Risk of Infection After Septic and Aseptic Revision Total Knee Arthroplasty: A Systematic Review.

Background: The causes of primary total knee arthroplasty (TKA) failure can be divided into septic and aseptic etiologies. It is unclear whether the etiology affects the infection rate after revision TKA. This systematic review was conducted to evaluate whether there is a difference in infection rates between septic and aseptic revision TKA.

Computed tomography arthrography versus magnetic resonance imaging for diagnosis of osteochondral lesions of the talus.

Introduction: Osteochondral lesions of the talus (OLT) usually have non-specific clinical symptoms, and radiographs have a low sensitivity for detecting OLT. The purpose of this study is to compare the diagnostic value of CT arthrography (CTa) with that of MRI using arthroscopy as the reference standard for grading OLT.

Materials And Methods: We retrospectively reviewed patients who had OLT between 2015 and 2020.
