Retrospective study demonstrates optimal specimen types and sites for cultures in periprosthetic joint infections, suggesting improved outcomes.
The MSP enhanced the yield of cultures without increasing the contamination rate. The optimal specimen types for culture included synovial fluid, interface membrane, and pseudocapsule. For hip, the optimal anatomical site for culture was femoral neck. For knee, the optimal anatomical site for culture was intercondylar area.
