The purpose of this study was to compare symptomatic treatment
of a fracture of the base of the fifth metatarsal with immobilisation
in a cast. Our null hypothesis was that immobilisation gave better patient
reported outcome measures (PROMs). The alternative hypothesis was
that symptomatic treatment was not inferior. A total of 60 patients were randomised to receive four weeks
of treatment, 36 in a double elasticated bandage (symptomatic treatment
group) and 24 in a below-knee walking cast (immobilisation group).
The primary outcome measure used was the validated Visual Analogue
Scale Foot and Ankle (VAS-FA) Score. Data were analysed by a clinician,
blinded to the form of treatment, at presentation and at four weeks,
three months and six months after injury. Loss to follow-up was
43% at six months. Multiple imputations missing data analysis was performed.Aims
Patients and Methods
Tranexamic acid (TXA) is an antifibrinolytic agent used as a blood-sparing technique in total knee arthroplasty (TKA), and is routinely administered by intravenous (IV) or intra-articular (IA) injection. Recently, a novel method of TXA administration, the combined IV and IA application of TXA, has been applied in TKA. However, the scientific evidence of combined administration of TXA in TKA is still meagre. This meta-analysis aimed to investigate the efficacy and safety of combined IV and IA TXA in patients undergoing TKA. A systematic search was carried out in PubMed, the Cochrane Clinical Trial Register (Issue12 2015), Embase, Web of Science and the Chinese Biomedical Database. Only randomised controlled trials (RCT) evaluating the efficacy and safety of combined use TXA in TKA were identified. Two authors independently identified the eligible studies, extracted data and assessed the methodological quality of included studies. Meta-analysis was conducted using Review Manager 5.3 software.Objectives
Materials and Methods
Patient-reported outcome measures (PROMs) are often used to evaluate the outcome of treatment in patients with distal radial fractures. Which PROM to select is often based on assessment of measurement properties, such as validity and reliability. Measurement properties are assessed in clinimetric studies, and results are often reviewed without considering the methodological quality of these studies. Our aim was to systematically review the methodological quality of clinimetric studies that evaluated measurement properties of PROMs used in patients with distal radial fractures, and to make recommendations for the selection of PROMs based on the level of evidence of each individual measurement property. A systematic literature search was performed in PubMed, EMbase, CINAHL and PsycINFO databases to identify relevant clinimetric studies. Two reviewers independently assessed the methodological quality of the studies on measurement properties, using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. Level of evidence (strong / moderate / limited / lacking) for each measurement property per PROM was determined by combining the methodological quality and the results of the different clinimetric studies.Objectives
Methods
We aimed to assess the comparability of data in joint replacement
registries and identify ways of improving the comparisons between
registries and the overall monitoring of joint replacement surgery. We conducted a review of registries that are full members of
the International Society of Arthroplasty Registries with publicly
available annual reports in English. Of the six registries which
were included, we compared the reporting of: mean age, definitions
for revision and re-operation, reasons for revision, the approach
to analysing revisions, and patient-reported outcome measures (PROMs)
for primary and revision total hip arthroplasty (THA) and hip resurfacing
arthroplasty (HRA).Aims
Materials and Methods
This review summarises the evidence for the treatment
of displaced fractures of the femoral neck in elderly patients.
Results from randomised clinical trials and national register studies are
presented when available. The advantages of arthroplasty compared with internal fixation
are supported by several studies. A number of studies contribute
to the discussions of total hip arthroplasty (THA) The direct lateral approach reduces the risk of dislocation compared
with the posterior approach. Cemented implants lower the risk of
periprosthetic fracture and its subsequent morbidity and mortality.
