Aims

The evidence base within trauma and orthopaedics has traditionally favoured quantitative research methodologies. Qualitative research can provide unique insights which illuminate patient experiences and perceptions of care. Qualitative methods reveal the subjective narratives of patients that are not captured by quantitative data, providing a more comprehensive understanding of patient-centred care. The aim of this study is to quantify the level of qualitative research within the orthopaedic literature.

Aims. Open lower limb fracture is life-changing, resulting in substantial morbidity and resource demand, while inconsistent outcome-reporting hampers systematic review and meta-analysis. A core outcome set establishes consensus among key stakeholders for the recommendation of a minimum set of outcomes. This study aims to define a core outcome set for adult open lower limb fracture. Methods. Candidate outcomes were identified from a previously published systematic review and a secondary thematic analysis of 25 patient interviews exploring the lived experience of recovery from open lower limb fracture. Outcomes were categorized and sequentially refined using healthcare professional and patient structured discussion groups. Consensus methods included a multi-stakeholder two-round online Delphi survey and a consensus meeting attended by a purposive sample of stakeholders, facilitated discussion, and voting using a nominal group technique. Results. Thematic analysis and systematic review identified 121 unique outcomes, reduced to 68 outcomes following structured discussion groups. Outcomes were presented to 136 participants who completed a two-round online Delphi survey. The Delphi survey resulted in 11 outcomes identified as consensus ‘in’ only. All outcomes were discussed at a consensus meeting attended by 15 patients, 14 healthcare professionals, 11 researchers, and one patient-carer. Consensus was achieved for a four-core outcome set: ‘Walking, gait and mobility’, ‘Being able to return to life roles’, ‘Pain or discomfort’, and ‘Quality of life’. Conclusion. This study used robust consensus methods to establish a core outcome set that should be measured in all future research studies and audits of clinical practice without precluding the measurement of additional outcomes.

A huge commitment is required from patients and families who undergo a limb reconstruction procedure using the hexapod frame. This includes turning the struts on the frame, pin site care and intensive rehabilitation. Montpetit et al (2009) discovered that function, participation, engagement in regular activities of daily living is severely impacted during the hexapod lengthening period. Due to the long duration and burden for families, it is imperative that healthcare professionals understand the impact that the hexapod frame has on functional abilities and health related quality of life (HRQL). This project involved a retrospective review of prospectively collected data on function and HRQL during two periods of time: (1) when the hexapod frame is applied on the child's lower extremity and (2) when the lengthening phase is completed, and the hexapod frame is removed. Data from 38 children (mean age: 12 years SD 3.8) who completed lower extremity reconstruction using the hexapod frame and completed either or both the Pediatric Quality of Life Inventory 4.0 Generic Core Scale (PedsQL) and Pediatric Outcomes data Collection Instrument (PODCI) was included. Analysis included, standardized response means, the non-parametric Wilcoxon test and effect size calculation. A Wilcoxon signed rank test for those children who completed pre and post frame PODCI’;s revealed those scores were significantly greater once the hexapod frame was removed (Md=85.10, n=10) compared to during (Md=66.50, n=10) with a large effect size, r= 1.45. Similar, the PedsQL scores improved post frame removal (Md= 66.30, n=10) compared to during treatment (Md = 53.34, n=10), with a medium size effect, r= 0.62. All subtests improved once the frame was removed. This study provides essential insights into the burden of the hexapod frame for children and provides valuable information for all allied healthcare professionals targeted interventions for health domains. This study shows that children's function improves once the hexapod frame is removed. However, this study highlights the importance for all healthcare professional to address health domains for the duration of the hexapod procedure where the child scored lower e.g. sports and physical function, pain and comfort, happiness from the PODCI. The PedsQL identified lower mean scores in physical and emotional function

