DAIR (Debridement, Antibiotics and Implant Retention) less effective in hematogenous total knee arthroplasty infections.

Background: Debridement and irrigation with prosthetic retention followed by antibiotic therapy (DAIR) is one of the treatments of choice in acute infections after a total knee arthroplasty. However, the success rate varies widely in the literature, depending on several factors such as comorbidities of the patient, duration of infection, and microorganisms involved. The goal of this study was to assess the outcomes of this therapeutic option and to identify possible predictors of the result.

Outcomes of Vancouver B2 and B3 periprosthetic femoral fractures after total hip arthroplasty in elderly patients.

Introduction:: The objective was to evaluate clinical and radiological outcomes of Vancouver B2 and B3 periprosthetic femoral fractures in patients older than 65 years treated at our institution from 2000 to 2014. We compared the most common methods of fixation: a modular tapered rectangular titanium stem versus a monoblock tapered stem.

Methods:: A retrospective review was performed with a minimum follow-up time of 2 years.
