Treatment Of Acute Septic Arthritis Research Articles

An update on recent progress of the epidemiology, etiology, diagnosis, and treatment of acute septic arthritis: a review.

Acute septic arthritis is on the rise among all patients. Acute septic arthritis must be extensively assessed, identified, and treated to prevent fatal consequences. Antimicrobial therapy administered intravenously has long been considered the gold standard for treating acute osteoarticular infections. According to clinical research, parenteral antibiotics for a few days, followed by oral antibiotics, are safe and effective for treating infections without complications. This article focuses on bringing physicians up-to-date on the most recent findings and discussions about the epidemiology, etiology, diagnosis, and treatment of acute septic arthritis. In recent years, the emergence of antibiotic-resistant, particularly aggressive bacterial species has highlighted the need for more research to enhance treatment approaches and develop innovative diagnosis methods and drugs that might combat better in all patients. This article aims to furnish radiologists, orthopaedic surgeons, and other medical practitioners with contemporary insights on the subject matter and foster collaborative efforts to improve patient outcomes. This review represents the initial comprehensive update encompassing patients across all age groups.

Efficacy of Lavage by Tube under Local Anesthesia versus Arthroscopic Treatment of Acute Septic Arthritis of Native Knee.

Although arthroscopic treatment is a minimally invasive surgery that effectively treats septic arthritis of the knee joint, it requires general or regional anesthesia. This study aimed to compare the clinical results of lavage after tube insertion versus arthroscopic treatment. Patients treated with arthroscopic treatment were included in group I (n = 76), while those treated with lavage by tube were included in group II (n = 34). We investigated the following in all patients: demographics, underlying disorders, initial serum white blood cell (WBC) count, C-reactive protein (CRP) level, synovial fluid WBC and polymorphonuclear cell counts, causative organism, initial Kellgren-Lawrence grade, lavage number, interventional delay, hospitalization days, CRP normalization time, and Western Ontario McMaster Universities Osteoarthritis index scores for clinical outcomes at 3 months postoperative. The mean interventional delay was significantly greater in group I (23.6 ± 15.6 h vs. 8.7 ± 9.3 h, p < 0.001). The lavage by tube featured a significantly shorter interventional delay time than arthroscopy, while the CRP decrease rate did not differ between groups. Moreover, lavage by tube showed no significant differences in outcomes, including laboratory results and functional outcomes at 3 months postoperative.

Eradication and graft retention can be achieved in the treatment for acute septic arthritis after primary posterior cruciate ligament reconstruction: analysis of 1561 reconstructions.

Acute septic arthritis after arthroscopic posterior cruciate ligament (PCL) reconstruction is a rare but severe complication. Optimal management has not been established. The purposes of this study were to analyze clinical findings and to retrospectively evaluate the graft-retaining treatment regimen. From 2010 to 2021, a total of 1561 primary PCL reconstructions were performed at our institution. Seven patients with septic arthritis were identified and retrospectively analyzed with regard to incidence, clinical manifestations, treatment, postoperative clinical course and follow-up results. The mean interval from PCL reconstruction to the onset of symptoms was 11.0 ± 4.0days. Staphylococcus aureus was the most commonly found pathogen. Eradication was achieved in all patients after a mean of 1.1 ± 0.4 procedures, with graft retention in all patients. The mean duration of antibiotic treatment was 5.7 ± 1.5weeks. At the last follow-up, there was no recurrence, graft insufficiency or osteoarthritis. Arthroscopic graft-retaining treatment combined with individual antibiotic therapy, eradication and good to excellent functional results can be achieved, which might encourage surgeons to try to retain the graft as much as possible. Level IV.

Clinical Efficacy of the Antibiotic-Loaded Collagen Sponge During Arthroscopic Treatment of Acute Septic Arthritis of the Native Knee.

