The Efficacy of Prophylactic Vancomycin in Decreasing Surgical Site Infections in Adolescent Idiopathic Scoliosis Patients: A Large Multicenter Cohort Study.

Background: The use of vancomycin powder in spine surgery has been supported in adult populations, however, its efficacy in preventing postoperative surgical site infections in AIS patients is yet to be determined.

Methods: A multi-center review was conducted from June 2010 to February 2019, using ICD and CPT codes to identify AIS patients who underwent primary PSF. The patients were divided into two groups: the vancomycin cohort (receiving local vancomycin powder prior to wound closure) and the non-vancomycin cohort.

Is severe medial knee osteoarthritis a risk factor for dissatisfaction following medial open-wedge high tibial osteotomy in patients 55 years of age or younger?

Introduction: Although previous studies have shown that severe medial knee osteoarthritis (OA) (Kellgren-Lawrence grade IV) is a risk factor for patient dissatisfaction following medial open-wedge high tibial osteotomy (MOWHTO), it is uncommon to perform arthroplasty as a primary surgical option in patients 55 years of age or younger. Thus, the purpose of our study was to evaluate whether severe medial knee OA is a risk factor for dissatisfaction following MOWHTO depending on patient age based on a cutoff of 55 years.

Material And Methods: We retrospectively reviewed the data of 270 consecutive patients who underwent MOWHTO with a minimum of 2 years of follow up.
