Cement-in-cement revision of the femoral component represents a widely practiced technique for a variety of indications. In this study we compare the clinical and radiological outcomes of two polished tapered stems.

From our prospectively collated database we identified all patients undergoing cement-in-cement revision from January 2005 – 2013 who had a minimum of two years follow-up. All cases were performed by the senior author using either an Exeter short revision stem or the C-stem AMT high offset No 1. Patients were followed-up annually with clinical and radiological assessment.

Ninety-seven patients matched the inclusion criteria. There were 50 Exeter and 47 C-stem AMT components. There were no significant differences between the patient demographics in either group. Mean follow-up was 9.7 years. A significant improvement in OHS, WOMAC and SF-12 scores was observed in both cohorts. Leg lengths were significantly shorter in the Exeter group, with a mean of -4mm in this cohort compared to 0mm in the C-stem AMT group. One patient in the Exeter group had early evidence of radiological loosening. In total, 16 patients (15%) underwent further revision of the femoral component (seven in the C-stem AMT group and nine in the Exeter group). No femoral components were revised for aseptic loosening. There were two cases of femoral component fracture in the Exeter group.

Our series shows promising long-term outcomes for the cement-in-cement revision technique using either the Exeter or C-stem AMT components. These results demonstrate that cement-in-cement revision using a double or triple taper-slip design is a safe and reliable technique when used for the correct indications.

Necrotizing Fasciitis (NF) is a life-threatening infectious condition which requires expedient diagnosis to proceed with urgent surgical debridement. However, it can be difficult to establish an early diagnosis and expedite operative management as signs and symptoms are often non-specific and may mimic other pathology. Scoring systems such as The Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) have been proposed to incorporate laboratory findings to predict whether a soft tissue infection is likely to be NF. Recent studies have found the sensitivity and specificity of the LRINEC tool to be lower than originally cited by the LRINEC authors in a validation cohort. Furthermore, there seems to be a predilection for certain geographic locations of patients with NF transferred to our tertiary care center for management, however, to our knowledge, geographic risk factors for NF have not been reported. This study also aims to determine the morbidity and mortality rate of NF at our Canadian tertiary hospital in recent years.

Comorbidities such as smoking, diabetes, and steroid use will be analyzed for any correlation with developing NF. Identification of patient factors in correlation with laboratory values may help identify patients at higher risk for having NF upon their presentation to the emergency department. A resultant earlier diagnosis of necrotizing soft tissue infections would allow for earlier surgical debridement and positively influence patient outcomes.

A retrospective chart review of 125 cases of NF at Kingston Health Sciences Centre from 2005 to 2017 was carried out to assess the validity of the LRINEC in our population and to examine the effect of comorbid factors such as smoking, diabetes, and corticosteroid use on the development of NF. The study cohort included patients treated by all surgical disciplines at our institution over twelve years. A separate cohort of 125 cellulitis or abscess cases was analyzed to assess the validity of the LRINEC tool in differentiating necrotizing fasciitis from non-necrotizing infections such as cellulitis and soft tissue abscess.

The 30-day mortality rate of NF treated at our institution during the study period was 21%. Advanced age was found to be a significant risk factor for death within 30 days of diagnosis (p=0.001). Smoking and steroid use were both found to increase risk for developing NF (p=0.01 and p=0.03, respectively). Diabetes did not appear to increase risk NF. There was no statistical difference in mortality rates between males and females with NF. The sensitivity of LRINEC in detecting NF was only 47% with a specificity of 74%.

The mortality rate of NF at our center is similar to that of other countries in recent years. Males and females have nearly equal mortality rates from NF. Smoking and steroid use appear to increase risk for developing NF, while diabetes may not. The LRINEC assessment tool alone may underestimate risk for developing NF, however, use of other clinical factors such as comorbidity analysis will further aide in the diagnosis of NF allowing for earlier surgical debridement.

Introduction

Cement in cement revision with preservation of the original cement mantle has become an attractive and commonly practised technique in revision hip surgery. Since introducing this technique to our unit we have used two types of polished tapered stem. We report the clinical and radiological outcomes for cement in cement femoral revisions performed using these prostheses.

