This study explores the effectiveness of repeated debridement, antibiotics, and implant retention (DAIR) for early periprosthetic joint infections (PJIs) after total joint arthroplasty. It shows that repeated DAIR procedures may achieve over 75 % success, which indicates that this approach may have value in managing early PJIs after weighing the benefits and risks of repeated DAIR against implant removal for each patient.

Patients with rheumatoid arthritis have a high treatment failure rate when faced with a late acute periprosthetic joint infection. Because of the rarity of the condition, we performed a multicenter case-control study. We identified predictors of treatment failure to ultimately improve the treatment outcome. Exchange of modular components seems important in this patient group, likely due to a higher rate of positive blood cultures compared to control patients.

This retrospective study compared debridement and implant retention failure for three types of acute knee replacement infection and analyzed outcomes for patients in a cohort with low medical risk. No differences in failure rate were seen between types in the overall sample or “optimal” cohort. Staphylococcus aureus was less common in later infection, while Streptococcus was less frequent in earlier infection. In an optimal patient, similar outcomes between types may suggest that medical factors do not alter risk.

This study's aim was to analyse the healing and failure rates of one-stage knee replacement in patients with positive and negative preoperative cultures and sinus presence.  We concluded that culture-negative infections or the presence of a sinus tract showed similar results compared to patients that had undergone the same procedure with positive cultures or spared soft tissue.

We retrospectively compared outcomes of two-stage revision with three common spacer types. No significant difference in failure rate was seen across groups, contributing evidence of similar efficacy. Articulating spacers showed a greater range of motion than static spacers, and static spacers were associated with a higher adverse event rate, directly showing potential advantages and disadvantages of each variant. A trend toward a longer interstage duration for prosthetic spacers may reflect greater functionality.

Bone and joint infections often require prolonged antibiotic treatments over 12 weeks. Dalbavancin, an intravenous antibiotic given at spaced intervals, offers a promising option. Our study developed a method to optimize dosing schedules using two blood tests to measure drug levels. This ensures effective treatment while avoiding excessive accumulation. These findings suggest dalbavancin is a safe, effective choice for managing long-term infections.
