The Impact of the Multidisciplinary Team on the Management of Prosthetic Joint Infection in Trauma and Orthopaedic Surgery

Periprosthetic Joint Infection (PJI) is a devastating complication of the Total Joint Arthroplasty (TJA). It presents a great challenge for the clinician to diagnose and manage it appropriately, with significant morbidity for the patients and cost for health care providers. The purpose of this study is to review and examine the role of multi-disciplinary team (MDT) approach in diagnosis and management of prosthetic joint infection (PJI) and how this approach can influence outcomes. All published literature examining the role of multidisciplinary care in the management of PJI and the influence of this approach to the management and outcomes of patients with this diagnosis were included. Studies published in languages other than English were excluded. There is a paucity of data on the influence of multidisciplinary care on outcomes of the management of PJI. Evidence suggests that the MDT has important role in ensuring all factors in the management of this complex group are considered and best possible care is delivered. Multicentre randomised clinical trials are required to assess the influence of MDT’S on outcome as well as important questions around the structuring of these teams

Revision of failed hip resurfacing to total hip arthroplasty rapidly relieves pain and improves function in the early post operative period

We reviewed the results of 25 consecutive patients who underwent revision of a hip resurfacing prosthesis to a total hip replacement. Revisions were performed for recurrent pain and effusion, infection and proximal femoral fractures. Both components were revised in 20 cases

Three Cases of Femoral Stem Failure in Rotating Hinge Revision Total Knee Arthroplasty: Causes and Surgical Considerations.

Catastrophic failure of stemmed components in arthroplasty is an uncommon but a serious complication. Stem fractures and techniques for addressing these have been described following hip arthroplasty but much less so following total knee arthroplasty (TKA). We review three cases of catastrophic failure of the stem in rotating hinge revision TKA prostheses. We discuss the possible mechanism of failure and review the current literature addressing this topic. Metaphyseal support needs to be optimized in order to minimize load transfer to the stem and to the junction (and the risk of fracture) if a modular component is used. When constrained components are used, radiographs need to be carefully assessed for signs of proximal loosening. Nonmodular stems are also an option in this situation.This article is freely available under Open Access. Click on the Additional Link above to access the full-text via the publisher's site

Metal on metal hip resurfacing versus uncemented custom total hip replacement - early results

<p>Abstract</p> <p>Introduction</p> <p>There is no current consensus on the most appropriate prosthesis for treating symptomatic osteoarthritis (OA) of the hip in young, active patients. Modern metal on metal hip resurfacing arthroplasty (HR) has gained popularity as it is theoretically more stable, bone conserving and easier to revise than total hip arthroplasty. Early results of metal on metal resurfacing have been encouraging. We have compared two well matched cohorts of patients with regard to function, pain relief and patient satisfaction.</p> <p>Methods</p> <p>This prospective study compares 2 cohorts of young, active patients treated with hip resurfacing (137 patients, 141 hips) and custom uncemented (CADCAM) stems (134 patients, 141 hips). All procedures were performed by a single surgeon. Outcome measures included Oxford, WOMAC and Harris hip scores as well as an activity score. Statistical analysis was performed using the unpaired student's t-test.</p> <p>Results</p> <p>One hundred and thirty four and 137 patients were included in the hip replacement and resurfacing groups respectively. The mean age of these patients was 54.6 years. The mean duration of follow up for the hip resurfacing group was 19.2 months compared to 13.4 months for the total hip replacement group.</p> <p>Pre operative oxford, Harris and WOMAC scores in the THA group were 41.1, 46.4 and 50.9 respectively while the post operative scores were 14.8, 95.8 and 5.0. In the HR group, pre- operative scores were 37.0, 54.1 and 45.9 respectively compared to 15.0, 96.8 and 6.1 post operatively. The degree of improvement was similar in both groups.</p> <p>Conclusion</p> <p>There was no significant clinical difference between the patients treated with hip resurfacing and total hip arthroplasty in the short term.</p

Simultaneous or staged bilateral total hip arthroplasty? An analysis of complications in 14,460 patients using national data

Simultaneous bilateral total hip arthroplasty (SimBTHA) is often performed in younger, fitter patients with bilateral hip disease. If patients are deemed not suitable for SimBTHA due to concurrent comorbidity, it may be more appropriate to perform staged bilateral total hip arthroplasties (StBTHAs) 3-6 months apart to minimize complications and morbidity. Complication rates following hip arthroplasty are low and large national datasets are helpful for assessing these rare events. We aimed at comparing SimBTHA vs StBTHA in order to determine any differences in morbidity and mortality
