This study aims to determine satisfaction rates after hip and knee arthroplasty in patients who did not initially respond to PROMs, characteristics of non-responders, and contact preferences to maximise response rates. We performed a prospective cohort study of 709 patients undergoing THA and 737 patients undergoing TKA in a single centre in 2018. EQ-5D health related quality of life score and Oxford Hip/knee scores (OHS/OKS) were completed preoperatively and at 1year postoperatively via post when satisfaction was also assessed. Univariate, multivariate and receiver operator curve analysis were performed. 151/709 (21.2%) hip patients were non-responders, 83 (55.0%) of whom were contactable. 108/737 (14.6%) knee patients were non-responders, 91 (84.3%) of whom were contactable. There was no difference in satisfaction after arthroplasty between initial non-responders and responders for hips (74/81 vs 476/516, p=0.847) or knees (81/93 vs 470/561, p=0.480). Initial and persistent non-response was associated with younger age, higher BMIs and significantly worse preoperative PROMS for both hip and knee patients (p=0.05). Multivariate analysis demonstrated that younger age, higher BMI and poorer pre-operative OHS were independently associated with persistent non-response to hip PROMs (p<0.05). For the entire cohort (n=1352) patients <67 years were less likely to respond to postal PROMs with OR 0.63 (0.558 to 0.711). Using a threshold of >66.4 years predicted a preference for contact by post with 65.4% sensitivity and 68.1% specificity (AUC 0.723 (0.647-0.799 95%CI, p<0.001)). Most initial non-responders were ultimately contactable with effort. Satisfaction rates were not inferior in patients who did not initially respond to PROMs

One potential approach to addressing the current hip and knee arthroplasty backlog is via adoption of surgical prioritisation methods, such as use of pre-operative health related quality of life (HRQOL) assessment. We set out to determine whether dichotomization using a previously identified bimodal EuroQol Five-Dimension (EQ-5D) distribution could be used to triage waiting lists. 516 patients had data collected regarding demographics, perioperative variables and patient reported outcome measures (pre-operative & 1-year post-operative EQ-5D-3L and Oxford Hip and Knee Scores (OHS/OKS). Patients were split into two equal groups based on pre-operative EQ-5D Time Trade-Off (TTO) scores and compared (Group1 [worse HRQOL] = −0.239 to 0.487; Group2 [better HRQOL] = 0.516 to 1 (best)). The EQ5D TTO is a widely used and validated HRQOL measure that generates single values for different combinations of health-states based upon how individuals compare x years of healthy living to x years of illness. We identified that those in Group1 had significantly greater improvement in post-operative EQ-5D TTO scores compared to Group2 (Median 0.67vs.0.19; p<0.0001 respectively), as well as greater improvement in OHS/OKS (Mean 22.4vs16.4; p<0.0001 respectively). Those in Group2 were significantly less likely to achieve EQ-5D MCID attainment (OR 0.13, 95%CI 0.07–0.23; p<0.0001) with a trend towards lower OHS/OKS MCID attainment (OR 0.66, 95%CI 0.37–1.19; p=0.168). There was no statistically significant difference in adverse events. These finding suggest that a pre-operative EQ-5D cut-off of ≤0.487 for hip and knee arthroplasty prioritisation may help to maximise clinical utility and cost-effectiveness in a limited resource setting post COVID-19

NICE guidelines state that patients undergoing hip or knee arthroplasty should start as an in-patient and then continue pharmacological VTE prophylaxis for 28–35 days. Retrospective review of all elective hip and knee arthroplasties during one calendar month gave a baseline measurement of how many patients had VTE prophylaxis prescribed on their discharge summary. A new, electronically completed, bespoke Trauma and Orthopaedic discharge summary was created with a discreet area clearly marked for VTE prophylaxis, to serve as a reminder to prescribe it. In March 2012, 93 patients underwent hip/knee arthroplasty. 76% (71/93) were prescribed VTE prophylaxis to take home, there was no clinical reason explaining the failure to prescribe prophylaxis in the remaining 24%. In July 2013, after implementation of the change, 117 patients underwent hip/knee arthroplasty. 99% (116/117) were prescribed VTE prophylaxis to take home. Repeat audit in October 2013 showed that 103 patients underwent hip/knee arthroplasty and 100% were prescribed VTE prophylaxis. A simple but clear change to paperwork, brought about a rapid and seemingly lasting change in the prescription of out-patient VTE prophylaxis. The improvement was seen before and after a change of the Junior Doctor workforce suggesting the change in documentation was the main influencing factor

