Objectives. To assess the clinical and cost-effectiveness of a virtual fracture clinic (VFC) model, and supplement the literature regarding this service as recommended by The National Institute for Health and Care Excellence (NICE) and the British Orthopaedic Association (BOA). Methods. This was a retrospective study including all patients (17 116) referred to fracture clinics in a London District General Hospital from May 2013 to April 2016, using hospital-level data. We used interrupted time series analysis with segmented regression, and direct before-and-after comparison, to study the impact of VFCs introduced in December 2014 on six clinical parameters and on local Clinical Commissioning Group (CCG) spend. Student’s t-tests were used for direct comparison, whilst segmented regression was employed for projection analysis. Results. There were statistically significant reductions in numbers of new patients seen face-to-face (140.4, . sd. 39.6 versus 461.6, . sd. 61.63, p < 0.0001), days to first orthopaedic review (5.2, . sd. 0.66 versus 10.9, . sd. 1.5, p < 0.0001), discharges (33.5, . sd. 3.66 versus 129.2, . sd. 7.36, p < 0.0001) and non-attendees (14.82, . sd. 1.48 versus 60.47, . sd. 2.68, p < 0.0001), in addition to a statistically significant increase in number of patients seen within 72-hours (46.4% 3873 of 8345 versus 5.1% 447 of 8771, p < 0.0001). There was a non-significant increase in consultation time of 1 minute 9 seconds (14 minutes 53 seconds . sd. 106 seconds versus 13 minutes 44 seconds . sd. 128 seconds, p = 0.0878). VFC saved the local CCG £67 385.67 in the first year and is set to save £129 885.67 annually thereafter. Conclusions. We have shown VFCs are clinically and cost-effective, with improvement across several clinical performance parameters and substantial financial savings for CCGs. To our knowledge this is the largest study addressing clinical practice implications of VFCs in England, using robust methodology to adjust for pre-existing trends. Further studies are required to appreciate whether our results are reproducible with local variations in the VFC model and payment tariffs. Cite this article: A. McKirdy, A. M. Imbuldeniya.

Articular cartilage injury has a high prevalence in elite and recreational athletes. Articular cartilage repair remains a challenge due to cost effectiveness and clinical effectiveness issues. There are now several effective technologies and it is possible to return to competitive sports following many of the procedures available. The durability of repair tissue is variable and there remains extensive growth in the Scientific world. Evolving cartilage restoration technologies focus on increasing cartilage quality and quantity, while optimising surgery and rehabilitation. In UK ACI has undergone extensive cost effectiveness analysis and the in-depth review has shown that ACI is cost effective compared to microfracture. ACI is indicated for lesions >2cm sq but NICE has considered that it is not indicated for problems after microfracture. This presentation details the various options available to surgeons and examines the cost effectiveness

Is Non-Weight-Bearing Necessary? (INWN) is a pragmatic multicentre randomised controlled trial comparing immediate protected weight-bearing (IWB) with non-weight-bearing cast immobilisation (NWB) following ankle fracture fixation (ORIF). This trial compares; functional outcomes, complication rates and performs an economic analysis to estimate cost-utility. IWB within 24hrs was compared to NWB, following ORIF of all types of unstable ankle fractures. Skeletally immature patients and tibial plafond fractures were excluded. Functional outcomes were assessed by the Olerud-Molander Ankle Score (OMAS) and RAND-36 Item Short Form Survey (SF-36) taken at regular follow-up intervals up to one year. A cost-utility analysis via decision tree modelling was performed to derive an incremental cost effectiveness ratio (ICER). A standard gamble health state valuation model utilising SF-36 scores was used to calculate Quality Adjusted Life Years (QALYs) for each arm. We recruited 160 patients (80 per arm), aged 15 to 94 years (M = 45.5), 54% female. Complication rates were similar in both groups. IWB demonstrated a consistently higher OMAS score, with significant values at 6 weeks (MD=10.4, p=0.005) and 3 months (MD 12.0, p=0.003). Standard gamble utility values demonstrated consistently higher values (a score of 1 equals perfect health) with IWB, significant at 3 months (Ẋ = 0.75 [IWB] / 0.69 [NWB], p=0.018). Cost-utility analysis demonstrated NWB is €798.02 more expensive and results in 0.04 fewer QALYs over 1 year. This results in an ICER of −€21,682.42/QALY. This negative ICER indicates cost savings of €21,682.42 for every QALY (25 patients = 1 QALY gain) gained implementing an IWB regime. IWB demonstrates a superior functional outcome, greater cost savings and similar complication rates, compared to NWB following ankle fracture fixation

