Background. Individual illness perceptions have been shown to be important influences on both clinical and work outcomes for those with back pain, yet the influence of ‘significant others’ (spouse/partner/close family member) illness perceptions is rarely explored, particularly in relation to work participation. Method. Semi-structured interviews based on the Illness Perceptions Questionnaire were conducted with two purposive samples of chronic back pain patients (working and work disabled), along with their significant others (n=28). Data were analysed using template analysis. Results. The significant others of patients who were work disabled tended to reinforce the patients' limitations and negative consequences of the back pain condition on every aspect of their lives. They believed that patients needed to be pain-free in order to resume work, and equated treatment success with complete removal of pain. Overall, they perceived patients to be blameless victims. In contrast, the significant others of patients who had managed to remain at work despite persistent back pain focused instead on what the patient could still do, were more accepting of treatment as providing pain management rather than a cure, and tended to describe patients as being stoical and heroic. Conclusions. This exploratory in-depth research reveals novel and interesting insights about the illness beliefs of significant others in relation to persistent back pain, and highlights the wider social circumstances that may act as barriers/facilitators to work participation.

The process of gaining informed consent can be a complex and much debated pursuit, especially within a paediatric setting. The role of the trainee surgeon and its explanation to children and their families prior to an operation has not been explored from the resident surgeons' point of view. Ten face-to-face interviews were conducted with orthopaedic surgery trainees at a tertiary level paediatric hospital in Toronto, Canada. These were transcribed and subsequently thematically coded by 3 reviewers. Three main themes were identified from the interviews. 1) Surgical trainees feel their level of participation and autonomy gradually increases dependent on their observed skills and level of training. 2) Trainees feel the consent process is adequate but acknowledge it is often purposely vague with regards to their intra-operative involvement as this is often unpredictable and it avoids patient/family anxiety. 3) Trainees believe families are aware of their participation however most likely underestimate their role during operations. Trainees in surgical specialties believe their level of autonomy is variable dependent on a number of factors and that this impacts on the ability to be more specific when gaining informed consent. This must be balanced with a family's right to an appropriate understanding of their child's operation and who is performing it. It may be that further patient education regarding trainees and their role in operations would help develop a more thorough and patient centred informed consent process

Background

Surgical resection of middle facet tarsal coalition is a well documented treatment option in symptomatic individuals that do not respond to conservative treatment. The ability to return to full recreational activity post resection may have implications on foot biomechanics and possibly degenerative changes in the subtalar and adjacent joints.

Primary malignant bone and soft tissue tumours often occur in the lower extremities of active individuals including children, teenagers and young adults. Survivors routinely face long-term physical disability. Participation in sports is particularly important for active young people but the impact of sarcoma treatment is not widely recognised and clinicians may be unable to provide objective advice about returning to sports. We aimed to identify and summarise the current evidence for involvement in sports following treatment of lower limb primary malignant bone and soft tissue tumours. A comprehensive search strategy was used to identify relevant studies combining the main concepts of interest: (1) Bone/Soft Tissue Tumour, (2) Lower Limb, (3) Surgical Interventions and (4) Sports. Studies were selected according to eligibility criteria with the consensus of three authors. Customised data extraction and quality assessment tools were used. 22 studies were selected, published between 1985 – 2020, and comprising 1005 patients. Fifteen studies with data on return to sports including 705 participants of which 412 (58.4%) returned to some form of sport at a mean follow-up period of 7.6 years. Four studies directly compared limb sparing and amputation; none of these were able to identify a difference in sports participation or ability. Return to sports is important for patients treated for musculoskeletal tumours, however, there is insufficient published research to provide good information and support for patients. Future prospective studies are needed to collect better pre and post-treatment data at multiple time intervals and validated clinical and patient sports participation outcomes such as type of sports participation, level and frequency and a validated sports specific outcome score, such as UCLA assessment. In particular, more comparison between limb sparing and amputation would be welcome