Clostridium difficile is associated with a range of gastrointestinal disorders ranging from diarrhoea to toxic megacolon. Alteration of the normal gut flora by antibiotics is a key predisposing factor. Although antibiotic prophylaxis is routinely administered during joint replacement surgery, there has been controversy about both type and duration of prophylaxis. The primary aim of this study was to determine the incidence of C. diff associated disease (CDAD) following hip and knee replacement and to investigate potential risk factors. A laboratory database was interrogated to identify patients developing CDAD after hip or knee replacement from January 2006 to December 2008. A database of arthroplasty patients was used to identify a control group of patients without CDAD to compare the effects of prescription of antibiotics for reasons other prophylaxis of deep infection, comorbidity and the use of gastroprotective agents. Eight patients developed CDAD. There were 1.7 cases of CDAD per 1000 joint replacements. Patients developing CDAD were more likely to have been prescribed additional antibiotics (p=0.047). There were no differences in the use of gastroprotective agents (p=0.703). A trial of a new prophylaxis regime would require 43,198 patients in each arm to show a reduction to 1 case per 1000 procedures. Cefuroxime based antibiotic prophylaxis is safe in patients undergoing elective joint replacement. Extremely large studies would be required to show marginal clinical benefits of new regimes. One prophylaxis policy will not suit all orthopaedic patient groups or procedures

The aim was to perform a cost-utility analysis of total joint replacement in the current environment. Arthritis is a disabling condition that leads to long-term deterioration in quality of life. Total joint replacement, despite being one of the greatest advances in medicine in the modern era, has come under recent scrutiny. The National Health Service (NHS) has competing demands and resource allocation is challenging in times of economic restraint. Patients undergoing total hip (n=348) and knee arthroplasty (n=323), from January to July 2010, were entered into a prospective arthroplasty database. A health utility score was derived from the Euroqol (EQ-5D) score preoperatively, and at one year, and was combined with individual life expectancy to derive the Quality-Adujusted-Life-Years (QALYs) gained. Predicted need for revision surgery was Incorporated in the model. The 2011–12 Scottish Tariff was used. Two-way analysis of variance was used to compare QALYs gained between procedures, while controlling for baseline differences. The number of QALYs gained was higher in THR versus TKR (6.53 vs 4.04 years, p<0.001). The cost per QALY for THR was £1371 (95% CI £1194 to £1614) compared with £2101 (£1762 to £2620) for TKR. Predictors of an increase in QALYs gained were poorer health prior to surgery (p<0.001) and younger age (p<0.001). General health (EQ-5D VAS) showed greater improvement in THR versus TKR (p<0.001). This study provides up to date cost-effectiveness data for total joint replacement. THR and TKR are both extremely clinically and cost-effective interventions, with costs that compare favourably with other medical interventions (e.g. laparoscopic hernia repair vs open: £55,548 per QALY; CHD primary prevention with statins: £21,000)