Ganz peri-acetabular osteotomy is commonly used to treat symptomatic hip dysplasia. It aims to increase the load bearing contact area of the hip to reduce the risk of subsequent osteoarthritis. In this study we assess the radiographic and clinical results of the procedure since its introduction to our unit.

All patients undergoing Ganz osteotomies at our unit were followed up prospectively. Data collected included patient demographics and pre- and post-operative functional scores (Harris and Non-arthritic hip scores). In addition, acetabular correction was evaluated on pre-and post-operative radiographs (using Centre-Edge angle and Tonnis angle). Complications were also noted.

Overall 50 procedures were performed between 2007 and 2013 with median follow-up of 3 years (1 – 7 years). The majority of patients (90%) were female. Average age at time of surgery was 29 years (16–49). There were significant improvements in pre- and post-operative median functional scores (Modified Harris Hip Score = 49 versus 64, p=0.001), Non-arthritic Hip Score = 42 versus 56, p=0.007). Median Centre Edge Angle improved from 16 degrees pre-operatively (range = 7–31 degrees) to 30 degrees post-operatively (18–33) degrees), p<0.0001. Similarly, pre-operative Tonnis angle improved from 18 degrees (9–38) to 7 degrees (2–14), p<0.0001. Five patients developed post-operative complications: 2 superficial wound infection, 1deep infection requiring hip washout and antibiotic treatment and 2 patients subsequently requiring total hip replacements.

We have shown that the Ganz peri-acetabular osteotomy can be effective for the treatment of painful hip dysplasia improving both functional and radiographic outcomes. However, patient selection is a key factor.

Postgraduate training in orthopaedics has traditionally been delivered through an apprenticeship model. However, junior doctor working patterns have more recently moved away from a team based structure, potentially affecting training experience. We aimed to compare the perceived quality of training between medical students, junior non-orthopaedic trainees and orthopaedic specialty trainees.

We conducted an anonymous questionnaire of all medical students and trainees rotating through our unit over 24 months. The questionnaire contained 6, 10-point Likert rating scale questions and free text responses. Results were collated and analysed according to training stage.

Of 82 questionnaires distributed, 60 (73%) were completed (18 specialty registrars, 22 junior trainees and 20 medical students). Junior trainees consisted of 8 GPSTs and 14 Foundation Year (FY2) doctors, only one of whom had specifically chosen an orthopaedic placement.

Median Likert rating of training experience was (1 = very poor, 10 = excellent): ST4-ST8 = 8 (range 7–9), ST1-ST3 = 7 (6–9), GPSTs/FY2s = 4 (2–5) and medical students = 8 (7–10). Further analysis of junior non-orthopaedic doctors' training experience showed that placement induction, organisation of formal teaching and opportunities for training out with formal sessions were rated as poor. However, content of delivered teaching was rated highly. Free text responses identified several barriers to training including being too busy on wards and no opportunity for protected teaching.

Our study shows that junior non-orthopaedic trainees feel their training experience during orthopaedic placements is much poorer than orthopaedic trainees and medical students. Time constraints and less team based working patterns may detract from their teaching opportunities. In addition, junior doctors rotating through orthopaedic units now have a wider spectrum of career interests with heterogeneous training needs. Therefore, orthopaedic departments may need to adopt a more targeted training programme that recognises individual training needs if junior doctor training is to improve.

Successful treatment of periprosthetic joint infection involves surgical intervention and identification of infecting organisms to enable targeted antibiotic therapy. Current guidelines recommend intra-operative culture sampling to include at least 4 tissue samples and for each sample to be taken with a separate instrument.

We aimed to review current revision arthroplasty practice for Greater Glasgow, specifically comparing intra-operative sampling technique for infected revision cases with these guidelines.

We reviewed the clinical notes of all patients undergoing lower limb revision arthroplasty procedures in Greater Glasgow Hospitals (WIG, GRI, SGH) from July 2013 to August 2014. Demographics of all cases were collected. For revision procedures performed for infection we recorded details of intraoperative samples taken (number, type and sampling technique) and time for samples to reach the laboratory. Results of microbiology cultures were reviewed.

