Aims. Medial unicompartmental knee arthroplasty (mUKA) is an advised treatment for anteromedial knee osteoarthritis. While long-term survival after mUKA is well described, reported incidences of short-term surgical complications vary and the effect of surgical usage on complications is less established. We aimed to describe the overall occurrence and treatment of surgical complications within 90 days of mUKA, as well as occurrence in high-usage centres compared to low-usage centres. Methods. mUKAs performed in eight
Aims. The aim of this prospective multicentre study was to describe trends in length of stay and early complications and readmissions following unicompartmental knee arthroplasty (UKA) performed at eight different centres in Denmark using a
Bilateral simultaneous total knee replacement (TKR) has been considered by some to be associated with increased morbidity and mortality. Our study analysed the outcome of 150 consecutive, but selected, bilateral simultaneous TKRs and compared them with that of 271 unilateral TKRs in a standardised
Day-case success rates after primary total hip arthroplasty (THA), total knee arthroplasty (TKA), and medial unicompartmental knee arthroplasty (mUKA) may vary, and detailed data are needed on causes of not being discharged. The aim of this study was to analyze the association between surgical procedure type and successful day-case surgery, and to analyze causes of not being discharged on the day of surgery when eligible and scheduled for day-case THA, TKA, and mUKA. A multicentre, prospective consecutive cohort study was carried out from September 2022 to August 2023. Patients were screened for day-case eligibility using well defined inclusion and exclusion criteria, and discharged when fulfilling predetermined discharge criteria. Day-case eligible patients were scheduled for surgery with intended start of surgery before 1.00 pm.Aims

Aims. To investigate the impact of consecutive perioperative care transitions on in-hospital recovery of patients who had primary total knee arthroplasty (TKA) over an 11-year period. Methods. This observational cohort study used electronic health record data from all patients undergoing preoperative screening for primary TKA at a Northern Netherlands hospital between 2009 and 2020. In this timeframe, three perioperative care transitions were divided into four periods: Baseline care (Joint Care, n = 171; May 2009 to August 2010), Function-tailored (n = 404; September 2010 to October 2013),
We present detailed information about early morbidity
after aseptic revision knee replacement from a nationwide study.
All aseptic revision knee replacements undertaken between 1st October
2009 and 30th September 2011 were analysed using the Danish National
Patient Registry with additional information from the Danish Knee
Arthroplasty Registry. The 1218 revisions involving 1165 patients
were subdivided into total revisions, large partial revisions, partial
revisions and revisions of unicondylar replacements (UKR revisions).
The mean age was 65.0 years (27 to 94) and the median length of
hospital stay was four days (interquartile range: 3 to 5), with
a 90 days re-admission rate of 9.9%,
re-operation rate of 3.5% and mortality rate of 0.2%. The age ranges
of 51 to 55 years (p = 0.018), 76 to 80 years (p <
0.001) and ≥ 81
years (p <
0.001) were related to an increased risk of re-admission.
The age ranges of 76 to 80 years (p = 0.018) and the large partial
revision subgroup (p = 0.073) were related to an increased risk
of re-operation. The ages from 76 to 80 years (p <
0.001), age ≥ 81
years (p <
0.001) and surgical time >
120 min (p <
0.001)
were related to increased length of hospital stay, whereas the use
of a tourniquet (p = 0.008) and surgery in a low volume centre (p
= 0.013) were related to shorter length of stay. In conclusion, we found a similar incidence of early post-operative
morbidity after aseptic knee revisions as has been reported after
primary procedures. This suggests that a length of hospital stay ≤ four
days and discharge home at that time is safe following aseptic knee
revision surgery in Denmark. Cite this article:
After implementation of a ‘fast-track’ rehabilitation
protocol in our hospital, mean length of hospital stay for primary
total hip arthroplasty decreased from 4.6 to 2.9 nights for unselected
patients. However, despite this reduction there was still a wide
range across the patients’ hospital duration. The purpose of this
study was to identify which specific patient characteristics influence
length of stay after successful implementation of a ‘fast-track’
rehabilitation protocol. A total of 477 patients (317 female and
160 male, mean age 71.0 years; 39.3 to 92.6, mean BMI 27.0 kg/m2;18.8
to 45.2) who underwent primary total hip arthroplasty between 1
February 2011 and 31 January 2013, were included in this retrospective
cohort study. A length of stay greater than the median was considered
as an increased duration. Logistic regression analyses were performed
to identify potential factors associated with increased durations.
Median length of stay was two nights (interquartile range 1), and
the mean length of stay 2.9 nights (1 to 75). In all, 266 patients
had a length of stay ≤ two nights. Age (odds ratio (OR) 2.46; 95%