Abstract. Introduction. The knee is the most commonly injured joint in sporting accidents. They cause substantial disability, time off work and long-term problems. There remains a limited number of high-quality randomised controlled trials assessing first time, acute soft tissue knee injuries. Key areas requiring answers include prevention, diagnosis, treatment, rehabilitation and delivery of care. In association with the James Lind Alliance, this BASK, BOSTAA and BOA supported prioritising exercise was undertaken over a year. Methodology. The James Lind Alliance methodology was followed. An initial survey invited patients and healthcare professionals to submit their uncertainties regarding soft tissue knee injury prevention, diagnosis, treatment, rehabilitation and delivery of care. Over 1000 questions were submitted. Seventy-four questions were formulated to encompass common concerns. These were checked against best available evidence. Following the interim survey, 27 questions were taken forward to the final workshop in January 2023, where they were discussed, ranked and scored in multiple rounds of prioritisation by groups of healthcare professionals, patients and carers. Results. The Top 10 includes prevention, diagnosis, treatment and rehabilitation questions, reflecting the concerns of patients, carers and a wider multidisciplinary team. These will be presented and explained. Conclusion. This validated process has generated an important Top 10, which has been submitted to the National Institute for Health and Care Research. All 27 questions will be published, thus being available for researchers to investigate. The questions in the Top 10 will lead to future high quality research, thus improving patient outcomes

Purpose and background. Low back pain burdens individuals, society and services, including Emergency Departments (ED), straining services and prolonging wait times. Despite reported personal influences on deciding to attend ED, the role of third-party advice remains underexplored. Sparse guidance for clinicians and service-users highlights the need for effective back pain management strategies, to alleviate system pressure and optimise patient outcomes. This study explored how advice influences the decision to attend the ED for back pain. Methods and Results. From a subtle realist stance, the design was a secondary analysis of qualitative data, where 47 patients (26M:21F, aged 23–79 years) with back pain were purposively sampled from four EDs (2 Northern and 2 Southern) in England between August and December 2021. Eight patients had previously visited ED for this episode of back pain. As this was during the pandemic, semi-structured interviews were conducted online, audio-recorded, transcribed verbatim and analysed using a reflective thematic analysis. Three themes were identified as crucial in making the decision to attend ED: The Healthcare professional; Trusted others; and the Individual. Healthcare professionals often dictated decisions, leaving participants feeling powerless. Trusted others provided varying support levels, often acting as allies. Individuals grappled with anxieties around their condition and treatment expectations. Conclusion. This study highlights the need for clinicians to provide clarity and guidance to individuals and their Trusted others, seeking advice regarding escalation to visit the ED with back pain. There was evidence that worrying about pain was a significant motivator for attending ED, resulting in malalignment with current practice guidelines. No conflicts of interest.  . Sources of funding.

Introduction. The knee is the most commonly injured joint in sporting accidents, leading to substantial disability, time off work and morbidity (1). Treatment and assessment vary around the UK (2), whilst there remains a limited number of high-quality randomised controlled trials assessing first time, acute soft tissue knee injuries (3,4). As the clinical and financial burden rises (5), vital answers are required to improve prevention, diagnosis, treatment, rehabilitation, and delivery of care. In association with the James Lind Alliance, this BASK, BOSTAA and BOA supported prioritising exercise was undertaken over a year. Methods. The James Lind Alliance methodology was followed; a modified nominal group technique was used in the final workshop. An initial survey invited patients and healthcare professionals to submit their uncertainties regarding soft tissue knee injury prevention, diagnosis, treatment, rehabilitation, and delivery of care. Seventy-four questions were formulated to encompass common concerns. These were checked against best available evidence. Following the interim survey, 27 questions were taken forward to the final workshop in January 2023, where they were discussed, ranked, and scored in multiple rounds of prioritisation by groups of healthcare professionals, patients, and carers. Results. Over 1000 questions were submitted initially. Twenty-seven were taken forward to the final workshop following the surveys. Nearly half of the responses were from patients/carers. The Top 10 (Figure 1) includes prevention, diagnosis, treatment, and rehabilitation questions, reflecting the concerns of patients, carers, and a wider multidisciplinary team. Conclusion. This validated process has generated an important, wide- ranging Top 10 priorities for future soft tissue knee injury research. These have been submitted to the National Institute for Health and Care Research and are now available for researchers to investigate. The final 27 questions which were taken to the final workshop have also been published on the James Lind Alliance website. Research into these questions will lead to future high-quality research, thus improving patient care & outcomes. For any figures or tables, please contact authors directly

