Review article: Joint aspiration for diagnosis of periprosthetic infection.

Author information

  • 1Department of Orthopaedics and Traumatology, Queen Mary Hospital, Hong Kong.


Joint aspiration is a reliable tool for diagnosis of periprosthetic infection. There are different indications, techniques, and approaches for joint aspiration. We recommend that it be performed selectively when infection is suspected clinically. The specimens should be interpreted based on the results of the culture as well as the white cell count and differential. Specimen collection, transport, and analysis should be prompt to ensure yield accuracy.