Introduction. Symptomatic hip dysplasia is often treated with periacetabular osteotomy (PAO). Studies investigating the effect of PAO have primarily focused on radiographic measurements, pain-related outcomes, and hip survival whereas evidence related to sport participation is limited. Methods. All patients in our institutional database were deemed eligible for this cohort study if they underwent PAO and had answered at least one question related to sport participation. Patients were asked if they were playing sport preoperatively, 6 months after PAO as well as 2, 5, 10, 15 and 20 years after. In addition, patients were asked if they were able to play their preferred sport, what type and at what level they were playing sport, and if surgery had improved their sport performance. Results. Among 2398 patients surveyed, 1926 (80%) were included and 56% were playing sport 6 months after PAO. This number was 61% two years after PAO, and remained around that for the following years, before dropping 15 years after PAO. Between 56% and 71% of patients felt that their sporting performance improved following PAO at the different time points. Between 39% (6 months after PAO) and 63% (15 years after PAO) were able to participate in their preferred sport. Conclusion. The majority of patients undergoing PAO due to hip dysplasia will return to, and maintain, sport after PAO. More than half of patients undergoing PAO believe that the surgery improved their sports performance, and long after the surgery more than half of patients undergoing PAO are able to play their preferred sport

Abstract. Background. Femoroacetabular impingement (FAI) has been extensively investigated and is strongly associated with athletic participation. The aim of this systematic review is to assess: the prevalence of cam-type FAI across various sports, whether kinematic variation between sports influences hip morphology, and whether performance level, duration and frequency of participation or other factors influence hip morphology in a sporting population. Methods. A systematic search of Embase, PubMed and the Cochrane Library was undertaken following PRISMA guidelines. The study was registered on the PROSPERO database (CRD4202018001). Prospective and retrospective case series, case reports and review articles published after 1999 were screened and those which met the inclusion criteria decided a priori were included for analysis. Results. The literature search identified 58 relevant articles involving 5,683 participants. Forty-nine articles described a higher prevalence of FAI across various ‘hip-heavy’ sports, including soccer, basketball, baseball, ice hockey, skiing, golf and ballet. In studies including non-athlete controls, a greater prevalence of FAI was reported in 66.7% of studies (n=8/12). The highest alpha angle was identified at the 1 o'clock position (n=9/9) in football, skiing, golf, ice hockey and basketball. Maximal alpha angle was found to be located in a more lateral position in goalkeepers versus positional players in ice hockey (1 o'clock vs 1.45 o'clock). A positive correlation was also identified between the alpha angle and both age and activity level (n=5/8 and n=2/3, respectively) and also between prevalence of FAI and both age and activity level (n=2/2 and n=4/5), respectively. Conclusions. Hip-heavy sports show an increased prevalence of FAI, with specific sporting activities influencing hip morphology. Both a longer duration and increased level of training also resulted in an increased prevalence of FAI

Abstract. There are numerous advantages of discharging patients early after any surgery. Day case arthroplasty in hip and knee is already brought into practice at many centres. We present our journey towards discharging elective shoulder arthroplasty patient on same after their surgery. An initial retrospective study of patients who underwent elective shoulder replacement between 2017 and 2020 were studied. It was identified that a selected group of patients could be discharged on the same of their surgery. The criteria to select a patient for this service was laid down that include ASA 1 or 2, good family support on discharge, personal wishes of patients and early identification of potential patients in the clinic and planning for day case shoulder arthroplasty56 consecutive patients underwent elective arthroplasty of shoulder. Among them 22 patients were discharges on the next day of surgery. The potential patients those could discharged on same were identified to be 11 out of 22 were under ASA 2 and had good family support at home on discharge. Average length of stay after surgery was 2.17 days. We have prospectively discharged 2 patients following the new criteria. This study demonstrates how outpatient elective shoulder could be implemented at other centres. Patient participation and selection with proper planning is key for success here.

Access to health care, including physiotherapy, is increasingly occurring through virtual formats. At-home adherence to physical therapy programs is often poor and few tools exist to objectively measure low back physiotherapy exercise participation without the direct supervision of a medical professional. The aim of this study was to develop and evaluate the potential for performing automatic, unsupervised video-based monitoring of at-home low back physiotherapy exercises using a single mobile phone camera. 24 healthy adult subjects performed seven exercises based on the McKenzie low back physiotherapy program while being filmed with two smartphone cameras. Joint locations were automatically extracted using an open-source pose estimation framework. Engineered features were extracted from the joint location time series and used to train a support vector machine classifier (SVC). A convolutional neural network (CNN) was trained directly on the joint location time series data to classify exercises based on a recording from a single camera. The models were evaluated using a 5-fold cross validation approach, stratified by subject, with the class-balanced accuracy used as the performance metric. Optimal performance was achieved when using a total of 12 pose estimation landmarks from the upper and lower body, with the SVC model achieving a classification accuracy of 96±4% and the CNN model an accuracy of 97±2%. This study demonstrates the feasibility of using a smartphone camera and a supervised machine learning model to effectively assess at-home low back physiotherapy adherence. This approach could provide a low-cost, scalable method for tracking adherence to physical therapy exercise programs in a variety of settings