Aims. A core outcome set for adult, open lower limb fracture has been established consisting of ‘Walking, gait and mobility’, ‘Being able to return to life roles’, ‘Pain or discomfort’, and ‘Quality of life’. This study aims to identify which outcome measurement instruments (OMIs) should be recommended to measure each core outcome. Methods. A systematic review and quality assessment were conducted to identify existing instruments with evidence of good measurement properties in the open lower limb fracture population for each core outcome. Additionally, shortlisting criteria were developed to identify suitable instruments not validated in the target population. Candidate instruments were presented, discussed, and voted on at a consensus meeting of key stakeholders. Results. The Wales Lower Limb Trauma Recovery scale was identified, demonstrating validation evidence in the target population. In addition, ten candidate OMIs met the shortlisting criteria. Six patients, eight healthcare professionals, and 11 research methodologists attended the consensus meeting. Consensus was achieved for the EuroQol five-dimension five-level questionnaire (EQ-5D-5L) and the Lower Extremity Functional Scale (LEFS) to measure ‘Quality of life’ and ‘Walking, gait and mobility’ in future research trials, audit, and clinical assessment, respectively. No instrument met consensus criteria to measure ‘Being able to return to life roles’ and ‘Pain or discomfort’. However, the EQ-5D-5L was found to demonstrate good face validity and could also be used pragmatically to measure these two outcomes, accepting limitations in sensitivity. Conclusion. This study recommends the LEFS and EQ-5D-5L to measure the core outcome set for adult open lower limb fracture. Cite this article: Bone Joint Res 2023;12(6):352–361

Aims. To explore key stakeholder views around feasibility and acceptability of trials seeking to prevent post-traumatic osteoarthritis (PTOA) following knee injury, and provide guidance for next steps in PTOA trial design. Methods. Healthcare professionals, clinicians, and/or researchers (HCP/Rs) were surveyed, and the data were presented at a congress workshop. A second and related survey was then developed for people with joint damage caused by knee injury and/or osteoarthritis (PJDs), who were approached by a UK Charity newsletter or Oxford involvement registry. Anonymized data were collected and analyzed in Qualtrics. Results. Survey responses (n = 19 HCP/Rs, 39 PJDs) supported studies testing pharmacological agents preventing PTOA. All HCP/Rs and 30/31 (97%) PJDs supported the development of new treatments that improved or delayed knee symptoms and damage to knee structure. PJDs thought that improving structural knee damage was more important than knee symptoms. Both groups found studies more acceptable as expected future benefit and risk of PTOA increased. All drug delivery routes were acceptable. Workshop participants (around n = 60) reflected survey views. Discussions suggested that stratifying using molecular testing for likely drug response appeared to be more acceptable than using characteristics such as sex, age, and BMI. Conclusion. Our findings supported PTOA drug intervention studies, including situations where there is low risk of disease, no expected benefit of treatment, and frequent treatment administration. PJDs appeared less risk-averse than HCP/Rs. This work reinforces the benefits of consensus and involvement work in the co-creation of PTOA drug trial design. Involvement of key stakeholders, such as PJDs with different risks of OA and regulatory representatives, are critical for trial design success. Cite this article: Bone Joint Res 2024;13(9):513–524

Aims. The aim of this study was to describe the current pathways of care for patients with a fracture of the hip in five low- and middle-income countries (LMIC) in South Asia (Nepal and Sri Lanka) and Southeast Asia (Malaysia, Thailand, and the Philippines). Methods. The World Health Organization Service Availability and Readiness Assessment tool was used to collect data on the care of hip fractures in Malaysia, Thailand, the Philippines, Sri Lanka, and Nepal. Respondents were asked to provide details about the current pathway of care for patients with hip fracture, including pre-hospital transport, time to admission, time to surgery, and time to weightbearing, along with healthcare professionals involved at different stages of care, information on discharge, and patient follow-up. Results. Responses were received from 98 representative hospitals across the five countries. Most hospitals were publicly funded. There was consistency in clinical pathways of care within country, but considerable variation between countries. Patients mostly travel to hospital via ambulance (both publicly- and privately-funded) or private transport, with only half arriving at hospital within 12 hours of their injury. Access to surgery was variable and time to surgery ranged between one day and more than five days. The majority of hospitals mobilized patients on the first or second day after surgery, but there was notable variation in postoperative weightbearing protocols. Senior medical input was variable and specialist orthogeriatric expertise was unavailable in most hospitals. Conclusion. This study provides the first step in mapping care pathways for patients with hip fracture in LMIC in South Asia. The previous lack of data in these countries hampers efforts to identify quality standards (key performance indicators) that are relevant to each different healthcare system.

Introduction. There are currently no quality of life Patient Reported Outcome Measures (PROMs) that have been validated for patients with conditions requiring lower limb reconstructive surgery. The extent to which current generic and lower limb specific PROMs address relevant dimensions for these patients is unclear. Materials and Methods. We will present an overview of the PROLLIT (Patient-Reported Outcome Measure for Lower Limb Reconstruction) mixed-methods study. PROLLIT aims to establish the adequacy of current PROMS for this population, whether a new measure is required, and to develop a new measure if appropriate. Results. The PROLLIT study consists of three phases:. Phase 1 is currently underway and involves the development of a conceptual model to map the key quality of life constructs relevant to people undergoing reconstructive surgery, to specify the intended population and uses of a PROM in this field. The conceptual model is being developed in a 3 step process: (i) Existing evidence is being collated in a systematic review of published qualitative research (Qualitative Evidence Synthesis); (ii) a multi-site qualitative study of patients, orthopaedic surgeons, specialist nurses and physiotherapists; (iii) an interdisciplinary panel of patients, surgeons, healthcare professionals and methodologists to finalise the conceptual framework based on the findings of the Qualitative Evidence Synthesis (i) and qualitative study (ii). Phase 2 involves mapping the conceptual framework onto existing PROMs measures that are used with this population to determine whether the constructs identified as important by patients and healthcare professionals are reflected in existing PROMS. Phase 3 involves developing a new outcome measure, if deemed necessary/appropriate during Phase 2. Conclusions. Current PROMS may not adequately address the issues relevant to patients recovering from lower limb reconstructive surgery. Phase 1 and 2 will provide robust evidence as to whether this is the case in order to seek funding for research to develop a new measure (Phase 3)

The development of spinal deformity in children with underlying neurodisability can affect their ability to function and impact on their quality of life, as well as compromise provision of nursing care. Patients with neuromuscular spinal deformity are among the most challenging due to the number and complexity of medical comorbidities that increase the risk for severe intraoperative or postoperative complications. A multidisciplinary approach is mandatory at every stage to ensure that all nonoperative measures have been applied, and that the treatment goals have been clearly defined and agreed with the family. This will involve input from multiple specialities, including allied healthcare professionals, such as physiotherapists and wheelchair services. Surgery should be considered when there is significant impact on the patients’ quality of life, which is usually due to poor sitting balance, back or costo-pelvic pain, respiratory complications, or problems with self-care and feeding. Meticulous preoperative assessment is required, along with careful consideration of the nature of the deformity and the problems that it is causing. Surgery can achieve good curve correction and results in high levels of satisfaction from the patients and their caregivers. Modern modular posterior instrumentation systems allow an effective deformity correction. However, the risks of surgery remain high, and involvement of the family at all stages of decision-making is required in order to balance the risks and anticipated gains of the procedure, and to select those patients who can mostly benefit from spinal correction

