Aims. Patients with metabolic syndrome (MetS) are known to be at increased risk of postoperative complications, but it is unclear whether MetS is also associated with complications after total hip arthroplasty (THA) or total knee arthroplasty (TKA). Here, we perform a systematic review and meta-analysis linking MetS to postoperative complications in THA and TKA. Methods. The PubMed, OVID, and ScienceDirect databases were comprehensively searched and studies were selected and analyzed according to the guidelines of the Meta-analysis of Observational Studies in Epidemiology (MOOSE). We assessed the methodological quality of each study using the Newcastle-Ottawa Scale (NOS), and we evaluated the quality of evidence using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Data were extracted and meta-analyzed or qualitatively synthesized for several outcomes. Results. Ten cohort studies involving 1,352,685 patients were included. Qualitative analysis suggested that MetS was associated with a higher incidence of cardiovascular events, and meta-analysis showed that MetS increased the risk of all-cause complications (risk ratio (RR) 1.55, 95% confidence interval (CI) 1.28 to 1.89), surgical site infection (SSI; RR 2.99, 95% CI 1.30 to 6.90), urinary tract infection (UTI; RR 2.58, 95% CI 1.03 to 6.43), and 30-day readmission (RR 1.45, 95% CI 1.33 to 1.59). There was insufficient evidence for assessing an association between MetS and venous thromboembolism events, pulmonary or gastrointestinal complications, or
The Nottingham Hip Fracture Score (NHFS) was
developed to assess the risk of death following a fracture of the
hip, based on pre-operative patient characteristics. We performed
an independent validation of the NHFS, assessed the degree of geographical
variation that exists between different units within the United
Kingdom and attempted to define a NHFS level that is associated

The coronavirus disease 2019 (COVID-19) pandemic has led to unprecedented challenges to healthcare systems worldwide. Orthopaedic departments have adopted business continuity models and guidelines for essential and non-essential surgeries to preserve hospital resources as well as protect patients and staff. These guidelines broadly encompass reduction of ambulatory care with a move towards telemedicine, redeployment of orthopaedic surgeons/residents to the frontline battle against COVID-19, continuation of education and research through web-based means, and cancellation of non-essential elective procedures. However, if containment of COVID-19 community spread is achieved, resumption of elective orthopaedic procedures and transition plans to return to normalcy must be considered for orthopaedic departments. The COVID-19 pandemic also presents a moral dilemma to the orthopaedic surgeon considering elective procedures. What is the best treatment for our patients and how does the fear of COVID-19 influence the risk-benefit discussion during a pandemic? Surgeons must deliberate the fine balance between elective surgery for a patient’s wellbeing versus risks to the operating team and utilization of precious hospital resources. Attrition of healthcare workers or Orthopaedic surgeons from restarting elective procedures prematurely or in an unsafe manner may render us ill-equipped to handle the second wave of infections. This highlights the need to develop effective screening protocols or preoperative COVID-19 testing before elective procedures in high-risk, elderly individuals with comorbidities. Alternatively, high-risk individuals should be postponed until the risk of nosocomial COVID-19 infection is minimal. In addition, given the higher

Aims. Debate continues about whether it is better to use a cemented or uncemented hemiarthroplasty to treat a displaced intracapsular fracture of the hip. The aim of this study was to attempt to resolve this issue for contemporary prostheses. Methods. A total of 400 patients with a displaced intracapsular fracture of the hip were randomized to receive either a cemented polished tapered stem hemiarthroplasty or an uncemented Furlong hydroxyapatite-coated hemiarthroplasty. Follow-up was conducted by a nurse blinded to the implant at set intervals for up to one year from surgery. Results. A total of 115 patients died in the year after surgery. There was a tendency towards a slightly higher