Two hundred and fifty five revision arthroplasty procedures (152 hips, 103 knees) were performed in the 12 month study period. Of these 57 (22%) were infected cases (28 hips, 29 knees). These cases were treated by 14 arthroplasty surgeons with a median number of 3 infected cases managed per surgeon (range 1–11). 58% of cases had the recommended number of tissue samples taken. The median number of microbiology samples collected was 4 (range 1–14). Most procedures (91%) had no documentation of whether separate instruments were used for sampling. Number of tissue samples taken (≥4, p=0.01), time to lab (<24 hours, p=0.03) were significantly associated with positive culture results.

In Greater Glasgow, a large number of surgeons manage infected arthroplasty cases with variability in intra-operative sampling techniques. Sample collection adheres to guideline recommendations in 58% cases. Adhering to guideline standards increases the likelihood of positive tissue cultures. Implementation of a standardised approach to intra-operative sampling for infected cases may improve patient management.

Introduction:

Primary functions of heel and forefoot fat pad - shock absorber at heel strike, energy dissipation, load bearing, grip and insulation. •Reliability of weight bearing heel pad thickness measurements by ultrasound has been determined by Rome et al. Importance of soft tissue fillers has been recently popularised by Coleman.

Ganz peri-acetabular osteotomy is commonly used to treat symptomatic hip dysplasia. It aims to increase the load bearing contact area of the hip to reduce the risk of subsequent osteoarthritis. In this study we assess the radiographic and clinical results of the procedure since its introduction to our unit.

All patients undergoing Ganz osteotomies at our unit were followed up prospectively. Data collected included patient demographics and pre- and post-operative functional scores (Harris and Non-arthritic hip scores). In addition, acetabular correction was evaluated on pre-and post-operative radiographs (using Centre-Edge angle and Tonnis angle). Complications were also noted.

Overall 50 procedures were performed between 2007 and 2013 with median follow-up of 3 years (1–7 years). The majority of patients (90%) were female. Average age at time of surgery was 32 years (17–39). There were significant improvements in pre- and post-operative median functional scores (Modified Harris Hip Score = 52 versus 63, p=0.001), Non-arthritic Hip Score = 49 versus 60, p=0.01). Median Centre Edge Angle improved from 15 degrees pre-operatively (range = 8–19 degrees) to 29 degrees post-operatively (22–36 degrees), p=0.02. Similarly, pre-operative Tonnis angle improved from 19 degrees (16–38) to 7 degrees (2–14), p=0.01. Four patients developed post-operative complications: 1 superficial wound infection, 1deep infection requiring hip washout and antibiotic treatment and 2 patients subsequently requiring total hip replacements.

We have shown that the Ganz peri-acetabular osteotomy can be effective for the treatment of painful hip dysplasia improving both functional and radiographic outcomes. However, patient selection is a key factor.

When performing total hip replacements in patients with hip dysplasia, acetabular augmentation may be required to prevent early component failure. Preoperative radiographic templating may help estimate acetabularcomponent coverage but has not previously been shown to predict the need for augmentation.

We developed a simple method to estimate the percentage of acetabular component coverage from pre-operative radiographs (True: False cup ratio). We aimed to evaluate whether this couldpredict the need foracetabular augmentation at primary total hip replacement for patients with dysplastic hips.

We reviewed all patients with hip dysplasia who underwent a primary total hip replacement from 2005–2012. Classification of hip dysplasia (Crowe), centre edge angle (CEA), Sharp and Tonnis angles were determined on pre-operative radiographs for each patient. Templating was performed on anteroposteriorand lateral view hip radiographs to determine the likely percentage of acetabular component coverage using the True: False cup ratio. Patients requiring acetabular augmentation at time of primary total hip arthroplasty were noted.

128 cases were reviewed, 31 (24%) required acetabularaugmentation. Comparison between augmented and non-augmented cases revealed no difference in the mean CEA (p = 0.19), Sharp angles (p = 0.76) or Tonnis angles (p = 0.32). A lower True Cup: False Cup ratio was observed in the augmented groupcompared to the non-augmented group(median = 0.68 vs 0.88, p < 0.01).

