The Oxford hip score (OHS) is a 12-item questionnaire designed
and developed to assess function and pain from the perspective of
patients who are undergoing total hip replacement (THR). The OHS
has been shown to be consistent, reliable, valid and sensitive to
clinical change following THR. It has been translated into different
languages, but no adequately translated, adapted and validated Danish
language version exists. The OHS was translated and cross-culturally adapted into Danish
from the original English version, using methods based on best-practice
guidelines. The translation was tested for psychometric quality
in patients drawn from a cohort from the Danish Hip Arthroplasty
Register (DHR).Objectives
Methods
The influence of metabolic syndrome (MetS) on the outcome after hip and knee arthroplasty is debated. We aimed to investigate the change in patient-reported outcome measure (PROM) scores after hip and knee arthroplasty, comparing patients with and without MetS. From 1 May 2017 to 30 November 2019, a prospective cohort of 2,586 patients undergoing elective unilateral hip and knee arthroplasty was established in Denmark. Data from national registries and a local database were used to determine the presence of MetS. Patients’ scores on Oxford Hip Score (OHS) or Oxford Knee Score (OKS), EuroQol five-dimension five-level questionnaire (EQ-5D-5L), University of California, Los Angeles (UCLA) Activity Scale, and Forgotten Joint Score (FJS) at baseline, three, 12, and 24 months after surgery were collected. Primary outcome was the difference between groups from baseline to 12 months in OHS and OKS. Secondary outcomes were scores of OHS and OKS at three and 24 months and EQ-5D-5L, UCLA Activity Scale, and FJS at three, 12, and 24 months after surgery. Generalized linear mixed model was applied, adjusting for age, sex, Charlson Comorbidity Index, and smoking to present marginal mean and associated 95% CIs.Aims
Methods
We examined the one-year risk of symptomatic
venous thromboembolism (VTE) following primary total hip replacement
(THR) among Danish patients and a comparison cohort from the general
population. From the Danish Hip Arthroplasty Registry we identified
all primary THRs performed in Denmark between 1995 and 2010 (n =
85 965). In all, 97% of patients undergoing THR received low-molecular-weight
heparin products during hospitalisation. Through the Danish Civil
Registration System we sampled a comparison cohort who had not undergone
THR from the general population (n = 257 895). Among the patients
undergoing THR, the risk of symptomatic VTE was 0.79% between 0
and 90 days after surgery and 0.29% between 91 and 365 days after
surgery. In the comparison cohort the corresponding risks were 0.05%
and 0.12%, respectively. The adjusted relative risks of symptomatic
VTE among patients undergoing THR were 15.84 (95% confidence interval
(CI) 13.12 to 19.12) during the first 90 days after surgery and
2.41 (95% CI 2.04 to 2.85) during 91 to 365 days after surgery,
compared with the comparison cohort. The relative risk of VTE was
elevated irrespective of the gender, age and level of comorbidity
at the time of THR. We concluded that THR was associated with an increased risk of
symptomatic VTE up to one year after surgery compared with the general
population, although the absolute risk is small.