Virtual physiotherapy has been provided to hundreds of patients at the Holland Centre during the COVID pandemic. As we plan for virtual care to be one part of our care delivery we want to evaluate it and ensure the care delivery is safe and effective. The objectives of this project was two-fold: 1) to examine the outcome of virtual physiotherapy and/ or a hybrid of virtual and in-person care in patients who received post-operative treatment following total knee replacement at the Holland Centre, 2) to explore the challenges of virtual care participation in the joint replacement population. Patients who received either virtual care or a combination of in-person and virtual care (hybrid model) based on the patients’ needs were included. Patient-related outcomes were the Patient Specific Functional Scale (PSFS) and pain scale. Flexion and extension range of motion were measured before and after treatment. A modified Primary Care Patient Experience Virtual Care Survey was used to examine barriers for virtual care. Sixty patients, mean age 68(8), ranging between 45-83 years, 34(57%) females, who received either virtual care or a combination of in-person and virtual care based on the patients’ needs were included. Patients showed improvement in the PSFS and pain scores (p<0.0001). Flexion (p<0.0001) and extension (p=0.02) improved at a statistically significant level. A separate sample (N=54) (age range 50-85 years) completed the patient experience survey. A well-designed post-operative virtual physiotherapy program, initially implemented to maintain continuity of care during the pandemic, continues to be an important part of our model of care as we normalize our activities. Clear understanding of barriers to virtual care and mitigation strategies will help us create virtual care standards, meet our patient needs, optimize our care delivery and potentially increase the use of virtual rehab in the future

Abstract. Background. Recruitment of patients to participate in Randomised control trials (RCTs) is a challenging task, especially for trauma trials in which the identification and recruitment are time-limited. Multiple strategies have been tried to improve the participation of doctors and recruitment of patients. Aim. To study the effect of a trainee advocate (trainee Principal investigator-tPI) on influencing junior doctors to take part in trials and its effect on recruitment for a multicenter prospective hip fracture RCT. Methods. A retrospective study comparing the number of junior doctors participating in trials and patients recruited before and after the introduction of informal tPI role at UHW Cardiff. Results. The target recruitment set by the central trial unit was 9/month. Excluding the research team, there were 6 trainees actively recruiting in the before period (Feb’19-July’19) in comparison with 12 in the after period (Sept’19-Feb’20). TPI had a direct influence on 9 of the 11 trainees to get involved in the trials by guidance and nudging. There were 105 eligible patients of which 62 were recruited (59% of eligible pts, 115% of target) in the before period in comparison with 102 recruited (76% of eligible pts, 189% of target) out of the 135 eligible patients in the after period. The proportion of recruitment done by the research team to that of trainees was 79%:21% in the before period in comparison with 30%:70% in the after period further improving to 15%:85% in the last 3 months. Conclusion. TPI can work alongside the PI and research team to be a valuable link person coordinating and engaging local trainees to take part in trials. This may be particularly beneficial in hospitals where there is no dedicated research team. TPI role could be formalized for many trials and can be used as a leadership & management potential building experience for trainees. Declaration of Interest.

