For the increasing number of working-age patients undergoing total hip or total knee arthroplasty (THA/TKA), return to work (RTW) after surgery is crucial. We investigated the association between occupational class and time to RTW after THA or TKA. Data from the prospective multicentre Longitudinal Leiden Orthopaedics Outcomes of Osteoarthritis Study were used. Questionnaires were completed preoperatively and six and 12 months postoperatively. Time to RTW was defined as days from surgery until RTW (full or partial). Occupational class was preoperatively assessed and categorized into four categories according to the International Standard Classification of Occupations 2008 (blue-/white-collar, high-/low-skilled). Cox regression analyses were conducted separately for THA and TKA patients. Low-skilled blue-collar work was used as the reference category.Aims
Methods
The Unified Classification System (UCS) was introduced
because of a growing need to have a standardised universal classification
system of periprosthetic fractures. It combines and simplifies many
existing classification systems, and can be applied to any fracture
around any partial or total joint replacement occurring during or
after operation. Our goal was to assess the inter- and intra-observer
reliability of the UCS in association with
We obtained information from the Elective Orthopaedic
Centre on 1523 patients with baseline and six-month Oxford hip scores
(OHS) after undergoing primary hip replacement (THR) and 1784 patients
with Oxford knee scores (OKS) for primary knee replacement (TKR)
who completed a six-month satisfaction questionnaire. Receiver operating characteristic curves identified an absolute
change in OHS of 14 points or more as the point that discriminates
best between patients’ satisfaction levels and an 11-point change
for the OKS. Satisfaction is highest (97.6%) in patients with an
absolute change in OHS of 14 points or more, compared with lower
levels of satisfaction (81.8%) below this threshold. Similarly,
an 11-point absolute change in OKS was associated with 95.4% satisfaction
compared with 76.5% below this threshold. For the six-month OHS
a score of 35 points or more distinguished patients with the highest
satisfaction level, and for the six-month OKS 30 points or more identified
the highest level of satisfaction. The thresholds varied according
to patients’ pre-operative score, where those with severe pre-operative
pain/function required a lower six-month score to achieve the highest
levels of satisfaction. Our data suggest that the choice of a six-month follow-up to
assess patient-reported outcomes of THR/TKR is acceptable. The thresholds
help to differentiate between patients with different levels of
satisfaction, but external validation will be required prior to
general implementation in clinical practice.

A total of 763,213 hip and knee joint arthroplasty episodes recorded in the National Joint Registry for England and Wales (NJR) and 105,407 episodes from the Norwegian Arthroplasty Register were used to model individual mortality risk over the first year after surgery using flexible parametric survival regression. Results. The one-year mortality rates in the NJR were 10.8 and 8.9 per 1,000 patient-years after hip and