Preoperative templating can help predict which dysplastic hips are likely to require acetabular augmentation at primary total hip replacement.

When performing total knee replacement (TKR), surgeons must select a size of tibial component tray that most closely matches the anatomy of the proximal tibia. As implants are available in a limited range of sizes, it may be necessary to slightly under or oversize the component. There are concerns overhang could lead to pain from irritation of soft tissues, and underhang could lead to subsidence and failure.

154 TKRs at 1- or 5-year follow up were reviewed prospectively. Oxford Knee Score (OKS), WOMAC and SF-12 was recorded along with pain scores. Scaled radiographs were reviewed and grouped into perfect sizing (78 TKRs, 50.6%), underhang in isolation (48 TKRs, 31.1%), minor overhang 1–3 mm (10 TKRs, 6.49%) or major overhang >3 mm (18 TKRs, 11.7%).

There was no significant difference in the SF-12 (p=0.356), post-operative OKS (p=0.401) or WOMAC (p=0.466) score. For the OKS, there was no difference for the scores collected at 1 year (p=0.176) or at 5 years (p=0.883).

Pre-operative OKS was well matched between the groups (p=0.152). There was no significant difference in the improvement in OKS from pre-operative scores (p=0.662). There was no significant difference in either the OKS or WOMAC pain scores (p=0.237 and 0.542 respectively).

There was no significant association of medial overhang with?medial knee pain (p=1.000) or lateral overhang with lateral knee pain (p=0.569) when compared to the group of patients with a well sized tibial component.

Our results suggest that tibial component overhang or underhang has no detrimental affect on outcome or pain scores. Surgeons should continue to select the tibial component that most closely fits the rim of the proximal tibia while accepting slight overhang if necessary due to the potential longer-term complications of subsidence and premature failure with an undersized tibial tray.

Neurological examination in children presenting with upper limb fractures is often poorly performed. We aimed to assess the quality of documented neurological examination in children presenting with upper limb fractures and whether this could be improved following introduction of a simple guideline for paediatric neurological assessment.

We reviewed the clinical notes of all children presenting to the emergency department with upper limb fractures over a three month period. Documentation of initial neurological assessment and clinical suspicion of any nerve injury were noted. Subsequently, we introduced a guideline for paediatric upper limb neurological examination (‘Rock, Paper, Scissors, OK’) to our own hospital and performed a further 3 month clinical review to detect any resulting change in practice.

In the initial study period, 121 patients presented with upper limb fractures. 10 children (8%) had a nerve injury. Neurological examination was documented in 107 (88%) of patients, however, none of the nerve injuries were detected on initial assessment. In patients with nerve injuries, 5 (50%) were documented as being ‘neurovascularly intact’ and 2 (20%) had no documented examination.

Following introduction of the guideline, 97 patients presented with upper limb fractures of which 8 children (8%) had a nerve injury. Documentation of neurological examination increased to 98% for patients presenting directly to our own hospital (p=0.02). Within this cohort all nerve injuries with objective motor or sensory deficits were detected on initial examination.

Introduction of a simple guideline for neurological examination in children with upper limb fractures can significantly improve the quality of documented neurological assessment and detection of nerve injuries.

Neurological examination in children presenting with upper limb fractures is often poorly performed. In the peripatetic emergency department environment this may be confounded by patient distress or reduced comprehension. We aimed to assess the quality of documented neurological examination in children presenting with upper limb fractures and whether this could be improved following introduction of a simple guideline for paediatric neurological assessment.

We reviewed the clinical notes of all children presenting to the emergency department with upper limb fractures over a three month period. Documentation of initial neurological assessment and clinical suspicion of any nerve injury were noted. Subsequently, we introduced a guideline for paediatric upper limb neurological examination (‘Rock, Paper, Scissors, OK’) to our hospital and performed a further 3 month review to detect resulting changes in practice.

