Outsourcing elective surgery has become increasingly commonplace to meet increasing demand from a growing & aging population. There is concern that outsourcing was influencing the nature of residual workload that was unsuitable for treatment elsewhere. This led to the impression that our unit is operating on more complex patients orthopaedic problems, ASA and Body Mass Index (BMI). By losing a disproportionate number of straightforward patients our department's outcomes, productivity and training opportunities could be adversely affected. Retrospective analysis of prospectively collected data of primary hip / knee arthroplasties between July & December for 2014(pre-outsourcing), 2015 and 2016(post-outsourcing). ANOVA, Tukey Honest Significant Difference(HSD) and Pearson's correlation used. Total of 726
The majority of orthopaedic surgeons routinely review their patients after six weeks, following surgery. During the first six weeks, orthopaedic surgeons are blissfully unaware of how frequently their patients seek medical attention related to problems with their arthroplasty. During this period of time, General Practitioners play a vital role in the care of the post-operative arthroplasty patient. The aim of this study was to determine how frequently patients seek medical attention following
The aim of the present work was (i) to survey the situation of healthcare regarding the use of antibiotics in orthopaedics and trauma surgery in Germany, (ii) to determine which empiric antibiotic regimens are preferred in the treatment of periprosthethic joint infections (PJI) and (iii) to evaluate the hypothetical antibiotic adequacy of the applied empirical antibiotic therapy regimens based on a patient collective of a German university hospital. A survey on empirical and prophylactic antibiotic therapy was conducted at German university and occupational health clinics (BG clinics), each in the specialties of orthopedics and trauma surgery. A total of 71 clinics were contacted by email. The questionnaire sent included open-ended questions on systemic antibiotic prophylaxis in primary hip arthroplasty; a distinction was made between hip arthroplasty due to femoral fractures and elective hip arthroplasty. In addition, the empirical antibiotic therapy used in PJIs was surveyed. To determine the success rate of prophylaxis and therapy according to sensitivity to the antibiotics applied, the survey results were compared with previously published data on antimicrobial treatment in n=81 PJI patients treated in our department between 2017 and 2020.Aim

Hip and knee device sales representatives (reps) can provide intra-operative guidance through their knowledge of the products, especially in complicated cases such as revision hip and knee arthroplasty. However, for an experienced arthroplasty surgeon in the majority of straightforward primary cases, the rep's presence may not be required for clinical decision-makings. With recent challenges in cost savings and bundle payments, hospitals and surgeons have focused on reducing the implant costs, among others, with a “repless” model. The aim of this study was to describe the process of utilizing this model, assess its efficacy, and analyze the cost savings in primary hip arthroplasty. During the month of January 2016, 20 cases of primary, straightforward total hip arthroplasties were performed with the repless model by 2 experienced arthroplasty trained surgeons. All patients were followed prospectively for minimum 3 months. Prior to initiating the repless model, we focused on process management of the operating room with staff training and re-engineering of the trays to obtain a setup that included one hospital tray and one device company tray for each operation. The responsibilities of the rep were divided into 2 categories for better management:
Familiarity of the instruments, implant, and techniques; trays set up and assurance of availability of the implants. These responsibilities were covered by a trained OR technician and the surgeon Final verification of the accurate implants prior to opening the packaging. This was done by a trained OR nurse and the surgeonIntroduction

Prosthetic Joint Infection (PJI) remains one of the leading cause for revision arthroplasty.1,2 Early recognition and appropriate initial treatment of early PJI with debridement, antibiotics and implant retention (DAIR) can eradicate infection on first attempt and prevent implant failure. We evaluated the outcome after one year of patients who were treated for an early PJI after primary total knee arthroplasty (TKA) or total hip arthroplasty (THA) with DAIR. Furthermore, we determined preoperative infection markers, microbiology, and treatment factors related to treatment failure after DAIR procedure. A retrospective cohort study was assembled with 91 patients undergoing DAIR after primary TKA or THP with a high suspicion of an early PJI. For all patients intraoperative cultures were obtained. Records were reviewed for demographic details, preoperative laboratory results, microbiological data, given treatment and postoperative follow-up. The primary outcome measure was infection-free implant survival at one year. Repeated DAIR was not considered as treatment failure.Aim

