Aims. The purpose of this study was to determine the access to and ability to use telemedicine technology in adult patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA), and to determine associations with the socioeconomic characteristics of the patients, including age, sex, race, and education. We also sought to understand the patients’ perceived benefits, risks, and preferences when dealing with telemedicine. Methods. We performed a cross-sectional survey involving patients awaiting primary THA and TKA by one of six surgeons at a single academic institution. Patients were included and called for a telephone-administered survey if their surgery was scheduled to be between 23 March and 2 June 2020, and were aged > 18 years. Results. The response rate was 52% (189 of 363 patients). A total of 170 patients (90.4%) reported using the
Telehealth has the potential to change the way we approach patient care. From virtual consenting to reducing carbon emissions, costs, and waiting times, it is a powerful tool in our clinical armamentarium. There is mounting evidence that remote diagnostic evaluation and decision-making have reached an acceptable level of accuracy and can safely be adopted in orthopaedic surgery. Furthermore, patients’ and surgeons’ satisfaction with virtual appointments are comparable to in-person consultations. Challenges to the widespread use of telehealth should, however, be acknowledged and include the cost of installation, training, maintenance, and accessibility. It is also vital that clinicians are conscious of the medicolegal and ethical considerations surrounding the medium and adhere strictly to the relevant data protection legislation and storage framework. It remains to be seen how organizations harness the full spectrum of the technology to facilitate effective patient care. Cite this article:
We aim to explore the potential technologies for monitoring and assessment of patients undergoing arthroplasty by examining selected literature focusing on the technology currently available and reflecting on possible future development and application. The reviewed literature indicates a large variety of different hardware and software, widely available and used in a limited manner, to assess patients’ performance. There are extensive opportunities to enhance and integrate the systems which are already in existence to develop patient-specific pathways for rehabilitation. Cite this article:
This scoping review aims to identify patient-related factors associated with a poorer outcome following total ankle arthroplasty (TAA). A scoping review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A computer-based literature search was performed in PubMed, Embase, Cochrane trials, and Web of Science. Two reviewers independently performed title/abstract and full-text screening according to predetermined selection criteria. English-language original research studies reporting patient-related factors associated with a poorer outcome following TAA were included. Outcomes were defined as patient-reported outcome measures (PROMs), perioperative complications, and failure.Aims
Methods
This study aimed to compare the performance of survival prediction models for bone metastases of the extremities (BM-E) with pathological fractures in an Asian cohort, and investigate patient characteristics associated with survival. This retrospective cohort study included 469 patients, who underwent surgery for BM-E between January 2009 and March 2022 at a tertiary hospital in South Korea. Postoperative survival was calculated using the PATHFx3.0, SPRING13, OPTIModel, SORG, and IOR models. Model performance was assessed with area under the curve (AUC), calibration curve, Brier score, and decision curve analysis. Cox regression analyses were performed to evaluate the factors contributing to survival.Aims

This systematic review aimed to summarize the full range of complications reported following ankle arthroscopy and the frequency at which they occur. A computer-based search was performed in PubMed, Embase, Emcare, and ISI Web of Science. Two-stage title/abstract and full-text screening was performed independently by two reviewers. English-language original research studies reporting perioperative complications in a cohort of at least ten patients undergoing ankle arthroscopy were included. Complications were pooled across included studies in order to derive an overall complication rate. Quality assessment was performed using the Oxford Centre for Evidence-Based Medicine levels of evidence classification.Aims

Literature surrounding artificial intelligence (AI)-related applications for hip and knee arthroplasty has proliferated. However, meaningful advances that fundamentally transform the practice and delivery of joint arthroplasty are yet to be realized, despite the broad range of applications as we continue to search for meaningful and appropriate use of AI. AI literature in hip and knee arthroplasty between 2018 and 2021 regarding image-based analyses, value-based care, remote patient monitoring, and augmented reality was reviewed. Concerns surrounding meaningful use and appropriate methodological approaches of AI in joint arthroplasty research are summarized. Of the 233 AI-related orthopaedics articles published, 178 (76%) constituted original research, while the rest consisted of editorials or reviews. A total of 52% of original AI-related research concerns hip and knee arthroplasty (n = 92), and a narrative review is described. Three studies were externally validated. Pitfalls surrounding present-day research include conflating vernacular (“AI/machine learning”), repackaging limited registry data, prematurely releasing internally validated prediction models, appraising model architecture instead of inputted data, withholding code, and evaluating studies using antiquated regression-based guidelines. While AI has been applied to a variety of hip and knee arthroplasty applications with limited clinical impact, the future remains promising if the question is meaningful, the methodology is rigorous and transparent, the data are rich, and the model is externally validated. Simple checkpoints for meaningful AI adoption include ensuring applications focus on: administrative support over clinical evaluation and management; necessity of the advanced model; and the novelty of the question being answered.