SIGN guidelines advise the use of flucloxacillin and gentamicin instead of cefuroxime as antibiotic prophylaxis for elective hip and knee arthroplasty. It is our impression that this change in practice has been associated with an increased risk of acute kidney injury (AKI). During a twelve month period we examined the incidence of AKI sequentially in four groups of patients: cefuroxime prophylaxis (n = 46); high dose flucloxacillin (5-8g) with single shot gentamicin (n = 50); low dose flucloxacillin (1-4 g) with single shot gentamicin (n = 45); and finally cefuroxime again (n = 52). There were no statistically significant differences by chi-square tests for age, gender, operation (hip or knee), ASA, anaesthesia, baseline serum creatinine, hypertension, diabetes or pre-operative medication. The proportion of patients in each antibiotic group with any form of AKI by RIFLE criteria was: cefuroxime group 1 (9%), high dose flucloxacillin (52%), low dose flucloxacillin (22%), cefuroxime 2 (14%) (p < 0.0001 by chi-square test). Odds ratios (OR) for AKI derived from a multivariate logistic regression model and assigning an OR of 1 to cefuroxime group 1 was: high dose flucloxacillin 14.5 (95% CI, 4.2, 50.2); low dose flucloxacillin 3.0 (0.8-10.9) and cefuroxime group 2 1.9 (0.5, 7.4). Three patients in the high dose flucloxacillin group required temporary haemodialysis. We have shown a strong association between high dose prophylactic flucloxacillin and subsequent development of AKI. We have no reason to believe that this was confounded by any of the co-variates we measured

Many psychological factors have been associated with function after joint replacement. Personality is a stable pattern of responses to external conditions and stimuli. The aim of this study was to investigate the relationship between personality, joint function, and general physical in patients undergoing total hip (THR) and knee replacement (TKR). We undertook a prospective cohort study of 184 patients undergoing THA and 205 undergoing TKA. Personality was assesed using the Eysneck Personality Questionaire, brief version (EPQ-BV). Physical health was measured using the EuroQol (EQ-5D). Joint function was measured using the relevant Oxford Score. Outcomes were assessed at six months. Multivariable models were constructed. The stable introvert personality was most common. Unstable introverts had poorer pre-operative function with hip arthrosis, but not knee arthrosis. Personality was not directly associated with post-operative function – the only independent predictors were pre-operative function (p=0.002) and comorbidity (p<0.001). While satisfaction after TKR was associated with personality (p=0.026), there was no association after THR (p=0.453). The poorest satisfaction was in those with the unstable introvert personality type. Personality was a predictor of preoperative status. It did not have a direct association with postoperative status, but may have as preoperative function was the main predictor of postoperative function, personality may have had an indirect effect. Personality was also a predictor of satisfaction after TKR. This suggests that predicting satisfaction after knee replacement is more complex. Therefore certain patient may benefit from a tailored preoperative education to explore and manage expectations

The primary aim was to assess whether patients waiting 6-months or more for a total hip (THA) or knee (KA) arthroplasty had a deterioration in their health-related quality of life (HRQoL). Secondary aims were to assess change in level of frailty and the number living in a state worse than death (WTD).

Eight-six patients waiting for a primary TKA or KA for more than 6-months were selected at random from waiting lists in three centres. Patient demographics, waiting time, EuroQol 5-dimension (EQ-5D) and visual analogue scores (EQ-VAS), Rockwood clinical frailty score (CFS) and SF-36 subjective change in HRQoL were recorded at the time of and for a timepoint 6-months prior to assessment. The study was powered to the EQ-5D (primary measure of HRQoL).

There were 40 male and 46 female patients with a mean age of 68 (33 to 91) years; 65 patients were awaiting a THA and 21 a TKA. The mean waiting time was 372 (226 to 749) days. The EQ-5D index deteriorated by 0.222 (95%CI 0.164 to 0.280, p<0.001). The EQ-VAS also deteriorated by 10.8 (95%CI 7.5 to 14.0, p<0.001). CFS progressed from a median of 3 to 4 (p<0.001). The number of patients WTD increased from seven to 22 (p<0.001). Thirty-one(36%) patients felt their HRQoL was much worse and 28 (33%) felt it was somewhat worse.

Patients waiting more than 6-months had a clinically significant deterioration in their HRQoL and demonstrated increasing level of frailty with more than a quarter living in a health state WTD.

Nerve damage is a complication of THA and TKA procedures. The incidence of subclinical nerve injury following arthroplasty is unknown. The aim was to determine the prevalence of asymptomatic nerve deficits in an arthroplasty population group, and the incidence of post-operative changes in nerve function. A Secondary aim was to identify the nature of any deficits. And the association between nerve deficits and history of backache.