Aims. Reconstruction of the acetabulum after resection of a periacetabular
malignancy is technically challenging and many different techniques
have been used with varying success. Our aim was to prepare a systematic
review of the literature dealing with these techniques in order
to clarify the management, the rate of complications and the outcomes. Patients and Methods. A search of PubMed and MEDLINE was conducted for English language
articles published between January 1990 and February 2017 with combinations
of key search terms to identify studies dealing with periacetabular
resection with reconstruction in patients with a malignancy. Studies
in English that reported radiographic or clinical outcomes were
included. Data collected from each study included: the number and
type of reconstructions, the pathological diagnosis of the lesions,
the mean age and follow-up, gender distribution, implant survivorship, complications,
functional outcome, and
To map literature on prognostic factors related to outcomes of revision total knee arthroplasty (rTKA), to identify extensively studied factors and to guide future research into what domains need further exploration. We performed a systematic literature search in MEDLINE, Embase, and Web of Science. The search string included multiple synonyms of the following keywords: "revision TKA", "outcome" and "prognostic factor". We searched for studies assessing the association between at least one prognostic factor and at least one outcome measure after rTKA surgery. Data on sample size, study design, prognostic factors, outcomes, and the direction of the association was extracted and included in an evidence map.Aims

Aims. Periprosthetic fracture is a significant complication of total
hip and knee arthroplasty. This study aimed to describe the survival
of patients sustaining periprosthetic femoral fractures and compare
this with that of the general population, as well as to identify
the factors that influence survival. Patients and Methods. A total of 151 patients (women: men 116:35, mean age 74.6 years,
standard deviation 11.5) that sustained a periprosthetic fracture
between January 2005 and October 2012 were retrospectively analysed.

Aims. The place of thromboprophylaxis in arthroplasty surgery remains
controversial, with a challenging requirement to balance prevention
of potentially fatal venous thrombo-embolism with minimising wound-related
complications leading to deep infection. We compared the incidence
of fatal pulmonary embolism in patients undergoing elective primary
total hip arthroplasty (THA) between those receiving aspirin, warfarin
and low molecular weight heparin (LMWH) for the chemical component
of a multi-modal thromboprophylaxis regime. Patients and Methods. A prospective audit database was used to identify patients who
had died within 42 and 90 days of surgery respectively between April
2000 and December 2012. A case note review was performed to ascertain
the causes of death. Results. During this period 7983 THAs were performed. The rate of mortality
was 0.43% and 0.58% at 42 and 90 days respectively. The groups comprised
1571 patients (19.7%) on warfarin, 1838 (23.0%) on LMWH and 4574
(57.3%) on aspirin. The 90-day
The aim of this study was to assess factors associated with the estimated lifetime risk of revision surgery after primary knee arthroplasty (KA). All patients from the Scottish Arthroplasty Project dataset undergoing primary KA during the period 1 January 1998 to 31 December 2019 were included. The cumulative incidence function for revision and death was calculated up to 20 years. Adjusted analyses used cause-specific Cox regression modelling to determine the influence of patient factors. The lifetime risk was calculated as a percentage for patients aged between 45 and 99 years using multiple-decrement life table methodology.Aims

The aim of this study is to determine the predictors of overall survival (OS) and predictive factors of poor prognosis of conventional high-grade osteosarcoma of the limbs in a single-centre in South Africa. We performed a retrospective cross-sectional analysis to identify the prognostic factors that predict the OS of patients with histologically confirmed high-grade conventional osteosarcoma of the limbs over ten years. We employed the Cox proportional regression model and the Kaplan-Meier method for statistical analysis.Aims

This study aimed to investigate the risk of postoperative complications in COVID-19-positive patients undergoing common orthopaedic procedures. Using the National Surgical Quality Improvement Programme (NSQIP) database, patients who underwent common orthopaedic surgery procedures from 1 January to 31 December 2021 were extracted. Patient preoperative COVID-19 status, demographics, comorbidities, type of surgery, and postoperative complications were analyzed. Propensity score matching was conducted between COVID-19-positive and -negative patients. Multivariable regression was then performed to identify both patient and provider risk factors independently associated with the occurrence of 30-day postoperative adverse events.Aims