Background. Chronic pain is a significant burden and represents a major issue for world healthcare systems. Interventions include medication, surgery, pain management programmes, and social support through peer support groups. These groups are often informal, providing informational, emotional, and social support to members. The aim of this project is to co-produce guidance on how to establish a peer support programme for people living with chronic, non-cancer pain that is informed by evidence, theory, and stakeholder experience. Methods. This project is using Steps 1–4 of the Intervention Mapping (IM) approach to inform the research. Online workshops consisting of people living with chronic pain, third sector representatives, healthcare professionals, and researchers are being used to co-produce the guidance. Results. To date, 2 of the 4 planned workshops have been conducted. These have identified the needs of people living with chronic pain, goals for the peer support programme, and expectations of how a peer support programme should be executed. Topics for inclusion in the programme and their content have been identified, with further workshops to refine this planned. The final stage of this project will identify methods of delivery, specific resources that should be developed, and the training to be provided to peer support volunteers. Conclusion. The project has identified the diverse needs of people living with chronic pain and how these may be addressed by a peer support programme. It has identified flexible options that can be recommended to those who want to set up a programme and a variety content that may be included. Conflicts of Interest. None. Sources of Funding.

The UK falls behind other European countries in the early detection of Developmental Dysplasia of the hip (DDH) and there remains controversy surrounding screening strategies for early detection. Clinical detection of DDH is challenging and recognised to be dependent on examiner experience. No studies exist assessing the number of personnel currently involved in such assessments. Our objective was to study the current screening procedure by studying a cohort of new-born babies in one teaching hospital and assess the number of health professionals involved in neonatal hip assessment and the number of examinations undertaken during one period by each individual. This was a retrospective observational study assessing all babies born consecutively over a 14-week period in 2020. Record of each initial baby check was obtained from Maternity or Neonatal Badger. Follow-up data on ultrasound or orthopaedic outpatient referrals were obtained from clinical records. 1037 babies were examined by 65 individual examiners representing 9 different healthcare professional groups. The range of examinations conducted per examiner was 1- 97 with a mean of 15.9 examinations per person. 49% individuals examined 5 or less babies across the 14 weeks, with 18% only performing 1 examination. Of the 5 babies (0.48%) treated for DDH, one was picked up on neonatal assessment. In a system where so many examiners are involved in neonatal hip assessment the experience is limited for most examiners. It is unsurprising that high current rates of late presentation of DDH are observed locally, which are in accordance with published national experience

Introduction. The aim of this study was to assess patients and healthcare professionals (HCPs) opinions on the validity of using a biopsychosocial model rather than a biomedical model in alleviating patient symptoms/pain. Method. We constructed a questionnaire to assess beliefs on the effectiveness of using a biopsychosocial or biomedical model to develop a treatment plan to optimise patient symptoms/pain. We distributed the questionnaire to new and follow-up patients and healthcare professional in the orthopaedic department. Results. 246 questionnaires were completed - 183 patients and 63 HCPs. The patient group consisted of 77 males and 106 females, the HCP group of 27 males and 36 females. 77(42%) of patients and 9(14%) of HCPs agree the biomedical model is best suited to treat symptoms. 81(44%) of patients and 62(98%) of HCPs agree the biopsychosocial model is best suited to treat symptoms. 70(38%) of patients and 61 (97%) of HCPs agree stress can increase pain. 87(48%) of patients and 62(98%) of HCPs agree distress can increase pain. 83(45%) of patients and 56(89%) of HCPs agree stress can increase disability. 81(44%) of patients and 56(89%) of HCPs agree distress can increase disability. 39(21%) of patients and 43(68%) of HCPs agree if all investigations show no abnormality in explaining symptoms, the main contributor is stress, distress or psychological/socioeconomic factor. Conclusion. HCPs recognise the biopsychosocial model as a useful tool in managing patients pain/symptoms which not recognised by patients. HCPs believe that stress, distress, psychological/socioeconomic factors have a significant impact on a patients pain and disability when compared to patients. No conflicts of interest. No funding obtained