Total hip replacement (THR) is a common elective surgical procedure and can be effective for reducing chronic pain. However, waiting times for THR can be considerable, and patients often experience significant pain during this time. A pain self-management intervention may provide patients with the skills to enable them to manage their pain and its impact more effectively before surgery. However, studies of arthritis self-management programmes have faced challenges because of low recruitment rates, poor intervention uptake, and high attrition rates. This study aimed to evaluate the feasibility of a randomised controlled trial (RCT) to assess the effectiveness and cost-effectiveness of a group-based pain self-management course for patients undergoing THR. Specific objectives were to assess trial design, ascertain recruitment and retention rates, identify barriers to participation, refine data collection methods, and evaluate uptake and patient satisfaction with the course. Patients listed for THR in an elective orthopaedic centre Bristol, UK were sent a postal invitation about the study. Participants were randomised to attend a pain self-management course plus standard care or standard care only using a computer-generated randomisation system. The pain self-management course was delivered by Arthritis Care and consisted of two half-day group sessions prior to surgery and one full-day group session 2–4 months after surgery. A structured course evaluation questionnaire was completed by participants. Outcomes assessment was by postal questionnaire prior to surgery and 1-month, 3-months and 6-months after surgery. Self-report resource use data were collected using a diary prior to surgery and inclusion of resource use questions in the 3-month and 6-month post-operative questionnaires. Brief telephone interviews were conducted with non-participants to explore barriers to participation. Postal invitations were sent to 385 eligible patients and 88 patients consented to participate (23% recruitment rate). Participants had a mean age of 66 years and 65% were female. Brief interviews with 57 non-participants revealed the most common reasons for non-participation were perceptions about the intervention and difficulties in getting to the hospital for the course. Of the 43 patients randomised to the intervention group, 28 attended the pre-operative pain self-management sessions and 11 attended the post-operative sessions. Participant satisfaction with the course was high, and patients enjoyed the group format. Retention of participants was acceptable, with 83% completing follow-up. Questionnaire return rates were high (76–93%), with the exception of the pre-operative resource use diary (35%). Completion rates for the resource use questions varied by category and allowed for an economic perspective from the health and social care payer to be taken. Undertaking feasibility work for a RCT is labour-intensive; however this study highlights the importance of conducting such work. Postal recruitment resulted in a low recruitment rate and brief interviews with non-participants provided valuable information on barriers to participation. Embedding collection of resource use data within questionnaires resulted in higher completion rates than using resource use diaries. While patients who attended the course gave positive feedback, attendance was low. Findings from this feasibility study enable us to design successful definitive group-based RCTs in the future

Background. Inpatient physiotherapy is routinely provided after total knee replacement (TKR) surgery to enhance recovery prior to discharge. However, the provision of outpatient physiotherapy is variable in the UK, and the longer-term benefits of outpatient physiotherapy are unclear. This study aimed to evaluate the feasibility of conducting a randomised controlled trial (RCT) to assess the effectiveness and cost-effectiveness of group-based outpatient physiotherapy after TKR. Methods. Patients listed for primary TKR were recruited prior to surgery. Patients who decided not to participate were asked about their reasons for non-participation. Patients were randomised to attend a newly developed post-operative physiotherapy class plus usual care or usual care alone. Patients allocated to the intervention group were invited to attend a weekly one-hour physiotherapy class, starting at 6 weeks after surgery and running over 6 consecutive weeks. The group classes were run by two physiotherapists within an outpatient gym, and involved task-orientated and individualised exercises. Classes ran on a rolling system, allowing new patients to join each week. Participants completed an evaluation questionnaire after the final class. Outcomes assessment was by questionnaire prior to surgery and 2 weeks, 3 months and 6 months after surgery. Outcomes related to function, pain, balance, self-efficacy, participation, quality of life and resource use. Results. 46/124 patients consented to participate (37% recruitment rate). Frequent reasons for non-participation were related to travelling distance, transportation, and time commitments. 17/23 patients randomised to the intervention group attended the exercise classes. Most (15) patients were very satisfied with the range of exercises on offer. The task-orientated and individual exercises were given average usefulness ratings of 9.6/10 and 9.5/10, respectively. Retention of participants was acceptable; 2 patients were withdrawn from the intervention group and 2 patients from the usual care group. Questionnaire return rates were high in the intervention group (91% at 6 months post-operative) but lower in the usual care group (65% at 6 months post-operative). Conclusion. This study highlights the importance of conducting feasibility work for a RCT. Collecting data on reasons for non-participation provided valuable information on barriers to participation in a trial with this population. The intervention was well attended, and feedback was positive. Questionnaire completion was lower in the usual care group, highlighting the need for additional strategies to improve data collection. Findings from this feasibility study have informed the design of a multi-centre RCT to evaluate the clinical and cost-effectiveness of a group-based outpatient physiotherapy intervention following TKR

The key points of this talk are: (a) STEM skills are increasingly required by employers across a broad range of sectors. These skills help to foster systemic and critical thinking in a number of areas and are not confined to four subjects alone. Due to the increasing digitalisation of society and the world of work the demand for STEM skills will only intensify. (b) There is a need to increase the number of STEM-qualified people in Ireland and across Europe with employers highlighting a specific shortage of people with these skills. This is particularly apparent as concerns engineers, computer scientists and data analysts. To achieve this, it is necessary to raise awareness of the STEM-related careers that are available and to promote participation in STEM courses and studies, notably among women. (c) Parents, teachers, employers and education and training providers, both through their individual and joint actions, have a key role to play in fostering STEM skills acquisition