The COVID-19 pandemic led to a swift adoption of telehealth in orthopaedic surgery. This study aimed to analyze the satisfaction of patients and surgeons with the rapid expansion of telehealth at this time within the division of adult reconstructive surgery at a major urban academic tertiary hospital. A total of 334 patients underging arthroplasty of the hip or knee who completed a telemedicine visit between 30 March and 30 April 2020 were sent a 14-question survey, scored on a five-point Likert scale. Eight adult reconstructive surgeons who used telemedicine during this time were sent a separate 14-question survey at the end of the study period. Factors influencing patient satisfaction were determined using univariate and multivariate ordinal logistic regression modelling.Aims

Meeting preoperative expectations is known to be of major influence on postoperative satisfaction after total knee arthroplasty (TKA). Improved management of expectation, resulting in more realistic expectations can potentially lead to higher postoperative satisfaction. The objective of this study was to assess the effect of an additional preoperative education module, addressing realistic expectations for long-term functional recovery, on postoperative satisfaction and expectation fulfilment. In total, 204 primary TKA patients with osteoarthritis were enrolled in this randomized controlled trial (RCT). Patients were allocated to either usual preoperative education (control group) or usual education plus an additional module on realistic expectations (intervention group). Primary outcome was being very satisfied (numerical rating scale for satisfaction ≥ 8) with the treatment result at 12 months' follow-up. Other outcomes were change in preoperative expectations and postoperative expectation fulfilment.Aims
Methods
Spinal deformity surgery carries the risk of neurological injury. Neurophysiological monitoring allows early identification of intraoperative cord injury which enables early intervention resulting in a better prognosis. Although multimodal monitoring is the ideal, resource constraints make surgeon-directed intraoperative transcranial motor evoked potential (TcMEP) monitoring a useful compromise. Our experience using surgeon-directed TcMEP is presented in terms of viability, safety, and efficacy. We carried out a retrospective review of a single surgeon’s prospectively maintained database of cases in which TcMEP monitoring had been used between 2010 and 2017. The upper limbs were used as the control. A true alert was recorded when there was a 50% or more loss of amplitude from the lower limbs with maintained upper limb signals. Patients with true alerts were identified and their case history analyzed.Aims

To establish whether there was a consensus among the members of the Hip Society (HS) on the role of direct anterior approach (DAA) contemporary primary total hip arthroplasty (THA). An online survey was sent to all 112 active and senior members of the HS, to which 71 members responded. The survey was constructed to determine whether they believed that evidence-based medicine proves, in modern clinical practice, that the DAA has significant benefits compared to risks when contrasted with other approaches. In addition, they were asked if they currently used the DAA.Aims

Malignancy and surgery are risk factors for venous thromboembolism (VTE). We undertook a systematic review of the literature concerning the prophylactic management of VTE in orthopaedic oncology patients. MEDLINE (PubMed), EMBASE (Ovid), Cochrane, and CINAHL databases were searched focusing on VTE, deep vein thrombosis (DVT), pulmonary embolism (PE), bleeding, or wound complication rates.Aims

This study aimed to develop a virtual clinic for the purpose of reducing face-to-face orthopaedic consultations. Anonymized experts (hip and knee arthroplasty patients, surgeons, physiotherapists, radiologists, and arthroplasty practitioners) gave feedback via a Delphi Consensus Technique. This consisted of an iterative sequence of online surveys, during which virtual documents, made up of a patient-reported questionnaire, standardized radiology report, and decision-guiding algorithm, were modified until consensus was achieved. We tested the patient-reported questionnaire on seven patients in orthopaedic clinics using a ‘think-aloud’ process to capture difficulties with its completion.Aims