A non-randomised prospective series of patients undergoing lower limb arthroplasty for osteoarthritis were studied at a single hospital. The peroneal nerve was investigated using nerve conduction in forty patients. Twenty patients had upper limb testing to differentiate between a polyneuropathy or isolated lower limb neuropathy.

Nerve function deficits were detected in the peroneal nerve in fifteen patients pre-operatively and fifteen post-operatively, of those twelve had A waves detected suggestive of a generalised neuropathy. Ten patients who had upper limb testing had a conduction defect (five had asymptomatic Carpal tunnel). There was a positive correlation between presence of post-operative deficit and age(r=0.389, p=0.013). A negative correlation was found for presence of post-operative A waves and BMI(r=−0.370, p=0.019).

The prevalence of pre-operative subclinical peroneal neuropathy is much higher than expected in this group (37.5%) of arthroplasty patients. There is a strong correlation between presence of post-operative conduction abnormalities and age. There is no relationship between peripheral neuropathy and history of backache or residual post-operative deficit.

Paget's disease of bone (PDB) is the second most common metabolic bone disease. Osteoarthritis (OA) affects one-third of patients with PDB. The incidence of THR (total hip replacement) and TKR (total knee replacement) is 3.1- and 1.7-fold higher in PDB patients compared to non-affected age-matched controls. No large studies or joint registry reports exist describing the outcomes following THR or TKR in patients with PDB.

The objectives of this study were to investigate the outcomes following THR and TKR in patients with PDB using national joint registry data. 144 THR and 43 TKR were identified using the Scottish Arthroplasty Project from 1996–2013.

For THR, the most common early post-operative surgical complications were haematoma formation (1.4%), and surgical site infection (1.4%). The absolute incidence during follow-up of dislocation was 2.8%, and revision hip arthroplasty was performed in 2.8% of cases. Implant survival of the primary prosthesis was 96.3% (CI: 92.8 – 99.8) at 10-years, and patient survival was 50.0% (39.6 – 60.4) at 10-years.

For TKR, the most common early post-operative surgical complication was surgical site infection (2.3%). The absolute incidence during follow-up of revision knee arthroplasty was 4.7%. On survival analysis, implant survival of the primary prosthesis was 94.5% (CI: 87.1 – 100) at 10-years, and patient survival was 38.3% (16.7 – 59.9) at 10-years.

This is the largest reported series of outcomes following primary THR and TKR in patients with PDB. PDB patients are not at increased risk of surgical complications following primary THR or TKR compared to non-PDB patients.

Methicillin Resistant Staphylococcus Aureus (MRSA) screening has reduced rates of MRSA infection in primary total hip (THR) and total knee (TKR) replacements. There are reports of increasing methicillin resistance (MR) in Coagulase Negative Staphylococci (CNS) causing arthroplasty infections. We examined microbiological results of all 2-stage THR/TKR revisions in Tayside from 2001–2010.

72 revisions in 67 patients were included; 30 THRs and 42 TKRs. Mean ages at revision were 89 and 72 years respectively. Male: female ratio 1.4:1.2-year survivorship for all endpoints: 96% in THRs and 88% in TKRs. 5-year survival: 83% and 84% respectively.

The most common organisms were SA (30%) and CNS (29%). Antibiotic resistance was more common amongst CNS. 72% of CNS were resistant to Methicillin versus 20% of SA. 80% of CNS were resistant to Gentamicin OR Methicillin versus 20% of SA. 32% (8/72 cases or 11% overall) of CNS were resistant to BOTH Gentamicin AND Methicillin, the primary arthroplasty antibiotic prophylaxis in our region, versus 4% of SA.

Harris Hip Scores and Knee Society Scores were lower post primary, prior to symptoms of infection in patients who had MR organisms cultured compared with those who had methicillin sensitive organisms. One-year post revision both groups recovered to similar scores.

Our data suggest MR-CNS cause significantly more arthroplasty infections than MRSA. Patients developing MR infections tend to have poorer post-primary knee and hip scores before symptoms of infection fully develop. 32% of CNS causing arthroplasty infections in our region are resistant to current routine primary antibiotic prophylaxis.

