The benefits of cell salvage autotransfusion are well reported. There is a common non-evidenced belief amongst revision arthroplasty surgeons that auto-transfusion is potentially contraindicated in infected revisions. The aim is to study the immediate and delayed outcomes of using cell saver on patients undergoing PJI surgery. Prospective cohort service evaluation registered with the local audit department. 20 PJI cases in 18 patients where cell saver was used over a period of 4 years. Intraoperative fluid and tissue samples were taken for culture. Blood culture from salvaged blood pre and post leucodepletion filter were sent for microbiological analysis. Data on type of surgery, blood loss, further allogenic transfusion and SIRS response was collected. Success of infection clearance was assessed using 2019 MSIS ORT. Five patients receiving autologous blood in non-infection cases were used as controls. Mean age for the PJI group was 67.7 years, 67% female. 11 patients (67%) had 1st stage surgery and 5 (25%) underwent 2nd stage whereas 4 patients had single stage surgery. The mean calculated blood loss was 1398 mls (range 400–3000mls). 6 Patients required further allogenic transfusion. 16 patients received blood via a leuco-depletion filter. The same organism grown from tissues was identified in post-filter blood in 8/17 patients (47%). 2/20 have grown a different organism in post-filtered blood, _P.Acne._. 2 patients developed SIRS upon auto-transfusion, however one was thought to be secondary to cementing. The control group had 443 mls mean amount of blood loss and 1 patient developed a SIRS response. 14/20 (70%) patients had successful clearance of infection (tier 1) 2 patients died prior to undergoing 2nd stage. Using cell saver did not impact main outcome of infection clearance in PJI surgery. We would advocate its routine usage whilst avoiding direct collection of heavily contaminated blood

Introduction. Prosthetic joint infection (PJI) is the leading cause of failure of primary and revision hip and knee arthroplasty. It is challenging condition which represents a growing burden on hospital resources. In-patient hospital stay for antibiotic therapy post-operatively is costly and access to out-patient IV therapy (OPAT) varies between regions. In a tertiary referral centre for revision and infection, the suitability and cost-effectiveness of Dalbavancin was reviewed as a “single-shot” therapy following DAIR or revision lower limb arthroplasty for PJI. Methods & Materials. A prospective service evaluation was carried out for consecutive patients treated for PJI of the hip or knee who received Dalbavancin. Treatment was indicated by Consultant Microbiologist advice within an MDT setting where clinical or patient factors made alternative therapies eg. OPAT inappropriate. Service-level data was collected to allow calculation of bed-day savings compared to a traditional 14-day course of IV treatment. Readmission rates to the trust within 30 days were reviewed as a marker of clinical efficacy and safety. Results. 12 patients received dalbavancin for PJI. Mean bed-day saving was 6.9 (SD 3.7) per patient. A total of 83 bed days were saved compared to traditional treatment and there was a modest cost-benefit. There were no adverse reactions noted and no readmissions within 30 days. Discussion. The safety and efficacy of dalbavancin has been demonstrated in recent literature, but the impact that it can have on health-care costs and in-patient burden has not been explored. In addition, the success of out-patient therapy relies on patient engagement. In patients with co-existing cognitive difficulty or alcohol/substance use Dalbavancin offers an attractive alternative. Conclusions. The results of our pilot suggest that IV Dalbavancin is cost-effective as part of the treatment strategy for PJI and can lead to significant bed-day savings, which can assist in patient flow and departmental efficiency

Aims

The aim of this study was to determine both the incidence of, and the reoperation rate for, postoperative periprosthetic femoral fracture (POPFF) after total hip arthroplasty (THA) with either a collared cementless (CC) femoral component or a cemented polished taper-slip (PTS) femoral component.

Aims

Young adults undergoing total hip arthroplasty (THA) largely have different indications for surgery, preoperative function, and postoperative goals compared to a standard patient group. The aim of our study was to describe young adult THA preoperative function and quality of life, and to assess postoperative satisfaction and compare this with functional outcome measures.

Aims

Delirium is associated with adverse outcomes following hip fracture, but the prevalence and significance of delirium for the prognosis and ongoing rehabilitation needs of patients admitted from home is less well studied. Here, we analyzed relationships between delirium in patients admitted from home with 1) mortality; 2) total length of hospital stay; 3) need for post-acute inpatient rehabilitation; and 4) hospital readmission within 180 days.