Background:To completely eliminate an infection, the antibiotic concentration must exceed the minimum inhibitory concentration for the causative pathogens. The antibiotic-loaded collagen sponge (ALCS) has been used to manage an infection through a high local concentration of antibiotics.Purpose:To evaluate the clinical efficacy of ALCS in the arthroscopic treatment of patients with acute septic arthritis of the native knee.Study Design:Cohort study; Level of evidence, 3.Methods:The authors retrospectively reviewed the data for 132 consecutive patients with acute septic arthritis of the knee who underwent arthroscopic debridement between 2013 and 2019. Patients with a history of surgery in the affected joint, concomitant osteomyelitis, or accompanying medical infection were excluded. The study patients were divided into 2 groups based on the use of ALCS during surgery. C-reactive protein (CRP) levels were temporally measured to normalization and the duration of intravenous antibiotic administration was recorded, and the mean length of hospital stay was compared between the groups. Independent t test and chi-square test were performed to assess differences between the groups, and univariate analysis was used to analyze factors affecting recurrence of septic arthritis.Results:Of the 132 patients, 88 were ultimately included in this study; 51 patients were managed without ALCS and 37 were treated with ALCS. There were statistically significant differences between groups in the mean period for CRP-level normalization (15.2 ± 8.2 days [ALCS] vs 26.2 ± 14.7 days [without ALCS]; P = .004), mean duration of intravenous antibiotic use (18.4 ± 7.3 days [ALCS] vs 26.6 ± 16.1 days [without ALCS]; P = .046), and mean length of hospital stay (21.1 ± 11.6 days [ALCS] vs 30.3 ± 18.3 days [without ALCS]; P = .045). The preoperative CRP level was the only significant risk factor for recurrence or treatment failure after single arthroscopic debridement.Conclusion:The results of this study indicated that ALCS was able to reduce the duration of CRP-level normalization, intravenous antibiotic use, and hospitalization in patients who underwent arthroscopic irrigation and debridement for acute septic arthritis of the native knee.

Development of an experimental model of septic knee arthritis in rats through intra-articular inoculation of Staphylococcus aureus.

Haematogenous models of septic arthritis have some inherent disadvantages, such as the manifestation of arthritis relies on chance, the size of the inoculum is unknown and the number of animals to be studied cannot be reduced because the animals cannot serve as their own controls. This study aimed to develop a rat model of knee septic arthritis by injecting a known inoculum of Staphylococcus aureus into the joint. The left knees of 27 Sprague Dawley rats were injected with four different inoculum concentrations of a sensitive strain of S. aureus (30,000 colony-forming units (CFUs), n = 3; 18,550 CFUs, n = 6; 15,500 CFUs, n = 9; and 7700 CFUs, n = 9); the right knees served as controls. Clinical, microbiological and histological variables were assessed two and seven days later. The main criterion for diagnosing septic arthritis was a positive culture of synovial fluid. The rate of microbiologically confirmed septic arthritis was high for all inoculum concentrations (3/3, 6/6, 8/9 and 7/9, respectively), and the rate of bacteraemia was also high. Animal welfare was better for the two lowest inoculum concentrations. No animal reached the pre-established humane end points. Overall, the third inoculum was considered the most suitable. Thus, acute septic arthritis can be caused in rats by inoculating 15,000 CFUs of an ATCC strain of S. aureus directly into the knee joint. Overall, the model seems to be useful for studying the effectiveness of drugs for the treatment of acute septic arthritis.

The Prognostic Value of a Novel Magnetic Resonance Imaging-Based Classification for Septic Arthritis of the Shoulder.

