To assess how the cost-effectiveness of total hip arthroplasty (THA) and total knee arthroplasty (TKA) varies with age, sex, and preoperative Oxford Hip or Knee Score (OHS/OKS); and to identify the patient groups for whom THA/TKA is cost-effective. We conducted a cost-effectiveness analysis using a Markov model from a United Kingdom NHS perspective, informed by published analyses of patient-level data. We assessed the cost-effectiveness of THA and TKA in adults with hip or knee osteoarthritis compared with having no arthroplasty surgery during the ten-year time horizon.Aims
Methods
The aim of this study was to assess the effect of multimorbidity
on improvements in health-related quality of life (HRQoL) following
total hip arthroplasty (THA) and total knee arthroplasty (TKA). Using data from a regional joint registry for 14 573 patients,
HRQoL was measured prior and one year following surgery using the
Oxford Hip Score (OHS) and Oxford Knee Score (OKS), and the 12-Item
Short-Form Health Survey Physical and Mental Component Summary scores
(PCS and MCS, respectively). Multimorbidity was defined as the concurrence
of two or more self-reported chronic conditions. A linear mixed-effects
model was used to test the effects of multimorbidity and the number
of chronic conditions on improvements in HRQoL.Aims
Patients and Methods
If patients could recall their physical status
before total hip (THA) or knee arthroplasty (TKA) accurately it
could have valuable applications both clinically and for research.
This study evaluated the accuracy of a patient’s recollection one
year after either THA or TKA using the Oxford hip or knee scores
(OHS and OKS). In total, 113 patients (59 THA, 54 TKA) who had completed
the appropriate score pre-operatively were asked to complete the
score again at a mean of 12.4 months (standard deviation ( While there were no significant differences between the actual
and recalled pre-operative scores (OHS mean difference 0.8, A patient’s recollection of pre-operative pain and function is
inaccurate one year after THA or TKA. Cite this article:
