Aims. The purpose of this study was to determine the association between prior sleeve gastrectomy in patients undergoing primary total hip and knee arthroplasty, and 90-day complications, incidence of revision arthroplasty, and patient-reported outcome scores at final follow-up. Methods. This is a retrospective, single-centre analysis. Patients undergoing primary hip or knee arthroplasty with a prior sleeve gastrectomy were eligible for inclusion (n = 80 patients). A
This study aimed to investigate the estimated change in primary and revision arthroplasty rate in the Netherlands and Denmark for hips, knees, and shoulders during the COVID-19 pandemic in 2020 (COVID-period). Additional points of focus included the comparison of patient characteristics and hospital type (2019 vs COVID-period), and the estimated loss of quality-adjusted life years (QALYs) and impact on waiting lists. All hip, knee, and shoulder arthroplasties (2014 to 2020) from the Dutch Arthroplasty Register, and hip and knee arthroplasties from the Danish Hip and Knee Arthroplasty Registries, were included. The expected number of arthroplasties per month in 2020 was estimated using Poisson regression, taking into account changes in age and sex distribution of the general Dutch/Danish population over time, calculating observed/expected (O/E) ratios. Country-specific proportions of patient characteristics and hospital type were calculated per indication category (osteoarthritis/other elective/acute). Waiting list outcomes including QALYs were estimated by modelling virtual waiting lists including 0%, 5% and 10% extra capacity.Aims
Methods
Aims. We studied the outcomes of hip and knee arthroplasties in a high-volume arthroplasty centre to determine if patients with
Wound complications are reported in up to 10% hip and knee arthroplasties and there is a proven association between wound complications and deep prosthetic infections. In this randomised controlled trial (RCT) we explore the potential benefits of a portable, single use, incisional negative pressure wound therapy dressing (iNPWTd) on wound exudate, length of stay (LOS), wound complications, dressing changes and cost-effectiveness following total hip and knee arthroplasties. A total of 220 patients undergoing elective primary total hip and knee arthroplasties were recruited into in a non-blinded RCT. For the final analysis there were 102 patients in the study group and 107 in the control group.Objectives
Methods
This study evaluated whether obese patients who
lost weight before their total joint replacement and kept it off post-operatively
were at lower risk of surgical site infection (SSI) and re-admission
compared with those who remained the same weight. We reviewed 444 patients who underwent a total hip replacement
and 937 with a total knee replacement who lost weight pre-operatively
and sustained their weight loss after surgery. After adjustments,
patients who lost weight before a total hip replacement and kept
it off post-operatively had a 3.77 (95% confidence interval (CI)
1.59 to 8.95) greater likelihood of deep SSIs and those who lost
weight before a total knee replacement had a 1.63 (95% CI 1.16 to
2.28) greater likelihood of re-admission compared with the reference
group. These findings raise questions about the safety of weight management
before total replacement of the hip and knee joints. Cite this article:
We performed a meta-analysis of modern total
joint replacement (TJR) to determine the post-operative mortality and
the cause of death using different thromboprophylactic regimens
as follows: 1) no routine chemothromboprophylaxis (NRC); 2) Potent
anticoagulation (PA) (unfractionated or low-molecular-weight heparin, ximelagatran,
fondaparinux or rivaroxaban); 3) Potent anticoagulation combined
(PAC) with regional anaesthesia and/or pneumatic compression devices
(PCDs); 4) Warfarin (W); 5) Warfarin combined (WAC) with regional anaesthesia
and/or PCD; and 6) Multimodal (MM) prophylaxis, including regional
anaesthesia, PCDs and aspirin in low-risk patients. Cause of death
was classified as autopsy proven, clinically certain or unknown.
Deaths were grouped into cardiopulmonary excluding pulmonary embolism
(PE), PE, bleeding-related, gastrointestinal, central nervous system,
and others (miscellaneous). Meta-analysis based on fixed effects
or random effects models was used for pooling incidence data. In all, 70 studies were included (99 441 patients; 373 deaths).
The mortality was lowest in the MM (0.2%) and WC (0.2%) groups.
The most frequent cause of death was cardiopulmonary (47.9%), followed
by PE (25.4%) and bleeding (8.9%). The proportion of deaths due
to PE was not significantly affected by the thromboprophylaxis regimen (PA, 35.5%;
PAC, 28%; MM, 23.2%; and NRC, 16.3%). Fatal bleeding was higher
in groups relying on the use of anticoagulation (W, 33.8%; PA, 9.4%;
PAC, 10.8%) but the differences were not statistically significant. Our study demonstrated that the routine use of PA does not reduce
the overall mortality or the proportion of deaths due to PE.
We audited the relationship between obesity and the age at which hip and knee replacement was undertaken at our centre. The database was analysed for age, the Oxford hip or knee score and the body mass index (BMI) at the time of surgery. In total, 1369 patients were studied, 1025 treated by hip replacement and 344 by knee replacement. The patients were divided into five groups based on their BMI (normal, overweight, moderately obese, severely
