Unexpected positive cultures in revision total knee arthroplasty after unicompartmental knee arthroplasty.

Purpose: Unexpected positive cultures are defined as a single positive culture in intraoperative samples taken during revision surgery after prosthetic joint infection was preoperatively ruled out. This study aims to determine the prevalence of unexpected positive cultures (UPC) in revision total knee arthroplasty (TKA) after unicompartmental knee arthroplasty (UKA). As a secondary objective, this study aims to compare the re-intervention rate in this specific group, between UPC and non-UPC patients.

Periprosthetic joint infections in patients with rheumatoid arthritis are associated with higher complication and mortality rates.

Introduction: Periprosthetic joint infection (PJI) remains the most devasting complication after total joint arthroplasty (TJA). There has been a significant focus on this topic in recently-published medical literature. However, relatively little has been published about PJI in patients with rheumatoid arthritis (RA), which are often physiologically frail and immunocompromised.

A secure blood-saving protocol for Jehovah's Witnesses in primary total hip replacement.

Objectives: The study aimed to analyze the efficacy of the blood management protocol developed by our team for patients who are Jehovah's Witnesses (JW) presenting for primary total hip replacement (THR).

Patients And Methods: Thirty JW patients (6 males, 24 females; mean age: 70.1±9.

Disseminated Erysipelothrix rhusiopathiae with Secondary Prosthetic Hip Joint Infection: A Case of Successful Identification and Management in a Regional Hospital.

Case: This article reports a case of a 72-year-old man with bilateral total hip joint replacements who suffered cuts to his hands while butchering a wild boar. He presented to the emergency department with fevers and unilateral hip pain. Erysipelothrix rhusiopathiae (E.

Unexpected positive cultures in patients with arthrofibrosis following total hip and total knee arthroplasty.

Purpose: It has been suggested that low-grade infections could be the cause of arthrofibrosis. However, this hypothesis has not been conclusively proven. The aim of this study is to assess the incidence of unexpected positive cultures (UPC) in patients undergoing revision total joint arthroplasty for a diagnosis of arthrofibrosis.

What is the rate of reinfection with different and difficult-to-treat bacteria after failed one-stage septic knee exchange?

Purpose: Re-operation after septic failure of a one-stage exchange for prosthetic joint infection (PJI) of the knee is a highly challenging procedure with concerns over residual bone stock, soft tissues, and stability. The associated changes in microbiology in cases of reinfection are still largely unknown.

Methods: A comprehensive analysis was performed of all patients treated at our tertiary institution between 2001 and 2017 who developed reinfection after a one-stage exchange for PJI of the knee.

Outcomes following non-operatively managed periprosthetic fractures surrounding uncemented femoral stems.

Background: The primary aim of this study was to explore the outcomes of Vancouver B periprosthetic hip fractures that were managed non-operatively with a particular focus on 1-year mortality. Understanding this mortality data will allow surgeons to better understand the risk associated with non-operative management. The secondary aim was to evaluate our case series and current literature with regards to identifying suitable patients for non-operative treatment.

Results of the first 1,000 procedures after resumption of elective orthopedic services following COVID-19 pandemic: Experiences of a high-volume arthroplasty center.

Objectives: This study aims to investigate the effectiveness of a screening questionnaire to identify high-risk patients for novel coronavirus-2019 (COVID-19) among those undergoing elective orthopedic surgery.

Patients And Methods: Between May 4th, 2020 and June 11th, 2020, a total of 1,021 consecutive patients (492 males, 529 females; mean age: 62.3±15.

Complication rates are low with the use of Stimulan calcium sulphate based antibiotic delivery system in the management of patients with hip-related PJI: early results of a consecutive case series.

Background: Effective management of prosthetic joint infection (PJI) requires prolonged, sustained delivery of antibiotics to the effective joint space. Calcium sulphate antibiotic delivery systems have been used in this setting, however, potentially serious complications including symptomatic hypercalcaemia have been described. There is relatively little prospective data on the results with the use of these compounds.

Defensive antibacterial coating in revision total hip arthroplasty: new concept and early experience.

Background: Infections remains the most feared complication in total hip arthroplasty (THA). New strategies of PJI prevention includes coating of conventional implants. Defensive Antibacterial Coating (DAC), an antibacterial hydrogel coating made of hyaluronan, poly-D and L-lactide can protect biomaterials as an effective barrier at the time of implantation.