Onset and progression of osteoarthritis (OA) is affected by a plethora of factors, including joint injury, obesity, aging, and heredity. This multi-factorial etiology obstructs our understanding of driving molecular mechanisms, which likely comprise an interplay between systemic and local factors. Next to biomechanical factors and cytokines, the course of OA appears to be altered by microenvironmental oxidative stress: cumulative evidence now suggests a prominent participation of cell signalling mediated by nuclear factor (erythroid-derived 2)-like 2 (Nrf2), a master regulator of cellular protective processes, in this process. Nrf2 activation through phosphorylation of mitogen-activated protein kinases (MAPKs) regulates Nrf2 target genes, like hemeoxygenase-1 (HO-1), superoxide dismutase 2 (SOD2), or NAD(P)H Quinone Dehydrogenase 1 (NQO1) in OA chondrocytes. Maintaining high levels of HO-1 appears to be beneficial against OA development. Experimental manipulation of putative antioxidant response element (ARE) binding sites alters the in vitro expression of key transcription factors of chondrocyte markers in promoter-reporter assays. Potentially, Nrf2 is involved in autophagy, intermediary metabolism and unfolded protein response. RNAi-mediated depletion of Nrf2 further significantly abrogated anti-inflammatory and chondroprotective effects and epigenetics link transcriptional pathways of ‘N-factors’, Nrf2 and NFATs, to micro-RNA signalling. Current findings thus reveal novel mechanisms regulating extracellular matrix synthesis by chondrocytes. A further understanding of these pathways and their regulation will lead to important novel targets to slow OA progression

Tourniquets have been used for many years during total knee arthroplasty (TKA). With a growing demand for TKA in recent years, tourniquet use has been surrounded by ongoing controversy due to many conflicting advantages and disadvantages of tourniquet use. Quantifying the case for or against tourniquet use in TKA, in terms of patient focused outcomes, is a priority. This meta-analysis analysed, the never before assessed, impact of tourniquet use during TKA on post-operative pain. We completed a systematic review and meta-analysis using PRISMA reporting guidelines to assess the impact of tourniquet use on patients post-TKA. Post-operative pain was the primary outcome. Secondary outcomes were post-operative range of motion (ROM) and length of stay (LOS). The initial search yielded 230 studies, of which 14 met the inclusion criteria. A post-operative increase in pain and reduction in ROM when using a tourniquet appeared significantly more likely when compared to no tourniquet use during TKA, yet with no overall difference in post-operative LOS. Subgroup meta-analysis demonstrated a trend that favoured the half-course tourniquet for reduced post-operative pain in patients when compared to full tourniquet use during TKA. This systematic review and meta-analysis concluded that the after-effects of tourniquet use in TKA patients and its impact on post-operative pain and ROM are indeed significant. We recommend further randomized controlled trials (RCTs) focusing on TKA patient outcomes of post-operative pain and ROM.

The significance of physical activity (PA) assessment is widely acknowledged as it can aid in the understanding of pathologies. PA of knee osteoarthritis (KOA) patients has been assessed with varying methods, as it is a disease that is known to impair physical function and activity during daily life. Differences between methods have been described for general outcomes (sport participation or sedentary time), yet failed to describe common activities such as stair locomotion or sit-to-stand (STS) transfers. This study therefore aimed to determine the comparability of various methods to assess daily-life activities in KOA patients. Sixty-one clinically diagnosed KOA patients wore a tri-axial accelerometer (AX3, Axivity, UK) for one week during waking hours. Furthermore, they performed three physical function tests: a 40-m fast-paced walk test (WT), a timed up-and-go test (TUGT) and a 15 stair-climb test (SCT). Patients were also asked to fill out the Knee Osteoarthritis Outcome Score (KOOS), a KOA-specific questionnaire. Patients were slightly overweight (average BMI: 27.3±4.8 kg/m2), 60 (±10) years old and predominantly female (53%). The amount of daily level walking bouts was only weakly correlated with the WT performance, representing patients” walking capacity, (ρ=−0.33, p=0.01). Similarly, level-walking bouts during daily life correlated weakly with self-perceived walking capacity addressed by the KOOS (ρ=−0.36, p=0.01). For stair locomotion, a slightly different trend was seen. A moderate correlation was found (ρ=0.65, p<0.001), between the amount of ascending bouts and the objective functional test performance (SCT). However, the subjective assessment of stair ascending limitations (via the KOOS) correlated only weakly with both the functional test performance and the measured level of activity (ρ=−0.30 and −0.35, resp.). Comparable results were found for descending motions. STS transfers during daily life correlated moderately at best with the time to complete the TUGT (ρ=−0.43, p<0.01) and only weakly with the self-perceived effort of STS transfers (ρ=−0.26, p=0.04). Only weak correlations existed between subjective measures and objective parameters (for both functional tests and daily living activities), indicating that they assess different domains (e.g. self-perceived function vs. actual physical function). Furthermore, when comparing the two objective measures, correlation coefficients increased compared to the subjective methods, yet did not reach strong agreement. These findings suggest that addressing common activities of daily life either subjectively or objectively will result in different patient-related outcomes of a study. Assessment methods should therefore be chosen with caution and compared carefully with other studies