In the initial study period, 121 children presented with upper limb fractures. 10 (8%) had a nerve injury. Neurological examination was documented in 107 (88%) of patients. However, information on nerves examined was only recorded in 5 (5%) with the majority (85%) documented as ‘neurovascuarly intact’. None of the nerve injuries were detected on initial assessment.

Following guideline introduction, 97 patients presented with upper limb fractures of which 8 children (8%) had a nerve injury. Documentation of neurological examination increased to 98% for patients presenting directly to our own hospital (Fisher's Exact Test, p=0.02) with details of nerves examined increasing to 69%. Within this cohort all nerve injuries with objective motor or sensory deficits were detected on initial examination.

The recent British Orthopaedic Association Standards for Trauma (BOAST) guideline on peripheral nerve injuries emphasises the importance of clearly recorded neurological assessment in trauma patients. Our study shows that introduction of a simple guideline for neurological examination in children with upper limb fractures can significantly improve the quality of documented neurological assessment and detection of nerve injuries.

Repeat revision hip replacements can lead to severe bone loss necessitating salvage procedures such as proximal or total femoral replacement. We present medium term outcomes from our experience of the Limb Preservation System (LPS) in patients with failed revision hip arthroplasties.

All patients undergoing proximal femoral or total femoral replacement from 2003–2007 at our unit were reviewed. Data was collected preoperatively and at annual assessment post procedure for a minimum of 5 years. This included clinical review, functional outcome scores (WOMAC, Oxford Hip Score, Harris Hip Score) and radiographic evaluation.

A total of 17 patients underwent femoral replacement (13 proximal, 4 total) using the LPS during the study period. Within this cohort there were 13 males and 4 females with a mean age of 64 years (range 47–86). Median follow up was 7 years (range 5–9 years). Primary diagnoses were DDH (7), Primary OA (5), RA (2), proximal femoral fracture (2) and phocomelia (1). Five patients (29%) required further revision surgery for infection (2 patients) or recurrent dislocations (3 patients). No stems required revision due to aseptic loosening or stem failure at 5–9 years. Compared to preoperative assessment, there was significant improvement in median outcome scores at 5 years (WOMAC increased by 33 points, Oxford hip score by16 points and Harris hip score by 43 points). 82% of patients maintained functional independence at latest review.

The Limb Preservation System offers a salvage procedure for failed revision total hip arthroplasty with significant symptom and functional improvement in most patients at medium term follow up.

Although most peripheral nerve sheath tumours are benign, some are malignant. The management of malignant tumours usually involves wide excision and is facilitated by knowledge of the diagnosis prior to operation. Imaging modalities, including MRI, give anatomical information but do not distinguish between benign and malignant nerve tumours. We therefore introduced the use of ultrasound guided needle biopsy for suspected nerve tumours to our unit in 2004. Prior to this, excision biopsy was carried out in all cases. We aimed to review our experience with needle biopsy and determine whether it has an effective role in the management of peripheral nerve tumours.

All patients who had a needle biopsy for suspected peripheral nerve tumours from January 2004 to December 2011 were identified from our tumour database and clinical notes reviewed. In all cases, biopsy was carried out under ultrasound guidance with local anaesthesia to obtain a 1mm core of tissue.

From 25 patients reviewed, 21 (84%) had a successful biopsy. In 3 cases the biopsy was unable to be completed due to pain and in 1 patient insufficient tumour tissue was obtained. 1 patient had a temporary radial nerve palsy following needle biopsy which recovered fully.

In biopsies that were successful, 19 (90%) showed a benign peripheral nerve tumour. Following diagnosis of a benign lesion, only 2 patients required to have surgical excision of the tumour due to pain. The remainder were managed non-operatively.

In the 2 cases of malignant tumours detected by biopsy, a successful wide surgical excision was performed.

Ultrasound guided core needle biopsy appears safe and gives a tissue diagnosis in most cases of suspected peripheral nerve tumours. In malignant cases it facilitates surgical planning, while most benign tumours could be managed non-operatively, therefore avoiding potential complications of nerve surgery.