Two stage revision for infection is considered the gold standard with a success rate of 80–90%. Overall functional outcomes of these patients are commonly overlooked. There is a trend towards single stage revision to improve functional outcomes.

We examined the functional scores of 2 stage revision for total hip arthroplasty (THR) and total knee arthroplasty (TKR). 72 revisions were identified over 9 years: 30 THR and 42 TKR. Two year survivorship was 96% in THR revision and 88% TKR revision. Five year survival was 83% and 84% respectively. 50 patients (without recurrence of infection) had recorded functional scores at a minimum of 1 year.

The mean Harris-hip score (HHS) of THR was 75 (21 patients) prior to developing symptoms of infection. Once infected, the mean score fell to 46. At 1 year post revision it returned to 77. At 3 years HHS of 78 (12 patients) and at 5 yrs 62 (3 patients).

The mean knee society score (KSS) of TKR was 66 (29 patients) prior to developing symptoms of infection. Once infected, the mean score fell to 34. At 1 year post revision it returned to 73. At 3 years KSS of 76 (16 patients) and at 5 years 62 (10 patients).

We conclude that functional scores of staged revisions of infected THR and TKR return to pre-morbid levels within a year of completing the second stage. Although single stage revision may have a quicker return to function, by 1 year, staged revision has comparable results.

Aims. Femoral periprosthetic fractures are rising in incidence. Their management is complex and carries a high associated mortality. Unlike native hip fractures, there are no guidelines advising on time to theatre in this group. We aim to determine whether delaying surgical intervention influences morbidity or mortality in femoral periprosthetic fractures. Methods. We identified all periprosthetic fractures around a hip or knee arthroplasty from our prospectively collated database between 2012 and 2021. Patients were categorized into early or delayed intervention based on time from admission to surgery (early = ≤ 36 hours, delayed > 36 hours). Patient demographics, existing implants, Unified Classification System fracture subtype, acute medical issues on admission, preoperative haemoglobin, blood transfusion requirement, and length of hospital stay were identified for all patients. Complication and mortality rates were compared between groups. Results. A total of 365 patients were identified: 140 in the early and 225 in the delayed intervention group. Mortality rate was 4.1% at 30 days and 19.2% at one year. There was some indication that those who had surgery within 36 hours had a higher mortality rate, but this did not reach statistical significance at 30 days (p = 0.078) or one year (p = 0.051). Univariate analysis demonstrated that age, preoperative haemoglobin, acute medical issue on admission, and the presence of postoperative complications influenced 30-day and one-year mortality. Using a multivariate model, age and preoperative haemoglobin were independently predictive factors for one-year mortality (odds ratio (OR) 1.071; p < 0.001 and OR 0.980; p = 0.020). There was no association between timing of surgery and postoperative complications. Postoperative complications were more likely with increasing age (OR 1.032; p = 0.001) and revision arthroplasty compared to internal fixation (OR 0.481; p = 0.001). Conclusion. While early intervention may be preferable to reduce prolonged immobilization, there is no evidence that delaying surgery beyond 36 hours increases mortality or complications in patients with a femoral periprosthetic fracture.

