Total knee arthroplasty (TKA) and total hip arthroplasty
(THA) are recognised and proven interventions for patients with
advanced arthritis. Studies to date have demonstrated a steady increase
in the requirement for primary and revision procedures. Projected
estimates made for the United States show that by 2030 the demand
for primary TKA will grow by 673% and for revision TKA by 601% from
the level in 2005. For THA the projected estimates are 174% and
137% for primary and revision surgery, respectively. The purpose
of this study was to see if those predictions were similar for England
and Wales using data from the National Joint Registry and the Office
of National Statistics. Analysis of data for England and Wales suggest that by 2030,
the volume of primary and revision TKAs will have increased by 117%
and 332%, respectively between 2012 and 2030. The data for the United
States translates to a 306% cumulative rate of increase between
2012 and 2030 for revision surgery, which is similar to our predictions
for England and Wales. The predictions from the United States for primary TKA were similar
to our upper limit projections. For THA, we predicted an increase
of 134% and 31% for primary and revision hip surgery, respectively. Our model has limitations, however, it highlights the economic
burden of arthroplasty in the future in England and Wales as a real
and unaddressed problem. This will have significant implications
for the provision of health care and the management of orthopaedic
services in the future. Cite this article:
Fungal and mycobacterial periprosthetic joint infections (PJI) are rare events. Clinicians are wary of missing these diagnoses, often leading to the routine ordering of fungal and mycobacterial cultures on periprosthetic specimens. Our goal was to examine the utility of these cultures and explore a modern bacterial culture technique using bacterial blood culture bottles (BCBs) as an alternative. We performed a retrospective review of patients diagnosed with hip or knee PJI between 1 January 2010 and 31 December 2019, at the Mayo Clinic in Rochester, Minnesota, USA. We included patients aged 18 years or older who had fungal, mycobacterial, or both cultures performed together with bacterial cultures. Cases with positive fungal or mycobacterial cultures were reviewed using the electronic medical record to classify the microbiological findings as representing true infection or not.Aims
Methods
This study aimed to develop a virtual clinic for the purpose of reducing face-to-face orthopaedic consultations. Anonymized experts (hip and knee arthroplasty patients, surgeons, physiotherapists, radiologists, and arthroplasty practitioners) gave feedback via a Delphi Consensus Technique. This consisted of an iterative sequence of online surveys, during which virtual documents, made up of a patient-reported questionnaire, standardized radiology report, and decision-guiding algorithm, were modified until consensus was achieved. We tested the patient-reported questionnaire on seven patients in orthopaedic clinics using a ‘think-aloud’ process to capture difficulties with its completion.Aims
Patients and Methods
Surgical site infection (SSI) is a common complication of surgery
with an incidence of about 1% in the United Kingdom. Sutures can
lead to the development of a SSI, as micro-organisms can colonize
the suture as it is implanted. Triclosan-coated sutures, being antimicrobical,
were developed to reduce the rate of SSI. Our aim was to assess
whether triclosan-coated sutures cause a reduction in SSIs following
arthroplasty of the hip and knee. This two-arm, parallel, double-blinded study involved 2546 patients
undergoing elective total hip (THA) and total knee arthroplasty
(TKA) at three hospitals. A total of 1323 were quasi-randomized
to a standard suture group, and 1223 being quasi-randomized to the
triclosan-coated suture group. The primary endpoint was the rate
of SSI at 30 days postoperatively.Aims
Patients and Methods
The purpose of this study is to determine if higher volume hospitals
have lower costs in revision hip and knee arthroplasty. We questioned the Centres for Medicare and Medicaid Services
(CMS) Inpatient Charge Data and identified 789 hospitals performing
a total of 29 580 revision arthroplasties in 2014. Centres were
dichotomised into high-volume (performing over 50 revision cases
per year) and low-volume. Mean total hospital-specific charges and
inpatient payments were obtained from the database and stratified
based on Diagnosis Related Group (DRG) codes. Patient satisfaction
scores were obtained from the multiyear CMS Hospital Compare database.Aims
