Short summary
Isolation of patients with musculoskeletal infections in orthopedic care is controversial. Evidence supports selective isolation for certain resistant pathogens but not for non-resistant pathogens, nor does it support the routine use of septic wards. Effective infection control depends on hospital-wide strategies and adherence to standard precautions, with specialized centres offering better care than dedicated isolation units.

Fracture-related infections (FRIs) and periprosthetic joint infections (PJIs) fail to recover pathogens, posing a diagnostic challenge and impacting treatment. This new method involves homogenising biopsies with beads to release bacteria, followed by inoculation in blood culture bottles using an automated system. This technique shows similar sensitivity to conventional methods, with improved specificity and faster pathogen detection. To date, no other studies have reported an optimized method for incubating biopsies from patients with FRIs.

Short summary
Sinus tracts communicating with the prosthesis demonstrated high specificity and support their use as a confirmatory criterion for periprosthetic joint infection (PJI). Purulence also showed high specificity but may be better considered to be a suggestive criterion due to challenges in clinical differentiation. Both findings were associated with distinct microbiological patterns and less favourable outcomes, highlighting their clinical relevance.

When infection around an artificial hip or knee is suspected, joint fluid sampling is essential but often unsuccessful. We performed a systematic review to evaluate whether rinsing the joint with sterile salt water after an unsuccessful attempt improves diagnosis. Our findings show that this approach is safe, yields testable fluid in nearly all cases, and identifies infection in about one in five patients that would otherwise be missed.

Segmental bone loss remains a major challenge, often worsened by fracture-related infection (FRI). Surgical debridement and tissue cultures are key initial steps. Bone transport, utilizing distraction osteogenesis, remains a key therapeutic strategy. Innovations like integrated fixation and motorized nails reduce patient morbidity. Management relies on a multidisciplinary approach. This review explores current and emerging concepts in the field of bone transport, focusing on FRI.

The aim of this proof-of-concept study was to investigate host immune gene expression through transcriptome profiling in patients with fracture-related infection and to explore the feasibility of detecting 16S rRNA and biofilm-associated genes, an approach not previously applied using this method. This technique revealed distinct immune activation patterns in fracture-related infection (FRI) and enabled the identification of pathogens that were missed by conventional culture techniques.

Founded in 2019, the Center for Musculoskeletal Infections at University Hospital Basel was established to implement standardized, multidisciplinary care for orthopaedic and trauma-related infections. This retrospective analysis of hip and knee periprosthetic joint infections (2019–2022) illustrates the feasibility and effectiveness of this structured approach, with infection control achieved in the majority of patients despite case complexity.

Although local antibiotic administration is used to prevent and treat fracture-related infections, concerns remain about systemic absorption and potential renal toxicity. This study assessed serum levels and renal function after local gentamicin or vancomycin use. Gentamicin exceeded the lower limit of quantification in 17% of cases but remained below toxic levels. Vancomycin was undetectable. These findings suggest that local antibiotic administration does not harm renal function.

Several factors have been linked to failure in chronic prosthetic joint infection revisions. We hypothesize that osteomyelitis in septic hip revisions is underestimated and may significantly impact outcomes. In this series, 30.8 % of septic revisions exhibited bone samples consistent with osteitis, mainly associated with prolonged unsuccessful surgical and antibiotic treatments, the presence of a sinus tract, and subsequent failure after implant removal.

A multi-center study of 563 periprosthetic joint infections (PJIs) found that 16.5 % were culture negative. These patients more often had prior revision or PJI, longer symptom duration and fewer systemic signs. On multivariable analysis, symptom duration >12 weeks was the only independent risk factor (odds ratio 2.24). The findings support the fact that culture-negative infections present insidiously, informing diagnostic strategies.

A total of 51 studies were reviewed to compare the alpha-defensin enzyme-linked immunosorbent assay (ELISA) and the lateral flow test for diagnosing joint replacement infections. Both tests are highly specific and accurately confirm infection, but ELISA showed greater sensitivity (87.8 % vs. 81.8 %), making it better for detection. These findings support the continued use of ELISA as the preferred diagnostic method.

The novel multiplex polymerase chain reaction (mPCR), BioFire® Joint Infection Panel (BF-JIP; bioMérieux, Marcy-l’Étoile, France), demonstrated similar diagnostic accuracy to conventional synovial fluid culture and can therefore serve as a valuable adjunct in diagnosing septic arthritis in adults, particularly in patients with prior antimicrobial therapy.

We assessed whether two debated scoring tools, KLIC and CRIME-80, could predict the failure of a treatment called debridement, antibiotics, and implant retention (DAIR) in prosthetic joint infections. We reviewed data from 102 patients. Neither score reliably predicted failure, even when the treatment was repeated. Our results highlight the limited clinical utility of these scores and support the need for better tools to guide treatment decisions in joint infections.