The best method of treating unstable pelvic fractures that involve
the obturator ring is still a matter for debate. This study compared
three methods of treatment: nonoperative, isolated posterior fixation
and combined anteroposterior stabilization. The study used data from the German Pelvic Trauma Registry and
compared patients undergoing conservative management (n = 2394),
surgical treatment (n = 1345) and transpubic surgery, including
posterior stabilization (n = 730) with isolated posterior osteosynthesis
(n = 405) in non-complex Type B and C fractures that only involved the
obturator ring anteriorly. Calculated odds ratios were adjusted
for potential confounders. Outcome criteria were intraoperative
and general short-term complications, the incidence of nerve injuries,
and mortality.Aims

Since redesign of the Oxford phase III mobile-bearing unicompartmental
knee arthroplasty (UKA) femoral component to a twin-peg design,
there has not been a direct comparison to total knee arthroplasty
(TKA). Thus, we explored differences between the two cohorts. A total of 168 patients (201 knees) underwent medial UKA with
the Oxford Partial Knee Twin-Peg. These patients were compared with
a randomly selected group of 177 patients (189 knees) with primary
Vanguard TKA. Patient demographics, Knee Society (KS) scores and
range of movement (ROM) were compared between the two cohorts. Additionally,
revision, re-operation and manipulation under anaesthesia rates
were analysed.Aims

The use of journal clubs and, more recently,
case-based discussions in order to stimulate debate among orthopaedic
surgeons lies at the heart of orthopaedic training and education. A
virtual learning environment can be used as a platform to host virtual
journal clubs and case-based discussions. This has many advantages
in the current climate of constrained time and diminishing trainee
and consultant participation in such activities. The virtual environment
model opens up participation and improves access to journal clubs
and case-based discussions, provides reusable educational content,
establishes an electronic record of participation for individuals,
makes use of multimedia material (including clinical imaging and
photographs) for discussion, and finally, allows participants to
link case-based discussions with relevant papers in the journal
club. The Leicester experience highlights the many advantages and some
of the potential difficulties in setting up such a virtual system
and provides useful guidance for those considering such a system
in their own training programme. As a result of the virtual learning
environment, trainee participation has increased and there is a
trend for increased consultant input in the virtual journal club
and case-based discussions. It is likely that the use of virtual environments will expand
to encompass newer technological approaches to personal learning
and professional development.
Satisfaction with care is important to both patients
and to those who pay for it. The Net Promoter Score (NPS), widely
used in the service industries, has been introduced into the NHS
as the ‘friends and family test’; an overarching measure of patient
satisfaction. It assesses the likelihood of the patient recommending
the healthcare received to another, and is seen as a discriminator
of healthcare performance. We prospectively assessed 6186 individuals
undergoing primary lower limb joint replacement at a single university
hospital to determine the Net Promoter Score for joint replacements
and to evaluate which factors contributed to the response. Achieving pain relief (odds ratio (OR) 2.13, confidence interval
(CI) 1.83 to 2.49), the meeting of pre-operative expectation (OR
2.57, CI 2.24 to 2.97), and the hospital experience (OR 2.33, CI
2.03 to 2.68) are the domains that explain whether a patient would
recommend joint replacement services. These three factors, combined
with the type of surgery undertaken (OR 2.31, CI 1.68 to 3.17),
drove a predictive model that was able to explain 95% of the variation
in the patient’s recommendation response. Though intuitively similar,
this ‘recommendation’ metric was found to be materially different
to satisfaction responses. The difference between THR (NPS 71) and
TKR (NPS 49) suggests that no overarching score for a department
should be used without an adjustment for case mix. However, the
Net Promoter Score does measure a further important dimension to
our existing metrics: the patient experience of healthcare delivery. Cite this article:

The effective capture of outcome measures in
the healthcare setting can be traced back to Florence Nightingale’s
investigation of the in-patient mortality of soldiers wounded in
the Crimean war in the 1850s. Only relatively recently has the formalised collection of outcomes
data into Registries been recognised as valuable in itself. With the advent of surgeon league tables and a move towards value
based health care, individuals are being driven to collect, store
and interpret data. Following the success of the National Joint Registry, the British
Association of Spine Surgeons instituted the British Spine Registry.
Since its launch in 2012, over 650 users representing the whole
surgical team have registered and during this time, more than 27 000
patients have been entered onto the database. There has been significant publicity regarding the collection
of outcome measures after surgery, including patient-reported scores.
Over 12 000 forms have been directly entered by patients themselves,
with many more entered by the surgical teams. Questions abound: who should have access to the data produced
by the Registry and how should they use it? How should the results
be reported and in what forum? Cite this article:
The aim of this study was to determine whether
obesity affects pain, surgical and functional outcomes following lumbar
spinal fusion for low back pain (LBP). A systematic literature review and meta-analysis was made of
those studies that compared the outcome of lumbar spinal fusion
for LBP in obese and non-obese patients. A total of 17 studies were
included in the meta-analysis. There was no difference in the pain
and functional outcomes. Lumbar spinal fusion in the obese patient resulted
in a statistically significantly greater intra-operative blood loss
(weighted mean difference: 54.04 ml; 95% confidence interval (CI)
15.08 to 93.00; n = 112; p = 0.007) more complications (odds ratio:
1.91; 95% CI 1.68 to 2.18; n = 43858; p <
0.001) and longer duration
of surgery (25.75 mins; 95% CI 15.61 to 35.90; n = 258; p <
0.001). Obese
patients have greater intra-operative blood loss, more complications
and longer duration of surgery but pain and functional outcome are
similar to non-obese patients. Based on these results, obesity is
not a contraindication to lumbar spinal fusion. Cite this article:
We validated the North American Spine Society (NASS) outcome-assessment instrument for the lumbar spine in a computerised touch-screen format and assessed patients’ acceptance, taking into account previous computer experience, age and gender. Fifty consecutive patients with symptomatic and radiologically-proven degenerative disease of the lumbar spine completed both the hard copy (paper) and the computerised versions of the NASS questionnaire. Statistical analysis showed high agreement between the paper and the touch-screen computer format for both subscales (intraclass correlation coefficient 0.94, 95% confidence interval (0.90 to 0.97)) independent of computer experience, age and gender. In total, 55% of patients stated that the computer format was easier to use and 66% preferred it to the paper version (p <
0.0001 among subjects expressing a preference). Our data indicate that the touch-screen format is comparable to the paper form. It may improve follow-up in clinical practice and research by meeting patients’ preferences and minimising administrative work.
We report the effect of introducing a dedicated
Ponseti service on the five-year treatment outcomes of children
with idiopathic clubfoot. Between 2002 and 2004, 100 feet (66 children; 50 boys and 16
girls) were treated in a general paediatric orthopaedic clinic.
Of these, 96 feet (96%) responded to initial casting, 85 requiring
a tenotomy of the tendo-Achillis. Recurrent deformity occurred in
38 feet and was successfully treated in 22 by repeat casting and/or
tenotomy and/or transfer of the tendon of tibialis anterior, The
remaining 16 required an extensive surgical release. Between 2005 and 2006, 72 feet (53 children; 33 boys and 20 girls)
were treated in a dedicated multidisciplinary Ponseti clinic. All
responded to initial casting: 60 feet (83.3%) required a tenotomy
of the tendo-Achillis. Recurrent deformity developed in 14, 11 of
which were successfully treated by repeat casting and/or tenotomy
and/or transfer of the tendon of tibialis anterior. The other three
required an extensive surgical release. Statistical analysis showed that children treated in the dedicated
Ponseti clinic had a lower rate of recurrence (p = 0.068) and a
lower rate of surgical release (p = 0.01) than those treated in
the general clinic. This study shows that a dedicated Ponseti clinic, run by a well-trained
multidisciplinary team, can improve the outcome of idiopathic clubfoot
deformity. Cite this article:
Drug therapy forms an integral part of the management
of many orthopaedic conditions. However, many medicines can produce
serious adverse reactions if prescribed inappropriately, either
alone or in combination with other drugs. Often these hazards are
not appreciated. In response to this, the European Union recently
issued legislation regarding safety measures which member states
must adopt to minimise the risk of errors of medication. In March 2014 the Medicines and Healthcare products Regulatory
Agency and NHS England released a Patient Safety Alert initiative
focussed on errors of medication. There have been similar initiatives
in the United States under the auspices of The National Coordinating
Council for Medication Error and The Joint Commission on the Accreditation
of Healthcare Organizations. These initiatives have highlighted
the importance of informing and educating clinicians. Here, we discuss common drug interactions and contra-indications
in orthopaedic practice. This is germane to safe and effective clinical
care. Cite this article:
Previous studies of failure mechanisms leading
to revision total knee replacement (TKR) performed between 1986 and
2000 determined that many failed early, with a disproportionate
amount accounted for by infection and implant-associated factors
including wear, loosening and instability. Since then, efforts have
been made to improve implant performance and instruct surgeons in
best practice. Recently our centre participated in a multi-centre evaluation
of 844 revision TKRs from 2010 to 2011. The purpose was to report
a detailed analysis of failure mechanisms over time and to see if
failure modes have changed over the past 10 to 15 years. Aseptic
loosening was the predominant mechanism of failure (31.2%), followed
by instability (18.7%), infection (16.2%), polyethylene wear (10.0%),
arthrofibrosis (6.9%) and malalignment (6.6%). The mean time to
failure was 5.9 years (ten days to 31 years), 35.3% of all revisions
occurred at less than two years, and 60.2% in the first five years.
With improvements in implant and polyethylene manufacture, polyethylene
wear is no longer a leading cause of failure. Early mechanisms of
failure are primarily technical errors. In addition to improving
implant longevity, industry and surgeons must work together to decrease
these technical errors. All reports on failure of TKR contain patients
with unexplained pain who not infrequently have unmet expectations.
Surgeons must work to achieve realistic patient expectations pre-operatively,
and therefore, improve patient satisfaction post-operatively. Cite this article:

Intravenous tranexamic acid (TXA) has been shown
to be effective in reducing blood loss and the need for transfusion
after joint replacement. Recently, there has been interest in applying
it topically before the closure of surgical wounds. This has the
advantages of ease of application, maximum concentration at the
site of bleeding, minimising its systemic absorption and, consequently,
concerns about possible side-effects. We conducted a systematic review and meta-analysis which included
14 randomised controlled trials (11 in knee replacement, two in
hip replacement and one in both) which investigated the effect of
topical TXA on blood loss and rates of transfusion. Topical TXA
significantly reduced the rate of blood transfusion (total knee
replacement: risk ratio (RR) 4.51; 95% confidence interval (CI):
3.02 to 6.72; p <
0.001 (nine trials, I2 = 0%); total
hip replacement: RR 2.56; 95% CI: 1.32 to 4.97, p = 0.004 (one trial)).
The rate of thromboembolic events with topical TXA were similar
to those found with a placebo. Indirect comparison of placebo-controlled
trials of topical and intravenous TXA indicates that topical administration
is superior to the intravenous route. In conclusion, topical TXA is an effective and safe method of
reducing the need for blood transfusion after total knee and hip
replacement. Further research is required to find its optimum dose
for topical use. Cite this article:
Squeaking arising from a ceramic-on-ceramic (CoC)
total hip replacement (THR) may cause patient concern and in some

THR that reported squeaking, or revision for squeaking, were entered
into the analysis. The incidence of squeaking was 4.2% and the incidence

Surgical decision-making in lumbar spinal stenosis
involves assessment of clinical parameters and the severity of the
radiological stenosis. We suspected that surgeons based surgical
decisions more on dural sac cross-sectional area (DSCA) than on
the morphology of the dural sac. We carried out a survey among members
of three European spine societies. The axial T2-weighted MR images
from ten patients with varying degrees of DSCA and morphological
grades according to the recently described morphological classification
of lumbar spinal stenosis, with DSCA values disclosed in half the
assessed images, were used for evaluation. We provided a clinical
scenario to accompany the images, which were shown to 142 responding
physicians, mainly orthopaedic surgeons but also some neurosurgeons
and others directly involved in treating patients with spinal disorders.
As the primary outcome we used the number of respondents who would
proceed to surgery for a given DSCA or morphological grade. Substantial
agreement among the respondents was observed, with severe or extreme
stenosis as defined by the morphological grade leading to surgery.
This decision was not dependent on the number of years in practice, medical
density or specialty. Disclosing the DSCA did not alter operative
decision-making. In all, 40 respondents (29%) had prior knowledge
of the morphological grading system, but their responses showed
no difference from those who had not. This study suggests that the
participants were less influenced by DSCA than by the morphological
appearance of the dural sac. Classifying lumbar spinal stenosis according to morphology rather
than surface measurements appears to be consistent with current
clinical practice.
With the established success of the National
Joint Registry and the emergence of a range of new national initiatives for
the capture of electronic data in the National Health Service, orthopaedic
surgery in the United Kingdom has found itself thrust to the forefront
of an information revolution. In this review we consider the benefits
and threats that this revolution poses, and how orthopaedic surgeons
should marshal their resources to ensure that this is a force for
good.
Increasing numbers of posterior lumbar fusions
are being performed. The purpose of this study was to identify trends
in demographics, mortality and major complications in patients undergoing
primary posterior lumbar fusion. We accessed data collected for
the Nationwide Inpatient Sample for each year between 1998 and 2008
and analysed trends in the number of lumbar fusions, mean patient
age, comorbidity burden, length of hospital stay, discharge status,
major peri-operative complications and mortality. An estimated 1 288 496
primary posterior lumbar fusion operations were performed between
1998 and 2008 in the United States. The total number of procedures,
mean patient age and comorbidity burden increased over time. Hospital
length of stay decreased, although the in-hospital mortality (adjusted
and unadjusted for changes in length of hospital stay) remained
stable. However, a significant increase was observed in peri-operative
septic, pulmonary and cardiac complications. Although in-hospital mortality
rates did not change over time in the setting of increases in mean
patient age and comorbidity burden, some major peri-operative complications
increased. These trends highlight the need for appropriate peri-operative services
to optimise outcomes in an increasingly morbid and older population
of patients undergoing lumbar fusion.
Patient-reported outcome measures (PROMs) are
increasingly being used to assess functional outcome and patient satisfaction.
They provide a framework for comparisons between surgical units,
and individual surgeons for benchmarking and financial remuneration.
Better performance may bring the reward of more customers as patients and
commissioners seek out high performers for their elective procedures.
Using National Joint Registry (NJR) data linked to PROMs we identified
22 691 primary total knee replacements (TKRs) undertaken for osteoarthritis
in England and Wales between August 2008 and February 2011, and
identified the surgical factors that influenced the improvements
in the Oxford knee score (OKS) and EuroQol-5D (EQ-5D) assessment
using multiple regression analysis. After correction for patient
factors the only surgical factors that influenced PROMs were implant
brand and hospital type (both p <
0.001). However, the effects
of surgical factors upon the PROMs were modest compared with patient
factors. For both the OKS and the EQ-5D the most important factors
influencing the improvement in PROMs were the corresponding pre-operative
score and the patient’s general health status. Despite having only
a small effect on PROMs, this study has shown that both implant
brand and hospital type do influence reported subjective functional
scores following TKR. In the current climate of financial austerity,
proposed performance-based remuneration and wider patient choice,
it would seem unwise to ignore these effects and the influence of
a range of additional patient factors.
We review the history and literature of hip resurfacing arthroplasty. Resurfacing and the science behind it continues to evolve. Recent results, particularly from the national arthroplasty registers, have spread disquiet among both surgeons and patients. A hip resurfacing arthroplasty is not a total hip replacement, but should perhaps be seen as a means of delaying it. The time when hip resurfacing is offered to a patient may be different from that for a total hip replacement. The same logic can apply to the timing of revision surgery. Consequently, the comparison of resurfacing with total hip replacement may be a false one. Nevertheless, the need for innovative solutions for young arthroplasty patients is clear. Total hip replacement can be usefully delayed in many of these patients by the use of hip resurfacing arthroplasty.