Introduction. In rheumatoid (RA) patients undergoing total joint arthroplasty, evidence suggests methotrexate should be continued without increase in post-operative infection. Prednisolone increases post-operative infection risk, but cannot be stopped without risk of Addisonian events. Insufficient evidence exists to clarify perioperative biologic agent management. We currently stop biologics 2 weeks prior to operation and reintroduced following wound healing. Patients/Materials & Methods. This service evaluation reviewed infection rates and length of stay in RA patients following lower-limb arthroplasty, on various anti-rheumatoid therapies across a 28-month period. Results. Forty cases were identified: 15% on no anti-rheumatoid treatment, 45% on mono-therapy (8 on methotrexate, 8 on prednisolone, 2 on biologics)) and 40% on combination-therapy. The total population post-operative infection rate was 18% (all superficial wound). Mean length of stay was 8.0 days (SD=6.8). Methotrexate takers had an infection rate of 5% versus 33% in non-methotrexate takers (p=0.017), and a length of stay of 6.5 days versus 9.9 days in non-MTX takers (p=0.005). Prednisolone takers had an infection rate of 37% versus 0% in non-prednisolone takers (p=0.002) and length of stay was 12.0 days versus 4.7 days in non-prednisolone takers days (p=0.006). Biologics takers had similar infection rates of 9% versus 21% in non-biologic takers (p>0.05), and a similar length of stay of 6.6 days versus 8.6 days in non-biologic takers (p>0.05). Discussion. This data supports current evidence that methotrexate should be continued without detriment to infection risk and length of stay. Biologic agents stopped 2 weeks prior to operation appear to have no effect on infection rate and length of stay. Patients on prednisolone should be identified as at a higher risk of infection and should plan for a longer length of stay. Conclusion. Larger scale cohort studies are required to determine whether biologic agents should be continued per-operatively

Aims

To establish the survivorship, function, and metal ion levels in an unselected series of metal-on-metal hip resurfacing arthroplasties (HRAs) performed by a non-designer surgeon.

Aims

Periacetabular osteotomy (PAO) is an established treatment for acetabular dysplasia. It has also been proposed as a treatment for patients with acetabular retroversion. By reviewing a large cohort, we aimed to test whether outcome is equivalent for both types of morphology and identify factors that influenced outcome.

Aims

We have previously demonstrated raised cobalt and chromium levels in patients with larger diameter femoral heads, following metal-on-polyethylene uncemented total hip arthroplasty. Further data have been collected, to see whether these associations have altered with time and to determine the long-term implications for these patients and our practice.

Aims

Despite few good-quality studies on the subject, total hip arthroplasty (THA) is increasingly being performed for displaced intracapsular fractures of the neck of femur. We compared outcomes of all patients with displacement of these fractures treated surgically over a ten-year period in one institution.

Aims

The aim of this retrospective audit was to determine the route of referral or presentation of patients requiring revision following primary total hip arthroplasty (THA).

Aims

Our aim was to report survivorship data and lessons learned with the Corail/Pinnacle cementless total hip arthroplasty (THA) system.

The outcome after total hip replacement has improved with the development of surgical techniques, better pain management and the introduction of enhanced recovery pathways. These pathways require a multidisciplinary team to manage pre-operative education, multimodal pain control and accelerated rehabilitation. The current economic climate and restricted budgets favour brief hospitalisation while minimising costs. This has put considerable pressure on hospitals to combine excellent results, early functional recovery and shorter admissions.

In this review we present an evidence-based summary of some common interventions and methods, including pre-operative patient education, pre-emptive analgesia, local infiltration analgesia, pre-operative nutrition, the use of pulsed electromagnetic fields, peri-operative rehabilitation, wound dressings, different surgical techniques, minimally invasive surgery and fast-track joint replacement units.

Aims

The highly cross-linked polyethylene Exeter RimFit flanged cemented acetabular component was introduced in the United Kingdom in 2010. This study aimed to examine the rates of emergence of radiolucent lines observed when the Rimfit acetabular component was implanted at total hip arthroplasty (THA) using two different techniques: firstly, the ‘rimcutter’ technique in which the flange sits on a pre-prepared acetabular rim; and secondly, the ‘trimmed flange’ technique in which the flange is trimmed and the acetabular component is seated inside the rim of the acetabulum.