Rivaroxaban, an oral direct factor Xa inhibitor was introduced for thromboprophylaxis at the Royal Cornwall Hospital for hip and knee arthroplasty surgery in October 2009. Our aim was to investigate how safely Rivaroxaban could be implemented and how quickly its regular use was established. We identified 140 patients from theatre logbooks who underwent elective total hip and knee joint replacements between October 2009 and March 2010. Patient notes, computer and DVT clinic records data were collected to determine the uptake of the new drug and the incidence of post-operative complications. We compared our chemical thromboprophylactic rates to those recorded at discharge in a 4-month period prior to our study in 2009. In addition we quantified the time needed before a newly introduced drug becomes established in clinical practice. Patients were divided into two groups. Those who received Rivaroxaban were in group A (n=78, 55.7%) and those who received alternative or no chemical thromboprophylaxis constituted group B (n=62, 44.3%). All patients were prescribed TEDs stockings. 10.3% [8/78] of patients in group A suffered wound complications compared with 6.6% [4/62] of group B patients. Within group A we found that 41.1% (n=7) of the documented wound complications were wound ooze. DVTs occurred in both groups, 1 in group A and 2 in group B. 4 patients had postoperative haematemesis, 2 in each group. Group A had 17 (22%) documented complications. A similar number (n=15, 24%) of patients in group B had recorded complications. Our complication rates compared favourably to the RECORD 1–3 pooled study. From January to April 2009, prior to introduction of Rivaroxaban, 51% of all elective hip and knee replacement surgery patients were receiving any chemical thromboprophylaxis on discharge. This increased to 83% following introduction of Rivaroxaban. During the first month of introduction of Rivaroxaban at our hospital, following NICE guideline, 28% of patients who qualified to receive the drug did. This improved to 95% by the time it had been in use by 3 months. The data shows that there is no statistical significance in complications in thromboprophylaxis in elective total hip and knee replacement surgery between Group A and Group B (P-value 0.8941). This shows similar complication rates to the RECORD clinical study and concludes a safe introduction of the drug to our District General Hospital. Patients in Group A had a reduced occurrence of thrombotic events, but an increase in cases of wound ooze when compared to group B. Following the introduction of Rivaroxaban, it took 3 months for 95% of eligible patients for the drug to be NICE compliant. This demonstrated a 3 month run in time for the implementation of this new treatment regime in our hospital

Non-surgical osteoarthritis management includes analgesia escalation to oral opiates; however, tolerance can occur. This study aims to assess analgesic effects of opiate use pre-operatively and whether this influences outcome 1-year post-operatively in patients undergoing total hip/knee arthroplasty (THA/TKA). This prospective study assessed 1487 patients undergoing primary THA (n=729) or TKA (n=758) for osteoarthritis, with 95 respectively reporting pre-operative opiate use >1 month. THA opiate users had significantly higher BMI (p=0.007) and more likely to suffer associated comorbidities. TKA opiate users were significantly younger (p<0.001), with higher BMI (p=0.019) and more likely to suffer associated comorbidities. Pre-operative quality of life (QoL) and joint specific function were significantly worse (Hip EQ-5D 0.17 vs 0.41, p<0.001, OHS 14.6 vs 21.2, p<0.001; Knee EQ-5D 0.27 vs 0.44, p<0.001, OKS 16.4 vs 21.4, p<0.001). Pre-operative pain was significantly worse in those taking opioids (Hip Pain VAS 42.73 vs 50.70, p<0.001; Knee Pain VAS 50.93 vs 53.36, p=0.30). Post-operatively the THA opiate group had significant improvement in EQ-5D (0.175, p<0.001) and OHS (6.5, p<0.001) but were significantly less improved than opiate naïve patients after adjusting for confounding (EQ-5D 0.10, p<0.001; OHS 3.2, p<0.001). TKA opiate group also had significant improvement in EQ-5D (p<0.001) and OKS (p<0.001) but were significantly less (EQ-5D 0.089, p<0.001; OKS 3.9, p<0.001) than opioid naïve patients. Pre-operative opiate use was associated with significantly worse pre-operative QoL, joint specific function and worse subjective pain. Post-operatively, the opiate group had significantly lower improvement in their QoL and joint specific function

Aims

Periprosthetic fractures (PPFs) following hip arthroplasty are complex injuries. This study evaluates patient demographic characteristics, management, outcomes, and risk factors associated with PPF subtypes over a decade.