Telemedicine is the delivery of healthcare from a remote location using integrated computer/communication technology. This systematic review aims to explore evidence for telemedicine in orthopaedics to determine its advantages, validity, effectiveness and utilisation particularly during our current pandemic where patient contact is limited. Databases of PubMed, Scopus and CINHAL were systematically searched and articles were included if they involved any form of telephone or video consultation in an orthopaedic population. Findings were synthesised into four themes: patient/clinician satisfaction, accuracy and validity of examination, safety and patient outcomes and cost effectiveness. Quality assessment was undertaken using Cochrane and Joanna Briggs Institute appraisal tools. Twenty studies were included consisting of nine RCTs across numerous orthopaedic subspecialties including fracture care, elective orthopaedics and oncology. Studies revealed high patient satisfaction with telemedicine for convenience, less waiting and travelling time. Telemedicine was cost effective particularly if patients had to travel long distances, required hospital transport or time off work. No clinically significant differences were found in patient examination nor measurement of patient reported outcome measures. Telemedicine was reported to be a safe method of consultation. However, studies were of variable methodological quality with selection bias. In conclusion, evidence suggests that telemedicine in orthopaedics can be safe, cost effective, valid in clinical assessment with high patient/clinician satisfaction. Further work with high quality RCTs is required to elucidate long term outcomes. This systematic review presents up-to-date evidence on the use of telemedicine and provides data for organisations considering its use in the current COVID-19 pandemic and beyond

Objectives. “Virtual fracture clinics” have been reported as a safe and effective alternative to the traditional fracture clinic. Robust protocols are used to identify cases that do not require further review, with the remainder triaged to the most appropriate subspecialist at the optimum time for review. The objective of this study was to perform a “top-down” analysis of the cost effectiveness of this virtual fracture clinic pathway. Methods. National Health Service financial returns relating to our institution were examined for the time period 2009 to 2014 which spanned the service redesign. Results. The total staffing costs rose by 4% over the time period (from £1 744 933 to £1 811 301) compared with a national increase of 16%. The total outpatient department rate of attendance fell by 15% compared with a national fall of 5%. Had our local costs increased in line with the national average, an excess expenditure of £212 705 would have been required for staffing costs. Conclusions. The virtual fracture clinic system was associated with less overall use of staff resources in comparison to national cost data. Adoption of this system nationally may have the potential to achieve significant cost savings. Cite this article: P. J. Jenkins.

Financial and human cost effectiveness is an increasing evident outcome measure of surgical innovation. Considering the human element, the aim is to restore the individual to their “normal” state by sparing anatomy without compromising implant performance. Gait lab studies have shown differences between different implants at top walking speed, but none to our knowledge have analysed differing total hip replacement patients through the entire range of gait speed and incline to show differences. The purpose of this gait study was to 1) determine if a new short stem femoral implant would return patients back to normal 2) compare its performance to established hip resurfacing and long stem total hip replacement (THR) implants. 110 subjects were tested on an instrumented treadmill (Kistler Gaitway, Amherst, NY), 4 groups (short-stem THR, long-stem THR, hip resurfacing and healthy controls) of 28, 29, 27, and 26 respectively. The new short femoral stem patients (Furlong Evolution, JRI) were taken from the ongoing Evolution Hip trial that have been tested on the treadmill with minimum 12months postop. The long stem total hip replacements and hip resurfacing groups were identified from out 800 patient gait database. They were only chosen if they were 12 months postop and had no other joint disease or medical comorbidities which would affect gait performance. All subjects were tested through their entire range of gait speeds and incline after having a 5 minute habituation period. Speed intervals were at 0.5kms increments until maximum walking speed achieved and inclines at 4kms for 5, 10, 15%. At all incremental intervals of speed, the vertical component of the ground reaction forces, center of pressure and temporal measurements were collected for both limbs with a sampling frequency of 100Hz. Body weight scaling was applied to correct for mass differences and a symmetry index to compare the implanted hip to the contralateral normal hip. All variables for each subject group were compared to each other using an analysis of variance (ANOVA) with Tukey post hoc test with significance set at α=0.05. The four experimental groups were reasonably matched for demographics and the implant groups for PROMs. Hip resurfacing had a clear top walking speed advantage, but when assessing the symmetry index on all speeds and incline, all groups were not significantly different. Push-off and step length was statistically less favourable for the short/long THR group (p=0.005–0.05) depending on speed/incline. The primary aim of this study was determine if implant design affected gait symmetry and performance. Interestingly, irrespective of implant design, symmetry with regards to weight acceptance, impulse, push-off and step length was returned to normal when comparing to healthy controls. However individual implant performance on the flat and incline, showed inferior (p<0.05) push-off force and step length in the short stem and long stem THR groups when compared to controls. Age and gender may have played a part for the short stem group. It appears that the early gait outcomes for the short stem device are promising. Assessment at the 3 year mark should be conclusive