Introduction. The heterogeneity of outcomes used in the field of lower limb lengthening surgery (LLLS) affects our ability to synthesize evidence. This hampers robust systematic reviews and treatment recommendations for clinical practice. Ultimately this reduces the impact of research for both patients and healthcare professionals. This scoping review aimed to describe the outcomes and outcome measurement instruments (OMIs) used within the field of LLLS. Method. A systematic literature search of WOS, Scopus, Embase, MEDLINE, and the Cochrane Library identified all studies reporting outcomes in children and adults after LLLS. All outcomes and OMIs were extracted verbatim. An iterative process was used to group outcome terms under standardized outcome headings categorized using the COMET Taxonomy of Outcomes. Result. Data saturation was achieved in 2020. A total of 142 studies were included between 2024-2020, reporting 2964 verbatim outcomes with 663 standardized outcome terms collapsed into 119 outcome headings (subdomains). A total of 29 patient-reported and 26 clinician-reported outcome instruments were identified. The most commonly reported outcome was “Lengthening amount”, reported in over 72% of the included studies, while “health-related quality of life” was measured in 16% and all life impact outcomes were reported in 19% of the included studies. Conclusion. A large number of peer-reviewed publications are available, demonstrating that significant resources are being devoted to research on LLLS. However, reported outcomes for people with LLLS are heterogeneous, subject to reporting bias, and vary widely in the definitions and measurement tools used to collect them. Outcomes likely to be important to patients, such as quality of life and measures of physical function, have been neglected. This scoping review identifies a need to standardize outcomes and outcome measures reported on patients recovering from lower limb lengthening surgery; this can be addressed by creating a core set of outcomes

Introduction. Hip prosthetic joint infection (PJI) is a debilitating complication following joint replacement surgery, with significant impact on patients and healthcare systems. The INFection ORthopaedic Management: Evidence into Practice (INFORM: EP) study, builds upon the 6-year INFORM programme by developing evidence-based guidelines for the identification and management of hip PJI. Methods. A panel of 21 expert stakeholders collaborated to develop best practice guidelines based on evidence from the previous INFORM research programme. An expert consensus process was used to refine guidelines using RAND/UCLA criteria. The guidelines were then implemented over a 12-month period through a Learning Collaborative of 24 healthcare professionals from 12 orthopaedic centres in England. Qualitative interviews were conducted with 17 members of the collaborative and findings used to inform the development of an implementation support toolkit. Patient and public involvement contextualised the implementation of the guidelines. The study is registered with the ISCRTN (34710385). Result. The INFORM guidelines, structured around the stages of PJI management, were largely supported by surgeons, although barriers included limited awareness among non-surgical team members, lack of job planning for multidisciplinary teams, and challenges in ensuring timely referrals from primary care. Psychological support for patients was identified as a critical gap. Advanced Nurse Practitioners and multidisciplinary team (MDT) coordinators were seen as potential bridges to address these knowledge gaps. The guidelines were also viewed as a useful tool for service development. Conclusions. This study presents the first evidence-based guidelines for hip PJI management, offering a comprehensive approach to prevention, treatment, and postoperative care. Effective implementation is crucial, involving wider dissemination amongst primary and community care, as well as non-specialist treatment centres. Further resources are needed to ensure job planning for MDTs and psychological support for patients. Overall, this study lays the foundation for improved PJI management, benefiting patients and healthcare systems

