Use of a leukocyte esterase strip test may be a reliable tool to diagnose persistence of infection during second-stage revision procedures for periprosthetic joint infection, according to results.
Researchers collected synovial fluid for leukocyte esterase measurement among 76 patients who underwent a two-stage exchange for periprosthetic joint infection between July 2015 and April 2020. The synovial fluid collection occurred during surgery before arthrotomy in 79 procedures, according to researchers. Researchers generated receiver operating characteristic curves and calculated sensitivity,