The purposes of the present study were (1) to create a magnetic resonance imaging (MRI)-based classification system for septic shoulder arthritis and to show the results of arthroscopic debridement based on the classification in eradicating the infection, and (2) to determine the distribution of the Gächter stages, which are determined on the basis of arthroscopic findings only, in each grade of the novel classification system. The present study included 31 patients who underwent arthroscopic debridement for the treatment of acute septic arthritis of the shoulder between January 2001 and December 2015. The mean duration of follow-up was 2.3 years. The included patients were assessed with use of a novel classification system based on preoperative radiographic and MRI findings. MRI findings were classified as Grade I (only synovitis or joint effusion), Grade II (marrow edema in the bare area of the humeral head), Grade III (cartilaginous erosion), Grade IV (osseous erosion), and Grade V (osseous erosion on MRI also observed on radiographs). No changes on radiographs were observed in Grades I to IV. The intraclass correlation coefficients (ICCs) for interobserver and intraobserver reliability were calculated. The overall reinfection rate was 54.8% (17 of 31). Among patients with Grade-I, II, III, IV, and V involvement, the reinfection rates were 0 of 4, 1 of 6, 2 of 4, 9 of 12, and 5 of 5, respectively. A diverse distribution of Gächter stages were found in each grade of the novel classification system, with the exception of Grade V. The ICCs for interobserver and intraobserver reliability were 0.81 and 0.80 for the novel classification system. The ICCs for interobserver and intraobserver reliability were 0.75 and 0.78 for Gächter stages. This novel classification system for the grading of acute shoulder infections on the basis of radiographs and MRI allows preoperative grading of septic arthritis to be performed objectively. Patients who were classified as Grade III or higher in the novel classification system had higher reinfection rates than those who were classified as Grade I or II and required more aggressive treatment to eradicate the infection.

Arthroscopic Treatment of Acute Septic Arthritis of the Hip Joint in Pediatric Patients Aged 10 Years or Younger

To present the results of arthroscopic treatment of acute septic arthritis of the hip joint in children aged 10years or younger. Patients with a minimum follow-up period of 2years who underwent arthroscopic treatment (anterolateral and medial subadductor 2-portal approach) of acute septic arthritis of the hip joint between January 2014 and January 2017 were included in this retrospective case-series study. The exclusion criteria included fungal infection, late presentation (≥5 days after the onset of the symptoms), presence of concomitant osteomyelitis, osseous pathologic conditions on radiography suggesting osteomyelitis, immunocompromised condition, history of surgery or infection surgery from the affected extremity, immobility owing to neuromuscular pathologic conditions, and identification of inflammatory or reactive arthritis during follow-up. The diagnosis of septic arthritis was confirmed according to the Waldvogel criteria. Clinical outcomes were assessed according to the Bennett score and Harris Hip Score. We evaluated 15 hips in 15 patients (6 female and 9 male patients) with a mean age of 5.2years (range, 2-10years) in this study. The mean hospital stay was 4.2days (range, 3-7days), and the mean antibiotic-use period was 34days (range, 26-45days). The most causative pathogen was Staphylococcus aureus (40%) (including methicillin-sensitive S aureus) and was isolated and cultured in all patients. All patients had full range of motion of the hip joint. All of the Bennett scores were excellent; the mean Harris Hip Score was 96.3 (range, 92.5-100) after a minimum follow-up period of 24months (mean, 26.1 ± 3.2months; range, 24-35months). No patient needed additional surgical intervention. No degenerative changes or avascular necrosis developed. According to our results, arthroscopic treatment is an effective choice for the treatment of acute septic arthritis of the hip joint in children aged 10years or younger. Level IV, retrospective case series.

Treatment of acute shoulder infection: can osseous lesion be a rudder in guideline for determining the method of débridement?

There is no standard to determine the most appropriate method of operation for the treatment of acute septic arthritis of the shoulder joint. We retrospectively reviewed 57 patients who underwent arthroscopic or open débridement for acute shoulder infection between 2001 and 2015. Arthroscopic débridement was performed in 27 patients, and open débridement in 30 patients. According to the presence of bone erosion and/or marginal erosion of cartilage of the humeral head on plain radiographs and magnetic resonance imaging (MRI) images, the cases were classified into 3 groups (group 1, n = 23, without erosions in x-ray and MRI; group 2, n = 21, erosions seen in MRI but not in x-ray; and group 3, n = 13, with erosions seen in both x-ray and MRI). The arthroscopic group had a reinfection rate of 55.6% (15/27), and the open group had a reinfection rate of 16.7% (5/30). The reinfection rates in the arthroscopic and the open groups were 10% (1/10) and 15.4% (2/13) in group 1; 75% (9/12) and 11.1% (1/9) in group 2; and 100% (5/5) and 25% (2/8) in group 3, respectively. At the last follow-up, the mean University of California at Los Angeles score and the average time until normalization of white blood cell, erythrocyte sedimentation rate, and C-reactive protein in the open group showed superior results in the open group (all P < .05). When preoperative MRI showed bone and/or cartilage erosion of humeral head, the reinfection rate after arthroscopic débridement was above 75%. Therefore, if preoperative MRI showed erosions, open débridement is more likely to be appropriate than arthroscopic débridement.

Open Compared with Arthroscopic Treatment of Acute Septic Arthritis of the Native Knee.

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. 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. The clinical findings, laboratory evidence, arthrocentesis and microbiology results, knee radiographs, and outcomes were compared. There were 161 patients (166 knees) with acute native knee septic arthritis treated between 2000 and 2015. Initially, 123 knees were treated by arthroscopic irrigation and 43 knees were treated by open irrigation; however, 71% in the open treatment group required repeat irrigation compared with 50% in the arthroscopic treatment group. The superiority of an arthroscopic procedure persisted after adjustment for potential confounders by multivariable analysis, with an odds ratio of 2.56 (95% confidence interval, 1.1 to 5.9; p = 0.027). After 3 irrigation procedures, the cumulative success rate was 97% in the arthroscopic treatment group and 83% in the open treatment group (p = 0.011). The total number of irrigation procedures required was fewer in the arthroscopic treatment group (p = 0.010). In the arthroscopic treatment group, the mean postoperative range of motion was greater (p = 0.016) and there was a trend toward a shorter median length of stay (p = 0.088). Arthroscopic treatment for acute native knee septic arthritis was a more successful index procedure and required fewer total irrigation procedures compared with open treatment. Long-term postoperative range of motion was significantly greater following arthroscopic treatment. Therapeutic Level III.

Treatment of Acute Septic Arthritis

Acute septic arthritis is a rare, but potentially devastating disease. The treatment is initiated intravenously, but can be safely switched to oral after 2-4 days providing large doses of a well-absorbing antibiotic and, for time-dependent antibiotics, 4 times-a-day administration are used. Empiric treatment should always cover Staphylococcus aureus and common respiratory pathogens, whereas Kingella kingae and Salmonella are important only regionally. Studies conducted by our group have shown that a total course of 10 days may suffice for previously healthy children in a Western setting. Treatment of neonates, patients with immunodeficiency or cases caused by methicillin-resistant S. aureus, may deserve a different approach.

Arthroscopic treatment for acute septic arthritis of the hip joint in adults

The purpose of our study was to evaluate the efficacy and safety of the arthroscopic management of septic arthritis of the hip joint. From October 2009 to October 2010, nine patients with septic arthritis of the hip were treated with arthroscopic debridement and drainage and systemic antibiotics according to bacterial sensitivity or with empiric antibiotics if no bacteria was isolated from the cultures. All patients were placed in the supine position on a fracture table, and two or three arthroscopic portals were used. The medical records were retrospectively reviewed to determine the efficacy and safety of hip arthroscopy for septic arthritis. There were 4 men and 5 women, with a mean age of 49.8 years (SD 12.1). No major complication related to arthroscopy of the hip was encountered. Staphylococcus aureus was identified in 4 patients. Average follow-up was 19.4 months (SD 4.1). Septic arthritis relapsed in one patient, but the other 8 patients experienced no recurrence during the follow-up period. Arthroscopic lavage and debridement is a safe and effective procedure for septic arthritis of the hip joint.
