We compared prosthetic joint infection (PJI) and acute kidney injury (AKI) rates among cohorts before and after changing our hospital's antimicrobial prophylaxis from cefuroxime to teicoplanin plus gentamicin for primary total joint arthroplasty. Switching to teicoplanin and gentamicin was associated with a significant risk reduction for PJI of 75.2 %. Significantly higher AKI rates were seen in patients receiving teicoplanin plus gentamicin; however, these were mild (KDIGO stage 1).

Orthopedic infections are complex, often requiring surgical intervention and prolonged antibiotic therapy, especially in the presence of a foreign body. In a rabbit model of implant-associated methicillin-resistant Staphylococcus aureus osteomyelitis, the lysins exebacase and CF-296 delivered locally with and without systemic daptomycin resulted in lower bacterial counts than those of control animals, showing a promising complement to conventional antibiotics in implant-associated infections.

Cutibacterium acnes is a bacterium responsible for most postoperative infections in orthopaedic shoulder surgery. There is currently a number of studies describing measures to reduce bacterial burden on the skin prior to surgery. In these studies it is rarely explained what bacterial sampling technique has been used. This study compares three different swab techniques and concludes that the new pencil eraser swab technique may be the best in detecting bacteria.