Background. To aid recovery, rehabilitation is an important adjunct to surgery. Acknowledging the MRC framework for complex interventions we assessed the evidence-base for components of comprehensive rehabilitation in total hip (THR) and total knee replacement (TKR) pathways. Methods. We conducted systematic reviews and meta-analyses of randomised controlled trials (RCT) of pre-surgical exercise and education, occupational therapy and post-operative physiotherapy. In feasibility RCTs we explored acceptability of pain self-management and occupational therapy before THR, and physiotherapy after TKR. We searched trial registers for ongoing RCTs. Results. Pre-surgical interventions. Systematic review identified 38 interventions targeting physical function before THR and TKR. Interventions showed functional benefit compared with controls, standardised mean difference (SMD) 0.32 (95% CI 0.20, 0.44; p<0.00001). In 27 studies targeting in-hospital recovery, intervention patients had lower anxiety, SMD 0.38 (95% CI 0.13, 0.63; p=0.003), and earlier mobilisation by 4 hours (95% CI 0.04, 0.30; p=0.009). In 20 studies, interventions targeting long-term recovery showed no benefit for function or pain. We randomised 88 patients into a feasibility RCT of group-based pain self-management. Attendees were highly satisfied but participation was low. Pre-operatively, many patients may perceive that only surgery can treat their symptoms. Occupational therapy. Systematic review identified 7 small RCTs in THR. Function improved in patients receiving occupational therapy, SMD 0.40 (95%CI 0.09, 0.70; p=0.01) but this was not sustained post-surgery. In our feasibility study with 44 patients randomised to pre-operative provision of aids and appliances or usual care, the intervention was delivered successfully and acceptable to participants. We identified no ongoing studies. Post-discharge physiotherapy. Systematic review identified 7 small studies suggesting that physiotherapy after TKR gives functional benefit at 3–4 months, SMD 0.37 (95%CI 0.12, 0.62; p=0.004) but not at later follow up. As noted in a recent review in THR, quality of evidence was limited. Our feasibility study evaluated six weeks of group-based activity-orientated rehabilitation in 46 TKR patients. The programme was well-received and attendance good. A fully-powered RCT is underway. We identified two ongoing studies targeting patients at risk of, or with, poor recovery. Conclusion. The evidence-base for comprehensive rehabilitation in THR and TKR is growing. Pre-surgical interventions may be effective but, in isolation, not acceptable to many patients. Ongoing definitive trials in TKR physiotherapy will guide future care. Well-designed trials of physiotherapy after THR and occupational therapy are needed. Ultimately, rehabilitation interventions throughout THR and TKR pathways may provide optimal care but this will need appropriate evaluation

Background. Proximal femoral fracture is a common, major health problem resulting in loss of functional independence and a high cost burden on society. Rehabilitation can potentially maximise functional recovery, but evidence of effectiveness is lacking. An enhanced rehabilitation intervention designed to improve self-efficacy and increase the amount and quality of practice of physical exercise and activities of daily living has been developed consisting of patient held workbooks and extra therapy sessions in the community. This study aims to define characteristics of the cohort of individuals this intervention is targeted to, assess acceptability of the intervention and feasibility of recruiting participants for a larger scale trial. Methods. An anonymous cohort study of all proximal femoral fracture patients admitted to three acute hospitals will provide details on residence pre-admission, type of fracture, type of surgery, adverse events and subsequent readmissions. A separate randomised feasibility study recruiting participants from this cohort will assess acceptability and feasibility of the study in terms of eligibility, recruitment, reasons for decline, retention and outcome measure completion. The success rate of identifying patients for the feasibility study and whether the recruited participants are representative of the cohort population will be evaluated by comparison of the feasibility participant screening and background data with that of the cohort. Results. 541 patients were screened for the feasibility study between June 2014 and February 2015 (ongoing). 298 were ineligible, 243 were eligible and 53 (22%) have been recruited to date. Lack of capacity is the leading cause of ineligibility and burden of taking part is perceived as a significant block to participation. Completion rate of outcome measures is high at baseline and follow up. Conclusions. Recruitment from the acute setting is challenging. However, study processes, outcome measurement and intervention is well tolerated by participants. Level of Evidence. I - Well conducted Randomised Trial (Pilot)