Introduction. LIMB-Q Kids is a new patient-reported outcome measure (PROM) for children with Lower limb differences (LLDs). The objective is to conduct an international field test study. Materials & Methods. A mixed method multiphase approach was used to develop LIMB-Q Kids. In phase one, a systematic review was conducted to identify concepts from existing PROMs used in research with children with LLDs. A preliminary conceptual framework derived from the systematic review informed an international qualitative study. The data from qualitative interviews were used to form the LIMB-Q Kids, which was further refined through multiple rounds of cognitive debriefing interviews with children. Input was obtained from parents and healthcare professionals from Australia, Canada, Ethiopia, India, UK, and the USA. LIMB-Q Kids was translated and culturally adapted into multiple languages. Results. The final field-test version consists of 11 scales (159 items) that measure appearance, physical function, symptoms (hip, knee, ankle, foot, and leg), leg-related distress, and school, social and psychological function. This version was rigorously translated into Danish and German. Translations that are in progress include Arabic, Finnish, Hindi, Swahili, Portuguese, Spanish, and Luganda. An international field-test study is underway in nine countries (15 sites with a target recruitment of 150 participants per country). At the time of abstract submission, 190 patients from seven sites have completed LIMB-Q Kids. The UK collaborative has worked on language adaption for the UK and is currently validating the score across five paediatric limb reconstruction units. Conclusions. No internationally applicable PROM exists for children with LLDs. We present the current progress in developing and validating such a score. Data from the international field-test study will be used to reduce items and perform psychometric testing of LIMB-Q Kids. The rigorous translation and cultural adaption process will provide versions of LIMB-Q Kids in different languages. Once completed, the LIMB-Q Kids will provide a common metric for outcome assessment for children with lower limb differences internationally

The increased demand for total hip arthroplasty (THA) is having a significant impact on healthcare resources, resulting in increased interest in outpatient care pathways to reduce resource consumption. This study compared costs between patients who underwent outpatient THA using a Direct Anterior (DA) approach compared to a Direct Lateral (DL) approach to understand the effect of surgical approach on resource use. We conducted a prospective randomized controlled trial for DA patients undergoing primary THA. We compared patients in the outpatient arm of the trial to a prospective cohort of outpatient DL approach THAs. We recorded all costs including: equipment, length of stay in hospital, and laboratory or other medical tests. Following discharge, participants also completed a self-reported cost diary recording resource utilization such as emergency department visits or subsequent hospitalizations, tests and procedures, consultations or follow-up, healthcare professional services, rehabilitation, use of pain medications, informal care, productivity losses and out of pocket expenditures. We report costs from both Canadian public health care payer (HCP) and a societal perspective. The HCP perspective includes any direct health costs covered by the publicly funded system. In addition to the health care system costs, the societal perspective also includes additional costs to the patient (e.g. physiotherapy, medication, or assistive devices), as well as any indirect costs such as time off paid employment for patients or caregivers. We included 127 patients in the DA group (66.6 years old) and 51 patients in the DL group (59.4 years old) (p<0.01). There were no statistically significant differences in costs between groups from both the healthcare payer (DA= 7910.19, DL= 7847.17, p=0.80) and societal perspectives (DA= 14657.21, DL= 14581.21, p=0.96). In patients undergoing a successful outpatient hip replacement, surgical approach does not have an effect on cost from in hospital or societal perspectives

We recently performed a clinical trial comparing motor sparing blocks (MSB) to periarticular infiltration (PAI) following total knee arthroplasty (TKA). We found that MSBs provided longer analgesia (8.8 hours) than PAI with retention of quadriceps strength, and with similar function, satisfaction, and length of hospital stay. However, its potential increased cost could serve as a barrier to its adoption. Therefore, our aim was to compare the costs of MSBs to PAI following TKA. We conducted a retrospective review of data from our previous RCT. There were 82 patients included in the RCT (n=41 MSB group, n=41 PAI group). We compared the mean total costs associated with each group until hospital discharge including intervention costs, healthcare professional service fees, intraoperative medications, length of stay, and postoperative opioid use. Seventy patients were included (n=35 MSB group, n=35 PAI group). The mean total costs for the MSB group was significantly higher ($1959.46 ± 755.4) compared to the PAI group ($1616.25 ± 488.33), with a mean difference of $343.21 (95% CI = $73.28 to $664.11, p = 0.03). The total perioperative intervention costs for performing the MSB was also significantly higher however postoperative inpatient costs including length of stay and total opioid use did not differ significatnly. Motor sparing blocks had significantly higher mean total and perioperative costs compared to PAI with no significant difference in postoperative inpatient costs. However, its quadricep sparing nature and previously demonstrated prolonged postoperative analgesia can be used to facilitate an outpatient TKA pathway thereby offsetting its increased costs
