This meta-analysis evaluates synovial fluid white blood cell count and polymorphonuclear neutrophil proportion in order to diagnose chronic peri-prosthetic joint infection. Based on 74 studies, it identifies optimal thresholds, with rule-in and rule-out thresholds enhancing diagnostic precision. Confounding factors such as fractures and inflammatory arthritis are addressed. The findings support standardized diagnostic frameworks in improving accuracy and clinical consistency.

This retrospective study shows that autogenous non-vascularized bone graft is a viable option for managing post-osteomyelitis bone defects in children in low-resource settings. Bone union was achieved in all cases at the last follow-up (minimum of 7 years). Recurrence of infection was seen in two cases. Studies into this specific technique are important as it does not require super-specialized centres or skills, both of which are scarce in low-resource settings.

Bone and joint infections are common and generally require surgical treatment combined with prolonged antibiotic therapy. It is important to use an antibiotic with good bone penetration that is effective against the commonly encountered pathogens and well-tolerated. Oral tetracyclines are promising and frequently used candidates. This review summarizes the available data on the use of oral tetracyclines in bone and joint infections and highlights the limited data available.

This is a summary of our position paper on debridement, antimicrobial therapy, and implant retention (DAIR) procedures as a curative treatment strategy for acute periprosthetic hip and knee infections. It includes the defined indications as well as the contraindications of DAIR procedures when eradication/cure is intended, based on the currently available literature. 

In this paper, we discuss the most relevant factors influencing the outcome and define indications, contraindications, and risk factors of a DAIR procedure based on the currently available literature. Furthermore, we discuss the surgical technique in combination with systemic antimicrobial therapy in patients undergoing a DAIR procedure.

This study evaluates dalbavancin, an antibiotic with a long duration of action, in treating complex bone and joint infections. It does not require daily dosing, allowing patients to leave the hospital earlier and reducing costs. Dalbavancin is shown to be effective and safe, especially for patients unsuitable for oral antibiotics or outpatient therapy, achieving similar results to traditional treatments while cutting healthcare costs.

In this article we discuss how gut microbiota can affect the outcomes of a total joint arthroplasty. Total joint arthroplasty is a safe procedure for improving the quality of life in patients affected by arthrosis. Periprosthetic joint infection (PJI) is relatively rare but represents one of the most common causes of implant failure requiring revision surgery. Recently, there has been a major interest in the role of gut microbiome, in particular dysbiosis, as a risk factor for PJI.

The desirability of outcome ranking (DOOR) combines joint function, infection cure and mortality into one outcome. Using the DOOR, we describe patient outcomes after prosthetic joint infection (PJI) treatment; moreover, debridement, antibiotics and implant retention (DAIR) is compared with two-stage exchange. Infections were classified as early (≤ 90 d post-arthroplasty) or late (> 90 d post-arthroplasty). For early PJI, DAIR was superior to two-stage exchange, whereas two-stage revision was superior to DAIR for late PJI.

Urgent analysis of joint fluid is a common test in patients with possible septic arthritis (bacterial infection of a joint). One aspect of this test, called the Gram stain, is considered important clinically, but previous single hospital studies have suggested it will miss a considerable number of infections. This large multi-hospital UK study assessed this test and found that it will miss 73 % of infections, questioning its value. More research on rapid tests using new technologies is required.

We compared the re-revision rates in rTHA and rTKA (revison total hip and knee arthroplasty) with and without AB (antibiotic) treatment in patients with UPICs (unexpected positive intraoperative cultures). The re-revision rate between the AB group and the non-AB group was similar. Postoperative AB treatment did not result in a decreased re-revision rate in patients with UPICs in presumed aseptic rTHA and rTKA. Patients with pathogens classified as a likely contaminant can be safely ignored.

This is a retrospective diagnostic study in acute postoperative prosthetic joint infection in total knee arthroplasty that wants to determine diagnostic accuracy of synovial glucose and serum-to-synovial glucose ratio in acute postoperative infection. Both tests demonstrated good diagnostic potential. Notably, these biomarkers exhibited superior accuracy compared to the combination of C-reactive protein, synovial white blood cell count and polymorphonuclear percentage.

We explore optimising antibiotic use to prevent infections in endoprosthetic replacement for bone tumours. We found 26 % of infections were linked to initial surgery, with most due to secondary factors like wound complications. The main bacteria are Staphylococcus aureus and coagulase-negative staphylococci. Our findings suggest targeting these bacteria with prophylactic antibiotics and applying measures to prevent secondary infections to improve infection control in orthopaedic oncology.

Our 10-year multicenter study examines the epidemiology, presentation, management, and outcomes of elbow native joint septic arthritis, a rare condition with risks like reoperation and mortality. Common symptoms included pain and swelling. Synovial fluid white blood cell counts were often low, with monosodium urate crystals also noted. Staphylococcus aureus was the main pathogen, and 72.2 % of patients underwent open debridement.

Our goal was to evaluate the results of two-stage revision of hip periprosthetic joint infection (PJI) over a 20-year period. Our arthroplasty unit is the largest in Ireland. We obtained data for a large number of cases (158 hips) with mid-term to long-term follow-up. Our analysis has found an infection-free survival rate of 84.2 % at 10 years, which was comparable with the best available outcomes. Most of the previously published risk factors were not predictive of failure in our study.

Antibiotics are often used to reduce the rate of recurrent periprosthetic joint infection (PJI) in patients with prior PJI. This study found that patients treated with such prophylactic antibiotics had an increased rate of infection with antibiotic-resistant organisms in any recurrent PJIs that occurred.