Background. Patient reported outcomes measures are a fundamental part of the NHS. Since 2009, they have been used to measure quality from the patient's perspective. PROMS2.0 is a semi-automated web based system, which allows collection and analysis of outcome data. This study looks at the factors, which can influence PROMS. These include looking at general trends which affect reported outcomes such as surgeon, age and gender. We also look to assess the reasons for non-uptake in the study. Methods. Data was collected from October 2012 to March 2015. Scores used to asses outcome measures included EQ-5D VAS, EQ-5D Health Index, and MOxFQ, collected pre-operatively and post-operatively. Results. 97/350 (27.8%) (69F+28M) patients consented and provided pre-op and post op scores. Average age was 57.2 years (Range-19–89). 69 Rt Vs 36 Lt. Surgeon A-51, B-31, C-8 procedures. MOxFQ- all three domains improved on average- Pain- 51.2 to 28.2. Walking/standing- 53.5 to 30.4 and Social interaction- 46.1 to 27.3. EQ5D scores also improved. VAS- 76.0 to 79.7, Index- 0.70 to 0.74. Patients over 70 showed the greatest improvement in MOxFQ, over 70s and under 50s did the same in EQ5D. Male patients reported better outcomes overall in both scores. All statistically significant. No significant patterns found between different surgeons. Left sided procedures did slightly better than right. Non-participation reasons- 20/30 lack of time, 7/30- reduced internet access, 3/30- non specified. Conclusions. Our results suggest improvement in PROMS. Better outcomes are linked to increased age, male sex, left sided procedures but not individual surgeons. Non-responding patients placed forgetfulness/time and lack of Internet access as reasons for non-participation Simplification and integration of PROMS will be key to increased participation.

Background. The goal of total hip arthroplasty (THA) is to reduce pain, restore function but also activity levels for general health benefits or social participation. Thus evaluating THA patient activity can be important for diagnosis, indication, outcome assessment or biofeedback. Methods. Physical activity (PA) of n=100 primary THA patients (age at surgery 63 ±8yrs; 49M/51F; 170 ±8cm, 79.8 ±14.0kg) was measured at 8 ±3yrs follow-up. A small 3D accelerometer was worn for 4 successive days during waking hours at the non-affected lateral upper leg. Data was analysed using validated algorithms (Matlab) producing quantitative (e.g. #steps, #transfers, #walking bouts) and qualitative (e.g. cadence, temporal distribution of events) activity parameters. An age matched healthy control group (n=40, 69 ±8yrs, 22M/18F) served as reference. Results. Daily steps were only 13% lower (n.s) for patients (avg. ±SD: 5989 ±3127) than controls (6890 ±2803). However, the Nr. of walking bouts (187 ±85 vs 223 ±78, −16%) and sit-stand transfers (35 ±14 vs 48 ±15, −27%) were sign. less in patients (p<0.05, Mann-Whitney). Patients showed equal amounts of walking bouts in medium duration (30-60s, 1–5min) but sign. less (−25%) short (<10s, 10–30s) and less (−43%) long events (>5min). This corresponds with sign. less (−32%) short sitting periods (>10min) in patients. Also cadence was sign. lower in patients (93.8 ±11.7 vs 98.9 ±7.3 steps/min). Conclusions. PA varies widely in patients with a substantial proportion (35%) being more active than average controls. Thus, THA must not per se reduce or limit PA. Only 17% of controls and 11% of patients reached the WHO target (10,000 steps/day) suggesting that the THA related drop in activity may inflate the risks for cardiovascular, metabolic or mental disease associated with low activity. Patients avoided short and long activities, both associated with effort. Targeted interventions may address this behaviour
