Despite the lack of validation, synovial aspiration remains a common practice during 2-stage septic revision total knee arthroplasty (TKA). The goal of this study was to investigate the diagnostic validity of synovial polymethylmethacrylate (PMMA) spacer aspiration of temporary knee arthrodesis to detect persistent periprosthetic joint infection before TKA reimplantation. This retrospective cohort study included 73 consecutive patients who underwent 2-stage septic revision TKA according to a standard protocol...

Dihydropyridine calcium-channel blockers are a known substrate for the cytochrome P450 isoform 3A4. Rifampicin, an antitubercular agent, is one of the most potent inducers of hepatic and intestinal CYP3A4 thus increasing dihydropyridine metabolism. We report a case of a 67-year-old hypertensive female treated with a 4-drug antihypertensive regimen including a dihydropyridine (nicardipine 50mg bid), who was admitted for septic arthritis of the knee requiring antibiotic treatment with teicoplanin 400mg od and rifampicin 600mg bid...

Some surgeons have been hesitant to use cementless fixation for total knee arthroplasty (TKA) in elderly patients due to concerns regarding successful bone biological fixation. Therefore, this study evaluated: (1) implant survivorship, (2) functional outcomes, (3) radiographic outcomes, and (4) complications in patients over 75 years of age who underwent cementless total knee arthroplasty. A total of 134 patients (142 TKAs) older than 75 years at a single institution between June 2008 and June 2014 were retrospectively reviewed...

BACKGROUND: Revision total knee arthroplasty (TKA) can often be challenging. The use of a new revision system may aid in providing better stability, improved function, fit, and implant longevity. Therefore, we assessed: (1) survivorship, (2) clinical outcomes, (3) postoperative complications, and (4) radiographic outcomes of patients who underwent revision TKA using this system. METHODS: Patients from 2 hospitals who underwent revision TKA using a newer generation revision knee system between June 2008 and December 2013 for component instability or aseptic loosening were included...

PURPOSE: Early treatment of septic arthritis is essential before irreversible damage to the articular cartilage occurs. Clinicians often start empirical antibiotic therapy for symptomatic relief while awaiting a definitive culture report. In present day parlance with variations in different centres in the private and public sector and rampant antibiotic abuse, a lot of resistance is being seen in the flora and their sensitivity patterns. Hence it is imperative to document and analyze these changing trends...

INTRODUCTION: Mucormycosis is a rare fungal infection, but can cause substantial morbidity and mortality in both immunocompromised and immunocompetent patients. Apophysomyces is a mucormycetes species ubiquitous in nature, particularly in soil, decaying wood and other organic matter. Apophysomyces is known to cause cutaneous fungal infections, particularly after penetrating trauma. Septic arthritis is a rare clinical manifestation. CASE PRESENTATION: We describe a case of Apophysomyces trapeziformis causing septic arthritis of the knee of a patient with multiple myeloma...

The genus Raoultella has been separated from the genus Klebsiella in 2001. Two main species are responsible for human infections: R. ornithinolytica and R. planticola. The most frequent infections due to R. planticola include cystitis, pneumonia and bacteremia (mostly in immunocompromised hosts). To date, no joint or bone infection has been reported. We describe the first case of septic arthritis due to R. planticola following an arthroscopy with intra-articular injection of corticosteroids. Evolution was favorable after arthroscopic lavage and antibiotic therapy with quinolones...

The incidence of Osteoarthritis (OA) is gradually increasing worldwide due to two main reasons: longer life expectation and increased functional demand. Several treatment options have been proposed for this disease. Conservative treatment has the goal to improve the quality of life, reduce pain, and prevent the progression of the disease. Hyaluronate viscosupplementation is one of the most used infiltrative treatments for OA, but, despite its common use, clinical efficacy is still under question. Though adverse reactions for this medical option are actually rare, septic arthritis is a very scaring complication...

RATIONALE: Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a severe drug-induced hypersensitivity reaction characterized by skin rash, fever, blood abnormalities, and multiple organ involvement. The diagnosis of DRESS syndrome is often delayed because of its variable presentation. Prompt withdrawal of the culprit drug is the definitive treatment. DRESS syndrome induced by antituberculosis drugs has rarely been reported. PATIENT CONCERNS: A 50-year-old man admitted to our hospital with recurrent episodes of progressive rash, fever, eosinophilia, lymphadenopathy, hepatic, and pulmonary involvement were experienced after repeat trials of the same antituberculosis drugs...

Acute pseudoseptic arthritis is a very rare complication that is associated with intra-articular hyaluronic acid injections, which normally involve minimal risk. The most common adverse events that are caused by hyaluronic acid injections are inflammatory reactions or flares at the injection site. In this study, we described three cases of acute pseudoseptic arthritis that was caused by hyaluronic acid; the symptoms in these cases were reminiscent of acute septic arthritis. Moreover, we performed a literature review on pseudoseptic arthritis following hyaluronic acid injections to determine the manner in which this condition can be described, diagnosed, and treated...

BACKGROUND: Periprosthetic joint infection (PJI) is a devastating complication following total joint arthroplasty. Current animal models of PJI are limited because of a lack of quantitative methods and failure to effectively recreate the periprosthetic space. We therefore developed a murine PJI model involving a 3-dimensionally printed Ti-6Al-4V implant capable of bearing weight and permitting quantitative analysis of periprosthetic bacterial load and evaluation of biofilm. METHODS: Twenty-five 12-week-old C57BL/6 mice received a unilateral proximal tibial implant and intra-articular injection of either 3 × 10 colony forming units (CFUs) of Staphylococcus aureus Xen 36 or saline solution...

BACKGROUND: Acute native knee septic arthritis is a joint-threatening emergency. Operative treatments by open or arthroscopic methods are available to surgeons. To our knowledge, the literature to date has primarily consisted of case series and no large study has yet compared these methods. The aim of this study was to compare open and arthroscopic treatment for acute native knee septic arthritis. METHODS: All adult patients with acute native knee septic arthritis treated at our institution with either open or arthroscopic irrigation from 2000 to 2015 were retrospectively evaluated...

We describe a case of septic arthritis in a native knee due to Corynebacterium striatum, gram-positive bacilli that are usually commensal organisms of skin and mucosal membranes, but are seldom implicated in native septic arthritis. An 84-year-old man with Corynebacterium striatum septic arthritis of his native left knee and no response to conventional antibiotic therapy. Thus, the patient was allowed to take dalbavancin for compassionate use, with an excellent clinical outcome. This case emphasizes de role of Corynebacterium striatum in native joint infections and highlights the importance of early detection and appropriate treatment in improving the clinical outcome...
