mixture with glacial acetic acid results in a flocculent, easily broken clot. The number of leukocytes, especially polymorphonuclear cells, and the protein content are increased, and the glucose level is decreased if inflammation is present. Synovial fluid samples are also cultured and examined microscopically to diagnose a septic process, such as bacterial arthritis.

Arthrocentesis

arthrocentesis

A procedure in which a needle is introduced into a joint and fluid removed for diagnostic or therapeutic purposes.

Diagnostic indications
Idiopathic joint effusions or arthritic complaints, suspected infectious arthritis, suspected gout, monitoring of antibiotic response in patient with septic arthritis.

Therapeutic indications
Decompress painful joint effusion, evacuate pus from a septic joint, remove inflammatory infiltrate and crystals in patient with gout, inject corticosteroids.