To validate the Modified Forgotten Joint Score (MFJS) as a new patient-reported outcome measure (PROM) in hip and knee arthroplasty (THR/TKR) against the UK's gold standard Oxford Hip and Knee Scores (OHS/OKS). The MFJS is a new assessment tool devised to provide a greater discriminatory power, particularly in well performing patients. It measures an appealing concept; the ability of a patient to forget about their artificial joint in everyday life. Postal questionnaires were sent out to 400 THR and TKR patients who were 1–2 years post-op. The data collected from the 212 returned questionnaires was analysed in relation to construct and content validity. 77 patients took part in a test-retest repeatability assessment. The MFJS proved to have an increased discriminatory power in high-performing patients in comparison to the OHS and OKS, highlighted by its more normal frequency of distribution and reduced ceiling effects. 30.8% of patients (n=131) achieved excellent OHS/OKS scores of 42–48 this compared to just 7.69% of patients who achieved a proportionately equivalent MFJS score of 87.5–100. The MFJS proved to have an increased test-retest repeatability based upon its intra-class correlation coefficient of 0.97 compared to the Oxford's 0.85. The MFJS provides a more sensitive tool in the assessment of well performing hip and knee arthroplasties in comparison to the OHS/OKS. The MFJS tests the concept of awareness of a prosthetic joint, rather than pain and function and therefore should be used as adjunct to the OKS/OHS

Introduction. Pre-operative patient education prior to hip and knee arthroplasty is thought to be beneficial for patients in general, although the clinical effect is unproven. Pre-operative education is now standard practice in many orthopaedic units, including our own. Anecdotally, we found patients in the private sector to be more satisfied with their education than those in the public sector, despite very similar education programs. We set out to investigate this observation and establish whether there were differences in the perception of educational quality between these groups. Methods. After appropriate power calculation, 60 patients in each group (120 total) were interviewed after hip or knee arthroplasty. Satisfaction with education was assessed on a simple 5 point scale and demographic data including internet access was obtained, as well as Short-Form 12 (SF-12) data to establish physical and mental function. The education program in each group was similar, with written material provided and verbal education given at a single pre-operative session. This included specialist nursing and physiotherapy input. Results were analysed with the chi2 test, Mann-Whitney U test and logistic regression as appropriate, with significance at P<0.05. Results. Overall, there was a high level of satisfaction in both groups but patients in the private sector were significantly more satisfied with their pre-operative education. Significant differences were identified between the groups in provision of written information, provision of internet resources, access to the internet, attendance at education sessions and the mental component score of the SF-12. Logistic regression modelling showed that factors influencing satisfaction rates were interdependent. The relationship between lower SF-12 mental component scores and lower satisfaction rates was linear. Conclusion. Private patients are more satisfied with their pre-operative education than public patients, a disparity which may be due to several demographic and educational factors including lower SF-12 mental component scores. The relationships between these factors are complex and not independent. Satisfaction in the public sector may be improved by improving attendance rates at education sessions. However, public patients may not benefit from advances in education that rely on internet access or computer use. Although the use of the internet and computers in general is gaining support, it may not be as beneficial to patients in the public sector as the private sector. This has implications for service provision and planning in arthroplasty units

Aims

The aim of this study was to describe the demographic details of patients who sustain a femoral periprosthetic fracture (PPF), the epidemiology of PPFs, PPF characteristics, and the predictors of PPF types in the UK population.

Tranexamic Acid (TXA) is widely used to decrease bleeding by its antifibrinolytic mechanism. Its use is widespread within orthopaedic surgery, with level one evidence for its efficacy in total hip and knee replacement surgery; significantly reducing transfusion rates without increased thromboembolic disease. There is limited evidence for its use during hip fracture surgery, and we therefore sought to investigate its effects with a prospective cohort study. We recorded intra-operative blood loss, pre and post-operative haemoglobin and creatinine levels, post-operative complications and mortality in all hip fracture patients over a six month period. During this time, we introduced one gram of TXA into our standardised hip fracture theatre checklist. It was subsequently given to all patients unless contra-indicated. A total of 99 patients were included. 90-day mortality in the control group was 16%, there was no mortality in the TXA group (p<0.05). 14 patients required a transfusion in the control group and 3 in the TXA group (19% vs 11% transfusion rate, 0.36 units RCC vs 0.22 per patient respectively) Mean blood loss was 338 vs 235mls, Haemoglobin drop 23 vs 18g/dl control and TXA groups respectively. We have demonstrated a significantly lower mortality rate with TXA. We have also shown lower rates of transfusion, blood loss and recorded haemoglobin drop with the use of TXA. We intend to continue this study to demonstrate this significantly, and fully clarify the safety profile of TXA in this frail cohort of patients