The Musculoskeletal Infection Society (MSIS) and the European Bone and Joint Infection Society (EBJIS) are comprised of experts in preventing, diagnosing, and managing orthopedic infections. In 2023, MSIS and EBJIS surveyed their membership about their approach to various clinical aspects of these challenging conditions. The results indicate that, even among experts, there remains substantial variability of practice. This variability reflects open questions in the field.

Short summary
Serum C-reactive protein, fibrinogen, and interleukin-6 show the best performance among serum markers for diagnosing periprosthetic joint infection (PJI), but they lack sufficient accuracy to confirm or exclude infection reliably. These markers should be re-evaluated in future PJI definitions, as they are not suitable as stand-alone tests. Given their limitations and the superior diagnostic performance of synovial markers, the role of serum markers in PJI diagnosis should be reconsidered.

This review assessed the effectiveness of single- and two-stage procedures for treating long-bone fracture-related infections, focusing on unhealed fractures without critical-sized bone defects. A total of 35 studies with 985 patients showed bone-healing rates of 80% for single-stage procedures and 77% for two-stage procedures. Infection eradication rates were 87% for single-stage approaches and 81% for two-stage approaches. The current evidence is inconclusive and lacks sufficient data to favor either approach.

This study's aim was to analyse the healing and failure rates of one-stage knee replacement in patients with positive and negative preoperative cultures and sinus presence. We concluded that culture-negative infections or the presence of a sinus tract showed similar results compared to patients that had undergone the same procedure with positive cultures or spared soft tissue.

Patients with rheumatoid arthritis have a high treatment failure rate when faced with a late acute periprosthetic joint infection. Because of the rarity of the condition, we performed a multicenter case-control study. We identified predictors of treatment failure to ultimately improve the treatment outcome. Exchange of modular components seems important in this patient group, likely due to a higher rate of positive blood cultures compared to control patients.

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.

When acute soft tissue defects are present after knee arthroplasty, the infection risk is high. A gastrocnemius flap is used for anterior defects, and it is not usually combined with debridement surgery unless infection is clear. We examined the benefit of combining coverage treatment with debridement surgery, DAIR, comparing the isolated traditional coverage treatment. The results suggested a higher healing rate in the combined treatment, so we recommended it.

This study validated three models for predicting infection after hip and knee replacement surgery. By analyzing data from 2684 patients in the Netherlands, Portugal, and Spain, we found that the models developed by Tan, Del Toro, and Bülow effectively identified high-risk patients. These models can be used to enhance preoperative counseling and to tailor infection prevention measures individually, potentially improving outcomes and reducing healthcare costs.

Skin commensal bacteria such as staphylococci are often the source of orthopaedic-device-related infections. Rifampicin is a widely used antibiotic in the treatment of these infections. The results of this study show that oral rifampicin therapy leads to a consistent and persistent induction of resistance in commensal staphylococci on the skin and in the nose for a prolonged time.

We assessed concordance of in-house guidelines for diagnostic principles and antibiotic treatment duration (ABT) 2 years after their implementation. The goal was to standardize diagnostic and treatment principles: are we doing what we recommend? The adherence to recommendations in terms of biopsy sampling was good, moderate for histopathology and poor for anatomic labeling. In terms of ABT duration, the adherence was good, but further shortening for surgically cured cases is necessary.

This study conducted in multiple sites across Europe aimed to evaluate the BIOFIRE Joint Infection (JI) Panel, a new technology that uses multiplex PCR to detect microorganisms in synovial fluid of patients with suspicion of joint infections in 1 h, in comparison with synovial fluid culture. Results showed an overall agreement of 85 % to 88.4 % between the two methods. The JI Panel detected additional organisms, and the positive user experience highlights its clinical significance.

We define an algorithm to optimize bone and joint infection diagnosis in adults on synovial fluid samples. This prospective multi-center study included a large number of synovial fluids and compared the performance of classical culture on different media, inoculation of synovial fluid in blood culture bottles, and broad-range and specific PCR. We proposed an algorithm associating culture onto three solid media and into blood culture bottles and 16S, Staphylococcus, and Streptococcus PCR.

Septic arthritis (SA) of the native adult hip is a rare orthopaedic emergency. To date, the role of advanced imaging has been confined to supporting or opposing diagnosis; however, implications for surgical decision-making and outcomes have not yet been established. We found that extra-articular abscesses are present in two out of three patients and require varying anatomical approaches. Therefore, we recommend routinely performing advanced imaging in all adults with SA of the native hip joint.