Neurological examination is essential in patients with upper limb injuries and should be clearly documented. We aimed to assess the quality and documentation of neurological examination performed for children presenting with upper limb fractures to the emergency department.

Clinical notes of all children admitted with upper limb fractures over a three month period were reviewed. Documentation of initial neurological assessment was analysed and clinical suspicion of any nerve injury noted. In parallel, we conducted an anonymous survey of emergency doctors evaluating their upper limb neurological examination in children.

The casenotes of 121 children with upper limb fractures were reviewed. 10 children (8%) had a nerve injury (median = 4, ulnar = 2, radial = 2, anterior interosseous = 2). Neurological examination was documented in 107 (88%) of patients. However, none of the nerve injuries were detected on initial examination. In patients with nerve injuries, 5 (50%) were documented as being ‘neurovascularly intact’, 2 (20%) as ‘CSM normal’, 1 (10%) as ‘moving fingers’ and 2 (20%) had no documented neurological examination.

30 emergency doctors completed the questionnaires (5 consultants, 9 registrars, 16 foundation doctors). All doctors stated that they routinely performed an upper limb neurological examination and assessed median, ulnar and radial nerves. However, 30% of doctors described incomplete examination of median nerve function, 30% inadequate ulnar nerve assessment and 50% incomplete radial nerve examination. In addition, 75% of doctors failed to identify the need for assessment of anterior interosseous nerve function.

While emergency doctors recognise the importance of neurological assessment in children with upper limb injuries, it is often performed inadequately. This in part may be due to difficulties performing neurological examination in paediatric patients. As a result of this study, we have introduced local guidelines to assist neurological assessment in children.

Objectives

to evaluate effect of a dedicated ward for patients with fractured neck of femur on length of acute bed stay and 30 days mortality rate.

Current fracture-clinic models, especially in the advent of reductions in junior doctors hours, may limit outpatient trainee education and patient care. We designed a new model of fracture-clinic, involving an initial consultant led case review focused on patient management and trainee education.

Prospective outcomes for all new patients attending the redesigned fracture-clinic over a 3-week period in 2010 (n=240) were compared with the traditional clinic in the same period in 2009(n=296). Trainees attending the fracture clinic completed a Likert questionnaire (1 [strongly dissagree] − 5 [strongly agree]) assessing the adequacy of education, support, staff morale & standards of patient care.

The percentage of cases given consultant input increased significantly from 33% in 2009 to 84% in 2010 (p< 0.0001), while the proportion of patients requiring physical review by a consultant fell by 21% (p< 0.0001). Return rates were reduced by 14.3% (p< 0.013) & utilization of the nurse lead fracture clinic improved by 10.1% (p< 0.0028). These improvements were most marked in the target group ?StR2 (24.2% & 22.3% respectively). There were significant improvements in staff perception of their education from 2 to 4.75 (p< 0.0001), provision of senior support from 2.38 to 4.5 (p=0.019), morale from 3.68 to 4.13 (p=0.0331) & their overall perception of patient care from 3.25 to 4.5 (p=0.0016). A&E staff found the new style clinic educational, practice changing & that it improved interdisciplinary relations, but did not interfere with their A&E duties.

Our model of fracture-clinic redesign has significantly enhanced consultant input into patient care without additional funding. In addition, we have demonstrated increased service efficiency and significant improvements in staff support, morale and education. In the face of current economic and training challenges, we recommend this new model as a tool for enhancing patient and trainee experiences.

The National Institute of Clinical Excellence (NICE) published guidance for reducing the risk of venous thromboembolism (VTE) in January 2010. This guidance has had a significant impact on the management of all inpatients. It is now mandatory to risk assess every inpatient and commence appropriate treatment if indicated. The guidelines specifically exclude outpatients although NICE recognises' that lower limb cast immobilisation is a risk factor for VTE. The purpose of our study was to establish the current practice for the management of outpatients treated with lower limb casts in England.