As the risk of peri-operative death related to bone cement can be reduced
by adequate measures, cemented implants are recommended in fracture
cases. Take home message: There remains a great variation in the surgical
management of patients with a hip fracture, and an evidence-based
approach should improve the outcomes for this vulnerable patient
group. Cite this article:
To assess the responsiveness and ceiling/floor effects of the Forgotten Joint Score -12 and to compare these with that of the more widely used Oxford Hip Score (OHS) in patients six and 12 months after primary total hip arthroplasty. We prospectively collected data at six and 12 months following total hip arthroplasty from 193 patients undergoing surgery at a single centre. Ceiling effects are outlined with frequencies for patients obtaining the lowest or highest possible score. Change over time from six months to 12 months post-surgery is reported as effect size (Cohen’s d).Objectives
Methods
We performed a systematic review of the literature
pertaining to the functional outcomes of the surgical management
of acetabular fractures. A total of 69 articles met our inclusion
criteria, revealing that eight generic outcome instruments were
used, along with five specific instruments. The majority of studies
reported outcomes using a version of the d’Aubigne and Postel score,
which has not been validated for use in acetabular fracture. Few validated
outcome measures were reported. No psychometric testing of outcome
instruments was performed. The current assessment of outcomes in
surgery for acetabular fractures lacks scientific rigour, and does
not give reliable outcome data for either scientific comparison
or patient counselling. Take home message: The use of non-validated functional outcome
measures is a major limitation of the current literature pertaining
to surgical management of acetabular fractures; future studies should
use validated outcome measures to ensure the legitimacy of the reported
results. Cite this article:
The primary aim of this study was to investigate the effect of
an enhanced recovery program (ERP) on the short-term functional
outcome after total hip arthroplasty (THA). Secondary outcomes included
its effect on rates of dislocation and mortality. Data were gathered on 1161 patients undergoing primary THA which
included 611 patients treated with traditional rehabilitation and
550 treated with an ERP. Aims
Patients and Methods
Oxidised zirconium was introduced as a material for femoral components
in total knee arthroplasty (TKA) as an attempt to reduce polyethylene
wear. However, the long-term survival of this component is not known. We performed a retrospective review of a prospectively collected
database to assess the ten year survival and clinical and radiological
outcomes of an oxidised zirconium total knee arthroplasty with the
Genesis II prosthesis. The Western Ontario and McMaster Universities Osteoarthritis
Index (WOMAC), Knee Injury and Osteoarthritis Outcome Score (KOOS)
and a patient satisfaction scale were used to assess outcome.Aims

The global economy has been facing a financial crisis. Healthcare costs are spiraling, and there is a projected £30 billion health funding gap by 2020 in the UK. What is happening in the UK is a reflection of a global problem. Rationing of healthcare is a topic of much discussion; as unless spending is capped, providing healthcare will become unsustainable. Who decides how money is spent, and which services should be rationed? In this article we aim to discuss the impact that rationing may have on orthopaedic surgery, and we will discuss our own experiences of attempts to ration local services.
There is a large amount of evidence available
about the relative merits of unicompartmental and total knee arthroplasty
(UKA and TKA). Based on the same evidence, different people draw
different conclusions and as a result, there is great variability
in the usage of UKA. The revision rate of UKA is much higher than TKA and so some
surgeons conclude that UKA should not be performed. Other surgeons
believe that the main reason for the high revision rate is that
UKA is easy to revise and, therefore, the threshold for revision
is low. They also believe that UKA has many advantages over TKA
such as a faster recovery, lower morbidity and mortality and better
function. They therefore conclude that UKA should be undertaken
whenever appropriate. The solution to this argument is to minimise the revision rate
of UKA, thereby addressing the main disadvantage of UKA. The evidence
suggests that this will be achieved if surgeons use UKA for at least
20% of their knee arthroplasties and use implants that are appropriate
for these broad indications. Cite this article:
Controversy remains whether the contralateral
hip should be fixed in patients presenting with unilateral slipped capital
femoral epiphysis (SCFE). This retrospective study compares the
outcomes and cost of those patients who had prophylactic fixation
with those who did not. Between January 2000 and December 2010 a total of 50 patients
underwent unilateral fixation and 36 had prophylactic fixation of
the contralateral hip. There were 54 males and 32 females with a
mean age of 12.3 years (9 to 16). The rate of a subsequent slip
without prophylactic fixation was 46%. The risk of complications
was greater, the generic health measures (Short Form-12 physical
(p <
0.001) and mental (p = 0.004) summary scores) were worse.
Radiographic cam lesions in patients presenting with unilateral
SCFE were only seen in patients who did not have prophylactic fixation.
Furthermore, prophylactic fixation of the contralateral hip was
found to be a cost-effective procedure, with a cost per quality
adjusted life year gained of £1431 at the time of last follow-up. Prophylactic fixation of the contralateral hip is a cost-effective
operation that limits the morbidity from the complications of a
further slip, and the diminished functional outcome associated with
unilateral fixation. Cite this article:
Patients who have limb amputation for musculoskeletal
tumours are a rare group of cancer survivors. This was a prospective
cross-sectional survey of patients from five specialist centres
for sarcoma surgery in England. Physical function, pain and quality
of life (QOL) outcomes were collected after lower extremity amputation
for bone or soft-tissue tumours to evaluate the survivorship experience
and inform service provision. Of 250 patients, 105 (42%) responded between September 2012 and
June 2013. From these, completed questionnaires were received from
100 patients with a mean age of 53.6 years (19 to 91). In total
60 (62%) were male and 37 (38%) were female (three not specified).
The diagnosis was primary bone sarcoma in 63 and soft-tissue tumour
in 37. A total of 20 tumours were located in the hip or pelvis,
31 above the knee, 32 between the knee and ankle and 17 in the ankle
or foot. In total 22 had hemipelvectomy, nine hip disarticulation,
35 transfemoral amputation, one knee disarticulation, 30 transtibial
amputation, two toe amputations and one rotationplasty. The Toronto
Extremity Salvage Score (TESS) differed by amputation level, with
poorer scores at higher levels (p <
0.001). Many reported significant
pain. In addition, TESS was negatively associated with increasing
age, and pain interference scores. QOL for Cancer Survivors was
significantly correlated with TESS (p <
0.001). This relationship appeared
driven by pain interference scores. This unprecedented national survey confirms amputation level
is linked to physical function, but not QOL or pain measures. Pain
and physical function significantly impact on QOL. These results
are helpful in managing the expectations of patients about treatment
and addressing their complex needs. Cite this article:
Patient function after arthroplasty should ideally quickly improve.
