Aims. The aim of this study was to establish the diagnostic accuracy
of culture of joint aspirate with and without saline injection-reaspiration. Patients and Methods. This is a retrospective analysis of 580 hip and knee aspirations
in patients who were deemed to have a moderate to high risk of infection,
and who subsequently proceeded to revision arthroplasty over a period
of 12 years. It was carried out at a large quaternary referral centre
where preoperative aspiration is routine. Results. Fluid was aspirated primarily in 313 (54%) cases and after saline
injection-reaspiration of a ‘dry tap’ in 267 (46%) cases. Overall
sensitivity and specificity of the diagnostic aspirate were 84%
(78% to 89%) and 85% (81% to 88%), respectively. Sensitivity and
specificity of saline injection-reaspiration after ‘dry tap’ were
87% (79% to 92%) and 79% (72% to 84%) compared with 81% (71% to
88%) and 90% (85% to 93%) for direct aspiration. Conclusion. Preoperative joint aspiration and culture is a sensitive and
specific test for the confirmation of diagnosis in patients at a
moderate to high risk of

We propose a state-of-the-art temporary spacer, consisting of a cobalt-chrome (CoCr) femoral component and a gentamicin-eluting ultra-high molecular weight polyethylene (UHMWPE) tibial insert, which can provide therapeutic delivery of gentamicin, while retaining excellent mechanical properties. The proposed implant is designed to replace conventional spacers made from bone cement. Gentamicin-loaded UHMWPE was prepared using phase-separated compression moulding, and its drug elution kinetics, antibacterial, mechanical, and wear properties were compared with those of conventional gentamicin-loaded bone cement.Aims