In 2012 collagenase Clostridium histolyticum (Xiapex) was approved by the SMC for restricted use for the treatment of Dupuytren's contracture. Xiapex was approved on a case by case basis for patients with a palpable pretendinous cord, giving rise to MCPJ contracture of greater than 30 degrees. As of September 2012 we began to offer Xiapex injections to patients in Ayrshire who enquired about the injection, and met the SMC criteria. To date injections have been performed on 3 patients, in a total of 7 digits. Patients were assessed prior to injection and manipulation, with the degree of contracture recorded and DASH scores noted. Each patient then underwent a standard injection of 0.58 mg of Xiapex. 48 hours post injection each patient underwent manipulation under local anaesthetic, with contractures remeasured, pain scored using a visual analogue scale and complications noted. Each patient was then reviewed at 4 weeks post injection where the residual degree of contracture was recorded and a further DASH score completed. Mean contracture at the MCPJ prior to injection was 57° (range 34–80), and mean DASH score of 20.8 (range 16.7–24.2). Following manipulation mean residual contracture at the MCPJ measured 21° (range 18–28). The average pain score following was manipulation was rated at 1.1. Mild bruising and swelling were reported in all cases following injection, and manipulation resulted in 2 minor skin tears. At the 4 week review prolonged improvement of contracture was achieved with a mean residual contracture of 14° (range −2–40); with a significant improvement in DASH scores – mean 0.6 (range 0–1.8). Despite small numbers, we have found Xiapex injections to be a successful and well tolerated treatment for moderate Dupuytren's disease. Further follow up is required to assess the longevity of the correction and ensure the cost effectiveness of Xiapex

Summary Statement. Using current analysis/methodology, new implant technology is unlikely to demonstrate a large enough change in patient function to impact on the cost-effectiveness of the procedure. Purpose. Cost effectiveness is an increasingly important metric in today's healthcare environment, and decisions surrounding which arthroplasty prosthesis to implant are not exempt from such health economic concerns. Quality adjusted life years (QALYs) are the typical assessment tool for this type of evaluation. Using this methodology, joint arthroplasty has been shown to be cost effective, however studies directly comparing the QALY achieved by differing prostheses are lacking. Methods. Data was gathered in a single centre prospective double-blind randomised controlled trial comparing the outcome a modern implant, the Triathlon total knee replacement, with its traditionally designed predecessor the Kinemax, using the Short Form 6 dimensional (SF-6D) score and quality adjusted life year (QALY) methodology. The study cohort consisted of 64 patients that were randomised to a Triathlon and 60 randomised to a Kinemax. Results. There was a significant improvement in the SF-6D score for both groups at one year compared with pre-operative scores (p<0.0001). The calculated overall life expectancy for the study cohort was 15.1 years, which resulted in an overall QALY gain of 2.144 (95% CI 1.752–2.507). The modern implant group demonstrated only a small improvement in the SF-6D score compared to the traditional design at one year (0.141 versus 0.143, p=0.94). This difference in health gain resulted in the modern implant costing £298 less per QALY at one year, however this saving diminished to less than £30 per year over the lifetime of the cohort. Discussion. This study demonstrates that despite comparing 2nd and 4th generation design, modern implant technology does not influence the cost-effectiveness of TKA using the SF-6D and QALY methodology. As most implants demonstrate similar longevity, differences in patient function will likely carry the greatest influence on QALY. This type of analysis however assesses health status, and is not sensitive to joint specific function. Dramatic differences in patient outcome would be required to influence QALY score. Evolutionary design changes in implant technology are thus unlikely to influence QALY analysis following joint replacement, which has important implication for implant procurement

This protocol describes a pragmatic multicentre randomised controlled trial (RCT) to assess the clinical and cost effectiveness of arthroscopic and open surgery in the management of rotator cuff tears. This trial began in 2007 and was modified in 2010, with the removal of a non-operative arm due to high rates of early crossover to surgery.