It is not known which peri-operative function assessments predict
length of stay (LOS) and short-term functional recovery. The objective
of this study was to identify peri-operative functions assessments
predictive of hospital LOS and short-term function after hospital discharge
in hip or knee arthroplasty patients. In total, 108 patients were assessed peri-operatively with the
timed-up-and-go (TUG), Iowa level of assistance scale, post-operative
quality of recovery scale, readiness for hospital discharge scale,
and the Western Ontario and McMaster Osteoarthritis Index (WOMAC).
The older Americans resources and services activities of daily living
(ADL) questionnaire (OARS) was used to assess function two weeks
after discharge. Objectives

The Oxford Hip and Knee Scores (OHS, OKS) have been demonstrated
to vary according to age and gender, making it difficult to compare
results in cohorts with different demographics. The aim of this
paper was to calculate reference values for different patient groups
and highlight the concept of normative reference data to contextualise an
individual’s outcome. We accessed prospectively collected OHS and OKS data for patients
undergoing lower limb joint arthroplasty at a single orthopaedic
teaching hospital during a five-year period.
T-scores were calculated based on the OHS and OKS distributions. Objectives
Methods
There is little evidence on the cost effectiveness
of different brands of hip prostheses. We compared lifetime cost effectiveness
of frequently used brands within types of prosthesis including cemented
(Exeter V40 Contemporary, Exeter V40 Duration and Exeter V40 Elite
Plus Ogee), cementless (Corail Pinnacle, Accolade Trident, and Taperloc Exceed)
and hybrid (Exeter V40 Trilogy, Exeter V40 Trident, and CPT Trilogy).
We used data from three linked English national databases to estimate
the lifetime risk of revision, quality-adjusted life years (QALYs)
and cost. For women with osteoarthritis aged 70 years, the Exeter V40 Elite
Plus Ogee had the lowest risk of revision (5.9% revision risk, 9.0
QALYs) and the CPT Trilogy had the highest QALYs (10.9% revision
risk, 9.3 QALYs). Compared with the Corail Pinnacle (9.3% revision
risk, 9.22 QALYs), the most commonly used brand, and assuming a
willingness-to-pay of £20 000 per QALY gain, the CPT Trilogy is
most cost effective, with an incremental net monetary benefit of £876.
Differences in cost effectiveness between the hybrid CPT Trilogy
and Exeter V40 Trident and the cementless Corail Pinnacle and Taperloc
Exceed were small, and a cautious interpretation is required, given
the limitations of the available information. However, it is unlikely that cemented brands are among the most
cost effective. Similar patterns of results were observed for men
and other ages. The gain in quality of life after total hip arthroplasty,
rather than the risk of revision, was the main driver of cost effectiveness. Cite this article:

This study demonstrates a significant correlation
between the American Knee Society (AKS) Clinical Rating System and
the Oxford Knee Score (OKS) and provides a validated prediction
tool to estimate score conversion. A total of 1022 patients were prospectively clinically assessed
five years after TKR and completed AKS assessments and an OKS questionnaire.
Multivariate regression analysis demonstrated significant correlations between
OKS and the AKS knee and function scores but a stronger correlation
(r = 0.68, p <
0.001) when using the sum of the AKS knee and
function scores. Addition of body mass index and age (other statistically
significant predictors of OKS) to the algorithm did not significantly
increase the predictive value. The simple regression model was used to predict the OKS in a
group of 236 patients who were clinically assessed nine to ten years
after TKR using the AKS system. The predicted OKS was compared with
actual OKS in the second group. Intra-class correlation demonstrated
excellent reliability (r = 0.81, 95% confidence intervals 0.75 to
0.85) for the combined knee and function score when used to predict
OKS. Our findings will facilitate comparison of outcome data from
studies and registries using either the OKS or the AKS scores and
may also be of value for those undertaking meta-analyses and systematic
reviews. Cite this article:
Total knee replacement (TKR) smart tibial trials
have load-bearing sensors which will show quantitative compartment
pressure values and femoral-tibial tracking patterns. Without smart
trials, surgeons rely on feel and visual estimation of imbalance
to determine if the knee is optimally balanced. Corrective soft-tissue
releases are performed with minimal feedback as to what and how
much should be released. The smart tibial trials demonstrate graphically
where and how much imbalance is present, so that incremental releases
can be performed. The smart tibial trials now also incorporate accelerometers
which demonstrate the axial alignment. This now allows the surgeon
the option to perform a slight recut of the tibia or femur to provide
soft-tissue balance without performing soft-tissue releases. Using
a smart tibial trial to assist with soft-tissue releases or bone
re-cuts, improved patient outcomes have been demonstrated at one
year in a multicentre study of 135 patients (135 knees). Cite this article:
