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.

Chronic Quadriceps Tendon Rupture After Total Knee Arthroplasty Augmented With Synthetic Mesh.

Tear of the quadriceps tendon after revision or primary total knee arthroplasty is a rare complication, but when it occurs, this injury has serious functional consequences. In complete tears, the outcome of direct repair is unpredictable, and several authors recommend that the suture should be reinforced. Several techniques have been described, including the use of autografts, allografts, and synthetic mesh.

Functional and radiological outcome of periprosthetic femoral fractures after hip arthroplasty.

Background: The aim of this study was to determine the functional and radiological results of the treatment of periprosthetic femoral fractures.

Materials And Methods: A review was performed of all periprosthetic femur fractures after a total hip arthroplasty (THA) or hemiarthroplasty (HA) treated at our institution from 1995 to 2011. Functional outcome was assessed in terms of the Harris Hip Score and ambulatory status.