Aim. Perioperative myocardial infarction/injury (PMI) is a common complication in noncardiac surgery, contributing to postoperative morbidity and mortality. We aimed to identify the risk for PMI in periprosthetic joint infection (PJI) in comparison to primary hip (THA) and knee arthroplasty (TKA) and to non-PJI revision surgery. Methods. Patients undergoing primary/revision THA/TKA at a University Hospital who were eligible for the institutional PMI screening and response program were prospectively included. Revision arthroplasties were divided into 2 groups (PJI revision and non-PJI revision). PJI was defined according to the EBJIS criteria, and included DAIR, one-stage and two-stage revisions. Non-PJI revisions included partial and/or complete exchange of components. The primary endpoint was PMI, secondary endpoints were major adverse cardiovascular events (MACE) and all-cause mortality within 120 days. Results. The study population included 673 patients (443 primary THA/TKA, 119 PJI revision, 111 Non-PJI revision) enrolled from 05/2014 to 06/2018. The median age in all groups was 75 years. In primary, non-PJI and PJI revision surgery, 39%, 41% and 50%, respectively were male. PMI occurred in 12% of patients with
Aim. Debridement, antibiotics and implant retention (DAIR) are considered as an optimal curative treatment option for prosthetic joint infection (PJI) when the biofilm is still immature and radical debridement is achievable. There are two main groups of patients suitable for DAIR. Those with an early acute PJI and patients with acute hematogenous PJI. However, there is also a third group of early PJI resulting from a wound healing problem or leaking hematoma. These may be either high or low grade depending on the microorganisms that infected the artificial joint “per continuitatem”. Methods. We retrospectively analysed 100 successive DAIR procedures on prosthetic hip and knee joints performed between January 2010 and January 2022, from total of 21000
Dual mobility is a French concept that appeared in the 1970s and was initially intended to reduce dislocation rates. In recent years, this concept has evolved with new HA titanium spray coatings, new external macrostructures, and better-quality polyethylene. This has allowed to extend the indications to younger and therefore active populations. The objective of our work is to analyze at least 10 years a homogeneous and continuous series of 170 primary total hip replacements associating a latest generation Novae Sunfit. ®. dual mobility cup with a straight femoral stem.

Direct anterior approach (DAA) arthroplasty has generated great interest because of its minimally invasive and muscle sparing nature. Obese patients are reported to be associated with greater incidence of complications in
Novel oral anticoagulant (NOAC) use in Australia has increased significantly since their introduction to the Pharmaceutical Benefits Scheme (PBS). Currently, there are no specific guidelines regarding recommencement of NOAC therapy post-operatively for patients concurrently on a NOAC and undergoing arthroplasty. To address this gap in the literature, the aim of this study was to compare the clinical and patient-reported outcomes in a patient cohort recommencing a therapeutic dose of NOAC within 24 hours of total hip or knee arthroplasty. Data was retrieved from a prospective registry (ACTRN1262000079698) containing hip and knee arthroplasties. Cases were labelled based on whether they presented on a therapeutic dose of NOAC prior to surgery or not. Descriptive statistics were used to summarise patient outcomes. Of 291 patients undergoing 331
Extended patient waiting lists for assessment and treatment are widely reported for planned elective joint replacement surgery. The development of regionally based Elective Orthopaedic Centres, separate from units that provide acute, urgent or trauma care has been suggested as one solution to provide protected capacity and patient pathways. These centres will adopt protocolised care to allow high volume activity and increased day-case care. We report the plan to establish a new elective orthopaedic centre serving a population of 2.4 million people. A census conducted in 2022 identified that 15000 patients were awaiting joint replacement surgery with predictions for further increases in waiting times. The principle of care will be to offer routine
Periprosthetic joint infection (PJI) in geriatric and/or multimorbid patients is an enormous challenge for orthopaedic surgeons. Revision procedures have also been demonstrated to expose patients to higher infection risks. Prior patient stratification according to presumed infection risks, followed by a more potent local antibiotic prophylaxis protocol with selective use of DALBC, is an interesting strategy to decrease the burden of PJI in high risk patients. The PubMed & EMBASE databases were screened for publications pertaining to the utilization of DALBC in cement for infection prophylaxis & prosthesis fixation. 6 preclinical & 7 clinical studies were identified which met the inclusion criteria and were stratified by level of clinical evidence. Only those studies were considered which compared the PJI outcome in the DALBC vs the SALBC group. (1). DALBC have been shown to exert a much stronger and longer lasting inhibition of biofilm formation on many PJI relevant bacteria (gram-positive and gram-negative pathogens) than single gentamicin-only containing cements. (2). DALBC use (COPAL G+C) in the intervention arm of 7 clinical studies has led to a significant reduction of PJI cases in a) cemented hemiarthroplasty procedures (3 studies, evidence level I and III), in b) cemented septic revision surgeries (2 studies, evidence level III), in c) cemented aseptic knee revisions (1 study, evidence level III) and in d) cemented
