The number of arthroplasties of the hip and knee
is predicted to increase rapidly during the next 20 years. Accompanying
this is the dilemma of how to follow-up these patients appropriately.
Current guidelines recommend long-term follow-up to identify patients
with aseptic loosening, which can occur more than a decade postoperatively.
The current guidelines and practices of orthopaedic surgeons vary
widely. Existing models take up much clinical time and are expensive.
Pilot studies using ‘virtual’ clinics and advanced-practice physiotherapists
have shown promise in decreasing the time and costs for orthopaedic surgeons
and patients. This review discusses current practices and future trends in
the follow-up of patients who have an arthroplasty. Cite this article:
The purpose of this study was to analyze the incidence of the different ultrasound phenotypes of developmental dysplasia of the hip (DDH), and to determine their subsequent course. A consecutive series of 28 092 neonates was screened and classified according to the Graf method as part of a nationwide surveillance programme, and then followed prospectively. Abnormal hips were followed until they became normal (Graf type I). Type IIb hips and higher grades were treated by abduction in a Tübinger orthosis until normal. Dislocated hips underwent closed or open reduction.Aims
Patients and Methods
The primary aim of this independent prospective randomised trial
was to compare serum metal ion levels for ceramic-on-metal (CoM)
and metal-on-metal (MoM) bearing surfaces in total hip arthroplasty
(THA). Our one-year results demonstrated elevation in metal ion
levels above baseline with no significant difference between the
CoM and MoM groups. This paper reviews the five-year data. The implants used in each patient differed only in respect to
the type of femoral head (ceramic or metal). At five-year follow-up
of the 83 enrolled patients, data from 67 (36 CoM, 31 MoM) was available
for comparison.Aims

The mucopolysaccharidoses (MPS) are a group of
inherited lysosomal storage disorders with clinical manifestations relevant
to the orthopaedic surgeon. Our aim was to review the recent advances
in their management and the implications for surgical practice. The current literature about MPSs is summarised, emphasising
orthopaedic complications and their management. Recent advances in the diagnosis and management of MPSs include
the recognition of slowly progressive, late presenting subtypes,
developments in life-prolonging systemic treatment and potentially
new indications for surgical treatment. The outcomes of surgery
in these patients are not yet validated and some procedures have
a high rate of complications which differ from those in patients
who do not have a MPS. The diagnosis of a MPS should be considered in adolescents or
young adults with a previously unrecognised dysplasia of the hip.
Surgeons treating patients with a MPS should report their experience
and studies should include the assessment of function and quality
of life to guide treatment. Cite this article:
Fractures of the hip are common, often occurring
in frail elderly patients, but also in younger fit healthy patients following
trauma. They have a significant associated mortality and major social
and financial implications to patients and health care providers.
Many guidelines are available for the management of these patients,
mostly recommending early surgery for the best outcomes. As a result,
healthcare authorities now put pressure on surgical teams to ‘fast
track’ patients with a fracture of the hip, often misquoting the
available literature, which in itself can be confusing and even
conflicting. This paper has been written following an extensive review of
the available literature. An attempt is made to clarify what is
meant by early surgery (expeditious Cite this article:
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
The aims of this study were to investigate any possible relationship
between a preoperative sensitivity to pain and the degree of pain
at rest and on exertion with postoperative function in patients
who underwent stemless total shoulder arthroplasty (TSA). In this prospective study, we included 63 patients who underwent
stemless TSA and were available for evaluation one year postoperatively.
There were 31 women and 32 men; their mean age was 71 years (53
to 89). The pain threshold, which was measured using a Pain Matcher
(PM) unit, the degree of pain (visual analogue scale at rest and
on exertion, and function using the short version of the Disabilities
of the Arm, Shoulder and Hand questionnaire (QuickDASH), were recorded
preoperatively, as well as three and 12 months postoperatively.Aims
Patients and Methods
To evaluate interobserver reliability of the Orthopaedic Trauma
Association’s open fracture classification system (OTA-OFC). Patients of any age with a first presentation of an open long
bone fracture were included. Standard radiographs, wound photographs,
and a short clinical description were given to eight orthopaedic
surgeons, who independently evaluated the injury using both the
Gustilo and Anderson (GA) and OTA-OFC classifications. The responses
were compared for variability using Cohen’s kappa.Aims
Patients and Methods
The aim of this study was to identify key pathological genes in osteoarthritis (OA). We searched and downloaded mRNA expression data from the Gene Expression Omnibus database to identify differentially expressed genes (DEGs) of joint synovial tissues from OA and normal individuals. Gene Ontology (GO) and Kyoto Encyclopaedia of Genes and Genomes (KEGG) pathway analyses were used to assess the function of identified DEGs. The protein-protein interaction (PPI) network and transcriptional factors (TFs) regulatory network were used to further explore the function of identified DEGs. The quantitative real-time polymerase chain reaction (qRT-PCR) was applied to validate the result of bioinformatics analysis. Electronic validation was performed to verify the expression of selected DEGs. The diagnosis value of identified DEGs was accessed by receiver operating characteristic (ROC) analysis.Objectives
Methods
Total knee arthroplasty (TKA) is a cost effective
and extremely successful operation. As longevity increases, the demand
for primary TKA will continue to rise. The success and survivorship
of TKAs are dependent on the demographics of the patient, surgical
technique and implant-related factors. Currently the risk of failure of a TKA requiring revision surgery
ten years post-operatively is 5%. The most common indications for revision include aseptic loosening
(29.8%), infection (14.8%), and pain (9.5%). Revision surgery poses
considerable clinical burdens on patients and financial burdens
on healthcare systems. We present a current concepts review on the epidemiology of failed
TKAs using data from worldwide National Joint Registries. Cite this article:
The aim of this study was to determine whether patients with
metal-on-metal (MoM) arthroplasties of the hip have an increased
risk of cardiac failure compared with those with alternative types
of arthroplasties (non-MoM). A linkage study between the National Joint Registry, Hospital
Episodes Statistics and records of the Office for National Statistics
on deaths was undertaken. Patients who underwent elective total
hip arthroplasty between January 2003 and December 2014 with no
past history of cardiac failure were included and stratified as
having either a MoM (n = 53 529) or a non-MoM (n = 482 247) arthroplasty.
The primary outcome measure was the time to an admission to hospital
for cardiac failure or death. Analysis was carried out using data
from all patients and from those matched by propensity score.Aims

Hydroxyapatite coatings for uncemented fixation in total knee
arthroplasty can theoretically provide a long-lasting biological
interface with the host bone. The objective of this study was to
test this hypothesis with propriety hydroxyapatite, peri-apatite,
coated tibial components using component migration measured with radiostereometric
analysis over two years as an indicator of long-term fixation. A total of 29 patients at two centres received uncemented PA-coated
tibial components and were followed for two years with radiostereometric
analysis exams to quantify the migration of the component.Aims
Patients and Methods
The purpose of this study is to determine if higher volume hospitals
have lower costs in revision hip and knee arthroplasty. We questioned the Centres for Medicare and Medicaid Services
(CMS) Inpatient Charge Data and identified 789 hospitals performing
a total of 29 580 revision arthroplasties in 2014. Centres were
dichotomised into high-volume (performing over 50 revision cases
per year) and low-volume. Mean total hospital-specific charges and
inpatient payments were obtained from the database and stratified
based on Diagnosis Related Group (DRG) codes. Patient satisfaction
scores were obtained from the multiyear CMS Hospital Compare database.Aims
