The aim of this study was to report our experience at 3.5 years with outpatient total hip arthroplasty (THA). In this prospective cohort study, we included all patients who were planned to receive primary THA through the anterior approach between 1 April 2014 and 1 October 2017. Patient-related data and surgical information were recorded. Patient reported outcome measures (PROMs) related to the hip and an anchor question were taken preoperatively, at six weeks, three months, and one year after surgery. All complications, readmissions, and reoperations were registered.Aims
Methods
Only limited data are available regarding the
infiltration of local anaesthetic for total hip arthroplasty (THA),
and no studies were performed for THA using the anterior approach. In this prospective, randomised placebo-controlled study we investigated
the effect of both standard and reverse infiltration of local anaesthetic
in combination with the anterior approach for THA. The primary endpoint
was the mean numeric rating score for pain four hours post-operatively.
In addition, we recorded the length of hospital stay, the operating
time, the destination of the patient at discharge, the use of pain
medication, the occurrence of side effects and pain scores at various
times post-operatively. Between November 2012 and January 2014, 75 patients were included
in the study. They were randomised into three groups: standard infiltration
of local anaesthetic, reversed infiltration of local anaesthetic,
and placebo. There was no difference in mean numeric rating score
for pain four hours post-operatively (p = 0.87). There were significantly
more side effects at one and eight hours post-operatively in the
placebo group (p = 0.02; p = 0.03), but this did not influence the
mobilisation of the patients. There were no differences in all other
outcomes between the groups. We found no clinically relevant effect when the infiltration
of local anaesthetic with ropivacaine and epinephrine was used in
a multimodal pain protocol for THA using the anterior approach. 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%
confidence intervals (CI) 1.72 to 3.51; p <
0.001), living situation