In 2020, the COVID-19 pandemic meant that proceeding with elective surgery was restricted to minimise exposure on the wards. In order to maintain throughput of elective cases, our hospital was forced to convert as many cases as possible to same day procedures rather than overnight admission. In this retrospective analysis we review the cases performed as same day arthroplasty surgeries compared to the same period 12 months previous. We conducted a retrospective analysis of patients undergoing total hip and knee arthroplasties in a three month period between October and December in 2019 and again in 2020, in the middle of the SARS-CoV-2 pandemic. Patient demographics, number of out-patient
Acetabulum fractures caused by civilian firearms represent a unique challenge for orthopaedic surgeons. Treatment strategies should include the assessment of infection risk due to frequently associated abdominal injuries and maintenance of joint function. Still, internationally accepted treatment algorithms are not available. The aim of the study was to increase knowledge about civilian gunshot fractures of the acetabulum by describing their characteristics and management at a high-volume tertiary hospital. All adult patients admitted to our hospital between January 2009 and December 2022 with civilian gunshot fractures of the acetabulum were included in this descriptive retrospective study. In total our institution treated 301 patients with civilian gunshot fractures of the hip joint and pelvis during the observation period, of which 54 involved the acetabulum. Most patients were young males (88,9%) with a mean age of 29 years. Thirty patients (55,6%) had associated intraabdominal or urological injuries. Fracture patterns were mostly stable fractures with minor joint destruction amenable to conservative fracture treatment (n=48, 88,9%). Orthopaedic surgical interventions were performed in 21 patients (38,9%) with removal of bullets in contact with the hip joint via arthrotomy or surgical hip dislocation as most frequent procedures. Most patients received antibiotics on admission (n=49, 90,7%). Fracture related infections of the acetabulum were noted in six patients (11,1%) while the mortality in the study population was low with one demised patient (1,9%) due to the trauma burden. Most civilian acetabulum gunshot fractures are associated with intraabdominal or urological injuries. In comparison to the literature on extremity gunshot fractures, there is an increased risk of infection in our study population. The decision for surgical wash-out and bullet removal should be based on contamination and anticipated joint destruction, while osteosynthesis or
The optimum indications for debridement, antibiotics and implant retention (DAIR) are unclear. Previous studies have demonstrated higher success rate of DAIR within one year of the
Arthroplasty procedures in low-income countries are mostly performed at tertiary centers, with waiting lists exceeding 12 to 24 months. Providing arthroplasty services at other levels of healthcare aims to offset this burden, however there is a marked paucity of literature regarding surgical outcomes. This study aims to provide evidence on the safety of arthroplasty at district level. Retrospective review of consecutive arthroplasty cases performed at a District Hospital (DH), and a Tertiary Hospital (TH) in Cape Town, between January 2015 and December 2018. Patient demographics, hospital length of stay, surgery related readmissions, reoperations, post-operative complications, and mortality rates were compared between cohorts. Seven hundred and ninety-five
Aim. Debridement, antibiotics, and implant retention (DAIR) is a viable treatment option for acute periprosthetic joint infections (PJI). The landmark DATIPO trial of Bernard et al. concluded that six weeks is not non-inferior to 12-week antibiotic therapy for DAIR. However, it is unknown if suppressive antibiotic treatment (SAT) would improve patient outcomes. Therefore, our study aims to evaluate the utility of SAT after 12 weeks of therapy. Method. We performed a retrospective study of patients with acute hip or knee PJI managed with DAIR at five institutions; in the U.S. (n=1), Netherlands (n=3), and Spain (n=1) from 2005–2020. We analyzed the effect of SAT using a Cox model among patients after 12 weeks of antibiotic treatment. The primary covariate of interest was whether the patient was on antibiotics after week 12, which was coded as a time-varying covariate. We decided a-priori to control for the clinically important risk factors such as age, sex, type of infection, modular exchange, joint, and presence of bacteremia and Staphylococcus aureus. We excluded patients who died, had treatment failure, or were lost to follow-up before 12 weeks. We defined treatment failure as infection recurrence (same or different organism), unexpected reoperation, or death due to infection. Results. There were 504 patients included in the study. The majority were female (58%, n=292), with a mean age of 70 years ago (SD 11). Hips and knees were equally proportioned.