The NHS Choices website lists 166 acute hospitals in England. A telephone audit was conducted in February 2011. A member of the on call orthopaedic team was asked: 1. Are you aware of the NICE guidelines for VTE prophylaxis? 2. In your department, outpatients treated with a lower limb cast, are they risk assessed for VTE? 3. If a patient undergoes Open Reduction Internal Fixation (ORIF) for an ankle fracture and is discharged wearing a cast, are they given VTE prophylaxis? 4. If yes - for how long are they treated?

Responses were obtained from 150 eligible hospitals (1 FY1, 28 FY2, 44 ST1-ST2, 76 ST3+, 1 Consultant). 62% of responders stated that they were aware of the NICE guidance. 40% of responders stated that outpatients were routinely risk assessed for VTE. 32% of responders stated that ankle fractures treated with an ORIF and discharged wearing a cast would receive VTE prophylaxis. The duration of treatment varied from 5 days, to 6 weeks, to removal of cast.

The management of patients treated with a lower limb cast is variable and inconsistent throughout England. Although there are no national guidelines for this patient group, the routine risk assessment of outpatients was higher than anticipated by the authors. We recommend that if VTE prophylaxis is commenced as an inpatient, then it should be continued until the cast is removed.

Current fracture-clinic models, especially in the advent of reductions in junior doctors hours, may limit outpatient trainee education and patient care. We designed a new model of fracture-clinic, involving an initial consultant led case review focused on patient management and trainee education.

Outcomes for all new patients attending the redesigned fracture-clinic over a 3-week period in 2010 were compared with the traditional clinic in the same period in 2009. Health professionals completed a Likert questionnaire assessing their perceptions of education, support, standards of patient care and morale before and after the clinic redesign.

309 and 240 patients attended the clinics in 2009 and 2010 respectively. There was an increase in consultant input into patient management after the redesign (29% versus 84%, p<0.0001), while the proportion of patients requiring physical review by a consultant fell (32% versus 9%). The percentage of new patients discharged by junior medical staff increased (17% versus 25%) with a reciprocal fall in return appointments (55% versus 40%, p<0.0005). Overall, return appointment rates fell significantly (55% versus 40%, p=0.013). Staff perception of education and senior support improved from 2 to 5, morale and overall perception of patient care from 4 to 5.

Our model of fracture-clinic redesign has significantly enhanced consultant input into patient care without additional funding. In addition, we have demonstrated increased service efficiency and significant improvements in staff support, morale and education. In the face of current economic and training challenges, we recommend this new model as a tool for enhancing patient and trainee experiences.

Post-operative regimes involving the use of intra-articular local anaesthetic infiltration may allow early mobilisation in patients undergoing total knee arthroplasty. Few studies have evaluated such regimes outside specialist arthroplasty units. We aimed to determine whether an enhanced recovery programme including the use of local anaesthetic administration could be adapted for use in a district general setting.

Following introduction of this regime to our unit, 100 consecutive patients undergoing primary total knee arthroplasty were reviewed. 56 patients underwent a standard analgesic regime involving a general or spinal anaesthetic and oral analgesics post operatively (group1). 48 patients underwent the newly introduced regime, which included pre-operative counselling, peri-articular local anaesthetic infiltration at operation and intra-articular local anaesthetic top-up administration post-operatively for 24 hours (group 2). Length of stay, post-operative analgesic requirements, and range of knee motion post-operatively were compared.

Median length of stay was less for patients in group 2 compared with those in group 1 (4 days compared to 5 days, p<0.05). Patients in group 2 required lower total doses of opiate analgesia post-operatively. 90% of patients in group 2 were ambulant on the first post operative day, compared with less than 25% of patients in group 1. Mean knee flexion on discharge was greater in patients in group 2 compared with those in group 1 (85 degrees compared with 75 degrees). No infective complications from intra-articular catheter placement were observed. However, technical difficulties were encountered during the introduction period, including loss of catheter placement, leakage of local anaesthetic and adaptation of nursing time for top-up anaesthetic administration.

A rehabilitation regime involving local anaesthetic infiltration for total knee arthroplasty can successfully be adapted for use in a district general setting. Our results suggest if initial technical difficulties are overcome, this regime can provide effective postoperative analgesia, early mobilisation and reduced hospital stay.