This is a meta-analysis of six studies describing the cutoff values of white blood cell count and polymorphonuclear percentage in synovial fluid for the diagnosis of acute postoperative peri-prosthetic joint infection (PJI).
We found that both the WBC count and PMN percentage are good markers for diagnosis of acute postoperative PJI. However, the synovial WBC count is more powerful in diagnosing acute postoperative PJI.

A total of 41 patients who underwent surgical treatment for septic arthritis (SA) of the native hip were studied. We show that patients with SA of the native hip can be divided in three distinct clinical subgroups based on route of infection. Route of infection is directly related to the chance of femoral head preservation and should, therefore, be the basis for decision-making. Only patients with blood-borne infections in an undamaged hip had a reasonable chance of femoral head preservation.

This international retrospective cohort study displays the diagnostic characteristics of 609 patients who were treated for fracture-related infection (FRI). Clinical confirmatory criteria were present in 77% of patients. In the remaining patients, the decision to operatively collect deep tissue cultures had to be based on a set of suggestive criteria. The combined use of these suggestive criteria should guide treating physicians in the management pathway of FRI.

While there is no gold standard test to diagnose periprosthetic joint infection (PJI), we believe synovial fluid analysis, especially preoperatively, is a critical step in differentiating between infection and aseptic failure. Adding simple and inexpensive biomarkers such as synovial C-reactive protein (CRP) or adenosine deaminase (ADA) and combined interpretation can be helpful in the context of inconclusive results.

In a first evaluation, the accuracy of a novel multiplex PCR (polymerase chain reaction) panel for rapid detection of pathogens in patients with a clinical suspicion of acute septic arthritis of native and prosthetic joints is assessed. Clear benefit is seen in patients with a suspected native septic arthritis and late acute prosthetic joint infection. This indicates that the panel allows for fast tailoring of antibiotics and may prompt the surgeon for surgical lavage in doubtful clinical cases.

Management of septic arthritis in native joints (SANJO) is often conducted by clinicians of different specialties, experience levels, and at all hours of the day. The SANJO guideline group makes evidence-based recommendations for diagnosis, microbiological investigation, initial surgery, empirical antibiotic treatment, early mobilization, evaluation of outcomes, and treatment failure. Special considerations were made for children, tuberculosis, and SANJO after cruciate ligament reconstruction.

We describe 48 osteocutaneous-flap-related osteomyelitis cases, mostly presenting with early, local signs of infection and/or bone exposure. Main pathogens were Gram-negative bacilli, streptococci, S. aureus, enterococci, and anaerobes, justifying a broad-spectrum empirical antimicrobial therapy. Despite surgery and a 3-month antimicrobial therapy, a 50 % failure rate was recorded, associated with a delayed infectious disease specialist referral and advocating for multidisciplinary management.

A patient with normal D-dimer value has a low risk of prosthetic joint infection, so serum D-dimer assessment should always be considered as a useful test to rule out chronic prosthetic joint infection (especially in those cases caused by low-virulence microorganisms in which conventional tests may lead to misdiagnosis). Conversely, the platelet count to mean platelet volume ratio may be of limited value for accurately diagnosing prosthetic joint infection.

A low-grade periprosthetic joint infection (PJI) may be difficult to diagnose, and nuclear imaging could help in the diagnosis. However, its diagnostic value is unclear. We retrospectively evaluated this diagnostic value. We conclude that in patients presenting with nonspecific symptoms and a low a priori chance of PJI based on clinical evaluation, nuclear imaging is of no clear added value in diagnosing a PJI.

Costs related to off-label expensive antibiotics used to treat bone and joint infections (BJIs) in a referral centre in France were analysed in this cohort study. Despite the large increase in the number of patients treated with these antibiotics, the overall costs remained stable (approximately EUR 1 million) and were helped by the appearance of generic molecules at lower prices. Production of generic antibiotics at low cost is essential to limit the financial burden of the management of BJIs.

Our data suggest that, in periprosthetic joint infection (PJI) patients with a draining sinus, suppressive antibiotic treatment (SAT) can be considered on an individual basis. SAT may reduce pain and favour the closure of the sinus tract in certain individuals, but the prescription of SAT does not appear to have any influence on the prevention of prosthetic loosening and other infectious complications.

When we initiated this paper, there was no evidence on what kind of spacers we should use. Our work was to prove that we must use a broad spectrum of antibiotics at the spacers in two-stage revision procedures. We demonstrate that a large spectrum of antibiotics at the spacer results in a lower rate of positive cultures during preimplantation and, subsequently, better outcomes and lower rate of infection.

We examined whether patients with musculoskeletal infections need to be separated in hospital. A review of published studies found no support for routine isolation or dedicated wards for infections without multidrug-resistant organisms when standard precautions are applied. An international survey showed wide variation in clinician attitudes. These findings highlight a gap between evidence and perception and support a more risk-based approach.