The primary aim of this study was to investigate the effect of
an enhanced recovery program (ERP) on the short-term functional
outcome after total hip arthroplasty (THA). Secondary outcomes included
its effect on rates of dislocation and mortality. Data were gathered on 1161 patients undergoing primary THA which
included 611 patients treated with traditional rehabilitation and
550 treated with an ERP. Aims
Patients and Methods
Data on early morbidity and complications after
revision total hip replacement (THR) are limited. The aim of this nationwide
study was to describe and quantify early morbidity after aseptic
revision THR and relate the morbidity to the extent of the revision
surgical procedure. We analysed all aseptic revision THRs from 1st
October 2009 to 30th September 2011 using the Danish National Patient
Registry, with additional information from the Danish Hip Arthroplasty
Registry. There were 1553 procedures (1490 patients) performed in
40 centres and we divided them into total revisions, acetabular
component revisions, femoral stem revisions and partial revisions.
The mean age of the patients was 70.4 years (25 to 98) and the median
hospital stay was five days (interquartile range 3 to 7). Within 90
days of surgery, the readmission rate was 18.3%, mortality rate
1.4%, re-operation rate 6.1%, dislocation rate 7.0% and infection
rate 3.0%. There were no differences in these outcomes between high-
and low-volume centres. Of all readmissions, 255 (63.9%) were due
to ‘surgical’ complications Cite this article:
The outcome after total hip replacement has improved
with the development of surgical techniques, better pain management
and the introduction of enhanced recovery pathways. These pathways
require a multidisciplinary team to manage pre-operative education,
multimodal pain control and accelerated rehabilitation. The current economic
climate and restricted budgets favour brief hospitalisation while
minimising costs. This has put considerable pressure on hospitals
to combine excellent results, early functional recovery and shorter
admissions. In this review we present an evidence-based summary of some common
interventions and methods, including pre-operative patient education,
pre-emptive analgesia, local infiltration analgesia, pre-operative
nutrition, the use of pulsed electromagnetic fields, peri-operative
rehabilitation, wound dressings, different surgical techniques, minimally
invasive surgery and

The rate of day-case total knee arthroplasty (TKA) in the UK is currently approximately 0.5%. Reducing length of stay allows orthopaedic providers to improve efficiency, increase operative throughput, and tackle the rising demand for joint arthroplasty surgery and the COVID-19-related backlog. Here, we report safe delivery of day-case TKA in an NHS trust via inpatient wards with no additional resources. Day-case TKAs, defined as patients discharged on the same calendar day as surgery, were retrospectively reviewed with a minimum follow-up of six months. Analysis of hospital and primary care records was performed to determine readmission and reattendance rates. Telephone interviews were conducted to determine patient satisfaction.Aims

In the Netherlands, general practitioners (GPs) can request radiographs. After a radiologically diagnosed fracture, patients are immediately referred to the emergency department (ED). Since 2020, the Máxima Medical Centre has implemented a new care pathway for minor trauma patients, referring them immediately to the traumatology outpatient clinic (OC) instead of the ED. We investigated whether this altered care pathway leads to a reduction in healthcare consumption and concomitant costs. In this retrospective cohort study, patients were included if a radiologist diagnosed a fracture on a radiograph requested by the GP from August to October 2019 (control group) or August to October 2020 (research group), on weekdays between 8.30 am and 4.00 pm. The study compared various outcomes between groups, including the length of the initial hospital visit, frequency of hospital visits and medical procedures, extent of imaging, and healthcare expenses.Aims
Methods
The aim of this meta-analysis was to determine the pooled incidence of postoperative urinary retention (POUR) following total hip and knee arthroplasty (total joint replacement (TJR)) and to evaluate the risk factors and complications associated with POUR. Two authors conducted searches in PubMed, Embase, Web of Science, and Scopus on TJR and urinary retention. Eligible studies that reported the rate of POUR and associated risk factors for patients undergoing TJR were included in the analysis. Patient demographic details, medical comorbidities, and postoperative outcomes and complications were separately analyzed. The effect estimates for continuous and categorical data were reported as standardized mean differences (SMDs) and odds ratios (ORs) with 95% CIs, respectively.Aims
Methods
The primary aim of this study was to compare the migration of the femoral and tibial components of the cementless rotating platform Attune and Low Contact Stress (LCS) total knee arthroplasty (TKA) designs, two years postoperatively, using radiostereometric analysis (RSA) in order to assess the risk of the development of aseptic loosening. A secondary aim was to compare clinical and patient-reported outcome measures (PROMs) between the designs. A total of 61 TKAs were analyzed in this randomized clinical RSA trial. RSA examinations were performed one day and three, six, 12, and 24 months postoperatively. The maximal total point motion (MPTM), translations, and rotations of the components were analyzed. PROMs and clinical data were collected preoperatively and at six weeks and three, six, 12, and 24 months postoperatively. Linear mixed effect modelling was used for statistical analyses.Aims

Waiting times for arthroplasty surgery in Northern Ireland are among the longest in the NHS, which have been further lengthened by the onset of the COVID-19 global pandemic in March 2020. The Department of Health in Northern Ireland has announced a new Elective Care Framework (ECF), with the framework proposing that by March 2026 no patient will wait more than 52 weeks for inpatient/day case treatment. We aimed to assess the feasibility of achieving this with reference to total hip arthroplasty (THA) and total knee arthroplasty (TKA). Mathematical modelling was undertaken to calculate when the ECF targets will be achieved for THA and TKA, as well as the time when waiting lists for THA and TKA will be cleared. The number of patients currently on the waiting list and percentage operating capacity relative to pre-COVID-19 capacity was used to determine future projections.Aims
